The documentation for the ExtReact product diverges somewhat from the
documentation of other Sencha products. The sections below describe
documentation for all products except where indicated as unique to
ExtReact.
Many classes have shortcut names used when creating (instantiating) a class with a
configuration object. The shortcut name is referred to as an alias (or xtype if the
class extends Ext.Component). The alias/xtype is listed next to the class name of
applicable classes for quick reference.
ExtReact component classes list the configurable name prominently at the top of the API class doc followed by the fully-qualified class name.
Framework classes or their members may be specified as private or protected. Else,
the class / member is public. Public, protected, and private are access
descriptors used to convey how and when the class or class member should be used.
Public classes and class members are available for use by any other class or application code and may be relied upon as a stable and persistent within major product versions. Public classes and members may safely be extended via a subclass.
Protected class members are stable public members intended to be used by the
owning class or its subclasses. Protected members may safely be extended via a subclass.
Private classes and class members are used internally by the framework and are not intended to be used by application developers. Private classes and members may change or be omitted from the framework at any time without notice and should not be relied upon in application logic.
ExtReact component classes display
configuration options as props
ExtReact component classes do not list
properties as a dedicated member type, but rather as
read only props
static label next to the
method name. *See Static below.Below is an example class member that we can disect to show the syntax of a class member (the lookupComponent method as viewed from the Ext.button.Button class in this case).
Let's look at each part of the member row:
lookupComponent in this example)( item ) in this example)Ext.Component in this case). This may be omitted for methods that do not
return anything other than undefined or may display as multiple possible values
separated by a forward slash / signifying that what is returned may depend on the
results of the method call (i.e. a method may return a Component if a get method calls is
successful or false if unsuccessful which would be displayed as
Ext.Component/Boolean).PROTECTED in
this example - see the Flags section below)Ext.container.Container in this example). The source
class will be displayed as a blue link if the member originates from the current class
and gray if it is inherited from an ancestor or mixed-in class.view source in the example)item : Object in the example).undefined a "Returns" section
will note the type of class or object returned and a description (Ext.Component in the
example)Available since 3.4.0 - not pictured in
the example) just after the member descriptionDefaults to: false)The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.
All ExtReact props are bindable
unless decorated as immutable
Immutable ExtReact props may not be use as a configurable prop when instantiating a component
classInstance.method1().method2().etc();false is returned from
an event handler- Indicates a framework class
- A singleton framework class. *See the singleton flag for more information
- A component-type framework class (any class within the Ext JS framework that extends Ext.Component)
- Indicates that the class, member, or guide is new in the currently viewed version

- Indicates that the class, member, or guide is new in the currently viewed version
Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type (this count is updated as filters are applied). Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.
Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.
ExtReact component classes do not hoist the getter /
setter methods into the prop. All methods will be described in the
Methods section
Your page history is kept in localstorage and displayed (using the available real estate) just below the top title bar. By default, the only search results shown are the pages matching the product / version you're currently viewing. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. This will show all recent pages in the history bar for all products / versions.
Within the history config menu you will also see a listing of your recent page visits. The results are filtered by the "Current Product / Version" and "All" radio options. Clicking on the button will clear the history bar as well as the history kept in local storage.
If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled. When checked, the product/version for each historic page will show alongside the page name in the history bar. Hovering the cursor over the page names in the history bar will also show the product/version as a tooltip.
Both API docs and guides can be searched for using the search field at the top of the page.
On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.
The checkbox at the bottom of the API class navigation tree filters the class list to include or exclude private classes.
Clicking on an empty search field will show your last 10 searches for quick navigation.
Each API doc page (with the exception of Javascript primitives pages) has a menu view of metadata relating to that class. This metadata view will have one or more of the following:
Ext.button.Button class has an alternate class name of Ext.Button). Alternate class
names are commonly maintained for backward compatibility.Runnable examples (Fiddles) are expanded on a page by default. You can collapse and expand example code blocks individually using the arrow on the top-left of the code block. You can also toggle the collapse state of all examples using the toggle button on the top-right of the page. The toggle-all state will be remembered between page loads.
Class members are collapsed on a page by default. You can expand and collapse members using the arrow icon on the left of the member row or globally using the expand / collapse all toggle button top-right.
Viewing the docs on narrower screens or browsers will result in a view optimized for a smaller form factor. The primary differences between the desktop and "mobile" view are:
The class source can be viewed by clicking on the class name at the top of an API doc page. The source for class members can be viewed by clicking on the "view source" link on the right-hand side of the member row.

The Form panel presents a set of form fields and provides convenient ways to load and save data. Usually a form panel just contains the set of fields you want to display.
You can load data into forms in a few different ways, the easiest is to use setValues:
form.setValues({
name: 'Peter',
email: '[email protected]',
password: 'secret'
});
It's also easy to load Ext.data.Model instances into a form.
Getting data out of the form panel is simple and is usually achieve via the getValues method:
var values = form.getValues();
//values now looks like this:
{
name: 'Peter',
email: '[email protected]',
password: 'secret'
}
It's also possible to listen to the change events on individual fields to get more timely notification of changes that the user is making. Here we expand on the example above with the User model, updating the model as soon as any of the fields are changed:
While you can call Ext.field.Field#markInvalid and Ext.field.Field#clearInvalid on each field, in your form, FormPanel provides a setErrors method that will apply an Object of error states to multiple fields with one call:
formpanel.setErrors({
field1: 'field1 is in error', // markInvalid on the field
name2: 'field2 is in error', // markInvalid on the field
fieldname3: null, // clearInvalid on the field
fieldname4: [ 'one', 'two', 'three' }, // multiple errors on one field
...
});
While you can call Ext.field.Field#getActiveErrors on each field in the form to query the form for errors, you can call getErrors on the form to get an array of error states, suitable to pass into setErrors.
NOTE: these methods will only work on fields that are named.
There are a few ways to submit form data. In our example above we have a Model instance that we have updated, giving us the option to use the Model's save method to persist the changes back to our server, without using a traditional form submission. Alternatively, we can send a normal browser form submit using the method method:
form.submit({
url: 'url/to/submit/to',
method: 'POST',
success: function() {
alert('form submitted successfully!');
}
});
In this case we provided the url to submit the form to inside the submit call - alternatively you can just set the
url configuration when you create the form. We can specify other parameters (see method for a
full list), including callback functions for success and failure, which are called depending on whether or not the
form submission was successful. These functions are usually used to take some action in your app after your data
has been saved to the server side.
DOM tabIndex attribute to set on the active Focusable child of this container when using the "Roaming tabindex" technique.
Defaults to:
0
The item from the cfg-items collection that will be active first. This is usually only meaningful in a Ext.layout.Card, where only one item can be active at a time. If passed a string, it will be assumed to be a Ext.ComponentQuery selector. A number will reference an index or a Ext.Component instance may be passed as well. An object config will be created as a new component.
Defaults to:
0
Set this to true
to enable focusing disabled child items via keyboard.
Defaults to:
false
Configure true to show an anchor element pointing to the target component
when this Panel is floating and shown by another component.
Defaults to:
false
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
An object containing ARIA attributes to be set
on this Component's ARIA element. Use this to set the attributes that cannot be
determined by the Component's state, such as aria-live, aria-flowto, etc.
Note that this config is only meaningful at the Component rendering time, and setting it after that will do nothing.
DOM selector for a child element that is to be used
as description for this Component, set in aria-describedby attribute.
The selector works the same way as ariaLabelledBy.
ARIA label for this Component. It is best to use
ariaLabelledBy option instead, because screen readers prefer
aria-labelledby attribute to aria-label. ariaLabel and
ariaLabelledBy config options are mutually exclusive.
DOM selector for a child element that is to be used
as label for this Component, set in aria-labelledby attribute.
If the selector is by #id, the label element can be any existing element,
not necessarily a child of the main Component element.
ariaLabelledBy and ariaLabel config options are
mutually exclusive, and ariaLabelledBy has the higher precedence.
If true, child items will be destroyed as soon as they are
removed from this container.
Defaults to:
true
May be set to false for improved layout performance if auto-sizing is not required.
Some versions of Safari, both desktop and mobile, have very slow performance if the application has deeply nested containers due to the following WebKit bug: https://bugs.webkit.org/show_bug.cgi?id=150445
Applications that experience performance issues in the affected versions of
Safari may need to turn off autoSizing globally for all Container instances
by placing the following override in the application's "overrides" directory:
Ext.define('MyApp.overrides.Container', {
override: 'Ext.Container',
config: {
autoSize: false
}
});
Once auto-sizing support has turned off by default, it can be selectively
turned back on only on those container instances that explicitly need auto-sizing
behavior by setting autoSize to true.
This option can also be used to allow items to be sized in percentage units as a workaround for the following browser bug: https://bugs.webkit.org/show_bug.cgi?id=137730
To illustrate, the following example should render a 200px by 200px green box
(the container) with a yellow box inside of it (the child item). The child
item's height and width are both set to '50%' so the child should render
exactly 100px by 100px in size.
All browsers except for Safari render the previous example correctly, but
Safari does not assign a height to the component. To make percentage-sized
items work in Safari, simply set autoSize to false on the container.
Since the underlying implementation works by absolutely positioning the container's
body element, this option can only be used when the container is not
"shrink wrapping" the content in either direction. When autoSize is
set to false, shrink wrapped dimension(s) will collapse to 0.
Defaults to:
true
If true, then, when showBy or alignTo fallback on
constraint violation only takes place along the major align axis.
That is, if alignment "l-r" is being used, and axisLock: true is used,
then if constraints fail, only fallback to "r-l" is considered.
Defaults to:
null
Optional hash of params to be sent (when standardSubmit configuration is false) on every submit.
Defaults to:
null
Convenience config. Short for 'Bottom Bar'.
is equivalent to
Defaults to:
null
Available since: 6.5.0
Controls the border style of the panel body using the following values:
true to enable the border around the panel body (as defined by the theme)
Note that even when enabled, the bodyBorder is only visible when there are
docked items around the edges of the panel. Where the bodyBorder touches the
panel's outer border it is automatically collapsed into a single border.
false to disable the body border
null - use the value of border as the value for
bodyBorder
Defaults to:
null
A shortcut for setting a padding style on the body element. The value can either be a number to be applied to all sides, or a normal CSS string describing padding.
bodyPadding: 5 // 5px padding on all sides
bodyPadding: '10 20' // 10px top and bottom padding - 20px side padding
See the unitizeBox method for more information on what string values are valid
Defaults to:
null
Custom CSS styles to be applied to the panel's body element, which can be supplied as a valid CSS style string or an object containing style property name/value pairs.
For example, these two formats are interpreted to be equivalent:
bodyStyle: 'background:#ffc; padding:10px;'
bodyStyle: {
background: '#ffc',
padding: '10px'
}
Defaults to:
null
Available since: 6.5.0
Enables or disables bordering on this component. The following values are accepted:
null or `true (default): Do nothing and allow the border to be specified by the theme.false: suppress the default border provided by the theme.Please note that enabling bordering via this config will not add a border-color
or border-style CSS property to the component; you provide the border-color
and border-style via CSS rule or style configuration
(if not already provide by the theme).
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
Animation to be used during transitions of cards.
This method has been REMOVED since 2.0.0
Configure this as true to have this Component centered within its Container.
Setting this value to true will make this Component become 'positioned', which means
it will no longer participate in the layout of the Container that it resides in.
Defaults to:
false
True to display the 'close' tool button and allow the user to close the panel or false to hide the button and disallow closing the window.
By default, when close is requested by clicking the close button in the header, the method-close method will be called. This will destroy the Panel and its content meaning that it may not be reused.
To make closing a Panel hide the Panel so that it may be reused, set closeAction to 'hide'.
Defaults to:
null
The action to take when the close header tool is clicked:
'destroy' :
remove the window from the DOM and destroy it and all descendant Components. The window will not be available to be redisplayed via the method-show method.
'method-hide' :
method-hide the window by setting visibility to hidden and applying negative offsets. The window will be available to be redisplayed via the method-show method.
Note: This behavior has changed! setting does affect the method-close method which will invoke the appropriate closeAction.
Defaults to:
'destroy'
Text to be announced by screen readers when the close Ext.Tool 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 Container).
Defaults to:
null
A configuration for a Ext.panel.Collapser.
True to make the panel collapsible and have an expand/collapse toggle Tool added into the header tool button area.
You can also set top/right/bottom/left to directly specify the collapse
direction.
Defaults to:
null
Available since: 6.5.0
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
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
Specifies a child Component to receive focus when this Container's method-focus method is called. Should be a valid Ext.ComponentQuery selector.
Defaults to:
null
The default weight for tools in the header.
Defaults to:

Available since: 6.5.0
A set of default configurations to apply to all child Components in this Container. It's often useful to specify defaults when creating more than one items with similar configurations. For example here we can specify that each child is a panel and avoid repeating the xtype declaration for each one:
Defaults to:
null
Set to true to call show and false to call hide. Unlike the hidden
config, changing this config will potentially involve animations to show or
hide the component.
Defaults to:
null
Available since: 6.5.0
The dock position of this component in its container. Can be left, top, right or
bottom.
Notes
You must use a HTML5 doctype for docked bottom to work. To do this, simply
add the following code to the HTML file:
<!doctype html>
So your index.html file should look a little like this:
<!doctype html>
<html>
<head>
<title>MY application title</title>
...
Defaults to:
null
Set to true to allow this component to be dragged. This can also be the config
object for the Ext.drag.Source that will manage the drag.
Defaults to:
null
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
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 text-fields 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
The enctype attribute for the form, specifies how the form should be encoded when submitting.
Defaults to:

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.
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'.
If this property is specified by the target class of this mixin its properties are
used to configure the created Ext.Factory.
The properties in this object are used as default config values for field instance.
Set to true to show separators between the fields in this form. Typically
used together with inputBorders to create iOS-like forms
Defaults to true in the iOS theme
Defaults to:
false
CSS class that will be added to focused component's focusClsEl, and removed when component blurs.
Defaults to:
'x-focused'
The element that will have the focusCls applied when component's focusEl is focused.
The element that will be focused when focus method is called on this component. Usually this is the same element that receives focus via mouse clicks, taps, and pressing Tab key.
Defaults to:
'el'
Enable or disable navigation with arrow keys for this FocusableContainer. This option may be useful with nested FocusableContainers, when only the root container should handle keyboard events.
Defaults to:
false
The name of the element that FocusableContainer should bind its keyboard handler to. Similar to ariaEl, this name is resolved to the Ext.dom.Element instance after rendering.
Defaults to:
"el"
Force the component to take up 100% width and height available, by adding it to Ext.Viewport.
true if this panel has the collapsible override added.
Defaults to:
true
Available since: 6.5.0
true if this panel has the resizable override added.
Defaults to:
true
Available since: 6.5.0
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 position of the header. Ignored if no cfg-header is created.
Defaults to:
'top'
Available since: 6.5.0
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
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
Path to an image to use as an icon.
For instructions on how you can use icon fonts including those distributed in the SDK see iconCls.
Defaults to:
null
The side of the title to render the icon.
Defaults to:
'left'
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
DOM tabIndex attribute to set on inactive Focusable children of this container when using the "Roaming tabindex" technique. This value rarely needs to be changed from its default.
Defaults to:
-1
A string to add to the immediate parent element of the inner items of this
container. That is, items that are not docked, positioned or floated. In
some containers, positioned items may be in this same element.
Defaults to:
null
Available since: 6.5.0
false to suppress borders on the input elements of fields in this form.
Typically used together with fieldSeparators to create iOS-like forms.
Defaults to false in the iOS theme
Defaults to:
true
true in this class to identify an object as an instantiated Container, or subclass thereof.
Defaults to:
true
true in this class to identify an object as an instantiated Observable, or subclass thereof.
Defaults to:
true
If set to true, the field values are sent as JSON in the request body.
All of the field values, plus any additional params configured via
baseParams and/or the options to submit,
will be included in the values POSTed in the body of the request.
An object containing handlers for keyboard events. The property names of this object are the key name and any modifiers. The values of the properties are the descriptors of how to handle each event.
The handler descriptor can be simply the handler function (either the literal function or the method name), or it can be an object with these properties:
handler: The function or its name to call to handle the event.scope: The this pointer context (can be "this" or "controller").event: An optional override of the key event to which to listen.Important: Calls to setKeyMap do not replace the entire keyMap but
instead update the provided mappings. That is, unless null is passed as the
value of the keyMap which will clear the keyMap of all entries.
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
Configuration for this Container's layout. Example:
Defaults to:
'auto'
Convenience config. Short for 'Left Bar' (left-docked, vertical toolbar).
is equivalent to
Defaults to:
null
Available since: 6.5.0
The absolute left position of this Component; must be a valid CSS length value,
e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component
become 'positioned', which means it will no longer participate in the layout of the
Container that it resides in.
Defaults to:
null
A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once.
DOM events from Ext JS Ext.Component
While some Ext JS Component classes export selected DOM events (e.g. "click", "mouseover" etc), this is usually
only done when extra value can be added. For example the DataView's itemclick event passing the node clicked on. To access DOM events directly from a
child element of a Component, we need to specify the element option to identify the Component property to add a
DOM listener to:
new Ext.panel.Panel({
width: 400,
height: 200,
dockedItems: [{
xtype: 'toolbar'
}],
listeners: {
click: {
element: 'el', //bind to the underlying el property on the panel
fn: function(){ console.log('click el'); }
},
dblclick: {
element: 'body', //bind to the underlying body property on the panel
fn: function(){ console.log('dblclick body'); }
}
}
});
true to enable border management of docked items. When enabled, borders of docked
items will collapse where they meet to avoid duplicated borders.
Defaults to:
true
The margin to use on this Component. Can be specified as a number (in which case all edges get the same margin) or a CSS string like '5 10 10 10'
Defaults to:
null
A configuration to allow you to mask this container.
If the value is a string, it will be used as the message config for an Ext.LoadMask.
For more precise control over the mask, you can optionally pass an object block with
and xtype of loadmask, and an optional message value to display a loading mask.
Please refer to the Ext.LoadMask component to see other configurations.
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:

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
Minimum width of all buttonToolbar buttons in pixels. If set, this will be used as the default value for the Ext.Button#minWidth config of each Button added to the `buttonToolbar via the buttons toolbar.
It will be ignored for buttons that have a minWidth configured some other
way, e.g. in their own config object or via the
defaults of their parent container.
Defaults to:

true to make this Component modal. This will create a mask underneath the
Component that covers its parent and does not allow the user to interact with
any other Components until this Component is dismissed.
Defaults to:
null
This config enables binding to your Ext.data.Model#validators. This
is only processed by form fields (e.g., Ext.field.*) at present, however, this
setting is inherited and so can be set on a parent container.
When set to true by a component (or by an ancestor container), the validators
of for any {@Ext.data.Model record} fields will be used wherever the value is
bound to such data fields.
While this config can be set arbitrarily high in the component hierarchy, doing
so can create a lot overhead if most of your form fields do not actually rely on
validators in your data model.
Using this setting for a form that is bound to an Ext.data.Model might look
like this:
{
xtype: 'panel',
modelValidation: true,
items: [{
xtype: 'textfield',
bind: '{theUser.firstName}'
},{
xtype: 'textfield',
bind: '{theUser.lastName}'
},{
xtype: 'textfield',
bind: '{theUser.phoneNumber}'
},{
xtype: 'textfield',
bind: '{theUser.email}'
}]
}
Defaults to:

If this is enabled the form will automatically detect the need to use 'multipart/form-data' during submission.
Defaults to:
true
If this is enabled the form will automatically detect the need to use 'multipart/form-data' during submission.

retrieved using the lookupName method.
Defaults to:
true
Forms can be assigned names to be used in parent forms. Forms can be assigned names to be used in parent forms.
Defaults to:
true
The padding to use on this Component. Can be specified as a number (in which case all edges get the same padding) or a CSS string like '5 10 10 10'
Defaults to:
null
A list of params to be executed server side. Only used for the api 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
}]
});
Convenience config. Short for 'Right Bar' (right-docked, vertical toolbar).

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
The rendered flag is set when a widget is inserted into the document for the first time.
Note that this is a one-way operation. The first time a widget is inserted into the document, this flag is set, and it is never unset.
When true, FocusableContainer
will reset last focused position whenever focus leaves the container.
Subsequent tabbing into the container will always focus the first eligible
child item.
When false, subsequent tabbing into the container will focus the child
item that was last focused before.
Defaults to:
false
A configuration for a Ext.panel.Resizer.
Defaults to:
null
Available since: 6.5.0
The absolute right position of this Component; must be a valid CSS length value,
e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component
become 'positioned', which means it will no longer participate in the layout of the
Container that it resides in.
Defaults to:
null
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
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
This object contains config objects for the standard buttons (such as OK
and Cancel). This object is keyed by the itemId for the button and
contains the text and a default weight for
weighted containers to use. These default
weights vary by OS to provide the user with a button order that is consistent
for their platform. In particular, Windows and Linux (or rather all platforms
other then Mac OS and iOS) present the OK button followed by Cancel while
Mac OS and iOS present them in reverse order of 'Cancelfollowed byOK`.
The standard buttons, in weight order, are as follows:
okabortretryignoreyesnocancelapplysavesubmithelpcloseOn Mac OS and iOS this order is reversed with the exception of help which
is the first button. The buttons are assigned weights from 10 to 200.
Defaults to:
{
ok: {
text: 'OK',
weight: isMacOrAndroid ? 120 : 10
},
abort: {
text: 'Abort',
weight: isMacOrAndroid ? 110 : 20

Whether or not we want to perform a standard form submit.
Defaults to:
false
The unique id for this object to use for state management purposes.
Defaults to:
null
This config specifies the config properties that will be persisted using the
Ext.state.Provider. If this config is set to true, the
configs specified by statefulDefaults will be assumed.
stateful: true
Otherwise, this config can be an array of strings of the properties to save:
stateful: [
'width',
'height',
'collapsed'
]
The above is equivalent to:
stateful: {
width: true,
height: true,
collapsed: true
}
Note: To be truly stateful, an id or stateId must also be assigned.
A stateful object will save its state when any of these config properties change value.
Defaults to:
false
The default set of stateful properties. The form of this config is the same as stateful except this config cannot be a Boolean.
This config is intended for classes to specify so that instances can simply
enable statefulness using stateful: true.
Defaults to:
null
Additional CSS styles that will be rendered into an inline style attribute when the widget is rendered.
You can pass either a string syntax:
style: 'background:red'
Or by using an object:
style: {
background: 'red'
}
When using the object syntax, you can define CSS Properties by using a string:
style: {
'border-left': '1px solid red'
}
Although the object syntax is much easier to read, we suggest you to use the string syntax for better performance.
Defaults to:
null
When this is set to true, the form will automatically submit itself whenever
the action event fires on a field in this form. The action event usually fires
whenever you press go or enter inside a textfield.
Defaults to:
false
When this is set to true, the form will automatically submit itself whenever the action

The title text or config object for the Ext.panel.Title component.
Defaults to:
null
The alignment of the title text within the available space between the icon and the tools.
Defaults to:
'left'
true to allow expanding and collapsing the panel (when collapsible = true)
by clicking anywhere in the header bar, false to allow it only by clicking to tool

Defaults to:
null
Available since: 7.0
The name of the reference element to use as the "anchor" for the tool zones. The start zone is inserted just prior to the anchor element and the tail and end zones are inserted immediately after.
Not applicable for Ext.Container instances as they use docked items to create the tool zones
Defaults to:
'bodyElement'
The properties of this object are shallow copied (via applyIf()
as opposed to Ext.merge() to each tool declared in the tools
config.
Defaults to:
{
xtype: 'tool',
zone: 'end'
}
An array of Ext.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 ToolTip config object.
The default behavior is to use a shared tip instance. The tooltip configuration is registered with the Ext.tip.Manager. To enable this, your application can set the Ext.app.Application#quickTips config, or an instance of the Ext.tip.Manager may be created manually.
To force a unique tooltip instance to be created, specify autoCreate: true on this
configuration.
Configuring this with autoHide: false implies autoCreate: true so that the desired
persistent behavior can be obtained with other targets still showing the singleton
instance.
Defaults to:
null
The absolute top position of this Component; must be a valid CSS length value,
e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component
become 'positioned', which means it will no longer participate in the layout of the
Container that it resides in.
Defaults to:
null
Emulates the behavior of the CSS touch-action property in a cross-browser compatible manner.
Keys in this object are touch action names, and values are false to disable
a touch action or true to enable it. Accepted keys are:
panXpanYpinchZoomdoubleTapZoomAll touch actions are enabled (true) by default, so it is usually only necessary
to specify which touch actions to disable. For example, the following disables
only horizontal scrolling and pinch-to-zoom on the component's main element:
touchAction: {
panX: false,
pinchZoom: false
}
Touch actions can be specified on reference elements using the reference element name, for example:
// disables horizontal scrolling on the main element, and double-tap-zoom
// on the child element named "body"
touchAction: {
panY: false
body: {
doubleTapZoom: false
}
}
The primary motivation for setting the touch-action of an element is to prevent the browser's default handling of a gesture such as pinch-to-zoom, or drag-to-scroll, so that the application can implement its own handling of that gesture on the element. Suppose, for example, a component has a custom drag handler on its element and wishes to prevent horizontal scrolling of its container while it is being dragged:
Ext.create('Ext.Widget', {
touchAction: {
panX: false
},
listeners: {
drag: function(e) {
// implement drag logic
}
}
});
Defaults to:
null
A String, Ext.Template, Ext.XTemplate or an Array of strings to form an Ext.XTemplate. Used in conjunction with the data and tplWriteMode configurations.
Note The data configuration must be set for any content to be shown in the component when using this configuration.
Defaults to:
null
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
If set to true, reset() resets to the last loaded or setValues() data instead of when the form was first created.
Defaults to:
false
The ui or uis to be used on this Component
When a ui is configured, CSS class names are added to the element, created by appending the ui name(s) to each classCls and/or baseCls.
Defaults to:
null
One or more CSS classes to add to the component's primary element. This config is intended solely for use by the component instantiator (the "user"), not by derived classes.
For example:
items: [{
xtype: 'button',
userCls: 'my-button'
...
}]
Defaults to:
null
Set to true to allow users to select text within this component.
Can also be any valid value for the CSS3 user-select property.
A value of true implies auto, while false implies none.
May also be an object keyed by child element name.
By default, the user cannot click+drag+select text/elements of the UI. Applications may want to enable user selection for specific DOM elements, such as the bodyElement of a component used as a tab panel. The tab and tab text would not be user selectable in this example, but the content area when the tab is selected would.
userSelectable: {
element: true, // allow the element to be user selectable
bodyElement: true // allow the component's body element to be user selectable
}
Defaults to:
false
Available since: 6.5.1
Defaults to:
{
"true": Ext.baseCSSPrefix + 'user-selectable-auto',
"false": Ext.baseCSSPrefix + 'user-selectable-none',
all: Ext.baseCSSPrefix + 'user-selectable-all',
auto: Ext.baseCSSPrefix + 'user-selectable-auto',
text: Ext.baseCSSPrefix + 'user-selectable-text',
none: Ext.baseCSSPrefix + 'user-selectable-none'
}
This value controls this item's order in a weighted Container (see parent).
Lower values gravitate towards the start of the container - the top in vertical layouts, the locale start side in horizontal layouts.
Defaults to:
0
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
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.
This method is called before destroy to ensure that this instance's stateful
properties are saved to persistent storage. Since this object is about to be
destroyed, this cannot be delayed.
Returns the state id for this object.
The stateId or the configured id.
Adds one or more Components to this Container. Example:
var myPanel = Ext.create({
xtype: 'panel',
html : 'This will be added to a Container'
});
var items = myContainer.add([myPanel]); // Array returned
var item = myContainer.add(myPanel); // One item is returned
newItems : Object/Object[]/Ext.Component/Ext.Component[]
The new item(s) to add to the Container. Note that if an array of items to add was passed in, an array of added items will be returned as well even if there was only one item.
The Component(s) that were added.
Adds a CSS class to the body element. If not rendered, the class will be added when the panel is rendered.
cls : String
The class to add
this
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 arguments to pass to the handler function. Any additional arguments passed to fireEvent will be appended to these arguments.
destroyable : Boolean (optional)
When specified as true, the function returns a destroyable object. An object
which implements the destroy method which removes all listeners added in this call.
This syntax can be a helpful shortcut to using un; particularly when
removing multiple listeners. NOTE - not compatible when using the element
option. See un for the proper syntax for removing listeners added using the
element config.
Defaults to:
false
priority : Number (optional)
An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.
order : String (optional)
A legacy option that is provided for backward compatibility.
It is recommended to use the priority option instead. Available options are:
'before': equal to a priority of 100'current': equal to a priority of 0 or default priority'after': equal to a priority of -100Defaults to:
'current'
order : String (optional)
A shortcut for the order event option. Provided for backward compatibility.
Please use the priority event option instead.
Combining Options
Using the options argument, it is possible to combine different types of listeners:
A delayed, one-time listener.
myPanel.on('hide', this.handleClick, this, {
single: true,
delay: 100
});
Attaching multiple handlers in 1 call
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers and handler configs.
grid.on({
itemclick: 'onItemClick',
itemcontextmenu: grid.onItemContextmenu,
destroy: {
fn: function () {
// function called within the 'altCmp' scope instead of grid
},
scope: altCmp // unique scope for the destroy handler
},
scope: grid // default scope - provided for example clarity
});
Delegate
This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example:
var panel = Ext.create({
xtype: 'panel',
renderTo: document.body,
title: 'Delegate Handler Example',
frame: true,
height: 220,
width: 220,
html: '<h1 class="myTitle">BODY TITLE</h1>Body content'
});
// The click handler will only be called when the click occurs on the
// delegate: h1.myTitle ("h1" tag with class "myTitle")
panel.on({
click: function (e) {
console.log(e.getTarget().innerHTML);
},
element: 'body',
delegate: 'h1.myTitle'
});
Defaults to: 'current'
Only when the destroyable option is specified.
A Destroyable object. An object which implements the destroy method which removes
all listeners added in this call. For example:
this.btnListeners = = myButton.on({
destroyable: true
mouseover: function() { console.log('mouseover'); },
mouseout: function() { console.log('mouseout'); },
click: function() { console.log('click'); }
});
And when those listeners need to be removed:
Ext.destroy(this.btnListeners);
or
this.btnListeners.destroy();
The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.
Example:
Ext.define('Foo', {
extend: 'Ext.Component',
initComponent: function () {
this.addManagedListener(MyApp.SomeGlobalSharedMenu, 'show', this.doSomething);
this.callParent();
}
});
As you can see, when an instance of Foo is destroyed, it ensures that the 'show'
listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.
As of version 5.1 it is no longer necessary to use this method in most cases because
listeners are automatically managed if the scope object provided to
addListener is an Observable instance.
However, if the observable instance and scope are not the same object you
still need to use mon or addManagedListener if you want the listener to be
managed.
item : Ext.util.Observable/Ext.dom.Element
The item to which to add a listener/listeners.
ename : Object/String
The event name, or an object containing event name properties.
fn : Function/String (optional)
If the ename parameter was an event
name, this is the handler function or the name of a method on the specified
scope.
scope : Object (optional)
If the ename parameter was an event name, this is the scope (this reference)
in which the handler function is executed.
options : Object (optional)
If the ename parameter was an event name, this is the
addListener options.
Only when the destroyable option is specified.
A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:
this.btnListeners = myButton.mon({
destroyable: true
mouseover: function() { console.log('mouseover'); },
mouseout: function() { console.log('mouseout'); },
click: function() { console.log('click'); }
});
And when those listeners need to be removed:
Ext.destroy(this.btnListeners);
or
this.btnListeners.destroy();
Adds a plugin. For example:
list.addPlugin('pullrefresh');
Or:
list.addPlugin({
type: 'pullrefresh',
pullRefreshText: 'Pull to refresh...'
});

handler: function () {
// ....
}
});
panel.addTool([{
type: 'gear',
handler: 'viewControllerGearMethod'
}, {
type: 'save',
handler: 'viewControllerSaveMethod'
}]);
By default the tools will be accessible via keyboard, with the exception of automatically added collapse/expand and close tools.
If you implement keyboard equivalents of your tools' actions elsewhere and do not want the tools to participate in keyboard navigation, you can make them presentational instead:
panel.addTool({
type: 'mytool',
focusable: false,
ariaRole: 'presentation'
// ...
});
tool : Object/Object[]/Ext.Tool/Ext.Tool[]
The tool or tools to add.

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
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)

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[]

A promise that resolves when the expand completes.
Called when an item is added to this container either during initialization of the cfg-items config, or when new items are {@link #method!add added), or inserted.
If the passed object is not an instanced component, it converts the passed object into an instanced child component.
It applies cfg-defaults applied for contained child items - that is items which are not positiond using left, top, bottom, right, centered or docked.
Derived classes can override this method to process context appropriate short-hands such as Toolbar and "->" to insert a spacer.
item : Mixed

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.
Try to focus this component.
If this component is disabled or otherwise not focusable, a close relation will be targeted for focus instead to keep focus localized for keyboard users.
selectText : Boolean/Number[] (optional)
If applicable, true to also select all the text
in this component, or an array consisting of start and end (defaults to start)
position of selection.

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

Similar to getRenderTarget but for positioned items.
Available since: 6.5.0
item : Ext.Component
The positioned item being added.
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
Returns an object holding the descendants of this view keyed by their
reference. This object should not be held
past the scope of the function calling this method. It will not be valid if items
are added or removed from this or any sub-container.
The intended usage is shown here (assume there are 3 components with reference values of "foo", "bar" and "baz" at some level below this container):
onClick: function () {
var refs = this.getReferences();
// using "refs" we can access any descendant by its "reference"
refs.foo.getValue() + refs.bar.getValue() + refs.baz.getValue();
}
If this component has a reference assigned
to it, that is not included in this object. That reference is understood to
belong to the ancestor container configured as the referenceHolder.
Available since: 5.0.0
An object with each child reference. This will be null if this
container has no descendants with a reference
specified.
Returns the element into which the html content and items should be rendered.
This defaults to the bodyElement but derived classes can override this method
to use a different element.
For containers his only applies to inner items, not docked items. The
positioned items are rendered to the element returned by the
{@link Ext.Container#getPositionedItemTarget method.
Available since: 6.5.0
This method is required by the Scroller to return the scrollable client region
The scrolling viewport region.
Creates a state builder to access or edit this instance's state object. If this
instance has a getStatefulOwner, the returned
builder will have a parent reference that owner's state builder. This can be
an arbitrarily deep chain but does proceed all the way up to the root instance
(with no owner) since that is the instance that determines the ultimate state
storage key.
cache : Boolean (optional)
Pass true to return a cached builder.
Defaults to: false
This method allows a class to specify an owning stateful object. This is used by Ext.plugin.Abstract to save their state as part of their owning Ext.Component.
The return value can be either a Stateful object or an array whose first element is
a Stateful object. This object's state will be stored inside the state object of
the returned Stateful object. If an array is returned, the elements beyond the first
are sub-keys in the state object.
For example, Ext.plugin.Abstract implement this method like so:
getStatefulOwner: function() {
return [ this.cmp, 'plugins' ];
}
The effect of this is to produce a state object like so:
{
plugins: {
pluginId1: {
//...
}
}
}
In order for a child object's state to be saved and restored, all of its parents must
also be stateful (i.e., have a stateId).
Return the actual tabIndex for this Focusable.
tabIndex attribute value
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.
eventName : String
The name of the event to check for
true if the event is being listened for or bubbles, else false
Returns true if this component has a parent.
true if this component has a parent.
Hides this Component optionally using an animation.
animation : Object/Boolean (optional)
You can specify an animation here or a bool to use the hideAnimation config.

index : Number
The index to insert the Component at.
item : Object
The Component to insert.
Selector processing function for use by nextSibling,previousibling, nextNode,and previousNode, to filter candidate nodes.
The base implementation returns true. Classes which mix in Traversable may implement
their own implementations. @link{Ext.Widget} does this to implement
Ext.ComponentQuery based filterability.
This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

Determine if this Focusable can receive focus at this time.
Note that Containers can be non-focusable themselves while delegating focus treatment to a child Component; see Container for more information.
deep : Boolean (optional)
Optionally determine if the container itself is focusable, or if container's focus is delegated to a child component and that child is focusable.
Defaults to: false
True if component is focusable, false if not.
Checks if all events, or a specific event, is suspended.
event : String (optional)
The name of the specific event to check
true if events are suspended
Test to see if the form has any invalid fields.
NOTE This method does not validate the fields, it only returns
true if any field is already marked invalid using the field's
isValid. If field values need to
be validated, validate should be used instead.
true if all fields are currently valid.
Performs an Ajax or Ext Direct call to load values for this form.
options : Object
The configuration when loading this form.
The following are the configurations when loading via Ajax only:

Request headers to set for the action.
timeout : Number
The number is seconds the loading will timeout in.
The following are the configurations when loading via Ajax or Direct:
autoAbort : Boolean (optional)
true to abort any pending Ajax request prior to loading.
Defaults to:
false
The params to pass when submitting this form (defaults to baseParams). Parameters are encoded as standard HTTP parameters using Ext#urlEncode.
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 loading via Ajax or Direct:
form : Ext.form.Panel
The FormPanel that requested the load.
result : Object/Ext.direct.Event

The callback that will be invoked after a failed transaction attempt.
The function is passed the following parameters and can be used for loading via Ajax or Direct:
form : Ext.form.Panel
The FormPanel that requested the load.
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).

This method is called to load state from the provided state builder. This method
should return the config properties loaded from state.
This method, like saveState, can be overridden by derived classes:
loadState: function(state) {
var ret = this.callParent([ state ]);
if (ret.foo) {
// use custom data...
delete ret.foo; // remove it since it isn't a config
}
return ret;
}
When overriding this method, it is also likely necessary to override saveState.
state : Ext.state.Builder
stateful : Object
The stateful properties as an object keyed by config name.
Gets a reference to the component with the specified reference value.
The method is a short-hand for the lookupReference method.
Available since: 6.0.1

Gets a reference to the component with the specified name property.
Available since: 6.5.0
name : String
The name of the descendant to lookup.
The component or null if it is not found.
Gets a reference to the component with the specified reference value.

The referenced component or null if it is not found.
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.

The next node (or the next node which matches the selector).
Returns null if there is no matching node.
Returns the next sibling of this Component.

May also be referred to as next()
Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with
nextNode
selector : String (optional)
A Ext.ComponentQuery selector to filter the following items.
The next sibling (or the next sibling which matches the selector).
Returns null if there is no matching sibling.
The on method is shorthand for addListener.
Appends an event handler to this object. For example:
myGridPanel.on("itemclick", this.onItemClick, this);
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:
myGridPanel.on({
cellclick: this.onCellClick,
select: this.onSelect,
viewready: this.onViewReady,
scope: this // Important. Ensure "this" is correct during handler execution
});
One can also specify options for each event handler separately:
myGridPanel.on({
cellclick: {fn: this.onCellClick, scope: this, single: true},
viewready: {fn: panel.onViewReady, scope: panel}
});
Names of methods in a specified scope may also be used:
myGridPanel.on({
cellclick: {fn: 'onCellClick', scope: this, single: true},
viewready: {fn: 'onViewReady', scope: panel}
});

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 arguments to pass to the handler function. Any additional arguments passed to fireEvent will be appended to these 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();

Saves the state of this instance to the persistence store. This method is called by the Ext.state.Provider when it is ready to save state to storage.
This is the private method to ensure everything is set up for showing. This is called by both show and showBy to set a component up. the user-facing method is beforeShow, this setup must have happened by the time that is called.
component : Object
alignment : Object
options : Object
Returns the previous node in the Component tree in tree traversal order.
Note that this is not limited to siblings, and if invoked upon a node with no matching siblings, will walk the tree in reverse order to attempt to find a match. Contrast with previousSibling.
selector : String (optional)
A Ext.ComponentQuery selector to filter the preceding nodes.
The previous node (or the previous node which matches the selector).
Returns null if there is no matching node.
Returns the previous sibling of this Component.
Optionally selects the previous sibling which matches the passed Ext.ComponentQuery selector.
May also be referred to as prev()
Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with
previousNode
selector : String (optional)
A Ext.ComponentQuery selector to filter the preceding items.
The previous sibling (or the previous sibling which matches the selector).
Returns null if there is no matching sibling.
Retrieves all descendant components which match the passed selector. Executes an Ext.ComponentQuery.query using this container as its root.
selector : String (optional)

scope : Object (optional)
The scope in which to run the function. If not specified, it will default to the active component.
Components matched by the passed function
Finds a component at any level under this container matching the id/itemId. This is a shorthand for calling ct.down('#' + id);
id : String
The id to find
The matching id, null if not found
Returns this instance's state object from the persistence store. This object should contain config properties.
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();

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

its owning container's layout.
Deprecated since version 6.2
Use resetPositioned instead.
Resets top, right, bottom and left configurations to
null, which will cause this component to stop being 'positioned' and to take its place in
its owning container's layout.
Resumes firing of the named event(s).
After calling this method to resume events, the events will fire when requested to fire.
Note that if the suspendEvent method is called multiple times for a certain event, this converse method will have to be called the same number of times for it to resume firing.
eventName : String...
Multiple event names to resume.
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.
discardQueue : Boolean (optional)
true to prevent any previously queued events from firing
while we were suspended. See suspendEvents.
Saves the current state of this object to the provided state builder. By default
this method saves the configs specified as stateful.
This method can also be overridden by subclasses to store custom data directly to
the state builder:
saveState: function(state) {
this.callParent([ state ]);
state.set('foo', 42);
}
When overriding this method, it is also likely necessary to override loadState.
state : Ext.state.Builder
The state builder to which to save state.
stateful : Object
The stateful properties as an object keyed by config name.
Marks multiple fields valid or invalid based upon an Object of error states
Each key of the error states Object is the name of the field whose validity status is to be affected. Each value of the error states Object is either a string or array of strings to set as the field's invalid message(s). If the value is null or an empty array, the field is marked valid instead of invalid.
errors : Object
The errors to set child fields with.
this
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
Set the tabIndex property for this Focusable. If the focusEl is available, set tabIndex attribute on it, too.
newTabIndex : Number
new tabIndex to set
Sets the values of form fields in bulk. Example usage:

username: 'edspencer'
});
If there groups of checkbox fields with the same name, pass their values in an array. For example:
myForm.setValues({
name: 'Jacky',
crazy: false,
hobbies: [
'reading',
'cooking',
'gaming'
]
});
values : Object
field name => value mapping object.
This form.
This method has the same arguments as element's setXY
method, but is used to maintain the x and y configs (for floated components)
or the left and top config for positioned components.

x : Object
y : Object
animation : Object
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.
Displays component at specific xy position. A floating component (like a menu) is positioned relative to its ownerCt if any. Useful for popping up a context menu:
listeners: {
itemcontextmenu: function(view, record, item, index, event, options) {
Ext.create('Ext.menu.Menu', {
width: 100,
height: 100,
margin: '0 0 10 0',
items: [{
text: 'regular item 1'
},{
text: 'regular item 2'
},{
text: 'regular item 3'
}]
}).showAt(event.getXY());
}
}
x : Number/Number[]/Object
The new x position or array of [x,y], or an
object {x:10, y:10}.
y : Number (optional)
The new y position.
this
Shows this component by another component. If you specify no alignment, it will automatically
position this component relative to the reference component depending upon the alignment
parameter.
The alignment parameter describes the edge-to-edge alignment of this component
with the target. It can be specified thus:
'l-r?',
'r-l?', 'b-t?' then 't-b?' in that order.t/r/b/l) followed by a percentage along that side. This describes a
point to align with a similar point in the target. So 't0-b0' would be
the same as 'tl-bl', 'l0-r50' would place the top left corner of this item
halfway down the right edge of the target item. This allows more flexibility
and also describes which two edges are considered adjacent when positioning a tip pointer.Following are all of the supported predefined anchor positions:
Value Description
----- -----------------------------
tl The top left corner
t The center of the top edge
tr The top right corner
l The center of the left edge
c The center
r The center of the right edge
bl The bottom left corner
b The center of the bottom edge
br The bottom right corner
You can put a '?' at the end of the alignment string to constrain the positioned element to the Ext.Viewport. The element will attempt to align as specified, but the position will be adjusted to constrain to the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than that specified in order to enforce the viewport constraints.
Example Usage:
// 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");
// align the center of panel with the bottom left corner of button and
// adjust the x position by -6 pixels (and the y position by 0)
panel.showBy(button, "c-bl", [-6, 0]);
// align the 25% point on the bottom edge of this panel
// with the 75% point on the top edge of button.
panel.showBy(button, 'b25-t75');

A set of arguments to be appended to the function's argument list to pass down extra data known to the caller after the node being visited.
Traverses the tree rooted at this node in pre-order mode, calling the passed function on the nodes at each level. That is the function is called upon each node before being called on its children).
This method is used at each level down the cascade. Currently Ext.Components and Ext.data.TreeModels are queryable.
If you have tree-structured data, you can make your nodes queryable, and use ComponentQuery on them.
selector : Object
A ComponentQuery selector used to filter candidate nodes before calling the function. An empty string matches any node.
fn : Function
The function to call. Return false to aborl the traverse.
node : Object
The node being visited.
scope : Object (optional)
The context (this reference) in which the function is executed.
extraArgs : Array (optional)
A set of arguments to be appended to the function's argument list to pass down extra data known to the caller after the node being visited.
Queue a function to run when the component is visible & painted. If those conditions are met, the function will execute immediately, otherwise it will wait until it is visible and painted.
fn : String
The function to execute on this component.
args : Object[] (optional)
The arguments to pass.
true if the function was executed immediately.
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).
