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

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

A base form implementation for data used with Ext.calendar.model.Event.
The item from the cfg-items collection that will be active first. This is usually only meaningful in a Ext.layout.Card, where only one item can be active at a time. If passes a string, it will be assumed to be a Ext.ComponentQuery selector.
Defaults to:
0
The config for the all day field.
Defaults to:
{
xtype: 'checkboxfield',
itemId: 'allDay',
name: 'allDay',
label: 'All Day',
listeners: {
change: 'onAllDayChange'
}
}
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
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 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. Such as the following:
api: {
load: App.ss.MyProfile.load,
submit: App.ss.MyProfile.submit
}
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 method
is invoked. 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
If true, child items will be destroyed as soon as they are removed
from this container.
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
The base CSS class to apply to this widget's element.
Used as the prefix for ui-specific class names.
When set to true the classCls will be used as the baseCls
Defaults to:
true
Optional hash of params to be sent (when standardSubmit configuration is false) on every submit.
Defaults to:
null
Setting this config option adds or removes data bindings for other configs.
For example, to bind the title config:
var panel = Ext.create({
xtype: 'panel',
bind: {
title: 'Hello {user.name}'
}
});
To dynamically add bindings:
panel.setBind({
title: 'Greetings {user.name}!'
});
To remove bindings:
panel.setBind({
title: null
});
The bind expressions are presented to Ext.app.ViewModel#bind. The
ViewModel instance is determined by lookupViewModel.
Note: If bind is passed as a string, it will use the Ext.Component#property-defaultBindProperty for the binding.
Defaults to:
null
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
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.
Defaults to:
null
Enables or disables bordering on this component. The following values are accepted:
null or `true (default): Do nothing and allow the border to be specified by the theme.false: suppress the default border provided by the theme.Please note that enabling bordering via this config will not add a border-color
or border-style CSS property to the component; you provide the border-color
and border-style via CSS rule or style configuration
(if not already provide by the theme).
Ext.Viewport.add({
centered: true,
width: 100,
height: 100,
style: 'border: 1px solid blue;'
// ...
});
Ext.Viewport.add({
centered: true,
width: 100,
height: 100,
cls: 'my-component'
// ...
});
And your CSS file:
.my-component {
border: 1px solid red;
}
Defaults to:
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
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, 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 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 close method which will invoke the appropriate closeAction.
Defaults to:
'destroy'
Text to be announced by screen readers when the close Ext.panel.Tool 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
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('Ext.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
]
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('Ext.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 Ext.Component of child Components to create in this Container when a child item is specified as a raw configuration object, rather than as an instantiated Component.
Defaults to:
null
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
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
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
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
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.
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
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.panel.Header for all the options that may be specified here.
Defaults to:
null
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
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
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 of this component. Will autogenerate an id if one has not already been set.
id
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 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('Ext.Container', {
items: [
{
xtype: 'panel',
html: 'This is an item'
}
]
});
Defaults to:
null
An object containing handlers for keyboard events. The property names of this object are the key name and any modifiers. The values of the properties are the descriptors of how to handle each event.
The handler descriptor can be simply the handler function (either the literal function or the method name), or it can be an object with these properties:
handler: The function or its name to call to handle the event.scope: The this pointer context (can be "this" or "controller").event: An optional override of the key event to which to listen.Important: Calls to setKeyMap do not replace the entire keyMap but
instead update the provided mappings. That is, unless null is passed as the
value of the keyMap which will clear the keyMap of all entries.
Defaults to:
null
scope : String
The default scope to apply to key handlers
which do not specify a scope. This is processed the same way as the scope of
cfg-listeners. It defaults to the "controller", but using 'this'
means that an instance method will be used.
Enables or disables processing keys in the keyMap. This value starts as
null and if it is null when initKeyMap is called, it will automatically
be set to true. Since initKeyMap is called by Ext.Component at the
proper time, this is not something application code normally handles.
Defaults to:
null
The name of the member that should be used to listen for keydown/keypress events. This is intended to be controlled at the class level not per instance.
Defaults to:
'el'
Configuration for this Container's layout. Example:
Ext.create('Ext.Container', {
layout: {
type: 'hbox',
align: 'middle'
},
items: [
{
xtype: 'panel',
flex: 1,
style: 'background-color: red;'
},
{
xtype: 'panel',
flex: 2,
style: 'background-color: green'
}
]
});
Defaults to:
'default'
The absolute left position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
Explicitly setting this value will make this Component become 'positioned', which means it will no
longer participate in the layout of the Container that it resides in.
Defaults to:
null
A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once.
DOM events from Ext JS Ext.Component
While some Ext JS Component classes export selected DOM events (e.g. "click", "mouseover" etc), this is usually
only done when extra value can be added. For example the DataView's itemclick event passing the node clicked on. To access DOM events directly from a
child element of a Component, we need to specify the element option to identify the Component property to add a
DOM listener to:
new Ext.panel.Panel({
width: 400,
height: 200,
dockedItems: [{
xtype: 'toolbar'
}],
listeners: {
click: {
element: 'el', //bind to the underlying el property on the panel
fn: function(){ console.log('click el'); }
},
dblclick: {
element: 'body', //bind to the underlying body property on the panel
fn: function(){ console.log('dblclick body'); }
}
}
});
An alias for addListener. In versions prior to 5.1, listeners had a generated setter which could be called to add listeners. In 5.1 the listeners config is not processed using the config system and has no generated setter, so this method is provided for backward compatibility. The preferred way of adding listeners is to use the on method.
listeners : Object
The listeners
true to enable border management of docked items. When enabled, borders of docked
items will collapse where they meet to avoid duplicated borders.
Defaults to:
false
The margin to use on this Component. Can be specified as a number (in which case all edges get the same margin) or a CSS string like '5 10 10 10'
Defaults to:
null
A configuration to allow you to mask this container.
You can optionally pass an object block with and xtype of loadmask, and an optional message value to
display a loading mask. Please refer to the Ext.LoadMask component to see other configurations.
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 / Object / Ext.Mask / Ext.LoadMask
Sets the value of masked
masked : Boolean / Object / Ext.Mask / Ext.LoadMask
The maximum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
If set to auto, it will set the width to null meaning it will have its own natural size.
Note that this config will not apply if the Component is 'positioned' (absolutely positioned or centered)
Defaults to:
null
The maximum width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
If set to auto, it will set the width to null meaning it will have its own natural size.
Note that this config will not apply if the Component is 'positioned' (absolutely positioned or centered)
Defaults to:
null
The minimum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
If set to auto, it will set the width to null meaning it will have its own natural size.
Defaults to:
null
The minimum width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
If set to auto, it will set the width to null meaning it will have its own natural size.
Defaults to:
null
true to make this Componenrt 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
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
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 load
configuration.
Specify the params in the order in which they must be executed on the server-side as either (1) an Array of String values, 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
Only used for the api load configuration. If true, parameters will be sent as a
single hash collection of named arguments. Providing a paramOrder nullifies this
configuration.
Defaults to:
null
An object or array of objects that will provide custom functionality for this
component. If a string is provided or a string is one of the elements of the
array, that string is treated as the type alias. For example, "listpaging"
is the type alias for Ext.plugin.ListPaging. The full alias includes the
"plugin." prefix (i.e., 'plugin.listpaging').
Plugins should derive from Ext.plugin.Abstract but this is not required. The
only requirement for a valid plugin is that it contain an init() method that
accepts a reference to the owning component.
When a component is created, if any plugins are available, the component will
call the init method on each plugin,
passing a reference to itself. Each plugin can then call methods or respond to
events on the component as needed to provide its functionality.
A plugin by alias:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: 'listpaging'
});
Multiple plugins by alias:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: ['listpaging', 'pullrefresh']
});
Single plugin by class name with config options:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: {
type: 'listpaging',
autoPaging: true
}
});
Multiple plugins by type and class name with config options:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: [{
xclass: 'Ext.plugin.PullRefresh',
pullRefreshText: 'Pull to refresh...'
}, {
type: 'listpaging',
autoPaging: true
}]
});
Defaults to:
null
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
The model instance of this form. Can by dynamically set at any time.
Defaults to:
null
Loads matching fields from a model instance into this form.
record : Ext.data.Model
The model instance.
This form.
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
Sets the value of referenceHolder
referenceHolder : Boolean
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. Usually this is not needed because a Component is normally full screen or automatically rendered inside another Ext.Container
Defaults to:
null
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
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
Whether or not we want to perform a standard form submit.
Defaults to:
false
Sets the value of standardSubmit
standardSubmit : Boolean
The config for the start date field.
Defaults to:
{
xtype: 'datepickerfield',
label: 'From',
itemId: 'startDate',
name: 'startDate'
}
Sets the value of startDateField
startDateField : Object
The config for the start time field.
Defaults to:
{
xtype: 'calendar-timefield',
label: ' ',
itemId: 'startTime',
name: 'startTime'
}
Sets the value of startTimeField
startTimeField : Object
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
The class that is added to the content target when you set styleHtmlContent to true.
Defaults to:
"x-html"
true to automatically style the HTML inside the content target of this component (body for panels).
Defaults to:
false
Sets the value of styleHtmlContent
styleHtmlContent : Boolean
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
The title text or config object for the Ext.panel.Title component.
Defaults to:
null
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
An array of Ext.panel.Tool configs/instances to be added to the header tool area. The tools are stored as child components of the header container.
Defaults to:
null
The tooltip for this component - can be a string to be used as innerHTML (html tags are accepted) or Ext.tip.ToolTip config object.
The default behavior is to use a shared tip instance. The tooltip configuration is registered with the Ext.tip.Manager. To enable this, your application can set the Ext.app.Application#quickTips config, or an instance of the Ext.tip.Manager may be created manually.
To force a unique tooltip instance to be created, specify autoCreate: true on this configuration.
Configuring this with autoHide: false implies autoCreate: true so that the desired persistent
behavior can be obtained with other targets still showing the singleton instance.
Defaults to:
null
The absolute top position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
Explicitly setting this value will make this Component become 'positioned', which means it will no
longer participate in the layout of the Container that it resides in.
Defaults to:
null
Emulates the behavior of the CSS href="https://www.w3.org/TR/pointerevents/#the-touch-action-css-property" class="external-link" target="_blank">https://www.w3.org/TR/pointerevents/#the-touch-action-css-property 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
Defaults to:
null
Sets the value of useBodyElement
useBodyElement : Boolean
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
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
The width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.
By default, if this is not explicitly set, this Component's element will simply have its own natural size.
If set to auto, it will set the width to null meaning it will have its own natural size.
Defaults to:
null
Only valid when a component is cfg-floated
The x position at which to position this component. This is usually viewport-relative. But if there is a
relative: true ancestor, it will be relative to that.
Defaults to:
0
The xtype configuration option can be used to optimize Component creation and rendering. It serves as a
shortcut to the full component name. For example, the component Ext.button.Button has an xtype of button.
You can define your own xtype on a custom Ext.Component by specifying the
alias config option with a prefix of widget. For example:
Ext.define('PressMeButton', {
extend: 'Ext.button.Button',
alias: 'widget.pressmebutton',
text: 'Press Me'
});
Any Component can be created implicitly as an object config with an xtype specified, allowing it to be declared and passed into the rendering pipeline without actually being instantiated as an object. Not only is rendering deferred, but the actual creation of the object itself is also deferred, saving memory and resources until they are actually needed. In complex, nested layouts containing many Components, this can make a noticeable improvement in performance.
// Explicit creation of contained Components:
var panel = new Ext.Panel({
// ...
items: [
Ext.create('Ext.button.Button', {
text: 'OK'
})
]
});
// Implicit creation using xtype:
var panel = new Ext.Panel({
// ...
items: [{
xtype: 'button',
text: 'OK'
}]
});
In the first example, the button will always be created immediately during the panel's initialization. With many added Components, this approach could potentially slow the rendering of the page. In the second example, the button will not be created or rendered until the panel is actually displayed in the browser. If the panel is never displayed (for example, if it is a tab that remains hidden) then the button will never be created and will never consume any resources whatsoever.
Only valid when a component is cfg-floated
The x position at which to position this component. This is usually viewport-relative. But if there is a
relative: true ancestor, it will be relative to that.
Defaults to:
0
The z-index to give this Component when it is rendered.
Not valid for cfg-floated Components. The Z ordering of cfg-floated Components is managed by ordering of the DOM elements.
Defaults to:
null
The value true causes config values to be stored on instances using a
property name prefixed with an underscore ("_") character. A value of false
stores config values as properties using their exact name (no prefix).
Defaults to:
true
Available since: 5.0.0
The value true instructs the initConfig method to only honor values for
properties declared in the config block of a class. When false, properties
that are not declared in a config block will be placed on the instance.
Defaults to:
true
Available since: 5.0.0
Matches options property names within a listeners specification object - property names which are never used as event names.
Defaults to:
{
scope: 1,
delay: 1,
buffer: 1,
onFrame: 1,
single: 1,
args: 1,
destroyable: 1,
priority: 1,
order: 1
}
We don't want the base destructor to clear the prototype because our destroyObservable handler must be called the very last. It will take care of the prototype after completing Observable destruction sequence.
Defaults to:
true
A CSS class to apply to the main element that will be inherited down the class hierarchy. Subclasses may override this property on their prototype to add their own CSS class in addition to the CSS classes inherited from ancestor classes via the prototype chain. For example
Ext.define('Foo', {
extend: 'Ext.Widget',
classCls: 'foo'
});
Ext.define('Bar', {
extend: 'Foo',
classCls: 'bar'
});
var bar = new Bar();
console.log(bar.element.className); // outputs 'foo bar'
Defaults to:
null
When set to true during widget class definition, that class will be the "root" for
classCls inheritance. Derived classes may set this to true to avoid
inheriting a classCls from their superclass.
Defaults to:
true
Setting this property to false will prevent nulling object references
on a Class instance after destruction. Setting this to "async" will delay
the clearing for approx 50ms.
Defaults to:
true
Available since: 6.2.0
Setting this property to true will result in setting the object's
prototype to null after the destruction sequence is fully completed.
After that, most attempts at calling methods on the object instance
will result in "method not defined" exception. This can be very helpful
with tracking down otherwise hard to find bugs like runaway Ajax requests,
timed functions not cleared on destruction, etc.
Note that this option can only work in browsers that support Object.setPrototypeOf
method, and is only available in debugging mode.
Defaults to:
false
Available since: 6.2.0
This property is used to determine the property of a bind config that is just
the value. For example, if defaultBindProperty="value", then this shorthand
bind config:
bind: '{name}'
Is equivalent to this object form:
bind: {
value: '{name}'
}
The defaultBindProperty is set to "value" for form fields and to "store" for
grids and trees.
Defaults to:
'html'
This property is set to true after the destroy method is called.
Defaults to:
false
A configuration object for Ext.Element.create() that is used to create the Element template. Supports all the standard options of a Ext.Element.create() config and adds 2 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.
Defaults to:
{
reference: 'element'
}
Initial suspended call count. Incremented when suspendEvents is called, decremented when resumeEvents is called.
Defaults to:
0
The CSS class to add to this component when it is floated at the viewport level.
Defaults to:
"x-floated"
The CSS class to add to this component's floatWrap when it's created.
Defaults to:
"x-float-wrap"
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);
}
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 CSS class to add to this component should not have a border.
Defaults to:
Ext.baseCSSPrefix + 'noborder-trbl'
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:
[]
Regular expression used for validating reference values.
Defaults to:
/^[a-z_][a-z0-9_]*$/i

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

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

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
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.
Clear a component reference.
component : Ext.Component
The component to remove.
Invalidates the references collection. Typically called when removing a container from this container, since it's difficult to know what references got removed.
Creates new Component.
config : Object
The standard configuration object.
Converts the provided type or config object into a plugin instance.
config : String/Object/Ext.plugin.Abstract
The plugin type, config object or instance.
Creates an event handling function which re-fires the event from this object as the passed event name.
newName : String
The name under which to re-fire the passed parameters.
beginEnd : Array (optional)
The caller can specify on which indices to slice.
Destroys the Widget. This method should not be overridden in custom Widgets, because it sets the flags and does final cleanup that must go last. Instead, override doDestroy method to add functionality at destruction time.
Removes and destroys a plugin.
Note: Not all plugins are designed to be removable. Consult the documentation for the specific plugin in question to be sure.
Available since: 6.2.0
plugin : String/Ext.plugin.Abstract
The plugin or its id to remove.
plugin instance or null if not found.
name : Object
fn : Object
scope : Object
options : Object
order : Object
caller : Object
manager : Object
Perform the actual destruction sequence. This is the method to override in your subclasses to add steps specific to the destruction of custom Component.
If the Component is currently added to a Container it will first be removed from that Container. All Ext.Element references are also deleted and the Component is de-registered from Ext.ComponentManager.
As a rule of thumb, subclasses should destroy their child Components, Elements, and/or other objects before calling parent method. Any object references will be nulled after this method has finished, to prevent the possibility of memory leaks.
Available since: 6.2.0
Fires a delegated event. Users should not invoke this method directly. It is called automatically by the framework as needed (see the "delegate" event option of addListener for more details.
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.
Called when an item is added to this container either during initialization of the cfg-items config, or when new items are added), or {@link #method-insert inserted.
If the passed object is not an instanced component, it converts the passed object into an instanced child component.
It applies cfg-defaults applied for contained child items - that is items which are not positiond using left, top, bottom, right, centered or docked.
Derived classes can override this method to process context appropriate short-hands such as Ext.Toolbar and "->" to insert a spacer.
item : Mixed
The item being added. May be a raw config object or an instanced Component or some other short-hand understood by the container.
The component to be added.
The method finds this floated component's floatParent. That means a DOM positioning container which acts as a root element for sibling floated components, and allows allows floated components to be absolutely positioned, and their encapsulating elements to be reordered to produce a visual stacking effect.
This component's element is appended to its floatParent.
There is a global floatParent element, created on demand when the first top level floated component
is shown. This may be an item child of a container configured with cfg-floated: true,
or a free floated component which is programatically shown.
Child items of components inside a floated component may also be configured floated. These
are give a floatParent which is created on demand wrapping the nearest floated ancestor.
This means that when that ancestor's element is brought to the top of the stack (by moving its
element to the end of its own floatParent), the descendant elements will automatically remain above.
Retrieves plugin by its type alias. For example:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: ['listpaging', 'pullrefresh']
});
list.findPlugin('pullrefresh').setPullRefreshText('Pull to refresh...');
Note: See also getPlugin.
Available since: 6.2.0
type : String
The Plugin's type as specified by the class's
alias configuration.
plugin instance or null if not found.
Fires the specified event with the passed parameters and executes a function (action).
By default, the action function will be executed after any "before" event handlers
(as specified using the order option of
addListener), but before any other
handlers are fired. This gives the "before" handlers an opportunity to
cancel the event by returning false, and prevent the action function from
being called.
The action can also be configured to run after normal handlers, but before any "after"
handlers (as specified using the order event option) by passing 'after'
as the order parameter. This configuration gives any event handlers except
for "after" handlers the opportunity to cancel the event and prevent the action
function from being called.
eventName : String
The name of the event to fire.
args : Array
Arguments to pass to handlers and to the action function.
fn : Function
The action function.
scope : Object (optional)
The scope (this reference) in which the handler function is
executed. If omitted, defaults to the object which fired the event.
options : Object (optional)
Event options for the action function. Accepts any
of the options of addListener
order : String (optional)
The order to call the action function relative
too the event handlers ('before' or 'after'). Note that this option is
simply used to sort the action function relative to the event handlers by "priority".
An order of 'before' is equivalent to a priority of 99.5, while an order of
'after' is equivalent to a priority of -99.5. See the priority option
of addListener for more details.
Defaults to: 'before'
Deprecated since version 5.5
Use fireEventedAction instead.
Fires the specified event with the passed parameters (minus the event name, plus the options object passed
to addListener).
An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.
eventName : String

An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.
eventName : String
The name of the event to fire.
args : Object[]
An array of parameters which are passed to handlers.
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

name : String (optional)
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
The config property value.

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

component is top level floated.
This method returns, or creates on demand the floatWrap element which wraps the passed floated component. It enables that floated component to act as a host for descendant floated components.
The passed component's floatWrap element.
Returns the stack of floated components in which this Component resides. This Component and all siblings at this level are returned.
selector : String/Function
A ComponentQuery selector, or
a selection function which returns true to select a component.
Returns the currently focused field
The currently focused field, if one is focused or null.
This method returns an object containing the inherited properties for this instance.
Available since: 5.0.0
inner : Boolean (optional)
Pass true to return inheritedStateInner instead
of the normal inheritedState object. This is only needed internally and should
not be passed by user code.
Defaults to: false
The inheritedState object containing inherited properties.
This method returns the value of a config property that may be inherited from some ancestor.
In some cases, a config may be explicitly set on a component with the intent of
only being presented to its children while that component should act upon the
inherited value (see referenceHolder for example). In these cases the skipThis
parameter should be specified as true.
Available since: 5.0.0
property : String
The name of the config property to return.
skipThis : Boolean (optional)
Pass true if the property should be ignored if
found on this instance. In other words, true means the property must be inherited
and not explicitly set on this instance.
Defaults to: false
The value of the requested property.
Returns the initial configuration passed to the constructor when instantiating this class.
Given this example Ext.button.Button definition and instance:
Ext.define('MyApp.view.Button', {
extend: 'Ext.button.Button',
xtype: 'mybutton',
scale: 'large',
enableToggle: true
});
var btn = Ext.create({
xtype: 'mybutton',
renderTo: Ext.getBody(),
text: 'Test Button'
});
Calling btn.getInitialConfig() would return an object including the config
options passed to the create method:
xtype: 'mybutton',
renderTo: // The document body itself
text: 'Test Button'
Calling btn.getInitialConfig('text')returns 'Test Button'.
name : String (optional)
Name of the config option to return.
The full config object or a single config value
when name parameter specified.
Returns all inner items of this container. inner means that the item is not docked or
positioned.

The next field if one exists, or false.
Returns the parent of this component, if it has one.
The parent of this component.
Retrieves a plugin by its id.
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: {
xclass: 'Ext.plugin.PullRefresh',
id: 'foo'
}
});
list.getPlugin('foo').setPullRefreshText('Pull to refresh...');
Note: See also findPlugin.
Available since: 6.2.0
id : String
The id of the plugin.
plugin instance or null if not found.
The next field if one exists, or false.
Used by ComponentQuery to retrieve all of the items
which can potentially be considered a child of this Container.
This should be overridden by components which have child items
that are not contained in items. For example dockedItems, menu, etc
deep : Object
Used by Ext.ComponentQuery, and the up method to find the owning Component in the linkage hierarchy.
By default this returns the Container which contains this Component.
This may be overridden by Component authors who implement ownership hierarchies which are not based upon ownerCt, such as BoundLists being owned by Fields or Menus being owned by Buttons.
Returns an object holding the descendants of this view keyed by their
reference. This object should not be held
past the scope of the function calling this method. It will not be valid if items
are added or removed from this or any sub-container.
The intended usage is shown here (assume there are 3 components with reference values of "foo", "bar" and "baz" at some level below this container):
onClick: function () {
var refs = this.getReferences();
// using "refs" we can access any descendant by its "reference"
refs.foo.getValue() + refs.bar.getValue() + refs.baz.getValue();
}
If this component has a reference assigned
to it, that is not included in this object. That reference is understood to
belong to the ancestor container configured as the referenceHolder.
Available since: 5.0.0
An object with each child reference. This will be null if this
container has no descendants with a reference
specified.
Returns an object containing the value of each field in the form, keyed to the field's name. For groups of checkbox fields with the same name, it will be arrays of values. For example:
{
name: "Jacky Nguyen", // From a TextField
favorites: [
'pizza',
'noodle',
'cake'
]
}
enabled : Boolean (optional)
true to return only enabled fields.
all : Boolean (optional)
true to return all fields even if they don't have a
name configured.
Object mapping field name to its value.
Returns this Component's xtype hierarchy as a slash-delimited string. For a list of all available xtypes, see the Ext.Component header.
Note: If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.
Example usage:
var t = new Ext.field.Text();
alert(t.getXTypes()); // alerts 'component/field/textfield'
The xtype hierarchy string.
Checks to see if this object has any listeners for a specified event, or whether the event bubbles. The answer indicates whether the event needs firing or not.

true if the event is being listened for or bubbles, else false
Returns true if this component has a parent.
true if this component has a parent.
Hides this Component optionally using an animation.

Deprecated since version 2.0.0
Please use unmask or setMasked instead.
This method triggers the lazy configs and must be called when it is time to
fully boot up. The configs that must be initialized are: bind, publishes,
session, twoWayBindable and viewModel.
Available since: 5.0.0
Initialize configuration for this class. a typical example:
Ext.define('My.awesome.Class', {
// The default config
config: {
name: 'Awesome',
isAwesome: true
},
constructor: function(config) {
this.initConfig(config);
}
});
var awesome = new My.awesome.Class({
name: 'Super Awesome'
});
alert(awesome.getName()); // 'Super Awesome'
instanceConfig : Object
this
Initializes the Element for this Widget instance. If this is the first time a Widget of this type has been instantiated the element config will be processed to create an Element. This Element is then cached on the prototype (see afterCachedConfig) so that future instances can obtain their element by simply cloning the Element that was cached by the first instance.
Called for the first instance of this Widget to create an object that contains the listener configs for all of the element references keyed by reference name. The object is cached on the prototype and has the following shape:
_elementListeners: {
element: {
click: 'onClick',
scope: this
},
fooReference: {
tap: {
fn: someFunction,
delay: 100
}
}
}
The returned object is prototype chained to the _elementListeners object of its superclass, and each key in the object is prototype chained to object with the corresponding key in the superclass _elementListeners. This allows element listeners to be inherited and overridden when subclassing widgets.
This method is invoked with the prototype object as the scope
elementConfig : Object
This method is called to initialize the inheritedState objects for this instance.
This amounts to typically copying certain properties from the instance to the given
object.
Available since: 5.0.0
inheritedState : Object
The state object for this instance.
inheritedStateInner : Object (optional)
This object is only provided for containers.
This method should be called when the instance is ready to start listening for
keyboard events. This is called automatically for Ext.Component and derived
classes. In Classic Toolkit, this is done after the component is rendered.
Adds a child Component at the given index. For example, here's how we can add a new item, making it the first child Component of this Container:
myContainer.insert(0, {xtype: 'panel', html: 'new item'});
index : Number
The index to insert the Component at.
item : Object
The Component to insert.
This method marks the current inherited state as invalid. The next time a call is
made to getInherited the objects will be recreated and initialized.
Available since: 5.0.0

Tests whether or not this Component is of a specific xtype. This can test whether this Component is descended
from the xtype (default) or whether it is directly of the xtype specified (shallow = true).
**If using your own subclasses, be aware that a Component must register its own xtype
to participate in determination of inherited xtypes.__
For a list of all available xtypes, see the Ext.Component header.
Example usage:
var t = new Ext.field.Text();
var isText = t.isXType('textfield'); // true
var isBoxSubclass = t.isXType('field'); // true, descended from Ext.field.Field
var isBoxInstance = t.isXType('field', true); // false, not a direct Ext.field.Field instance
xtype : String
The xtype to check for this Component.
shallow : Boolean (optional)
false to check whether this Component is descended from the xtype (this is
the default), or true to check whether this Component is directly of the specified xtype.

Available since: 5.0.0
skipThis : Boolean (optional)
false to return this as the reference holder if
this instance has set referenceHolder. Unlike getInheritedConfig this method
defaults to true because it is possible that a reference property set by the
owner of a component that is also a referenceHolder itself. In this case, the
reference connects not to this component but to the parent referenceHolder.
Defaults to: true
The reference holder.

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

Returns true if the passed element is within the container tree of this component.
For example if a menu's submenu contains an Ext.form.field.Date, that top level menu owns the elements of the date picker. Using this method, you can tell if an event took place within a certain component tree.
element : Object
Recursively processes the element templates for this class and its superclasses, ascending the hierarchy until it reaches a superclass whose element template has already been processed. This method is invoked using the prototype as the scope.
Publish this components state to the ViewModel. If no arguments are given (or if
this is the first call), the entire state is published. This state is determined by
the publishes property.
This method is called only by component authors.

The id to find
The matching id, null if not found
Relays selected events from the specified Observable as if the events were fired by this.
For example if you are extending Grid, you might decide to forward some events from store. So you can do this inside your initComponent:
this.relayEvents(this.getStore(), ['load']);
The grid instance will then have an observable 'load' event which will be passed the parameters of the store's load event and any function fired with the grid's load event would have access to the grid using the this keyword (unless the event is handled by a controller's control/listen event listener in which case 'this' will be the controller rather than the grid).
origin : Object
The Observable whose events this object is to relay.
events : String[]/Object
Array of event names to relay or an Object with key/value pairs translating to ActualEventName/NewEventName respectively. For example: this.relayEvents(this, {add:'push', remove:'pop'});
Would now redispatch the add event of this as a push event and the remove event as a pop event.
prefix : String (optional)
A common prefix to prepend to the event names. For example:
this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.
A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:
this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
Can be undone by calling
Ext.destroy(this.storeRelayers);
or this.store.relayers.destroy();

eventName : String
The type of event the handler was associated with.
fn : Function
The handler to remove. This must be a reference to the function passed into the addListener call.
scope : Object (optional)
The scope originally specified for the handler. It must be the same as the scope argument specified in the original call to Ext.util.Observable#addListener or the listener will not be removed.
Convenience Syntax
You can use the addListener
destroyable: true config option in place of calling un(). For example:
var listeners = cmp.on({
scope: cmp,
afterrender: cmp.onAfterrender,
beforehide: cmp.onBeforeHide,
destroyable: true
});
// Remove listeners
listeners.destroy();
// or
cmp.un(
scope: cmp,
afterrender: cmp.onAfterrender,
beforehide: cmp.onBeforeHide
);
Exception - DOM event handlers using the element config option
You must go directly through the element to detach an event handler attached using the addListener element option.

Resumes firing events (see suspendEvents).
If events were suspended using the queueSuspended parameter, then all events fired
during event suspension will be sent to any listeners now.

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

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

Performs a Ajax-based submission of form values (if standardSubmit is false) or otherwise executes a standard HTML Form submit action.
Notes
Only the first parameter is implemented. Put all other parameters inside the first parameter:
submit({params: "" ,headers: "" etc.})
Submit example:
myForm.submit({ url: 'PostMyData/To', method: 'Post', success: function() { Ext.Msg.alert("success"); }, failure: function() { Ext.Msg.alert("error"); } });
Parameters and values only submit for a POST and not for a GET.

The params to pass when submitting this form (defaults to this forms baseParams). Parameters are encoded as standard HTTP parameters using Ext#urlEncode.
submitDisabled : Boolean (optional)
true to submit all fields regardless of disabled state.
Note: Has no effect when standardSubmit is enabled.
Defaults to:
false
success : Function
The callback that will be invoked after a successful response. A response is successful if
a response is received from the server and is a JSON object where the success property is set
to true, {"success": true}.
The function is passed the following parameters and can be used for submitting via Ajax or Direct:
form : Ext.form.Panel
The Ext.form.Panel that requested the action.
result : Object/Ext.direct.Event
The result object returned by the server as a result of the submit request. If the submit is sent using Ext Direct, this will return the Ext.direct.Event instance, otherwise will return an Object.
data : Object
The parsed data returned by the server.
failure : Function
The callback that will be invoked after a failed transaction attempt.
The function is passed the following parameters and can be used for submitting via Ajax or Direct:

result : Ext.form.Panel
The failed response or result object returned by the server which performed the operation.
scope : Object
The scope in which to call the callback functions (The this reference for the callback functions).
The request object if the standardSubmit config is false. If the standardSubmit config is true, then the return value is undefined.
Suspends firing of the named event(s).
After calling this method to suspend events, the events will no longer fire when requested to fire.
Note that if this is called multiple times for a certain event, the converse method resumeEvent will have to be called the same number of times for it to resume firing.

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

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