The documentation for the ExtReact product diverges somewhat from the
documentation of other Sencha products. The sections below describe
documentation for all products except where indicated as unique to
ExtReact.
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.
ExtReact component classes list the configurable name prominently at the top of the API class doc followed by the fully-qualified class name.
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.
ExtReact component classes display
configuration options as props
ExtReact component classes do not list
properties as a dedicated member type, but rather as
read only props
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.
All ExtReact props are bindable
unless decorated as immutable
Immutable ExtReact props may not be use as a configurable prop when instantiating a component
classInstance.method1().method2().etc();false is returned from
an event handler- Indicates a framework class
- A singleton framework class. *See the singleton flag for more information
- A component-type framework class (any class within the Ext JS framework that extends Ext.Component)
- Indicates that the class, member, or guide is new in the currently viewed version
- Indicates a class member of type config
Or in the case of an ExtReact component class this
indicates a member of type prop
- Indicates a class member of type property
- Indicates a class member of type
method
- Indicates a class member of type event
- Indicates a class member of type
theme variable
- Indicates a class member of type
theme mixin
- Indicates that the class, member, or guide is new in the currently viewed version
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.
ExtReact component classes do not hoist the getter /
setter methods into the prop. All methods will be described in the
Methods section
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.

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 passed a string, it will be assumed to be a Ext.ComponentQuery selector. A number will reference an index or a <ext-component/> instance may be passed as well. An object config will be created as a new component.
Defaults to:
0
Returns the value of activeItem
<ext-component/> / Object / String / Number
Sets the value of activeItem
activeItem : <ext-component/> / Object / String / Number
The config for the all day field.
Defaults to:
{
xtype: 'checkboxfield',
itemId: 'allDay',
name: 'allDay',
label: 'All Day',
listeners: {
change: 'onAllDayChange'
}
}
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
Configure true to show an anchor element pointing to the target component
when this Panel is floating and shown by another component.
Defaults to:
false
Set the anchor position.
Defaults to:
null
Sets the value of anchorPosition
anchorPosition : String
If specified, load and submit (see formpanel) actions will be loaded and
submitted via Ext Direct. Methods which have been imported by
Ext.direct.Manager can be specified here to load and submit forms.
API methods may also be specified as strings and will be parsed into the actual functions when the first submit or load has occurred.
For example, instead of the following:
api: {
load: App.ss.MyProfile.load,
submit: App.ss.MyProfile.submit
}
You can use strings:
api: {
load: 'App.ss.MyProfile.load',
submit: 'App.ss.MyProfile.submit'
}
You can also use a prefix instead of fully qualified function names:
api: {
prefix: 'App.ss.MyProfile',
load: 'load',
submit: 'submit'
}
Load actions can use paramOrder or paramsAsHash to customize how the load is invoked.
For formpanel, submit actions will always use a standard form submit. The
formHandler configuration (see Ext.direct.RemotingProvider#action) must be
set on the associated server-side method which has been imported by
Ext.direct.Manager.
Defaults to:
null
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.
Ext.create({
xtype: 'container',
renderTo: Ext.getBody(),
height: 200,
width: 200,
style: 'background: green',
items: [{
xtype: 'component',
style: 'background: yellow',
height: '50%',
width: '50%'
}]
});
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
Optional set of params to be sent.
For formpanel this only applies when standardSubmit is set to false.
Defaults to:
null
Convenience config. Short for 'Bottom Bar'.
is equivalent to
Defaults to:
null
Available since: 6.5.0
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
Controls the border style of the panel body using the following values:
true to enable the border around the panel body (as defined by the theme)
Note that even when enabled, the bodyBorder is only visible when there are
docked items around the edges of the panel. Where the bodyBorder touches the
panel's outer border it is automatically collapsed into a single border.
false to disable the body border
null - use the value of border as the value for
bodyBorder
Defaults to:
null
The CSS class to add to this container's body element.
Defaults to:
null
Available since: 7.0
A shortcut for setting a padding style on the body element. The value can either be a number to be applied to all sides, or a normal CSS string describing padding.
bodyPadding: 5 // 5px padding on all sides
bodyPadding: '10 20' // 10px top and bottom padding - 20px side padding
See the unitizeBox method for more information on what string values are valid
Defaults to:
null
Custom CSS styles to be applied to the panel's body element, which can be supplied as a valid CSS style string or an object containing style property name/value pairs.
For example, these two formats are interpreted to be equivalent:
bodyStyle: 'background:#ffc; padding:10px;'
bodyStyle: {
background: '#ffc',
padding: '10px'
}
Defaults to:
null
Available since: 6.5.0
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:
false
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
Set to false to disable dirty states affecting ancestor containers such as
fieldpanel or formpanel. The dirty state of such containers is based on the
presence of dirty descendants. In some cases, however, it may be desired to
hide the dirty state of one of these containers from its ancestor containers.
Defaults to:
true
Available since: 7.0
The config for the calendar field.
Defaults to:
{
xtype: 'calendar-calendar-picker',
label: 'Calendar',
name: 'calendarId',
displayField: 'title',
valueField: 'id'
}
The config for the cancel button.
Defaults to:
{
text: 'Cancel',
handler: 'onCancelTap'
}
Animation to be used during transitions of cards.
This method has been REMOVED since 2.0.0
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
True to display the 'close' tool button and allow the user to close the panel or false to hide the button and disallow closing the window.
By default, when close is requested by clicking the close button in the header, the method-close method will be called. This will destroy the Panel and its content meaning that it may not be reused.
To make closing a Panel hide the Panel so that it may be reused, set closeAction to 'hide'.
Defaults to:
null
The action to take when the close header tool is clicked:
'method-destroy' :
remove the window from the DOM and destroy it and all descendant Components. The window will not be available to be redisplayed via the method-show method.
'method-hide' :
method-hide the window by setting visibility to hidden and applying negative offsets. The window will be available to be redisplayed via the method-show method.
Note: This behavior has changed! setting does affect the method-close method which will invoke the appropriate closeAction.
Defaults to:
'destroy'
Text to be announced by screen readers when the close <ext-tool/> <ext-paneltool/> is focused. Will also be set as the close tool's tooltip text.
Note: Applicable when the panel is closable: true
Defaults to:
'Close panel'
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
A configuration for a Ext.panel.Collapser.
True to make the panel collapsible and have an expand/collapse toggle Tool added into the header tool button area.
You can also set top/right/bottom/left to directly specify the collapse
direction.
IMPORTANT: To use this config, the application must require the following class:
requires: [
'Ext.panel.Collapser'
]
Defaults to:
null
Available since: 6.5.0
Returns the value of collapsible
Sets the value of collapsible
collapsible : 'top' / 'right' / 'bottom' / 'left' / Boolean / Object
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:
Ext.create({
xtype: 'container',
control: {
'button[text=Disable]': {
tap: 'hideMe'
}
},
hideMe: function() {
this.hide();
}
});
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 default start time for events. Should be in the
format [hour, minute].
Defaults to:
[
10,
0
]
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:
Ext.create({
xtype: 'container',
defaults: {
xtype: 'panel'
},
items: [
{
html: 'Panel 1'
},
{
html: 'Panel 2'
}
]
});
Defaults to:
null
The default start time for events. Should be in the
format [hour, minute].
Defaults to:
[
9,
0
]
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,

}
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:
container
The config for the description field.
Defaults to:
{
xtype: 'textareafield',
label: 'Description',
name: 'description',
flex: 1,
minHeight: '6em'
}
Sets the value of descriptionField
descriptionField : Object
This config property describes the modified state of this component. In most cases this config's value is maintained by the component and should be considered readonly. The class implementor should be the only one to call the setter.
For containers, this config will be updated on a short delay in some cases.
Defaults to:
false
Available since: 7.0
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
The config for the drop button. null to not show this button.
Defaults to:
{
text: 'Delete',
handler: 'onDropTap'
}
The submission form is generated but never added to the dom. It is a submittable version of your form panel, allowing for fields that are not simple textfields to be properly submitted to servers. It will also send values that are easier to parse with server side code.
If this is false we will attempt to subject the raw form inside the form panel.
Defaults to:
true
Sets the value of enableSubmissionForm
enableSubmissionForm : Boolean
The enctype attribute for the form, specifies how the form should be encoded when submitting.
Defaults to:
null
The config for the end date field.
Defaults to:
{
xtype: 'datepickerfield',
label: 'To',
itemId: 'endDate',
name: 'endDate'
}
The config for the end time field.
Defaults to:
{
xtype: 'calendar-timefield',
label: ' ',
itemId: 'endTime',
name: 'endTime'
}
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
The data for this form.
Defaults to:
null
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'
}
Deprecated since version 6.6.0
Inline event handlers are deprecated
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
The properties in this object are used as default config values for field instance.
Set to true to show separators between the fields in this form. Typically
used together with inputBorders to create iOS-like forms
Defaults to true in the iOS theme
Defaults to:
false
Sets the value of fieldSeparators
fieldSeparators : Boolean
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 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'
Force the component to take up 100% width and height available, by adding it to Ext.Viewport.
Pass as false to prevent a header from being created.
You may also assign a header with a config object (optionally containing an
xtype) to custom-configure your panel's header.
See <ext-panelheader/> for all the options that may be specified here.
Defaults to:
null
The position of the header. Ignored if no cfg-header is created.
Defaults to:
'top'
Available since: 6.5.0
Returns the value of headerPosition
'top' / 'right' / 'bottom' / 'left'
Sets the value of headerPosition
headerPosition : 'top' / 'right' / 'bottom' / 'left'
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
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
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
Path to an image to use as an icon.
For instructions on how you can use icon fonts including those distributed in the SDK see iconCls.
Defaults to:
null
The side of the title to render the icon.
Defaults to:
'left'
Returns the value of iconAlign
'top' / 'right' / 'bottom' / 'left'
Sets the value of iconAlign
iconAlign : 'top' / 'right' / 'bottom' / 'left'
One or more space separated CSS classes to be applied to the icon element. The CSS rule(s) applied should specify a background image to be used as the icon.
An example of specifying a custom icon class would be something like:
// specify the property in the config for the class:
iconCls: 'my-home-icon'
// css rule specifying the background image to be used as the icon image:
.my-home-icon {
background-image: url(../images/my-home-icon.gif) !important;
}
In addition to specifying your own classes, you can use the font icons provided in the SDK using the following syntax:
// using Font Awesome
iconCls: 'x-fa fa-home'
// using Pictos
iconCls: 'pictos pictos-home'
Depending on the theme you're using, you may need include the font icon packages in your application in order to use the icons included in the SDK. For more information see:
Defaults to:
null
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. This method Will auto-generate an id if one has not already
been configured.
id
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
false to suppress borders on the input elements of fields in this form.
Typically used together with fieldSeparators to create iOS-like forms.
Defaults to false in the iOS theme
Defaults to:
true
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:
Ext.create({
xtype: 'container',
items: [{
xtype: 'panel',
html: 'This is an item'
}]
});
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:
Ext.create({
xtype: 'tabpanel',
items: {
panel1: {
xtype: 'panel',
title: 'First panel'
},
panel2: {
xtype: 'panel',
title: 'Second panel'
}
}
});
Defaults to:
null
If set to true, the field values are sent as JSON in the request body.
All of the field values, plus any additional params configured via
baseParams and/or the options to submit,
will be included in the values POSTed in the body of the request.
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:
Ext.create({
xtype: 'container',
layout: {
type: 'hbox',
align: 'middle'
},
items: [{
xtype: 'panel',
flex: 1,
bodyStyle: {
background: "#000",
color:"#fff"
}
}, {
xtype: 'panel',
flex: 2,
bodyStyle: {
background: "#f00",
color:"#fff"
}
}]
});
Defaults to:
'auto'
Convenience config. Short for 'Left Bar' (left-docked, vertical toolbar).
is equivalent to
Defaults to:
null
Available since: 6.5.0
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:
true
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.
If the value is a string, it will be used as the message config for an <ext-loadmask/>.
For more precise control over the mask, 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.
Ext.create({
xtype: 'container',
fullscreen: true,
html: 'Hello World',
masked: {
xtype: 'loadmask',
message: 'My Message'
}
});
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 / String / Object / <ext-mask/> / <ext-loadmask/>
Sets the value of masked
masked : Boolean / String / 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
Minimum width of all buttonToolbar buttons in pixels. If set, this will be used as the default value for the Ext.Button#minWidth config of each <ext-button/> added to the `buttonToolbar via the buttons toolbar.
It will be ignored for buttons that have a minWidth configured some other
way, e.g. in their own config object or via the
defaults of their parent container.
Defaults to:
75
Available since: 6.5.0
Sets the value of minButtonWidth
minButtonWidth : Number
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
If this is enabled the form will automatically detect the need to use 'multipart/form-data' during submission.
Defaults to:
true
Sets the value of multipartDetection
multipartDetection : Boolean
Set to true for this component's name property to be tracked by its containing
nameHolder.
Forms can be assigned names to be used in parent forms.
Defaults to:
true
When true child components are tracked by their name property and can be
retrieved using the lookupName method.
Defaults to:
true
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
A list of params to be executed server side. Only used for the api config.
Specify the params in the order in which they must be executed on the server-side as either (1) a String[], or (2) a String of params delimited by either whitespace, comma, or pipe.
For example, any of the following would be acceptable:
paramOrder: ['param1','param2','param3']
paramOrder: 'param1 param2 param3'
paramOrder: 'param1,param2,param3'
paramOrder: 'param1|param2|param'
Defaults to:
null
If true, parameters will be sent as a single hash collection of named arguments. Providing a paramOrder nullifies this configuration.
Only used for the api config.
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'
});
In the above examples, the string "listpaging" is the type alias for
listpaging. The full alias includes the "plugin." prefix
(i.e., 'plugin.listpaging').
The preferred form for multiple plugins or to configure plugins is the keyed-object form (new in version 6.5):
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: {
pullrefresh: true,
listpaging: {
autoPaging: true,
weight: 10
}
}
});
The object keys are the id's as well as the default type alias. This form
allows the value of the plugins to be merged from base class to derived class
and finally with the instance configuration. This allows classes to define a
set of plugins that derived classes or instantiators can further configure or
disable. This merge behavior is a feature of the
config.
The plugins config can also be an array of plugin aliases (arrays are not
merged so this form does not respect plugins defined by the class author):
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
}]
});
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
Convenience config. Short for 'Right Bar' (right-docked, vertical toolbar).
is equivalent to
Defaults to:
null
Available since: 6.5.0
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
Optional element to render this Component to. Not required if this component is an item of a Container of a Container.
Defaults to:
null
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
A configuration for a Ext.panel.Resizer.
IMPORTANT: To use this config, the application must require the following class:
requires: [
'Ext.panel.Resizer'
]
Defaults to:
null
Available since: 6.5.0
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.
The config for the save button.
Defaults to:
{
text: 'Save',
handler: 'onSaveTap'
}
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:
true
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
This object contains config objects for the standard buttons (such as OK
and Cancel). This object is keyed by the itemId for the button and
contains the text and a default weight for
weighted containers to use. These default
weights vary by OS to provide the user with a button order that is consistent
for their platform. In particular, Windows and Linux (or rather all platforms
other then Mac OS and iOS) present the OK button followed by Cancel while
Mac OS and iOS present them in reverse order of 'Cancelfollowed byOK`.
The standard buttons, in weight order, are as follows:
okabortretryignoreyesnocancelapplysavesubmithelpcloseOn Mac OS and iOS this order is reversed with the exception of help which
is the first button. The buttons are assigned weights from 10 to 200.
Defaults to:
{
ok: {
text: 'OK',
weight: isMacOrAndroid ? 120 : 10
},
abort: {
text: 'Abort',
weight: isMacOrAndroid ? 110 : 20

Defaults to:
{
xtype: 'datepickerfield',
label: 'From',
itemId: 'startDate',
name: 'startDate'
}
Sets the value of startDateField
startDateField : Object
The config for the start time field.

Sets the value of startTimeField
startTimeField : Object
This config specifies the config properties that will be persisted using the
Ext.state.Provider. If this config is set to true, the
configs specified by statefulDefaults will be assumed.
stateful: true
Otherwise, this config can be an array of strings of the properties to save:
stateful: [
'width',
'height',
'collapsed'
]
The above is equivalent to:
stateful: {
width: true,
height: true,
collapsed: true
}
Note: To be truly stateful, an id or stateId must also be assigned.
A stateful object will save its state when any of these config properties change value.
Defaults to:
false
The default set of stateful properties. The form of this config is the same as stateful except this config cannot be a Boolean.
This config is intended for classes to specify so that instances can simply
enable statefulness using stateful: true.
Defaults to:
null
The unique id for this object to use for state management purposes.
Defaults to:
null
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
When this is set to true, the form will automatically submit itself whenever
the action event fires on a field in this form. The action event usually fires
whenever you press go or enter inside a textfield.
Defaults to:
false
Sets the value of submitOnAction
submitOnAction : Object
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
Convenience config. Short for 'Top Bar'.
is equivalent to
Defaults to:
null
Available since: 6.5.0
The title text or config object for the <ext-paneltitle/> component.
Defaults to:
null
The alignment of the title text within the available space between the icon and the tools.
Defaults to:
'left'
Returns the value of titleAlign
'left' / 'center' / 'right'
Sets the value of titleAlign
titleAlign : 'left' / 'center' / 'right'
true to allow expanding and collapsing the panel (when collapsible = true)
by clicking anywhere in the header bar, false to allow it only by clicking to tool
button.
Defaults to:
null
Available since: 7.0
The config for the title field.
Defaults to:
{
xtype: 'textfield',
label: 'Title',
name: 'title'
}
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/> <ext-paneltool/> 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-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
A String, Ext.Template, Ext.XTemplate or an Array of strings to form an Ext.XTemplate. Used in conjunction with the data and tplWriteMode configurations.
Note The data configuration must be set for any content to be shown in the component when using this configuration.
Defaults to:
null
Sets the value of tpl
tpl : String / String[] / Ext.Template / Ext.XTemplate[]
The Ext.(X)Template method to use when updating the content area of the Component.
Valid modes are:
Defaults to:
'overwrite'
If set to true, reset() resets to the last loaded or setValues data instead of when the form was first created.
Defaults to:
false
Sets the value of trackResetOnLoad
trackResetOnLoad : Boolean
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
Set to true to allow users to select text within this component.
Can also be any valid value for the CSS3 user-select property.
A value of true implies auto, while false implies none.
May also be an object keyed by child element name.
By default, the user cannot click+drag+select text/elements of the UI. Applications may want to enable user selection for specific DOM elements, such as the bodyElement of a component used as a tab panel. The tab and tab text would not be user selectable in this example, but the content area when the tab is selected would.
userSelectable: {
element: true, // allow the element to be user selectable
bodyElement: true // allow the component's body element to be user selectable
}
Defaults to:
false
Available since: 6.5.1
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/> like so:
Ext.define('PressMeButton', {
extend: 'Ext.button.Button',
xtype: '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
A prototype-chained object storing transform method names and priorities stored on the class prototype. On first instantiation, this object is converted into an array that is sorted by priority and stored on the constructor.
Defaults to:
{}
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.
true indicates an id was auto-generated rather than provided by configuration.
Defaults to:
false
Available since: 6.7.0
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:
Ext.baseCSSPrefix + 'panel'
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:
'title'
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 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:
Ext.baseCSSPrefix + 'floating'
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 panel has the collapsible override added.
Defaults to:
true
Available since: 6.5.0
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);
}
true if this panel has the resizable override added.
Defaults to:
true
Available since: 6.5.0
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
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 last key event processed is cached on the component for use in subsequent event handlers.
Available since: 6.6.0
The CSS class to add to this component should not have a border.
Defaults to:
Ext.baseCSSPrefix + 'noborder-trbl'
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:
[
{
reference: 'bodyWrapElement',
cls: Ext.baseCSSPrefix + 'body-wrap-el',
uiCls: 'body-wrap-el',
children: [
{
reference: 'bodyElement',
cls: Ext.baseCSSPrefix + 'body-el',
uiCls: 'body-el'
}
]
}
]
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)
Defaults to:
{
"true": Ext.baseCSSPrefix + 'user-selectable-auto',
"false": Ext.baseCSSPrefix + 'user-selectable-none',
all: Ext.baseCSSPrefix + 'user-selectable-all',
auto: Ext.baseCSSPrefix + 'user-selectable-auto',
text: Ext.baseCSSPrefix + 'user-selectable-text',
none: Ext.baseCSSPrefix + 'user-selectable-none'
}
Regular expression used for validating reference values.
Defaults to:
/^[a-z_][a-z0-9_]*$/i
Adds declarative listeners as nested arrays of listener objects.
listeners : Array
true if any listeners were added
This method is called before destroy to ensure that this instance's stateful
properties are saved to persistent storage. Since this object is about to be
destroyed, this cannot be delayed.
Creates a particular plugin type if defined in the plugins configuration.
Available since: 6.2.0
type : String
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.
Adds a CSS class to the body element. If not rendered, the class will be added when the panel is rendered.
cls : String
The class to add
this
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.
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.SomeSharedMenu, '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...'
});
Available since: 6.2.0
plugin : Object/String/Ext.plugin.Abstract
The plugin or config object or alias to add.
Add tools to this panel <ext-panelheader/>
panel.addTool({
type: 'gear',
handler: function () {
// ....
}
});
panel.addTool([{
type: 'gear',
handler: 'viewControllerGearMethod'
}, {
type: 'save',
handler: 'viewControllerSaveMethod'
}]);
By default the tools will be accessible via keyboard, with the exception of automatically added collapse/expand and close tools.
If you implement keyboard equivalents of your tools' actions elsewhere and do not want the tools to participate in keyboard navigation, you can make them presentational instead:
panel.addTool({
type: 'mytool',
focusable: false,
ariaRole: 'presentation'
// ...
});
tool : Object/Object[]/Ext.Tool/Ext.Tool[]
The tool or tools to add.
This method is called by descendants that use this mixin when their dirty state
changes.
dirty : Boolean
The dirty state of the descendant component.
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 method is called when the component hierarchy has changed and the current set
of descendants will be reasserting their dirty state. This method is only called
on nameHolder containers.
Bubbles up the getRefOwner hierarchy, calling the specified function
with each component. The scope (this reference) of the function call will be the
scope provided or the current component. The arguments to the function will
be the args provided or the current component. If the function returns false at any
point, the bubble is stopped.
fn : Function
The function to call
scope : Object (optional)
The scope of the function. Defaults to current node.
args : Array (optional)
The args to call the function with. Defaults to passing the current component.
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();
alert("Meeeeoooowwww");
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// 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.
this
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.
Marks all named fields as valid by calling setError() on each.
this
Collapses the panel body so that the body becomes hidden. Fires the Ext.Panel#beforecollapse event which will cancel the collapse action if it returns false.
It also fires the Ext.Panel#collapse event after the panel body is collapsed.

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.

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.
eventName : Object
args : Object
Continue to fire event.
eventName : String
args : Array
bubbles : Boolean
index : Number
item : Ext.Component
instanced : Boolean
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.
Expands the panel body so that it becomes visible. Fires the Ext.Panel#beforeexpand event which will cancel the expand action if it returns false.
It also fires the Ext.Panel#expand event after the panel is expanded.
animation : Boolean/Object
The animation to execute. This setting overrides any animation configuration. Do not pass a value to use the values configured on the class.
A promise that resolves when the expand completes.
Called when an item is added to this container either during initialization of the cfg-items config, or when new items are {@link #method!add added), or 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.
Set the fields of the provided record from the name
fields.
record : Ext.data.Model
this
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.
needsShow : Object
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.
This method is called when the component hierarchy has changed after the current set
of descendants has reasserted their dirty state. This method is only called on
nameHolder containers.
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.
To be called when a save takes place. Fires the save event.
data : Object
The form data.
This method is called after _fixReference() during the reference sync sweep. We
need to inform our parent if we are a leaf component and if we are dirty. If we are
a nameHolder then we'll inform the parent in finishSyncChildDirty.
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,

The name of the config property to get.
peek : Boolean (optional)
true to peek at the raw value without calling the getter.
Defaults to: false
ifInitialized : Boolean (optional)
true to only return the initialized property
value, not the raw config value, and not to trigger initialization. Returns
undefined if the property has not yet been initialized.
Defaults to: false
The config property value.

The id or index of the component to find.
The docked component, if found.
Returns all the Ext.Component#docked items in 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 Object returned is exactly the same as one that can be passed to setErrors.
Returns all <ext-field/> instances inside this form.
byName : String
Return an array of fields that match the given name. If only one field matches the name, only that instance will be returned.
