Many classes have shortcut names used when creating (instantiating) a class with a
configuration object. The shortcut name is referred to as an alias (or xtype if the
class extends Ext.Component). The alias/xtype is listed next to the class name of
applicable classes for quick reference.
Framework classes or their members may be specified as private or protected. Else,
the class / member is public. Public, protected, and private are access
descriptors used to convey how and when the class or class member should be used.
Public classes and class members are available for use by any other class or application code and may be relied upon as a stable and persistent within major product versions. Public classes and members may safely be extended via a subclass.
Protected class members are stable public members intended to be used by the
owning class or its subclasses. Protected members may safely be extended via a subclass.
Private classes and class members are used internally by the framework and are not intended to be used by application developers. Private classes and members may change or be omitted from the framework at any time without notice and should not be relied upon in application logic.
static label next to the
method name. *See Static below.Below is an example class member that we can disect to show the syntax of a class member (the lookupComponent method as viewed from the Ext.button.Button class in this case).
Let's look at each part of the member row:
lookupComponent in this example)( item ) in this example)Ext.Component in this case). This may be omitted for methods that do not
return anything other than undefined or may display as multiple possible values
separated by a forward slash / signifying that what is returned may depend on the
results of the method call (i.e. a method may return a Component if a get method calls is
successful or false if unsuccessful which would be displayed as
Ext.Component/Boolean).PROTECTED in
this example - see the Flags section below)Ext.container.Container in this example). The source
class will be displayed as a blue link if the member originates from the current class
and gray if it is inherited from an ancestor or mixed-in class.view source in the example)item : Object in the example).undefined a "Returns" section
will note the type of class or object returned and a description (Ext.Component in the
example)Available since 3.4.0 - not pictured in
the example) just after the member descriptionDefaults to: false)The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.

Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type (this count is updated as filters are applied). Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.
Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.
Your page history is kept in localstorage and displayed (using the available real estate) just below the top title bar. By default, the only search results shown are the pages matching the product / version you're currently viewing. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. This will show all recent pages in the history bar for all products / versions.
Within the history config menu you will also see a listing of your recent page visits. The results are filtered by the "Current Product / Version" and "All" radio options. Clicking on the button will clear the history bar as well as the history kept in local storage.
If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled. When checked, the product/version for each historic page will show alongside the page name in the history bar. Hovering the cursor over the page names in the history bar will also show the product/version as a tooltip.
Both API docs and guides can be searched for using the search field at the top of the page.
On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.
The checkbox at the bottom of the API class navigation tree filters the class list to include or exclude private classes.
Clicking on an empty search field will show your last 10 searches for quick navigation.
Each API doc page (with the exception of Javascript primitives pages) has a menu view of metadata relating to that class. This metadata view will have one or more of the following:
Ext.button.Button class has an alternate class name of Ext.Button). Alternate class
names are commonly maintained for backward compatibility.Runnable examples (Fiddles) are expanded on a page by default. You can collapse and expand example code blocks individually using the arrow on the top-left of the code block. You can also toggle the collapse state of all examples using the toggle button on the top-right of the page. The toggle-all state will be remembered between page loads.
Class members are collapsed on a page by default. You can expand and collapse members using the arrow icon on the left of the member row or globally using the expand / collapse all toggle button top-right.
Viewing the docs on narrower screens or browsers will result in a view optimized for a smaller form factor. The primary differences between the desktop and "mobile" view are:
The class source can be viewed by clicking on the class name at the top of an API doc page. The source for class members can be viewed by clicking on the "view source" link on the right-hand side of the member row.

A column for simple Ext.grid.cell.Texts.
DOM tabIndex attribute to set on the active Focusable child of this container when using the "Roaming tabindex" technique.
Defaults to:
0
The item from the cfg-items collection that will be active first. This is usually only meaningful in a Ext.layout.Card, where only one item can be active at a time. If passes a string, it will be assumed to be a Ext.ComponentQuery selector.
Defaults to:
0
Sets the alignment of the header and rendered columns.
Possible values are: 'left', 'center', and 'right'.
Defaults to:
'left'
Set this to true
to enable focusing disabled child items via keyboard.
Defaults to:
false
A flag indicating that this component should be above its floated siblings.
This may be a positive number to prioritize the ordering of multiple visible always on top components.
This may be set to a negative number to prioritize a component to the bottom of the z-index stack.
Defaults to:
false
Available since: 6.2.0
An object containing ARIA attributes to be set
on this Component's ARIA element. Use this to set the attributes that cannot be
determined by the Component's state, such as aria-live, aria-flowto, etc.
Note that this config is only meaningful at the Component rendering time, and setting it after that will do nothing.
Defaults to:
null
Sets the value of ariaAttributes
ariaAttributes : Object
DOM selector for a child element that is to be used
as description for this Component, set in aria-describedby attribute.
The selector works the same way as ariaLabelledBy.
ARIA label for this Component. It is best to use
ariaLabelledBy option instead, because screen readers prefer
aria-labelledby attribute to aria-label. ariaLabel and
ariaLabelledBy config options are mutually exclusive.
DOM selector for a child element that is to be used
as label for this Component, set in aria-labelledby attribute.
If the selector is by id, the label element can be any existing element,
not necessarily a child of the main Component element.
ariaLabelledBy and ariaLabel config options are
mutually exclusive, and ariaLabelledBy has the higher precedence.
If true, child items will be destroyed as soon as they are removed
from this container.
Defaults to:
true
May be set to false for improved layout performance if auto-sizing is not required.
Some versions of Safari, both desktop and mobile, have very slow performance if the application has deeply nested containers due to the following WebKit bug: https://bugs.webkit.org/show_bug.cgi?id=150445
Applications that experience performance issues in the affected versions of
Safari may need to turn off autoSizing globally for all Ext.Container instances
by placing the following override in the application's "overrides" directory:
Ext.define('MyApp.overrides.Container', {
override: 'Ext.Container',
config: {
autoSize: false
}
});
Once auto-sizing support has turned off by default, it can be selectively
turned back on only on those container instances that explicitly need auto-sizing
behavior by setting autoSize to true.
This option can also be used to allow items to be sized in percentage units as a workaround for the following browser bug: https://bugs.webkit.org/show_bug.cgi?id=137730
To illustrate, the following example should render a 200px by 200px green box
(the container) with a yellow box inside of it (the child item). The child
item's height and width are both set to '50%' so the child should render
exactly 100px by 100px in size.
All browsers except for Safari render the previous example correctly, but
Safari does not assign a height to the component. To make percentage-sized
items work in Safari, simply set autoSize to false on the container.
Since the underlying implementation works by absolutely positioning the container's
body element, this option can only be used when the container is not
"shrink wrapping" the content in either direction. When autoSize is
set to false, shrink wrapped dimension(s) will collapse to 0.
Defaults to:
true
If true, then, when showBy or alignTo fallback on
constraint violation only takes place along the major align axis.
That is, if alignment "l-r" is being used, and axisLock: true is used, then if constraints
fail, only fallback to "r-l" is considered.
Defaults to:
null
Setting this config option adds or removes data bindings for other configs.
For example, to bind the title config:
var panel = Ext.create({
xtype: 'panel',
bind: {
title: 'Hello {user.name}'
}
});
To dynamically add bindings:
panel.setBind({
title: 'Greetings {user.name}!'
});
To remove bindings:
panel.setBind({
title: null
});
The bind expressions are presented to Ext.app.ViewModel#bind. The
ViewModel instance is determined by lookupViewModel.
Note: If bind is passed as a string, it will use the Ext.Component#property-defaultBindProperty for the binding.
Defaults to:
null
Enables or disables bordering on this component. The following values are accepted:
null or `true (default): Do nothing and allow the border to be specified by the theme.false: suppress the default border provided by the theme.Please note that enabling bordering via this config will not add a border-color
or border-style CSS property to the component; you provide the border-color
and border-style via CSS rule or style configuration
(if not already provide by the theme).
Ext.Viewport.add({
centered: true,
width: 100,
height: 100,
style: 'border: 1px solid blue;'
// ...
});
Ext.Viewport.add({
centered: true,
width: 100,
height: 100,
cls: 'my-component'
// ...
});
And your CSS file:
.my-component {
border: 1px solid red;
}
Defaults to:
null
The absolute bottom position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
Explicitly setting this value will make this Component become 'positioned', which means it will no
longer participate in the layout of the Container that it resides in.
Defaults to:
null
Animation to be used during transitions of cards.
This method has been REMOVED since 2.0.0
The config object used to create Ext.grid.cell.Base for this column.
By default, cells use the Ext.grid.cell.Cell xtype. To create
a different type of cell, simply provide this config and the desired xtype.
Defaults to:
{
xtype: 'gridcell'
}
Configure this as true to have this Component centered within its Container.
Setting this value to true will make this Component become 'positioned', which means it will no
longer participate in the layout of the Container that it resides in.
Defaults to:
false
The CSS class to add to this widget's element, in addition to the baseCls. In many cases, this property will be specified by the derived widget class. See userCls for adding additional CSS classes to widget instances (such as items in a Ext.Container).
Defaults to:
null
The sub columns within this column/header container.
Defaults to:
null
Returns all the leaf columns, regardless of visibility
selector : Object
The computed width for this column, may come from either width or flex.
Defaults to:
null
A specification of the constraint to apply when showBy or alignTo is called to align a floated or positioned component.
Defaults to the parent container for positioned components (components which have their top, right, bottom or left set to move them out of their container's layout flow).
Defaults to the viewport for floated components.
May be a Ext.ComponentQuery selector to find an ancestor component to constrain within.
May be false to specify that constraining is not applied.
You may also specify an element, or a Ext.util.Region
Defaults to:
null
Returns the value of constrainAlign
Sets the value of constrainAlign
constrainAlign : String / Ext.util.Region / Ext.dom.Element
The configured element will automatically be added as the content of this component. When you pass a string, we expect it to be an element id. If the content element is hidden, we will automatically show it.
Defaults to:
null
Returns the value of contentEl
Ext.dom.Element / HTMLElement / String
Sets the value of contentEl
contentEl : Ext.dom.Element / HTMLElement / String
Enables you to easily control Components inside this Container by listening to their events and taking some action. For example, if we had a container with a nested Disable button, and we wanted to hide the Container when the Disable button is tapped, we could do this:
We used a Ext.ComponentQuery selector to listen to the tap event on any
Ext.Button anywhere inside the Container that has the text 'Disable'.
Whenever a Component matching that selector fires the tap event our hideMe function is called. hideMe is
called with scope: this (e.g. this is the Container instance).
Defaults to:
null
A string alias, a configuration object or an instance of a ViewController for
this container. Sample usage:
Ext.define('MyApp.UserController', {
alias: 'controller.user'
});
Ext.define('UserContainer', {
extend: 'Ext.container.container',
controller: 'user'
});
// Or
Ext.define('UserContainer', {
extend: 'Ext.container.container',
controller: {
type: 'user',
someConfig: true
}
});
// Can also instance at runtime
var ctrl = new MyApp.UserController();
var view = new UserContainer({
controller: ctrl
});
Defaults to:
null
Returns the Ext.app.ViewController instance associated with this component via the controller config or setController method.
Returns this component's ViewController or null if one was not configured
Sets the value of controller
controller : String / Object / Ext.app.ViewController
The initial set of data to apply to the tpl to
update the content area of the Component.
Note: Data will be appended to any existing data.
Defaults to:
null
The name of the field in the grid's Ext.data.Store's Ext.data.Model definition from which to draw the column's value. Required.
Defaults to:
null
A default ui to use for columns in this header.
Defaults to:
null
Sets the value of defaultColumnUI
defaultColumnUI : Object
An optional config object that should not really be modified. This is used to create a default editor used by the Ext.grid.plugin.Editable plugin when no editor is specified.
Defaults to:
{
xtype: 'textfield',
required: true
}
Returns the value of defaultEditor
Note: This method will only have an implementation if the Ext.grid.plugin.Editable has been enabled on the grid.
The defaultEditor value.
Sets the default form field to be used for editing.
Note: This method will only have an implementation if the Ext.grid.plugin.Editable has been enabled on the grid.
field : Object
An object representing a field to be created. You must include the column's dataIndex as the value of the field's name property when setting the default editor field.
column.setDefaultEditor({
xtype: 'textfield',
name: column.getDataIndex()
});
this
Specifies a child Component to receive focus when this Container's method-focus method is called. Should be a valid Ext.ComponentQuery selector.
Defaults to:
null
If true, this component will be the default scope (this pointer) for events
specified with string names so that the scope can be dynamically resolved. The
component will automatically become the defaultListenerScope if a
controller is specified.
See the introductory docs for Ext.container.Container for some sample usages.
NOTE: This value can only be reliably set at construction time. Setting it after that time may not correctly rewire all of the potentially effected listeners.
Defaults to:
false
Sets the value of defaultListenerScope
defaultListenerScope : Boolean
A set of default configurations to apply to all child Components in this Container. It's often useful to specify defaults when creating more than one items with similar configurations. For example here we can specify that each child is a panel and avoid repeating the xtype declaration for each one:
Defaults to:
null
The default weight for tools in the header.
Defaults to:
{
toggle: 10,
gear: 20,
prev: 30,
next: 40,
left: 50,
right: 60,
down: 70,
up: 80,
refresh: 90,
plus: 100,
minus: 110,
search: 120,
save: 130,

close: 230
}
Available since: 6.5.0
Sets the value of defaultToolWeights
defaultToolWeights : Object
The default Ext.Component of child Components to create in this Container when a child item is specified as a raw configuration object, rather than as an instantiated Component.
Defaults to:
null
A width to apply if the flex or width configurations have not been specified.
Defaults to:
100
Available since: 6.2.0
Set to true to call show and false to call hide. Unlike the hidden
config, changing this config will potentially involve animations to show or
hide the component.
Defaults to:
null
Available since: 6.5.0
The dock position of this component in its container. Can be left, top, right or bottom.
Notes
You must use a HTML5 doctype for docked bottom to work. To do this, simply add the following code to the HTML file:
<!doctype html>
So your index.html file should look a little like this:
<!doctype html>
<html>
<head>
<title>MY application title</title>
...
Defaults to:
null
Set to true to allow this component to be dragged. This can also be the config
object for the Ext.drag.Source that will manage the drag.
Defaults to:
null
Sets the value of draggable
draggable : Boolean / Object / Ext.drag.Source
Set this to true to make this column editable. Only applicable if the grid is using an Ext.grid.plugin.Editable plugin.
Defaults to:
null
An optional xtype or config object for a Ext.field.Field to use for editing. Only applicable if the grid is using an Ext.grid.plugin.Editable plugin. Note also that editable has to be set to true if you want to make this column editable. If this configuration is not set, and editable is set to true, the defaultEditor is used.
Defaults to:
null
Returns the value of editor
Note: This method will only have an implementation if the Ext.grid.plugin.Editable has been enabled on the grid.
The editor value.
Sets the form field to be used for editing.
Note: This method will only have an implementation if the Ext.grid.plugin.Editable has been enabled on the grid.
field : Object
An object representing a field to be created. You must include the column's dataIndex as the value of the field's name property when setting the editor field.
column.setEditor({
xtype: 'textfield',
name: column.getDataIndex()
});
this
Animation effect to apply when the Component is being shown. Typically you want to use an inbound animation type such as 'fadeIn' or 'slideIn'.
Defaults to:
null
Deprecated since version 2.0.0
Please use showAnimation instead.
Sets the value of enterAnimation
enterAnimation : String / Mixed
A map of event type to the corresponding handler method name. This is used internally by native event handling mechanism.
Defaults to:
{
focus: 'handleFocusEvent',
blur: 'handleBlurEvent'
}
Animation effect to apply when the Component is being hidden.
Defaults to:
null
Deprecated since version 2.0.0
Please use hideAnimation instead. Typically you want to use an
outbound animation type such as 'fadeOut' or 'slideOut'.
Sets the value of exitAnimation
exitAnimation : String / Mixed
During data export via the Ext.grid.plugin.Exporter plugin the data for this column could be formatted in multiple ways:
exportStyle.formatformatter if no exportStyle is definedexportRendererIf you want to use the renderer defined on this column then set exportRenderer
to true. Beware that this should only happen if the renderer deals only with
data on the record or value and it does NOT style the cell or returns an html
string.
{
xtype: 'numbercolumn',
dataIndex: 'price',
text: 'Price',
renderer: function (value, record, dataIndex, cell, column) {
return Ext.util.Format.currency(value);
},
exportRenderer: true
}
If you don't want to use the renderer during export but you still want to format
the value in a special way then you can provide a function to exportRenderer or
a string (which is a function name on the ViewController).
The provided function has the same signature as the renderer.
{
xtype: 'numbercolumn',
dataIndex: 'price',
text: 'Price',
exportRenderer: function (value, record, dataIndex, cell, column) {
return Ext.util.Format.currency(value);
}
}
{
xtype: 'numbercolumn',
dataIndex: 'price',
text: 'Price',
exportRenderer: 'exportAsCurrency' // this is a function on the ViewController
}
If exportStyle.format, formatter and exportRenderer are all defined on the
column then the exportStyle wins and will be used to format the data for this
column.
Defaults to:
false
A style definition that is used during data export via the Ext.grid.plugin.Exporter. This style will be applied to the columns generated in the exported file.
You could define it as a single object that will be used by all exporters:
{
xtype: 'numbercolumn',
dataIndex: 'price',
exportStyle: {
format: 'Currency',
alignment: {
horizontal: 'Right'
},
font: {
italic: true
}
}
}
You could also define it as an array of objects, each object having a type that specifies by
which exporter will be used:
{
xtype: 'numbercolumn',
dataIndex: 'price',
exportStyle: [{
type: 'html', // used by the html exporter
format: 'Currency',
alignment: {
horizontal: 'Right'
},
font: {
italic: true
}
},{
type: 'csv', // used by the `csv` exporter
format: 'General'
}]
}
Or you can define it as an array of objects that has:
type key that is considered the style to use by all exportersobjects with the type key defined that are exceptions of the above rule
{
xtype: 'numbercolumn',
dataIndex: 'price',
exportStyle: [{
// no type defined means this is the default
format: 'Currency',
alignment: {
horizontal: 'Right'
},
font: {
italic: true
}
},{
type: 'csv', // only the CSV exporter has a special style
format: 'General'
}]
}
Defaults to:
null
Returns the value of exportStyle
Sets the value of exportStyle
exportStyle : Ext.exporter.file.Style / Ext.exporter.file.Style[]
This config is similar to exportRenderer but is applied to summary records.
Defaults to:
false
Returns the value of exportSummaryRenderer
The flex of this item if this item item is inside a Ext.layout.HBox or Ext.layout.VBox layout.
You can also update the flex of a component dynamically using the Ext.layout.FlexBox#setItemFlex method.
When supplied as a string or number this option supports the same syntax as CSS href="https://developer.mozilla.org/en-US/docs/Web/CSS/flex" class="external-link" target="_blank">https://developer.mozilla.org/en-US/docs/Web/CSS/flex flex. For example:
flex: '1 2 auto'
sets flex-grow property to 0, flex-shrink to 2 and flex-basis to
'auto'.
The default flex-shrink value for box layout items is set to 0 in the
stylesheet, which is different from the browser's default flex-shrink value
of 1. This accommodates the majority use case for applications since where
non-flexed components are typically not expected to shrink smaller than their
default size.
For convenience when only a single number is supplied it is used as the value
for both flex-grow and flex-shrink, for example flex: 3 is the same as
flex: '3 3'
An object form is also accepted:
flex: {
grow: 1,
shrink: 2,
basis: 'auto'
}
When the object form is supplied shrink always defaults to 0 regardless
of the value of grow.
Although 'auto' is the default value for flex-basis, flex-basis defaults to 0%
when flex is supplied as a single numeric or string value (e.g. flex: 1). If
this behavior is not desired either explicitly set flex-basis to 'auto' or use
the object form to set only grow and/or shrink:
flex: {
grow: 2
}
Defaults to:
null
A Component may be floated above all other components in the application. This means that the component is absolutely positioned, and will move to the front and occlude other sibling floated component if clicked.
A Floated component may have floated descendants. It will bring these decendants to the front with it when brought to the front of its sibling floated components.
By default, descendant floated components are all positioned using the viewport coordinate system. To make a floating
component a positioning parent for descendants, and have the ancestors positioned relatively, configure the parent
floated component with cfg-relative: true.
Defaults to:
false
Available since: 6.2.0
Enable or disable navigation with arrow keys for this FocusableContainer. This option may be useful with nested FocusableContainers, when only the root container should handle keyboard events.
Defaults to:
false
CSS class that will be added to focused component's focusClsEl, and removed when component blurs.
Defaults to:
'x-focused'
This config accepts a format specification as would be used in a Ext.Template
formatted token. For example 'round(2)' to round numbers to 2 decimal places
or 'date("Y-m-d")' to format a Date.
In previous releases the renderer config had limited abilities to use one
of the Ext.util.Format methods but formatter now replaces that usage and
can also handle formatting parameters.
When the value begins with "this." (for example, "this.foo(2)"), the
implied scope on which "foo" is found is the scope config for the column.
If the scope is not given, or implied using a prefix of "this", then either the
ViewController or the closest ancestor component configured
as defaultListenerScope is assumed to be the object with the method.
Defaults to:
null
Available since: 6.2.0
Force the component to take up 100% width and height available, by adding it to Ext.Viewport.
If the grid is grouped, and uses a Ext.grid.plugin.ViewOptions plugin this option may be used to disable the option to group by this column. By default, the group option is enabled.
Defaults to:
true
A grouper config object to apply when the standard grouping user interface is is invoked. This option is, for example, available in the column's header menu.
Note that a grouper may also be specified as a function which accepts two records to compare.
A Ext.app.ViewController method can be used like so:
grouper: 'groupMethodName'
This is different then a sorter in that the grouper method is used to
set the groupFn. This string returned
by this method is used to determine group membership. To specify both the
grpoupFn and the sorterFn:
grouper: {
groupFn: 'groupMethodName'
sorterFn: 'sorterMethodName
}
Defaults to:
null
Available since: 6.5.0
Returns the value of grouper
Function / String / Object / Ext.util.Grouper
Sets the value of grouper
grouper : Function / String / Object / Ext.util.Grouper
This config allows a column to replace the default template supplied by the grid's groupHeader.tpl.
Defaults to:
null
Available since: 6.5.0
Sets the value of groupHeaderTpl
groupHeaderTpl : String / String[] / Ext.XTemplate
The height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
By default, if this is not explicitly set, this Component's element will simply have its own natural size.
If set to auto, it will set the width to null meaning it will have its own natural size.
Defaults to:
null
False to prevent the user from hiding this column.
Defaults to:
true
Available since: 6.5.0
Animation effect to apply when the Component is being hidden. Typically you want to use an outbound animation type such as 'fadeOut' or 'slideOut'. For more animations, check the Ext.fx.Animation#type config.
Defaults to:
null
Sets the value of hideAnimation
hideAnimation : String / Mixed
A String which specifies how this component's DOM element will be hidden. The accepted values are any of these:
'clip' : Hide using clip.'display' : Hide using display.'offsets' : Hide using positioning offsets.'opacity' : Hide using opacity.'visibility' : Hide using visibility.Hiding using display results in having no dimensions as well as resetting
scroll positions to 0.
The other modes overcome this but may have different trade-offs in certain circumstances.
Defaults to:
'display'
Available since: 6.5.0
Returns the value of hideMode
'clip' / 'display' / 'offsets' / 'opacity' / 'visibility'
Sets the value of hideMode
hideMode : 'clip' / 'display' / 'offsets' / 'opacity' / 'visibility'
When using a modal Component, setting this to true
will hide the modal mask and the Container when the mask is tapped on.
Defaults to:
null
The Ext.menu.CheckItem to be used by the owning grid's header menu to hide or show this column.
Defaults to:
{
xtype: 'menucheckitem'
}
Available since: 6.5.0
Sets the value of hideShowMenuItem
hideShowMenuItem : Ext.menu.CheckItem / Object
Optional HTML content to render inside this Component, or a reference to an existing element on the page.
Defaults to:
null
Returns the value of html
String / Ext.dom.Element / HTMLElement
The unique id of this component instance.
It should not be necessary to use this configuration except for singleton objects in your application. Components created with an id may be accessed globally using Ext.getCmp.
Instead of using assigned ids, use the itemId config, and Ext.ComponentQuery which provides selector-based searching for Sencha Components analogous to DOM querying. The Ext.Container class contains shortcut methods to query its descendant Components by selector.
Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent.
Note: to avoid complications imposed by a unique id also see itemId.
Defaults to an auto-assigned id.
Retrieves the id of this component. Will autogenerate an id if one has not already been set.
id
Setting to true prevents this column from being used by plugins such as
Ext.grid.plugin.ViewOptions or Ext.grid.plugin.Summary. It is
intended for special columns such as the row number or checkbox selection.
Defaults to:
false
This flag indicates that this column will be ignored when grid data is exported.
When grid data is exported you may want to export only some columns that are important and not everything. You can set this flag on any column that you want to be ignored during export.
This is used by Ext.grid.plugin.Exporter.
Defaults to:
false
DOM tabIndex attribute to set on inactive Focusable children of this container when using the "Roaming tabindex" technique. This value rarely needs to be changed from its default.
Defaults to:
-1
A string to add to the immediate parent element of the inner items of this
container. That is, items that are not docked, positioned or floated. In
some containers, positioned items may be in this same element.
Defaults to:
null
Available since: 6.5.0
{String/String[]
An extra CSS class or classes to augment the classCls on an individual instance
Defaults to:
null
Available since: 6.5.0
An itemId can be used as an alternative way to get a reference to a component when no object reference is
available. Instead of using an id with Ext#getCmp, use itemId with
Ext.Container#getComponent which will retrieve itemId's or id's. Since itemId's are an
index to the container's internal MixedCollection, the itemId is scoped locally to the container - avoiding
potential conflicts with Ext.ComponentManager which requires a unique id.
Also see id, Ext.Container#query, Ext.Container#down and Ext.Container#child.
Defaults to:
undefined
The child items to add to this Container. This is usually an array of Component configurations or instances, for example:
This may also be specified as an object, the property names of which are itemIds, and the property values
are child Component config objects, for example:
Defaults to:
null
An object containing handlers for keyboard events. The property names of this object are the key name and any modifiers. The values of the properties are the descriptors of how to handle each event.
The handler descriptor can be simply the handler function (either the literal function or the method name), or it can be an object with these properties:
handler: The function or its name to call to handle the event.scope: The this pointer context (can be "this" or "controller").event: An optional override of the key event to which to listen.Important: Calls to setKeyMap do not replace the entire keyMap but
instead update the provided mappings. That is, unless null is passed as the
value of the keyMap which will clear the keyMap of all entries.
Defaults to:
null
scope : String
The default scope to apply to key handlers
which do not specify a scope. This is processed the same way as the scope of
cfg-listeners. It defaults to the "controller", but using 'this'
means that an instance method will be used.
Enables or disables processing keys in the keyMap. This value starts as
null and if it is null when initKeyMap is called, it will automatically
be set to true. Since initKeyMap is called by Ext.Component at the
proper time, this is not something application code normally handles.
Defaults to:
null
The name of the member that should be used to listen for keydown/keypress events. This is intended to be controlled at the class level not per instance.
Defaults to:
'el'
Configuration for this Container's layout. Example:
Defaults to:
'auto'
The absolute left position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
Explicitly setting this value will make this Component become 'positioned', which means it will no
longer participate in the layout of the Container that it resides in.
Defaults to:
null
A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once.
DOM events from Ext JS Ext.Component
While some Ext JS Component classes export selected DOM events (e.g. "click", "mouseover" etc), this is usually
only done when extra value can be added. For example the DataView's itemclick event passing the node clicked on. To access DOM events directly from a
child element of a Component, we need to specify the element option to identify the Component property to add a
DOM listener to:
new Ext.panel.Panel({
width: 400,
height: 200,
dockedItems: [{
xtype: 'toolbar'
}],
listeners: {
click: {
element: 'el', //bind to the underlying el property on the panel
fn: function(){ console.log('click el'); }
},
dblclick: {
element: 'body', //bind to the underlying body property on the panel
fn: function(){ console.log('dblclick body'); }
}
}
});
An alias for addListener. In versions prior to 5.1, listeners had a generated setter which could be called to add listeners. In 5.1 the listeners config is not processed using the config system and has no generated setter, so this method is provided for backward compatibility. The preferred way of adding listeners is to use the on method.
listeners : Object
The listeners
true to enable border management of docked items. When enabled, borders of docked
items will collapse where they meet to avoid duplicated borders.
Defaults to:
false
The margin to use on this Component. Can be specified as a number (in which case all edges get the same margin) or a CSS string like '5 10 10 10'
Defaults to:
null
A configuration to allow you to mask this container.
You can optionally pass an object block with and xtype of loadmask, and an optional message value to
display a loading mask. Please refer to the Ext.LoadMask component to see other configurations.
Alternatively, you can just call the setter at any time with true/false to show/hide the mask:
setMasked(true); //show the mask
setMasked(false); //hides the mask
There are also two convenient methods, method-mask and unmask, to allow you to mask and unmask this container at any time.
Remember, the Ext.Viewport is always a container, so if you want to mask your whole application at anytime, can call:
Ext.Viewport.setMasked({
xtype: 'loadmask',
message: 'Hello'
});
Defaults to:
null
Returns the value of masked
Boolean / Object / Ext.Mask / Ext.LoadMask
Sets the value of masked
masked : Boolean / Object / Ext.Mask / Ext.LoadMask
The maximum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
If set to auto, it will set the width to null meaning it will have its own natural size.
Note that this config will not apply if the Component is 'positioned' (absolutely positioned or centered)
Defaults to:
null
The maximum width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
If set to auto, it will set the width to null meaning it will have its own natural size.
Note that this config will not apply if the Component is 'positioned' (absolutely positioned or centered)
Defaults to:
null
The minimum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
If set to auto, it will set the width to null meaning it will have its own natural size.
Defaults to:
null
The minimum width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
If set to auto, it will set the width to null meaning it will have its own natural size.
Defaults to:
null
true to make this Component modal. This will create a mask underneath the Component
that covers its parent and does not allow the user to interact with any other Components until this
Component is dismissed.
Defaults to:
null
This config enables binding to your Ext.data.Model#validators. This
is only processed by form fields (e.g., Ext.field.*) at present, however, this
setting is inherited and so can be set on a parent container.
When set to true by a component (or by an ancestor container), the validators
of for any {@Ext.data.Model record} fields will be used wherever the value is
bound to such data fields.
While this config can be set arbitrarily high in the component hierarchy, doing
so can create a lot overhead if most of your form fields do not actually rely on
validators in your data model.
Using this setting for a form that is bound to an Ext.data.Model might look
like this:
{
xtype: 'panel',
modelValidation: true,
items: [{
xtype: 'textfield',
bind: '{theUser.firstName}'
},{
xtype: 'textfield',
bind: '{theUser.lastName}'
},{
xtype: 'textfield',
bind: '{theUser.phoneNumber}'
},{
xtype: 'textfield',
bind: '{theUser.email}'
}]
}
Defaults to:
null
Available since: 6.5.0
Set to true for this component's name property to be tracked by its containing
nameHolder.
Defaults to:
false
When true child components are tracked by their name property and can be
retrieved using the lookupName method.
Defaults to:
false
The padding to use on this Component. Can be specified as a number (in which case all edges get the same padding) or a CSS string like '5 10 10 10'
Defaults to:
null
This config describes one or more plugin config objects used to create plugin instances for this component.
Plugins are a way to bundle and reuse custom functionality. Plugins should extend
Ext.plugin.Abstract but technically the only requirement for a valid plugin
is that it contain an init method that accepts a reference to its owner. Once
a plugin is created, the owner will call the init method, passing a reference
to itself. Each plugin can then call methods or respond to events on its owner
as needed to provide its functionality.
This config's value can take several different forms.
The value can be a single string with the plugin's Ext.enums.Plugin:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: 'listpaging'
});
It can also be an array of plugin aliases:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: ['listpaging', 'pullrefresh']
});
An array can also contain elements that are config objects with a type
property holding the type alias:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: ['pullrefresh', {
type: 'listpaging',
autoPaging: true
}]
});
A final, yet very useful form (new in version 6.5) is the keyed-object form:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: {
pullrefresh: true,
listpaging: {
autoPaging: true,
weight: 10
}
}
});
In this last form, the keys are id's as well as the default type alias. The
advantage of this form is that the value of the plugins is merged by base
class to derived class and finally to the instance configuration. This allows
classes to define a set of plugins and allow derived classes or instantiators
to configure or disable these plugins. This merge behavior is a feature of the
config.
In the above examples, the string "listpaging" is the type alias for
Ext.dataview.plugin.ListPaging. The full alias includes the "plugin." prefix
(i.e., 'plugin.listpaging').
Defaults to:
null
Returns the value of plugins
Sets the value of plugins
plugins : Array / Ext.enums.Plugin / Object / Ext.plugin.Abstract
One or more names of config properties that this component should publish to its ViewModel. Generally speaking, only properties defined in a class config block (including ancestor config blocks and mixins) are eligible for publishing to the viewModel. Some components override this and publish their most useful configs by default.
Note: We'll discuss publishing properties not found in the config block below.
Values determined to be invalid by component (often form fields and model validations) will not be published to the ViewModel.
This config uses the cfg-reference to determine the name of the data
object to place in the ViewModel. If reference is not set then this config
is ignored.
By using this config and cfg-reference you can bind configs between
components. For example:
...
items: [{
xtype: 'textfield',
reference: 'somefield', // component's name in the ViewModel
publishes: 'value' // value is not published by default
},{
...
},{
xtype: 'displayfield',
bind: 'You have entered "{somefield.value}"'
}]
...
Classes must provide this config as an Object:
Ext.define('App.foo.Bar', {
publishes: {
foo: true,
bar: true
}
});
This is required for the config system to properly merge values from derived classes.
For instances this value can be specified as a value as show above or an array or object as follows:
{
xtype: 'textfield',
reference: 'somefield',
publishes: [
'value',
'rawValue',
'dirty'
]
}
// This achieves the same result as the above array form.
{
xtype: 'textfield',
reference: 'somefield',
publishes: {
value: true,
rawValue: true,
dirty: true
}
}
In some cases, users may want to publish a property to the viewModel that is not found in a class config block. In these situations, you may utilize publishState if the property has a setter method. Let's use setFieldLabel as an example:
setFieldLabel: function(fieldLabel) {
this.callParent(arguments);
this.publishState('fieldLabel', fieldLabel);
}
With the above chunk of code, fieldLabel may now be published to the viewModel.
Defaults to:
null
Available since: 5.0.0
A model instance which updates the Component's html based on it's tpl. Similar to the data configuration, but tied to to a record to make allow dynamic updates. This must be a model instance and not a configuration of one.
Defaults to:
null
Specifies a name for this component inside its component hierarchy. This name must be unique within its view or its Ext.app.ViewController. See the documentation in Ext.container.Container for more information about references.
Note: Valid identifiers start with a letter or underscore and are followed by zero or more additional letters, underscores or digits. References are case sensitive.
Defaults to:
null
If true, this container will be marked as being a point in the hierarchy where
references to items with a specified reference config will be held. The container
will automatically become a referenceHolder if a controller is specified.
See the introductory docs for Ext.container.Container for more information about references & reference holders.
Defaults to:
false
Only valid when a component is cfg-floated
Configure this as true if you require descendant floated components to be positioned relative to this
component's coordinate space, not the viewport's coordinate space.
Note: The coordinate space is this Component's encapsulating element's area. Not that of the inner element in which static child items are rendered by the layout.
Defaults to:
false
Available since: 6.2.0
A renderer is a method which can be used to transform data (value, appearance, etc.) before it is rendered.
For example:
{
text: 'Some column',
dataIndex: 'fieldName',
renderer: function (value, record) {
if (value === 1) {
return '1 person';
}
return value + ' people';
}
}
If a string is supplied, it should be the name of a renderer method from the appropriate Ext.app.ViewController.
This config is only processed if the cell type is the default of Ext.grid.cell.Cell.
Note See Ext.grid.Grid documentation for other, better alternatives to rendering cell content.
Defaults to:
null
value : Object
The data value for the current cell.
record : Ext.data.Model
The record for the current row.
dataIndex : Number
The dataIndex of the current column.
cell : Ext.grid.cell.Base
The current cell.
column : Ext.grid.column.Column
The current column.
return : String
The HTML string to be rendered. Note: to
render HTML into the cell, you will have to configure the column's cell
with encodeHtml: false
Optional element to render this Component to. Not required if this component is an item of a Container of a Container.
Defaults to:
null
Passed in from the owning grid's own configuration
Defaults to:
null
Sets the value of reserveScrollbar
reserveScrollbar : Object
When true, FocusableContainer
will reset last focused position whenever focus leaves the container.
Subsequent tabbing into the container will always focus the first eligible
child item.
When false, subsequent tabbing into the container will focus the child
item that was last focused before.
Defaults to:
false
False to prevent the column from being resizable. Note that this configuration only works when the Ext.grid.plugin.ColumnResizing plugin is enabled on the Ext.grid.Grid.
Defaults to:
true
The absolute right position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
Explicitly setting this value will make this Component become 'positioned', which means it will no
longer participate in the layout of the Container that it resides in.
Defaults to:
null
Set to truthy, Color or Object value for the ripple.
Defaults to:
null
Available since: 6.5.0
color : String
The background color of the ripple.
position : Array
Position for the ripple to start at [x,y]. Determines if a Ripple effect should happen whenever this element is pressed.
For example: { ripple: true }
Or:
{
ripple: {
color: 'red'
}
}
For complex components, individual elements can suppress ripples by adding the
x-no-ripple class to disable rippling for a tree of elements.
Defaults to:
true
Available since: 6.5.0
Sets the value of scratchCell
scratchCell : Ext.grid.cell.Cell / Object
Configuration options to make this Component scrollable. Acceptable values are:
true to enable auto scrolling.false (or null) to disable scrolling - this is the default.x or horizontal to enable horizontal scrolling onlyy or vertical to enable vertical scrolling onlyAlso accepts a configuration object for a Ext.scroll.Scroller if
if advanced configuration is needed.
The getter for this config returns the Ext.scroll.Scroller instance. You can use the Scroller API to read or manipulate the scroll position:
// scrolls the component to 5 on the x axis and 10 on the y axis
component.getScrollable().scrollTo(5, 10);
Defaults to:
null
If provided this creates a new Session instance for this component. If this
is a Container, this will then be inherited by all child components.
To create a new session you can specify true:
Ext.create({
xtype: 'viewport',
session: true,
items: [{
...
}]
});
Alternatively, a config object can be provided:
Ext.create({
xtype: 'viewport',
session: {
...
},
items: [{
...
}]
});
Defaults to:
null
Sets the value of session
session : Boolean / Object / Ext.data.Session
Configure as true for the component to have a drop shadow. 'false' will suppress any default shadow.
By default the theme will determine the presence of a shadow.
Defaults to:
null
Available since: 6.2.0
Only valid when a component is cfg-floated
Configure as true for the component to use an <iframe> as an underlay to ensure certain non-standard
browser plugins are occluded by this component.
Defaults to:
false
Available since: 6.2.0
Animation effect to apply when the Component is being shown. Typically you want to use an inbound animation type such as 'fadeIn' or 'slideIn'. For more animations, check the Ext.fx.Animation#type config.
Defaults to:
null
Sets the value of showAnimation
showAnimation : String / Mixed
False to disable sorting of this column. Whether local/remote sorting is used is specified in
Ext.data.Store#remoteSort.
Defaults to:
true
A sorter config object to apply when the standard sort user interface is is invoked. This is usually clicking this column header, but there are also menu options to sort ascending or descending.
Note that a sorter may also be specified as a function which accepts two records to compare.
A Ext.app.ViewController method can be used like so:
sorter: 'sorterMethodName'
Or more explicitly:
sorter: {
sorterFn: 'sorterMethodName'
}
By default sorting is based on the dataIndex but this can be adjusted
like so:
sorter: {
property: 'otherProperty'
}
Defaults to:
null
Available since: 6.5.0
Returns the value of sorter
Function / String / Object / Ext.util.Sorter
Sets the value of sorter
sorter : Function / String / Object / Ext.util.Sorter
Additional CSS styles that will be rendered into an inline style attribute when the widget is rendered.
You can pass either a string syntax:
style: 'background:red'
Or by using an object:
style: {
background: 'red'
}
When using the object syntax, you can define CSS Properties by using a string:
style: {
'border-left': '1px solid red'
}
Although the object syntax is much easier to read, we suggest you to use the string syntax for better performance.
Defaults to:
null
This config replaces the default mechanism of acquiring a summary result from the summary record. When specified, this string is the name of a summary type:
The summary is based on either the summaryDataIndex or the
dataIndex if there is no summaryDataIndex.
This config is only valid when all data is available client-side to calculate summaries.
It is generally best to allow the summary Ext.data.Model to computer summary values (and not use this config). In some cases, however, this config can be useful to isolate summary calculations to only certain grids.
To implement a custom summary for a column, use summaryRenderer.
Defaults to:
null
Available since: 6.5.0
The config object used to create Ext.grid.cell.Base in Ext.grid.SummaryRow for this column.
Defaults to:
null
For Ext.grid.SummaryRow this config overrides the normal
dataIndex to use from the summary record.
Defaults to:
null
Available since: 6.5.0
Sets the value of summaryDataIndex
summaryDataIndex : String
This summaryFormatter is similar to formatter but is called before displaying a value in the SummaryRow. The config is optional, if not specified the default calculated value is shown. The summaryFormatter is called with:
Note that this configuration only works when the grid has the Ext.grid.plugin.Summary plugin enabled.
Defaults to:
null
Sets the value of summaryFormatter
summaryFormatter : String
This summaryRenderer is called to render the value to display in a cell of a summary row. If the value of this config is a String, it is the name of the renderer method on the associated controller.
Defaults to:
null
value : Mixed
The summary value to render. This value is
retrieved from the summary record based on the summaryDataIndex or
dataIndex, or by applying the summary algorithm to
the appropriate records. While this value can be useful, it can also be ignored
and the renderer method can use the context information to determine the value
to render entirely on its own.
context : Object
The summary context object.
dataIndex : String
The data field. This will be either the summaryDataIndex if one is specified, or the normal dataIndex if not.
group : String
The Ext.data.Group
being summarized. This is null if the summary is for the whole store.
store : String
The Ext.data.Store being summarized.
If this method returns undefined, no update is made to the cell. Instead it
is assumed that the summaryRenderer has made all of the necessary changes.
Note that this configuration only works when the grid has the Ext.grid.plugin.Summary plugin enabled.
This configuration specifies the type of summary. There are several built in summary types. These call underlying methods on the store:
Any other name is assumed to be the name of a method on the associated Ext.app.ViewController.
Note that this configuration only works when the grid has the Ext.grid.plugin.Summary plugin enabled.
Defaults to:
null
Deprecated since version 6.5
Use summary or summaryRenderer instead.
DOM tabIndex attribute for this component's focusEl.
Defaults to:
null
Return the actual tabIndex for this Focusable.
tabIndex attribute value
Set the tabIndex property for this Focusable. If the focusEl is available, set tabIndex attribute on it, too.
newTabIndex : Number
new tabIndex to set
The header text to be used as innerHTML (html tags are accepted) to display in the Grid.
Note: to have a clickable header with no text displayed you can use the default of   aka .
Defaults to:
'\xa0'
True to automatically call toFront when a cfg-floated Component is shown.
Defaults to:
true
The properties of this object are shallow copied (via applyIf()
as opposed to Ext.merge() to each tool declared in the tools
config.
Defaults to:
{
xtype: 'tool',
zone: 'end'
}
An array of Ext.Tool configs or an object keyed by itemId.
Defaults to:
null
Returns the value of tools
Ext.Tool[] / Object / Object[]
The tooltip for this component - can be a string to be used as innerHTML (html tags are accepted) or Ext.tip.ToolTip config object.
The default behavior is to use a shared tip instance. The tooltip configuration is registered with the Ext.tip.Manager. To enable this, your application can set the Ext.app.Application#quickTips config, or an instance of the Ext.tip.Manager may be created manually.
To force a unique tooltip instance to be created, specify autoCreate: true on this configuration.
Configuring this with autoHide: false implies autoCreate: true so that the desired persistent
behavior can be obtained with other targets still showing the singleton instance.
Defaults to:
null
The absolute top position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
Explicitly setting this value will make this Component become 'positioned', which means it will no
longer participate in the layout of the Container that it resides in.
Defaults to:
null
Emulates the behavior of the CSS touch-action property in a cross-browser compatible manner.
Keys in this object are touch action names, and values are false to disable
a touch action or true to enable it. Accepted keys are:
panXpanYpinchZoomdoubleTapZoomAll touch actions are enabled (true) by default, so it is usually only necessary
to specify which touch actions to disable. For example, the following disables
only horizontal scrolling and pinch-to-zoom on the component's main element:
touchAction: {
panX: false,
pinchZoom: false
}
Touch actions can be specified on reference elements using the reference element name, for example:
// disables horizontal scrolling on the main element, and double-tap-zoom
// on the child element named "body"
touchAction: {
panY: false
body: {
doubleTapZoom: false
}
}
The primary motivation for setting the touch-action of an element is to prevent the browser's default handling of a gesture such as pinch-to-zoom, or drag-to-scroll, so that the application can implement its own handling of that gesture on the element. Suppose, for example, a component has a custom drag handler on its element and wishes to prevent horizontal scrolling of its container while it is being dragged:
Ext.create('Ext.Widget', {
touchAction: {
panX: false
},
listeners: {
drag: function(e) {
// implement drag logic
}
}
});
Defaults to:
null
An Ext.XTemplate, or an XTemplate definition string to use to process a Ext.data.Model data to produce a cell's rendered value.
This config is only processed if the cell type is the default of Ext.grid.cell.Cell.
Note See Ext.grid.Grid documentation for other, better alternatives to rendering cell content.
Defaults to:
null
The Ext.(X)Template method to use when updating the content area of the Component. Valid modes are:
Defaults to:
'overwrite'
This config is the default translatable type to use for this type of component.
This is not normally set on instances because it is more appropriate to just set
translatable:
items: [{
translatable: {
type: 'csstransform',
}
...
This config is more useful for a class to set the default translatable type that
will be used for any components that are translatable.
Available since: 6.5.0
This object holds a map of config properties that will update their binding
as they are modified. For example, value is a key added by form fields. The
form of this config is the same as publishes.
This config is defined so that updaters are not created and added for all bound properties since most cannot be modified by the end-user and hence are not appropriate for two-way binding.
Defaults to:
null
The ui or uis to be used on this Component
When a ui is configured, CSS class names are added to the element, created by appending the ui name(s) to each classCls and/or baseCls.
Defaults to:
null
One or more CSS classes to add to the component's primary element. This config is intended solely for use by the component instantiator (the "user"), not by derived classes.
For example:
items: [{
xtype: 'button',
userCls: 'my-button'
...
}]
Defaults to:
null
Updated by the grid to inform the header container whether it must account for a vertical scrollbar
Defaults to:
null
Sets the value of verticalOverflow
verticalOverflow : Object
The ViewModel is a data provider for this component and its children. The
data contained in the ViewModel is typically used by adding bind configs
to the components that want present or edit this data.
When set, the ViewModel is created and links to any inherited viewModel
instance from an ancestor container as the "parent". The ViewModel hierarchy,
once established, only supports creation or destruction of children. The
parent of a ViewModel cannot be changed on the fly.
If this is a root-level ViewModel, the data model connection is made to this
component's associated Ext.data.Session. This is
determined by calling getInheritedSession.
Defaults to:
null
Sets the value of viewModel
viewModel : String / Object / Ext.app.ViewModel
This value controls this item's order in a weighted Ext.Container (see parent).
Lower values gravitate towards the start of the container - the top in vertical layouts, the locale start side in horizontal layouts.
Defaults to:
0
If set to true, then child items may be specified as a object,
with each property name specifying an itemId, and the property
value being the child item configuration object.
When using this scheme, each child item may contain a weight configuration value which affects its order in this container. Lower weights are towards the start, higher weights towards the end.
Defaults to:
false
The width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
By default, if this is not explicitly set, this Component's element will simply have its own natural size.
If set to auto, it will set the width to null meaning it will have its own natural size.
Defaults to:
null
Only valid when a component is cfg-floated
The x position at which to position this component. This is usually viewport-relative. But if there is a
relative: true ancestor, it will be relative to that.
Defaults to:
0
The xtype configuration option can be used to optimize Component creation and rendering. It serves as a
shortcut to the full component name. For example, the component Ext.button.Button has an xtype of button.
You can define your own xtype on a custom Ext.Component by specifying the
alias config option with a prefix of widget. For example:
Ext.define('PressMeButton', {
extend: 'Ext.button.Button',
alias: 'widget.pressmebutton',
text: 'Press Me'
});
Any Component can be created implicitly as an object config with an xtype specified, allowing it to be declared and passed into the rendering pipeline without actually being instantiated as an object. Not only is rendering deferred, but the actual creation of the object itself is also deferred, saving memory and resources until they are actually needed. In complex, nested layouts containing many Components, this can make a noticeable improvement in performance.
// Explicit creation of contained Components:
var panel = new Ext.Panel({
// ...
items: [
Ext.create('Ext.button.Button', {
text: 'OK'
})
]
});
// Implicit creation using xtype:
var panel = new Ext.Panel({
// ...
items: [{
xtype: 'button',
text: 'OK'
}]
});
In the first example, the button will always be created immediately during the panel's initialization. With many added Components, this approach could potentially slow the rendering of the page. In the second example, the button will not be created or rendered until the panel is actually displayed in the browser. If the panel is never displayed (for example, if it is a tab that remains hidden) then the button will never be created and will never consume any resources whatsoever.
Only valid when a component is cfg-floated
The x position at which to position this component. This is usually viewport-relative. But if there is a
relative: true ancestor, it will be relative to that.
Defaults to:
0
The z-index to give this Component when it is rendered.
Not valid for cfg-floated Components. The Z ordering of cfg-floated Components is managed by ordering of the DOM elements.
Defaults to:
null
The value true causes config values to be stored on instances using a
property name prefixed with an underscore ("_") character. A value of false
stores config values as properties using their exact name (no prefix).
Defaults to:
true
Available since: 5.0.0
The value true instructs the initConfig method to only honor values for
properties declared in the config block of a class. When false, properties
that are not declared in a config block will be placed on the instance.
Defaults to:
true
Available since: 5.0.0
Matches options property names within a listeners specification object - property names which are never used as event names.
Defaults to:
{
scope: 1,
delay: 1,
buffer: 1,
onFrame: 1,
single: 1,
args: 1,
destroyable: 1,
priority: 1,
order: 1
}
We don't want the base destructor to clear the prototype because our destroyObservable handler must be called the very last. It will take care of the prototype after completing Observable destruction sequence.
Defaults to:
true
The name of the Component property that holds a reference to the Element that serves as that Component's ARIA element. This property will be replaced with the actual Element reference after rendering.
Most of the simple Components will have their main element as ariaEl.
Defaults to:
'el'
Available since: 6.0.0
Instance specific ARIA attributes to render into Component's ariaEl. This object is only used during rendering, and is discarded afterwards.
ARIA role for this Component, defaults to no role. With no role, no other ARIA attributes are set.
The base CSS class to apply to this widget's element.
Used as the prefix for ui-specific class names.
Defaults to the value of classCls or (x- + the xtype) of the widget
if classCls is null
Defaults to:
null
A CSS class to apply to the main element that will be inherited down the class hierarchy. Subclasses may override this property on their prototype to add their own CSS class in addition to the CSS classes inherited from ancestor classes via the prototype chain. For example
Ext.define('Foo', {
extend: 'Ext.Widget',
classCls: 'foo'
});
Ext.define('Bar', {
extend: 'Foo',
classCls: 'bar'
});
var bar = new Bar();
console.log(bar.element.className); // outputs 'foo bar'
Defaults to:
null
When set to true during widget class definition, that class will be the "root" for
classCls inheritance. Derived classes may set this to true to avoid
inheriting a classCls from their superclass.
Defaults to:
true
Setting this property to false will prevent nulling object references
on a Class instance after destruction. Setting this to "async" will delay
the clearing for approx 50ms.
Defaults to:
true
Available since: 6.2.0
Setting this property to true will result in setting the object's
prototype to null after the destruction sequence is fully completed.
After that, most attempts at calling methods on the object instance
will result in "method not defined" exception. This can be very helpful
with tracking down otherwise hard to find bugs like runaway Ajax requests,
timed functions not cleared on destruction, etc.
Note that this option can only work in browsers that support Object.setPrototypeOf
method, and is only available in debugging mode.
Defaults to:
false
Available since: 6.2.0
true if this currently focused element
is within this Component's or Container's hierarchy. This property is set separately
from hasFocus, and can be true when hasFocus is false.
Examples:
Text field with input element focused would be: focusable: true, hasFocus: true, containsFocus: true
Date field with drop-down picker currently focused would be: focusable: true, hasFocus: false, containsFocus: true
Form Panel with a child input field currently focused would be: focusable: false, hasFocus: false, containsFocus: true
See also hasFocus.
Defaults to:
false
This property is used to determine the property of a bind config that is just
the value. For example, if defaultBindProperty="value", then this shorthand
bind config:
bind: '{name}'
Is equivalent to this object form:
bind: {
value: '{name}'
}
The defaultBindProperty is set to "value" for form fields and to "store" for
grids and trees.
Defaults to:
'html'
This property is set to true after the destroy method is called.
Defaults to:
false
A configuration object for Ext.Element.create() that is used to create the Element template. Subclasses should avoid overriding this property and instead add elements using template.
Supports all the standard options of a Ext.Element.create() config and adds 3 additional options:
reference - this option specifies a name for Element references. These
references names become properties of the Widget instance and refer to Ext.Element
instances that were created using the template:
element: {
reference: 'element',
children: [{
reference: 'innerElement'
}]
}
After construction of a widget the reference elements are accessible as follows:
var foo = new FooWidget(),
innerEl = foo.innerElement; // an Ext.Element that wraps the innerElement
The reference attribute is optional, but all Widgets must have a 'element'
reference on some element within the template (usually the outermost one).
listeners - a standard listeners object as specified by Ext.mixin.Observable.
element: {
reference: 'element',
listeners: {
click: 'onClick'
},
children: [{
reference: 'innerElement',
listeners: {
click: 'onInnerClick'
}
}]
}
Since listeners cannot be attached without an Ext.Element reference the reference
property MUST be specified in order to use listeners.
The Widget instance is used as the scope for all listeners specified in this way,
so it is invalid to use the scope option in the listeners config since it will
always be overwritten using this.
uiCls - a suffix to be appended to the ui-specific CSS class for each ui
for this widget. These ui classes are constructed by appending the ui to each
classCls or baseCls for the widget. As such, uiCls should
never be used on the main element reference, as its uiCls is computed automatically.For example, assume a widget is defined with a cfg!ui ui of 'alt action' and a
uiCls of 'inner-el' on its innerElement reference element:
Ext.define('Doodad', {
extend: 'Ext.Widget',
xtype: 'doodad',
classCls: 'x-doodad',
ui: 'alt action',
element: {
reference: 'element',
children: [{
reference: 'innerElement',
cls: 'x-inner-el',
uiCls: 'inner-el'
}]
}
});
This would result in the following markup when rendered:
<div class="x-doodad x-doodad-alt x-doodad-action">
<div class="x-inner-el x-doodad-inner-el x-doodad-alt-inner-el x-doodad-action-inner-el"></div>
</div>
These additional classes can be used to style the reference element for a particular
ui; however, use of uiCls is not typically necessary or recommended. Reference
elements should usually be styled using simple descendant selectors:
.x-doodad-alt .x-inner-el {
color: red;
}
When there is a possibility that widgets can be nested it is best to use direct child selectors to avoid the possibility of selecting all descendants instead of just the reference element for the intended widget:
.x-doodad-alt > .x-inner-el {
color: red;
}
Only use uiCls when there is a possibility of nesting, AND there may be a variable
number of elements between the main element and the reference element in question.
For example, Ext.Container with docked items has a different number of elements
in between its element and its bodyElement than a Container without docked items
because of the wrapping elements that are dynamically added to support docking.
To ensure it does not style all descendants it must use a uiCls to style its
bodyElement:
.x-container-alt-body-el {
background: #fff;
}
Note that when uiCls is specified it also adds a class name that does not contain
the ui using just the classCls and/or baseCls as the prefix. This class name
can be used for base-level styling that does not relate to any particular UI:
.x-container-body-el {
position: relative;
}
Defaults to:
{
reference: 'element'
}
Initial suspended call count. Incremented when suspendEvents is called, decremented when resumeEvents is called.
Defaults to:
0
If this property is specified by the target class of this mixin its properties are
used to configure the created Ext.Factory.
The CSS class to add to this component when it is floated at the viewport level.
Defaults to:
"x-floated"
The CSS class to add to this component's floatWrap when it's created.
Defaults to:
"x-float-wrap"
true for keyboard interactive Components or Widgets, false otherwise.
For Containers, this property reflects interactiveness of the
Container itself, not its children. See isFocusable.
Note: It is not enough to set this property to true to make
a component keyboard interactive. You also need to make sure that
the component's focusEl is reachable via Tab key (tabbable).
See also tabIndex.
Defaults to:
false
The name of the element that FocusableContainer should bind its keyboard handler to. Similar to ariaEl, this name is resolved to the Ext.dom.Element instance after rendering.
Defaults to:
"el"
The element that will have the focusCls applied when component's focusEl is focused.
The element that will be focused when focus method is called on this component. Usually this is the same element that receives focus via mouse clicks, taps, and pressing Tab key.
Defaults to:
'el'
true if this component's focusEl is focused.
See also containsFocus.
Defaults to:
false
This object holds a key for any event that has a listener. The listener may be set directly on the instance, or on its class or a super class (via observe) or on the Ext.app.EventBus. The values of this object are truthy (a non-zero number) and falsy (0 or undefined). They do not represent an exact count of listeners. The value for an event is truthy if the event must be fired and is falsy if there is no need to fire the event.
The intended use of this property is to avoid the expense of fireEvent calls when there are no listeners. This can be particularly helpful when one would otherwise have to call fireEvent hundreds or thousands of times. It is used like this:
if (this.hasListeners.foo) {
this.fireEvent('foo', this, arg1);
}
Set to true on widgets that should inherit ui from their parent container.
This property is typically set on the class body, but can be set on an instance as long
as it is set prior to the instance being added to its container. This property is
inspected at the moment a widget is added to a container, and any UIs on the container
are added to the widget at that time. Inherited UIs are in addition to the widget's
own ui, and are updated when the container's UI changes.
Defaults to:
false
Template method to do any Focusable related initialization that does not involve event listeners creation.
Defaults to:
Ext.emptyFn
This property is set to true during the call to initConfig.
Defaults to:
false
Available since: 5.0.0
true in this class to identify an object as an instantiated Container, or subclass thereof.
Defaults to:
true
This property is set to true if this instance is the first of its class.
Defaults to:
false
Available since: 5.0.0
Set in this class to identify, at runtime, instances which are not instances of the HeaderContainer base class, but are in fact, the subclass: Ext.grid.Column.
Defaults to:
true
This value is true and is used to identify plain objects from instances of
a defined class.
Defaults to:
true
true in this class to identify an object as an instantiated Observable, or subclass thereof.
Defaults to:
true
The CSS class to add to this component should not have a border.
Defaults to:
Ext.baseCSSPrefix + 'noborder-trbl'
Called when focus moves within this Component's hierarchy
Defaults to:
Ext.emptyFn
e : Ext.event.Event
event : Ext.event.Event
The underlying DOM event.
target : HTMLElement
The element gaining focus.
: HTMLElement
The element losing focus.
toComponent : Ext.Component
The Component gaining focus.
fromComponent : Ext.Component
The Component losing focus.
This method is called the first time a component is inserted into the DOM. If this
component Ext.Container other components, the onRender method
for child components is called after the parent's onRender.
Implementations of this method should avoid modifying the DOM but are free to read from and measure elements as needed. To adjust the DOM, consider implementing afterRender instead.
If this method is overridden, be sure to use callParent to call the base class
version.
onRender: function () {
this.callParent();
// custom actions
}
This method is not generally needed because components always have their own DOM element and these are maintained by config property updaters prior to insertion in the DOM. In general, it is always best to interrogate the component's elements outside the DOM where there is no associated reflow or layout cost. This method is useful for situations where the component's elements must be in the DOM. For example to be measured correctly.
Defaults to:
Ext.emptyFn
Available since: 6.5.0
The rendered flag is set when a widget is inserted into the document for the first time.
Note that this is a one-way operation. The first time a widget is inserted into the document, this flag is set, and it is never unset.
Get the reference to the current class from which this object was instantiated. Unlike Ext.Base#statics,
this.self is scope-dependent and it's meant to be used for dynamic inheritance. See Ext.Base#statics
for a detailed comparison
Ext.define('My.Cat', {
statics: {
speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
},
constructor: function() {
alert(this.self.speciesName); // dependent on 'this'
},
clone: function() {
return new this.self();
}
});
Ext.define('My.SnowLeopard', {
extend: 'My.Cat',
statics: {
speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
}
});
var cat = new My.Cat(); // alerts 'Cat'
var snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'
var clone = snowLeopard.clone();
alert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'
Defaults to:
Base
The CSS class to add to this component when it has a shadow.
Defaults to:
Ext.baseCSSPrefix + 'shadow'
The CSS class to add to this component's shim element if enabled.
Defaults to:
"x-shim"
An array of child elements to use as the children of the main element in the element template. Only used if "children" are not specified explicitly in the element template.
Defaults to:
[]
The name of the reference element to use as the "anchor" for the tool zones. The start zone is inserted just prior to the anchor element and the tail and end zones are inserted immediately after.
Not applicable for Ext.Container instances as they use docked items to create the tool zones
Defaults to:
'bodyElement'
A map that tracks all reference elements configured with a uiCls.
Contains the element reference by default since the element always gets
non-suffixed ui-specific CSS class names added to it (see syncUiCls)
Regular expression used for validating reference values.
Defaults to:
/^[a-z_][a-z0-9_]*$/i
Adds declarative listeners as nested arrays of listener objects.

The type of the plugin.
The plugin that was created.
Adds one or more Components to this Container. Example:
var myPanel = Ext.create({
xtype: 'panel',
html : 'This will be added to a Container'
});
var items = myContainer.add([myPanel]); // Array returned
var item = myContainer.add(myPanel); // One item is returned
newItems : Object/Object[]/Ext.Component/Ext.Component[]
The new item(s) to add to the Container. Note that if an array of items to add was passed in, an array of added items will be returned as well even if there was only one item.
The Component(s) that were added.
Ensures that the given property (if it is a Config System config) has a proper "updater" method on this instance to sync changes to the config.
Available since: 5.0.0
property : String

Adds a CSS class (or classes) to this Component's rendered element.
cls : String/String[]
The CSS class(es) to add.
prefix : String (optional)
Optional prefix to add to each class.
Defaults to: ""
suffix : String (optional)
Optional suffix to add to each class.
Defaults to: ""
Adds a listeners with the "delegate" event option. Users should not invoke this method directly. Use the "delegate" event option of addListener instead.
eventName : Object
fn : Object
scope : Object
options : Object
order : Object
caller : Object
manager : Object
This method applies a versioned, deprecation declaration to this class. This
is typically called by the deprecated config.
deprecations : Object
Adds an element reference to this Widget instance.
name : String
The name of the reference
domNode : HTMLElement
Reduces instantiation time for a Widget by lazily instantiating Ext.Element references the first time they are used. This optimization only works for elements with no listeners specified.
name : String
The name of the reference
domNode : HTMLElement
The on method is shorthand for addListener.
Appends an event handler to this object. For example:
myGridPanel.on("itemclick", this.onItemClick, this);
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:
myGridPanel.on({
cellclick: this.onCellClick,
select: this.onSelect,
viewready: this.onViewReady,
scope: this // Important. Ensure "this" is correct during handler execution
});
One can also specify options for each event handler separately:
myGridPanel.on({
cellclick: {fn: this.onCellClick, scope: this, single: true},
viewready: {fn: panel.onViewReady, scope: panel}
});
Names of methods in a specified scope may also be used:
myGridPanel.on({
cellclick: {fn: 'onCellClick', scope: this, single: true},
viewready: {fn: 'onViewReady', scope: panel}
});
eventName : String/Object
The name of the event to listen for. May also be an object who's property names are event names.
fn : Function/String (optional)
The method the event invokes or the name of
the method within the specified scope. Will be called with arguments
given to Ext.util.Observable#fireEvent plus the options parameter described
below.
scope : Object (optional)
The scope (this reference) in which the handler function is
executed. If omitted, defaults to the object which fired the event.
options : Object (optional)
An object containing handler configuration.
Note: The options object will also be passed as the last argument to every event handler.
This object may contain any of the following properties:
scope : Object
The scope (this reference) in which the handler function is executed. If omitted,
defaults to the object which fired the event.
delay : Number
The number of milliseconds to delay the invocation of the handler after the event fires.
single : Boolean
True to add a handler to handle just the next firing of the event, and then remove itself.
buffer : Number
Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.
onFrame : Number
Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.
target : Ext.util.Observable
Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.
element : String
This option is only valid for listeners bound to Ext.Component. The name of a Component property which references an Ext.dom.Element to add a listener to.
This option is useful during Component construction to add DOM event listeners to elements of Ext.Component which will exist only after the Component is rendered.
For example, to add a click listener to a Panel's body:
var panel = new Ext.panel.Panel({
title: 'The title',
listeners: {
click: this.handlePanelClick,
element: 'body'
}
});
In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.
panel.body.un(...)
delegate : String (optional)
A simple selector to filter the event target or look for a descendant of the target.
The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).
See the delegate example below.
capture : Boolean (optional)
When set to true, the listener is fired in the capture phase of the event propagation
sequence, instead of the default bubble phase.
The capture option is only available on Ext.dom.Element instances (or
when attaching a listener to a Ext.dom.Element via a Component using the
element option).
stopPropagation : Boolean (optional)
This option is only valid for listeners bound to Ext.dom.Element.
true to call stopPropagation on the event object
before firing the handler.
preventDefault : Boolean (optional)
This option is only valid for listeners bound to Ext.dom.Element.
true to call preventDefault on the event object
before firing the handler.
stopEvent : Boolean (optional)
This option is only valid for listeners bound to Ext.dom.Element.
true to call stopEvent on the event object
before firing the handler.
args : Array (optional)
Optional set of arguments to pass to the handler function before the actual
fired event arguments. For example, if args is set to ['foo', 42],
the event handler function will be called with an arguments list like this:
handler('foo', 42, <actual event arguments>...);
destroyable : Boolean (optional)
When specified as true, the function returns a destroyable object. An object
which implements the destroy method which removes all listeners added in this call.
This syntax can be a helpful shortcut to using un; particularly when
removing multiple listeners. NOTE - not compatible when using the element
option. See un for the proper syntax for removing listeners added using the
element config.
Defaults to:
false
priority : Number (optional)
An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.
order : String (optional)
A legacy option that is provided for backward compatibility.
It is recommended to use the priority option instead. Available options are:
'before': equal to a priority of 100'current': equal to a priority of 0 or default priority'after': equal to a priority of -100Defaults to:
'current'
order : String (optional)
A shortcut for the order event option. Provided for backward compatibility.
Please use the priority event option instead.
Combining Options
Using the options argument, it is possible to combine different types of listeners:
A delayed, one-time listener.
myPanel.on('hide', this.handleClick, this, {
single: true,
delay: 100
});
Attaching multiple handlers in 1 call
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers and handler configs.
grid.on({
itemclick: 'onItemClick',
itemcontextmenu: grid.onItemContextmenu,
destroy: {
fn: function () {
// function called within the 'altCmp' scope instead of grid
},
scope: altCmp // unique scope for the destroy handler
},
scope: grid // default scope - provided for example clarity
});
Delegate
This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example:
var panel = Ext.create({
xtype: 'panel',
renderTo: document.body,
title: 'Delegate Handler Example',
frame: true,
height: 220,
width: 220,
html: '<h1 class="myTitle">BODY TITLE</h1>Body content'
});
// The click handler will only be called when the click occurs on the
// delegate: h1.myTitle ("h1" tag with class "myTitle")
panel.on({
click: function (e) {
console.log(e.getTarget().innerHTML);
},
element: 'body',
delegate: 'h1.myTitle'
});
Defaults to: 'current'
Only when the destroyable option is specified.
A Destroyable object. An object which implements the destroy method which removes
all listeners added in this call. For example:
this.btnListeners = = myButton.on({
destroyable: true
mouseover: function() { console.log('mouseover'); },
mouseout: function() { console.log('mouseout'); },
click: function() { console.log('click'); }
});
And when those listeners need to be removed:
Ext.destroy(this.btnListeners);
or
this.btnListeners.destroy();
The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.
Example:
Ext.define('Foo', {
extend: 'Ext.Component',
initComponent: function () {
this.addManagedListener(MyApp.SomeGlobalSharedMenu, 'show', this.doSomething);
this.callParent();
}
});
As you can see, when an instance of Foo is destroyed, it ensures that the 'show'
listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.
As of version 5.1 it is no longer necessary to use this method in most cases because
listeners are automatically managed if the scope object provided to
addListener is an Observable instance.
However, if the observable instance and scope are not the same object you
still need to use mon or addManagedListener if you want the listener to be
managed.
item : Ext.util.Observable/Ext.dom.Element
The item to which to add a listener/listeners.
ename : Object/String
The event name, or an object containing event name properties.
fn : Function/String (optional)
If the ename parameter was an event
name, this is the handler function or the name of a method on the specified
scope.
scope : Object (optional)
If the ename parameter was an event name, this is the scope (this reference)
in which the handler function is executed.
options : Object (optional)
If the ename parameter was an event name, this is the
addListener options.
Only when the destroyable option is specified.
A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:
this.btnListeners = myButton.mon({
destroyable: true
mouseover: function() { console.log('mouseover'); },
mouseout: function() { console.log('mouseout'); },
click: function() { console.log('click'); }
});
And when those listeners need to be removed:
Ext.destroy(this.btnListeners);
or
this.btnListeners.destroy();
Adds a plugin. For example:
list.addPlugin('pullrefresh');
Or:
list.addPlugin({
type: 'pullrefresh',
pullRefreshText: 'Pull to refresh...'
});

plugin : Object/String/Ext.plugin.Abstract
The plugin or config object or alias to add.
This method is called after the component is initially added to the DOM. If this
component Ext.Container other components, the afterRender method
for child components is called before the parent's afterRender.
Implementations of this method should avoid reading from the DOM but are free to write to the DOM as needed. To read the DOM, consider implementing onRender instead.
This method is not generally needed because components always have their own DOM element and these are maintained by config property updaters prior to insertion in the DOM. In general, it is always best to manipulate the component's elements outside the DOM where there is no associated reflow or layout cost. This method is useful for situations where the component's elements must be in the DOM in order to be manipulated correctly.
Available since: 6.5.0
This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

Call the original method that was previously overridden with Ext.Base#override
Ext.define('My.Cat', {
constructor: function() {
alert("I'm a cat!");
}
});
My.Cat.override({
constructor: function() {
alert("I'm going to be a cat!");
this.callOverridden();

// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
args : Array/Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callOverridden(arguments)
Returns the result of calling the overridden method
Deprecated since version 4.1.0
Use method-callParent instead.
Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext#define).
Ext.define('My.Base', {
constructor: function (x) {
this.x = x;
},
statics: {
method: function (x) {
return x;
}
}
});
Ext.define('My.Derived', {
extend: 'My.Base',
constructor: function () {
this.callParent([21]);
}
});
var obj = new My.Derived();
alert(obj.x); // alerts 21
This can be used with an override as follows:
Ext.define('My.DerivedOverride', {
override: 'My.Derived',
constructor: function (x) {
this.callParent([x*2]); // calls original My.Derived constructor
}
});
var obj = new My.Derived();
alert(obj.x); // now alerts 42
This also works with static and private methods.
Ext.define('My.Derived2', {
extend: 'My.Base',
// privates: {
statics: {
method: function (x) {
return this.callParent([x*2]); // calls My.Base.method
}
}
});
alert(My.Base.method(10)); // alerts 10
alert(My.Derived2.method(10)); // alerts 20
Lastly, it also works with overridden static methods.
Ext.define('My.Derived2Override', {
override: 'My.Derived2',
// privates: {
statics: {
method: function (x) {
return this.callParent([x*2]); // calls My.Derived2.method
}
}
});
alert(My.Derived2.method(10); // now alerts 40
To override a method and replace it and also call the superclass method, use method-callSuper. This is often done to patch a method to fix a bug.
args : Array/Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callParent(arguments)
Returns the result of calling the parent method
This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.
Consider:
Ext.define('Ext.some.Class', {
method: function () {
console.log('Good');
}
});
Ext.define('Ext.some.DerivedClass', {
extend: 'Ext.some.Class',
method: function () {
console.log('Bad');
// ... logic but with a bug ...
this.callParent();
}
});
To patch the bug in Ext.some.DerivedClass.method, the typical solution is to create an
override:
Ext.define('App.patches.DerivedClass', {
override: 'Ext.some.DerivedClass',
method: function () {
console.log('Fixed');
// ... logic but with bug fixed ...
this.callSuper();
}
});
The patch method cannot use method-callParent to call the superclass
method since that would call the overridden method containing the bug. In
other words, the above patch would only produce "Fixed" then "Good" in the
console log, whereas, using callParent would produce "Fixed" then "Bad"
then "Good".
args : Array/Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callSuper(arguments)
Returns the result of calling the superclass method
Center this cfg-floated or positioned Component in its parent.

Retrieves the first direct child of this container which matches the passed selector or component. The passed in selector must comply with an Ext.ComponentQuery selector, or it can be an actual Ext.Component.
selector : String/Ext.Component (optional)
An Ext.ComponentQuery selector. If no selector is specified, the first child will be returned.
The matching child Ext.Component (or null if no match was found).
Clears all listeners that were attached using the "delegate" event option. Users should not invoke this method directly. It is called automatically as part of normal clearListeners processing.
Creates new Component.
config : Object
The standard configuration object.
Converts the provided type or config object into a plugin instance.
config : String/Object/Ext.plugin.Abstract
The plugin type, config object or instance.
Creates an event handling function which re-fires the event from this object as the passed event name.
newName : String
The name under which to re-fire the passed parameters.
beginEnd : Array (optional)
The caller can specify on which indices to slice.
Destroys the Widget. This method should not be overridden in custom Widgets, because it sets the flags and does final cleanup that must go last. Instead, override doDestroy method to add functionality at destruction time.
Destroys member properties by name.
If a property name is the name of a config, the getter is not invoked, so if the config has not been initialized, nothing will be done.
The property will be destroyed, and the corrected name (if the property is a config
and config names are prefixed) will set to null in this object's dictionary.
args : String...
One or more names of the properties to destroy and remove from the object.
Removes and destroys a plugin.
Note: Not all plugins are designed to be removable. Consult the documentation for the specific plugin in question to be sure.
Available since: 6.2.0

The plugin or its id to remove.
plugin instance or null if not found.
name : Object
fn : Object
scope : Object
options : Object
order : Object
caller : Object
manager : Object
Perform the actual destruction sequence. This is the method to override in your subclasses to add steps specific to the destruction of custom Component.
If the Component is currently added to a Container it will first be removed from that Container. All Ext.Element references are also deleted and the Component is de-registered from Ext.ComponentManager.
As a rule of thumb, subclasses should destroy their child Components, Elements, and/or other objects before calling parent method. Any object references will be nulled after this method has finished, to prevent the possibility of memory leaks.
Available since: 6.2.0
Fires a delegated event. Users should not invoke this method directly. It is called automatically by the framework as needed (see the "delegate" event option of addListener for more details.

Retrieves the first descendant of this container which matches the passed selector. The passed in selector must comply with an Ext.ComponentQuery selector, or it can be an actual Ext.Component.
selector : String/Ext.Component (optional)
An Ext.ComponentQuery selector or Ext.Component. If no selector is specified, the first child will be returned.
The matching descendant Ext.Component (or null if no match was found).
Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if
present. There is no implementation in the Observable base class.
This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component#getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.
Example:
Ext.define('Ext.overrides.form.field.Base', {
override: 'Ext.form.field.Base',
// Add functionality to Field's initComponent to enable the change event to bubble
initComponent: function () {
this.callParent();
this.enableBubble('change');
}
});
var myForm = Ext.create('Ext.form.Panel', {
title: 'User Details',
items: [{
...
}],
listeners: {
change: function() {
// Title goes red if form has been modified.
myForm.header.setStyle('color', 'red');
}
}
});
eventNames : String/String[]
The event name to bubble, or an Array of event names.
Called when an item is added to this container either during initialization of the cfg-items config, or when new items are added), or {@link #method-insert inserted.
If the passed object is not an instanced component, it converts the passed object into an instanced child component.
It applies cfg-defaults applied for contained child items - that is items which are not positiond using left, top, bottom, right, centered or docked.
Derived classes can override this method to process context appropriate short-hands such as Ext.Toolbar and "->" to insert a spacer.
item : Mixed
The item being added. May be a raw config object or an instanced Component or some other short-hand understood by the container.
The component to be added.
The method finds this floated component's floatParent. That means a DOM positioning container which acts as a root element for sibling floated components, and allows allows floated components to be absolutely positioned, and their encapsulating elements to be reordered to produce a visual stacking effect.
This component's element is appended to its floatParent.
There is a global floatParent element, created on demand when the first top level floated component
is shown. This may be an item child of a container configured with cfg-floated: true,
or a free floated component which is programatically shown.
Child items of components inside a floated component may also be configured floated. These
are give a floatParent which is created on demand wrapping the nearest floated ancestor.
This means that when that ancestor's element is brought to the top of the stack (by moving its
element to the end of its own floatParent), the descendant elements will automatically remain above.
Finds an alternate Component to focus if this Component is disabled while focused, or focused while disabled, or otherwise unable to focus.
In both cases, focus must not be lost to document.body, but must move to an intuitively connectible Component, either a sibling, or uncle or nephew.
This is both for the convenience of keyboard users, and also for when focus is tracked within a Component tree such as for ComboBoxes and their dropdowns.
For example, a ComboBox with a PagingToolbar in is BoundList. If the "Next Page" button is hit, the LoadMask shows and focuses, the next page is the last page, so the "Next Page" button is disabled. When the LoadMask hides, it attempt to focus the last focused Component which is the disabled "Next Page" button. In this situation, focus should move to a sibling within the PagingToolbar.
A closely related focusable Component to which focus can move.
Retrieves plugin by its type alias. For example:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: ['listpaging', 'pullrefresh']
});
list.findPlugin('pullrefresh').setPullRefreshText('Pull to refresh...');
Note: See also getPlugin.
Available since: 6.2.0
type : String
The Plugin's type as specified by the class's
alias configuration.
plugin instance or null if not found.
Fires the specified event with the passed parameters and executes a function (action).
By default, the action function will be executed after any "before" event handlers
(as specified using the order option of
addListener), but before any other
handlers are fired. This gives the "before" handlers an opportunity to
cancel the event by returning false, and prevent the action function from
being called.
The action can also be configured to run after normal handlers, but before any "after"
handlers (as specified using the order event option) by passing 'after'
as the order parameter. This configuration gives any event handlers except
for "after" handlers the opportunity to cancel the event and prevent the action
function from being called.
eventName : String
The name of the event to fire.
args : Array
Arguments to pass to handlers and to the action function.
fn : Function
The action function.
scope : Object (optional)
The scope (this reference) in which the handler function is
executed. If omitted, defaults to the object which fired the event.
options : Object (optional)
Event options for the action function. Accepts any
of the options of addListener
order : String (optional)
The order to call the action function relative
too the event handlers ('before' or 'after'). Note that this option is
simply used to sort the action function relative to the event handlers by "priority".
An order of 'before' is equivalent to a priority of 99.5, while an order of
'after' is equivalent to a priority of -99.5. See the priority option
of addListener for more details.
Defaults to: 'before'
Deprecated since version 5.5
Use fireEventedAction instead.
Fires the specified event with the passed parameters (minus the event name, plus the options object passed
to addListener).
An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.

returns false if any of the handlers return false otherwise it returns true.
Fires the specified event with the passed parameters and executes a function (action). Evented Actions will automatically dispatch a 'before' event passing. This event will be given a special controller that allows for pausing/resuming of the event flow.
By pausing the controller the updater and events will not run until resumed. Pausing, however, will not stop the processing of any other before events.
eventName : String
The name of the event to fire.
args : Array
Arguments to pass to handlers and to the action function.
fn : Function/String
The action function.
scope : Object (optional)
The scope (this reference) in which the handler function is
executed. If omitted, defaults to the object which fired the event.
fnArgs : Array/Boolean (optional)
Optional arguments for the action fn. If not
given, the normal args will be used to call fn. If false is passed, the
args are used but if the first argument is this instance it will be removed
from the args passed to the action function.
Try to focus this component.
If this component is disabled or otherwise not focusable, a close relation will be targeted for focus instead to keep focus localized for keyboard users.
selectText : Boolean/Number[] (optional)
If applicable, true to also select all the text
in this component, or an array consisting of start and end (defaults to start)
position of selection.
true if focus target was found and focusing was attempted,

in getDockedItems.
component : String/Number
The id or index of the component to find.
The docked component, if found.
Returns all the Ext.Component#docked items in this container.
The docked items of this container.
A template method for modifying the element config before it is processed.
By default adds the result of this.getTemplate() as the children array of
element if children were not specified in the original
element config. Typically this method should not need to be implemented
in subclasses. Instead the element property should be use to configure
the element template for a given Widget subclass.
This method is called once when the first instance of each Widget subclass is created. The element config object that is returned is cached and used as the template for all successive instances. The scope object for this method is the class prototype, not the instance.
the element config object
This method is in place on the instance during construction to ensure that any lookup or getReferences calls have the items initialized prior to the lookup.
For cfg-floated components only.
Finds the owning cfg-floated component (if any) responsible for the base z-index stack position of this compoonent, and, if that component is cfg-relative, for the coordinate system in which this component is positioned.
If this is a top level floated component, this method will return null

Returns the focus holder element associated with this Container. By default, this is the Container's focusEl element; however if defaultFocus is defined, the child component referenced by that property will be found and returned instead.
the focus holding element.
This method returns an object containing the inherited properties for this instance.
Available since: 5.0.0
inner : Boolean (optional)
Pass true to return inheritedStateInner instead
of the normal inheritedState object. This is only needed internally and should
not be passed by user code.
Defaults to: false
The inheritedState object containing inherited properties.
This method returns the value of a config property that may be inherited from some ancestor.
In some cases, a config may be explicitly set on a component with the intent of
only being presented to its children while that component should act upon the
inherited value (see referenceHolder for example). In these cases the skipThis
parameter should be specified as true.
Available since: 5.0.0
property : String
The name of the config property to return.
skipThis : Boolean (optional)
Pass true if the property should be ignored if
found on this instance. In other words, true means the property must be inherited
and not explicitly set on this instance.
Defaults to: false

Returns the initial configuration passed to the constructor when instantiating this class.
Given this example Ext.button.Button definition and instance:
Ext.define('MyApp.view.Button', {
extend: 'Ext.button.Button',
xtype: 'mybutton',
scale: 'large',
enableToggle: true
});
var btn = Ext.create({
xtype: 'mybutton',
renderTo: Ext.getBody(),
text: 'Test Button'
});
Calling btn.getInitialConfig() would return an object including the config
options passed to the create method:
xtype: 'mybutton',
renderTo: // The document body itself
text: 'Test Button'
Calling btn.getInitialConfig('text')returns 'Test Button'.
name : String (optional)
Name of the config option to return.
The full config object or a single config value
when name parameter specified.
Returns all inner items of this container. inner means that the item is not docked or
positioned.

In IE11 vertically flexed elements (such as container body-el or panel body-wrap-el) are not flexed properly when the container has a max-height, but no height. We can workaround the issue by wrapping the vertical box in a horizontal box. See EXTJS-24498
Returns an object holding the descendants of this container keyed by their
name. This object should not be held past the scope of the function calling this
method. It will not be valid if items are added or removed from this or any
sub-container.
The intended usage is shown here (assume there are 3 components with names of "foo", "bar" and "baz" at some level below this container):
onClick: function () {
var items = this.getNamedItems();
// using "items" we can access any descendant by its "name"
items.foo.getValue() + items.bar.getValue() + items.baz.getValue();
}
If this component has a name assigned to it, it is not included in this
object. That name is understood to belong to the ancestor container configured
as the nameHolder.
Available since: 6.5.0
An object with each named child. This will be null if this
container has no descendants with a name specified.
Returns the parent of this component, if it has one.

Similar to getRenderTarget but for positioned items.
Available since: 6.5.0
item : Ext.Component
The positioned item being added.
Used by ComponentQuery to retrieve all of the items
which can potentially be considered a child of this Container.
This should be overridden by components which have child items
that are not contained in items. For example dockedItems, menu, etc
deep : Object
Used by Ext.ComponentQuery, and the up method to find the owning Component in the linkage hierarchy.
By default this returns the Container which contains this Component.
This may be overridden by Component authors who implement ownership hierarchies which are not based upon ownerCt, such as BoundLists being owned by Fields or Menus being owned by Buttons.
Returns an object holding the descendants of this view keyed by their
reference. This object should not be held
past the scope of the function calling this method. It will not be valid if items
are added or removed from this or any sub-container.
The intended usage is shown here (assume there are 3 components with reference values of "foo", "bar" and "baz" at some level below this container):
onClick: function () {
var refs = this.getReferences();
// using "refs" we can access any descendant by its "reference"
refs.foo.getValue() + refs.bar.getValue() + refs.baz.getValue();
}
If this component has a reference assigned
to it, that is not included in this object. That reference is understood to
belong to the ancestor container configured as the referenceHolder.
Available since: 5.0.0
An object with each child reference. This will be null if this
container has no descendants with a reference
specified.
Returns the element into which the html content and items should be rendered.
This defaults to the bodyElement but derived classes can override this method
to use a different element.
For containers his only applies to inner items, not docked items. The
positioned items are rendered to the element returned by the
{@link Ext.Container#getPositionedItemTarget method.
Available since: 6.5.0
Returns the element that the "rootCls" (x-root) should be applied to.
Should always return the component's main element.
Overridden by Ext.viewport.Default to return the page body element
This method is required by the Scroller to return the scrollable client region
The scrolling viewport region.
Returns the parameter to sort upon when sorting this header. By default this returns the dataIndex and will not need to be overridden in most cases.
Returns all visible leaf columns.
selector : Object
Returns the index of this column in the list of visible columns only if this column is a base level Column. If it
is a group column, it returns false.
Returns this Component's xtype hierarchy as a slash-delimited string. For a list of all available xtypes, see the Ext.Component header.
Note: If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.
Example usage:
var t = new Ext.field.Text();
alert(t.getXTypes()); // alerts 'component/field/textfield'
The xtype hierarchy string.
Checks if the specified CSS class exists on this element's DOM node.
className : String
The CSS class to check for.
true if the class exists, else false.
Checks to see if this object has any listeners for a specified event, or whether the event bubbles. The answer indicates whether the event needs firing or not.

true if the event is being listened for or bubbles, else false
Returns true if this component has a parent.
true if this component has a parent.
Hides this Component optionally using an animation.
animation : Object/Boolean (optional)
You can specify an animation here or a bool to use the hideAnimation config.

draggable : Ext.drag.Source
This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.
Initializes the Element for this Widget instance. If this is the first time a Widget of this type has been instantiated the element config will be processed to create an Element. This Element is then cached on the prototype (see afterCachedConfig) so that future instances can obtain their element by simply cloning the Element that was cached by the first instance.
Called for the first instance of this Widget to create an object that contains the listener configs for all of the element references keyed by reference name. The object is cached on the prototype and has the following shape:
_elementListeners: {
element: {

The returned object is prototype chained to the _elementListeners object of its superclass, and each key in the object is prototype chained to object with the corresponding key in the superclass _elementListeners. This allows element listeners to be inherited and overridden when subclassing widgets.
This method is invoked with the prototype object as the scope
elementConfig : Object
Sets up the focus listener on this Component's focusEl if it has one.
Form Components which must implicitly participate in tabbing order usually have a naturally
focusable element as their focusEl, and it is the DOM event of that
receiving focus which drives the Component's onFocus handling, and the DOM event of it
being blurred which drives the onBlur handling.
force : Object
Template method to do any event listener initialization for a Focusable. This generally happens after the focusEl is available.
force : Object
Called by getInherited to initialize the inheritedState the first time it is requested.
inheritedState : Object
This method should be called when the instance is ready to start listening for
keyboard events. This is called automatically for Ext.Component and derived
classes. This is done after the component is rendered.
Initializes a "uiReference". Ui rerefences are reference elements that have classCls and ui info in their CSS class names. They can be used by setting uiCls in the template, or by invoking this method to setup the ui reference after element/template initialization (Toolable uses this for its dock wrapper)
referenceName : String
uiCls : String
isInstance : Boolean (optional)
pass false if this is not an instance-level
reference
Defaults to: false
Allows addition of behavior to the rendering phase.
This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.
Adds a child Component at the given index. For example, here's how we can add a new item, making it the first child Component of this Container:
myContainer.insert(0, {xtype: 'panel', html: 'new item'});
index : Number
The index to insert the Component at.
item : Object
The Component to insert.
This method marks the current inherited state as invalid. The next time a call is
made to getInherited the objects will be recreated and initialized.
Available since: 5.0.0
Tests whether this Widget matches a Ext.ComponentQuery selector string.
selector : String
The selector string to test against.

is being destroyed.
Returns true if this Component is currently disabled.
true if currently disabled.
Returns true if this Component is not currently disabled.
true if not currently disabled.
Determine if this Focusable can receive focus at this time.
Note that Containers can be non-focusable themselves while delegating focus treatment to a child Component; see Ext.Container for more information.
deep : Boolean (optional)
Optionally determine if the container itself is focusable, or if container's focus is delegated to a child component and that child is focusable.
Defaults to: false
True if component is focusable, false if not.
Returns true if this Component is currently hidden.
deep : Boolean/Ext.Widget (optional)
true to check if this component
is hidden because a parent container is hidden. Alternatively, a reference to the
top-most parent at which to stop climbing.
Defaults to: false

Returns true if this Component is currently visible.
A Widget is visible if its element is not hidden, and has been rendered and has not been destroyed.
deep : Boolean (optional)
true to check if this component
is visible and all parents are also visible.
Contrast this with the isHidden method which just checks the hidden state of the component.
Defaults to: false
true if currently visible.
Tests whether or not this Component is of a specific xtype. This can test whether this Component is descended
from the xtype (default) or whether it is directly of the xtype specified (shallow = true).
**If using your own subclasses, be aware that a Component must register its own xtype
to participate in determination of inherited xtypes.__
For a list of all available xtypes, see the Ext.Component header.
Example usage:
var t = new Ext.field.Text();
var isText = t.isXType('textfield'); // true
var isBoxSubclass = t.isXType('field'); // true, descended from Ext.field.Field
var isBoxInstance = t.isXType('field', true); // false, not a direct Ext.field.Field instance
xtype : String
The xtype to check for this Component.
shallow : Boolean (optional)
false to check whether this Component is descended from the xtype (this is
the default), or true to check whether this Component is directly of the specified xtype.
true if this component descends from the specified xtype, false otherwise.

defaults to true because it is possible that a reference property set by the
owner of a component that is also a referenceHolder itself. In this case, the
reference connects not to this component but to the parent referenceHolder.
Defaults to: true
The reference holder.
Returns the Ext.data.Session for this instance. This property may come
from this instance's session or be inherited from this object's parent.

to ensure two-way bindings (via bind) as well as any publishes are updated.
This method is cached on the cfg instance for re-use.
Available since: 5.0.0
cfg : Ext.Config
The updater function.
Convenience method which calls setMasked with a value of true (to show the mask). For additional
functionality, call the setMasked function direction (See the masked configuration documentation
for more information).
mask : Object
Shorthand for addManagedListener. The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.
Example:
Ext.define('Foo', {
extend: 'Ext.Component',
initComponent: function () {
this.addManagedListener(MyApp.SomeGlobalSharedMenu, 'show', this.doSomething);
this.callParent();
}
});
As you can see, when an instance of Foo is destroyed, it ensures that the 'show'
listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.
As of version 5.1 it is no longer necessary to use this method in most cases because
listeners are automatically managed if the scope object provided to
addListener is an Observable instance.
However, if the observable instance and scope are not the same object you
still need to use mon or addManagedListener if you want the listener to be
managed.
item : Ext.util.Observable/Ext.dom.Element
The item to which to add a listener/listeners.
ename : Object/String
The event name, or an object containing event name properties.
fn : Function/String (optional)
If the ename parameter was an event
name, this is the handler function or the name of a method on the specified
scope.
scope : Object (optional)
If the ename parameter was an event name, this is the scope (this reference)
in which the handler function is executed.
options : Object (optional)
If the ename parameter was an event name, this is the
addListener options.
Only when the destroyable option is specified.
A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:
this.btnListeners = myButton.mon({
destroyable: true
mouseover: function() { console.log('mouseover'); },
mouseout: function() { console.log('mouseout'); },
click: function() { console.log('click'); }
});
And when those listeners need to be removed:
Ext.destroy(this.btnListeners);
or
this.btnListeners.destroy();
Shorthand for removeManagedListener. Removes listeners that were added by the mon method.
item : Ext.util.Observable/Ext.dom.Element
The item from which to remove a listener/listeners.
ename : Object/String
The event name, or an object containing event name properties.
fn : Function (optional)
If the ename parameter was an event name, this is the handler function.
scope : Object (optional)
If the ename parameter was an event name, this is the scope (this reference)
in which the handler function is executed.
Returns the next node in the Component tree in tree traversal order.
Note that this is not limited to siblings, and if invoked upon a node with no matching siblings, will walk the tree to attempt to find a match. Contrast with nextSibling.
selector : String (optional)
A Ext.ComponentQuery selector to filter the following nodes.
The next node (or the next node which matches the selector).
Returns null if there is no matching node.
Returns the next sibling of this Component.
Optionally selects the next sibling which matches the passed Ext.ComponentQuery selector.
May also be referred to as next()
Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with
nextNode
selector : String (optional)
A Ext.ComponentQuery selector to filter the following items.
The next sibling (or the next sibling which matches the selector).
Returns null if there is no matching sibling.
The on method is shorthand for addListener.
Appends an event handler to this object. For example:
myGridPanel.on("itemclick", this.onItemClick, this);
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:
myGridPanel.on({
cellclick: this.onCellClick,
select: this.onSelect,
viewready: this.onViewReady,
scope: this // Important. Ensure "this" is correct during handler execution
});
One can also specify options for each event handler separately:
myGridPanel.on({
cellclick: {fn: this.onCellClick, scope: this, single: true},
viewready: {fn: panel.onViewReady, scope: panel}
});
Names of methods in a specified scope may also be used:
myGridPanel.on({
cellclick: {fn: 'onCellClick', scope: this, single: true},
viewready: {fn: 'onViewReady', scope: panel}
});
eventName : String/Object
The name of the event to listen for. May also be an object who's property names are event names.
fn : Function/String (optional)
The method the event invokes or the name of
the method within the specified scope. Will be called with arguments
given to Ext.util.Observable#fireEvent plus the options parameter described
below.
scope : Object (optional)
The scope (this reference) in which the handler function is
executed. If omitted, defaults to the object which fired the event.
options : Object (optional)
An object containing handler configuration.
Note: The options object will also be passed as the last argument to every event handler.
This object may contain any of the following properties:
scope : Object
The scope (this reference) in which the handler function is executed. If omitted,
defaults to the object which fired the event.
delay : Number
The number of milliseconds to delay the invocation of the handler after the event fires.
single : Boolean
True to add a handler to handle just the next firing of the event, and then remove itself.
buffer : Number
Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.
onFrame : Number
Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.
target : Ext.util.Observable
Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.
element : String
This option is only valid for listeners bound to Ext.Component. The name of a Component property which references an Ext.dom.Element to add a listener to.
This option is useful during Component construction to add DOM event listeners to elements of Ext.Component which will exist only after the Component is rendered.
For example, to add a click listener to a Panel's body:
var panel = new Ext.panel.Panel({
title: 'The title',
listeners: {
click: this.handlePanelClick,
element: 'body'
}
});
In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.
panel.body.un(...)
delegate : String (optional)
A simple selector to filter the event target or look for a descendant of the target.
The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).
See the delegate example below.
capture : Boolean (optional)
When set to true, the listener is fired in the capture phase of the event propagation
sequence, instead of the default bubble phase.
The capture option is only available on Ext.dom.Element instances (or
when attaching a listener to a Ext.dom.Element via a Component using the
element option).
stopPropagation : Boolean (optional)
This option is only valid for listeners bound to Ext.dom.Element.
true to call stopPropagation on the event object
before firing the handler.
preventDefault : Boolean (optional)
This option is only valid for listeners bound to Ext.dom.Element.
true to call preventDefault on the event object
before firing the handler.
stopEvent : Boolean (optional)
This option is only valid for listeners bound to Ext.dom.Element.
true to call stopEvent on the event object
before firing the handler.
args : Array (optional)
Optional set of arguments to pass to the handler function before the actual
fired event arguments. For example, if args is set to ['foo', 42],
the event handler function will be called with an arguments list like this:
handler('foo', 42, <actual event arguments>...);
destroyable : Boolean (optional)
When specified as true, the function returns a destroyable object. An object
which implements the destroy method which removes all listeners added in this call.
This syntax can be a helpful shortcut to using un; particularly when
removing multiple listeners. NOTE - not compatible when using the element
option. See un for the proper syntax for removing listeners added using the
element config.
Defaults to:
false
priority : Number (optional)
An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.
order : String (optional)
A legacy option that is provided for backward compatibility.
It is recommended to use the priority option instead. Available options are:
'before': equal to a priority of 100'current': equal to a priority of 0 or default priority'after': equal to a priority of -100Defaults to:
'current'
order : String (optional)
A shortcut for the order event option. Provided for backward compatibility.
Please use the priority event option instead.
Combining Options
Using the options argument, it is possible to combine different types of listeners:
A delayed, one-time listener.
myPanel.on('hide', this.handleClick, this, {
single: true,
delay: 100
});
Attaching multiple handlers in 1 call
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers and handler configs.
grid.on({
itemclick: 'onItemClick',
itemcontextmenu: grid.onItemContextmenu,
destroy: {
fn: function () {
// function called within the 'altCmp' scope instead of grid
},
scope: altCmp // unique scope for the destroy handler
},
scope: grid // default scope - provided for example clarity
});
Delegate
This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example:
var panel = Ext.create({
xtype: 'panel',
renderTo: document.body,
title: 'Delegate Handler Example',
frame: true,
height: 220,
width: 220,
html: '<h1 class="myTitle">BODY TITLE</h1>Body content'
});
// The click handler will only be called when the click occurs on the
// delegate: h1.myTitle ("h1" tag with class "myTitle")
panel.on({
click: function (e) {
console.log(e.getTarget().innerHTML);
},
element: 'body',
delegate: 'h1.myTitle'
});
Defaults to: 'current'
Only when the destroyable option is specified.
A Destroyable object. An object which implements the destroy method which removes
all listeners added in this call. For example:
this.btnListeners = = myButton.on({
destroyable: true
mouseover: function() { console.log('mouseover'); },
mouseout: function() { console.log('mouseout'); },
click: function() { console.log('click'); }
});
And when those listeners need to be removed:
Ext.destroy(this.btnListeners);
or
this.btnListeners.destroy();

component : Object
alignment : Object
options : Object
Relays selected events from the specified Observable as if the events were fired by this.
For example if you are extending Grid, you might decide to forward some events from store. So you can do this inside your initComponent:
this.relayEvents(this.getStore(), ['load']);
The grid instance will then have an observable 'load' event which will be passed the parameters of the store's load event and any function fired with the grid's load event would have access to the grid using the this keyword (unless the event is handled by a controller's control/listen event listener in which case 'this' will be the controller rather than the grid).
origin : Object
The Observable whose events this object is to relay.
events : String[]/Object
Array of event names to relay or an Object with key/value pairs translating to ActualEventName/NewEventName respectively. For example: this.relayEvents(this, {add:'push', remove:'pop'});
Would now redispatch the add event of this as a push event and the remove event as a pop event.
prefix : String (optional)
A common prefix to prepend to the event names. For example:
this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.
A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:
this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
Can be undone by calling
Ext.destroy(this.storeRelayers);
or this.store.relayers.destroy();
Removes an item from this Container, optionally destroying it.
which : Ext.Component/String/Number/Array
The component instance, id or index to remove or an array of these.
destroy : Boolean (optional)
true to automatically call Component's
destroy method.
The Component that was removed.
Removes all items currently in the Container, optionally destroying them all.
destroy : Boolean
If true, destroys
each removed Component.
everything : Boolean
If true, completely remove all items including
docked / centered and positioned items.
Array of the removed Components
Removes the Component at the specified index:
myContainer.removeAt(0); // removes the first item
index : Number
The index of the Component to remove.
The removed Component
Removes the given CSS class(es) from this widget's primary element.
cls : String/String[]
The class(es) to remove.
prefix : String (optional)
Optional prefix to prepend before each class.
Defaults to: ""
suffix : String (optional)
Optional suffix to append to each class.
Defaults to: ""
Removes delegated listeners for a given eventName, function, and scope. Users should not invoke this method directly. It is called automatically by the framework as part of removeListener processing.
eventName : Object
fn : Object
scope : Object
Removes an inner Component at the specified index:
myContainer.removeInnerAt(0); // removes the first item of the innerItems property
index : Number
The index of the Component to remove.
The removed Component
Removes an event handler.
eventName : String
The type of event the handler was associated with.
fn : Function
The handler to remove. This must be a reference to the function passed into the addListener call.
scope : Object (optional)
The scope originally specified for the handler. It must be the same as the scope argument specified in the original call to Ext.util.Observable#addListener or the listener will not be removed.
Convenience Syntax
You can use the addListener
destroyable: true config option in place of calling un(). For example:
var listeners = cmp.on({
scope: cmp,
afterrender: cmp.onAfterrender,
beforehide: cmp.onBeforeHide,
destroyable: true
});
// Remove listeners
listeners.destroy();
// or
cmp.un(
scope: cmp,
afterrender: cmp.onAfterrender,
beforehide: cmp.onBeforeHide
);
Exception - DOM event handlers using the element config option
You must go directly through the element to detach an event handler attached using the addListener element option.
panel.on({
element: 'body',
click: 'onBodyCLick'

Shows this component by another component. If you specify no alignment, it will automatically position this component relative to the reference component.
For example, say we are aligning a Panel next to a Button, the alignment string would look like this:
[panel-vertical (t/b/c)][panel-horizontal (l/r/c)]-[button-vertical (t/b/c)][button-horizontal (l/r/c)]
where t = top, b = bottom, c = center, l = left, r = right.
tl-tr means top-left corner of the Panel to the top-right corner of the Buttontc-bc means top-center of the Panel to the bottom-center of the ButtonYou can put a '?' at the end of the alignment string to constrain the positioned element to the Ext.Viewport
// show `panel` by `button` using the default positioning (auto fit)
panel.showBy(button);
// align the top left corner of `panel` with the top right corner of `button` (constrained to viewport)
panel.showBy(button, "tl-tr?");
// align the bottom right corner of `panel` with the center left edge of `button` (not constrained by viewport)
panel.showBy(button, "br-cl");
component : Ext.Component
The target component to show this component by.
alignment : String (optional)

Get the reference to the class from which this object was instantiated. Note that unlike Ext.Base#self,
this.statics() is scope-independent and it always returns the class from which it was called, regardless of what
this points to during run-time
Ext.define('My.Cat', {
statics: {
totalCreated: 0,
speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
},
constructor: function() {
var statics = this.statics();
alert(statics.speciesName); // always equals to 'Cat' no matter what 'this' refers to
// equivalent to: My.Cat.speciesName
alert(this.self.speciesName); // dependent on 'this'
statics.totalCreated++;
},
clone: function() {
var cloned = new this.self(); // dependent on 'this'
cloned.groupName = this.statics().speciesName; // equivalent to: My.Cat.speciesName
return cloned;
}
});
Ext.define('My.SnowLeopard', {
extend: 'My.Cat',
statics: {
speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
},
constructor: function() {
this.callParent();
}
});
var cat = new My.Cat(); // alerts 'Cat', then alerts 'Cat'
var snowLeopard = new My.SnowLeopard(); // alerts 'Cat', then alerts 'Snow Leopard'
var clone = snowLeopard.clone();
alert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'
alert(clone.groupName); // alerts 'Cat'
alert(My.Cat.totalCreated); // alerts 3
Suspends firing of the named event(s).

scope : Object (optional)
The scope originally specified for the handler. It must be the same as the scope argument specified in the original call to Ext.util.Observable#addListener or the listener will not be removed.
Convenience Syntax
You can use the addListener
destroyable: true config option in place of calling un(). For example:
var listeners = cmp.on({
scope: cmp,
afterrender: cmp.onAfterrender,
beforehide: cmp.onBeforeHide,
destroyable: true
});
// Remove listeners
listeners.destroy();
// or
cmp.un(
scope: cmp,
afterrender: cmp.onAfterrender,
beforehide: cmp.onBeforeHide
);
Exception - DOM event handlers using the element config option
You must go directly through the element to detach an event handler attached using the addListener element option.
panel.on({
element: 'body',
click: 'onBodyCLick'
});
panel.body.un({

Override members of this class. Overridden methods can be invoked via Ext.Base#callParent.
Ext.define('My.Cat', {
constructor: function() {
alert("I'm a cat!");
}
});
My.Cat.override({
constructor: function() {
alert("I'm going to be a cat!");
this.callParent(arguments);
alert("Meeeeoooowwww");
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
Direct use of this method should be rare. Use Ext.define instead:
Ext.define('My.CatOverride', {
override: 'My.Cat',
constructor: function() {
alert("I'm going to be a cat!");
this.callParent(arguments);
alert("Meeeeoooowwww");
}
});
The above accomplishes the same result but can be managed by the Ext.Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class (My.Cat).

Note: This event is not available to be used with event delegation. Instead painted only fires if you explicitly
add at least one listener to it, for performance reasons.

Toolable components need special handling for their padding. When there are no tools (which usually means no dock wrapper) the padding on all sides is placed on the body-el, However, when the component has tools, the horizontal padding needs to be removed from the body-el and placed on the innermost dock wrapper so that the horizontal padding is between the outermost tools and the left/right edges of the component. In this configuration the space between the body and the tools is provided by the tools themselves via $tool-spacing.
The vertical padding remains on the body-el so that the height of the toolable component when auto-heighted is determined by the body-el's line-height + padding + the element borders. The tools gain an additional advantage from this arrangement because it means they can be taller than the component's line-height and not cause the component's height to increase since they are not "inside" of the vertical padding.
