Ext.pivot.plugin.configurator.Container xtype: pivotconfigcontainer premium

activeItem : Object / String / Number

bindable bind

The item from the cfg-items collection that will be active first. This is usually only meaningful in a Ext.layout.Card, where only one item can be active at a time. If passes a string, it will be assumed to be a Ext.ComponentQuery selector.

Defaults to:

0

allowDeselect : Boolean

bindable bind

Allow users to deselect a record in a DataView, List or Grid. Only applicable when the Selectable's mode is 'SINGLE'.

Defaults to:

false

alwaysOnTop : Boolean / Number

bindable bind

A flag indicating that this component should be above its floated siblings.

This may be a positive number to prioritize the ordering of multiple visible always on top components.

This may be set to a negative number to prioritize a component to the bottom of the z-index stack.

Defaults to:

false

Available since: 6.2.0

autoDestroy : Boolean

bindable bind

If true, child items will be destroyed as soon as they are removed from this container.

Defaults to:

true

axisLock : Boolean

bindable bind

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

bind : Object / String

bindable bind

Setting this config option adds or removes data bindings for other configs. For example, to bind the title config:

 var panel = Ext.create({
     xtype: 'panel',
     bind: {
         title: 'Hello {user.name}'
     }
 });

To dynamically add bindings:

 panel.setBind({
     title: 'Greetings {user.name}!'
 });

To remove bindings:

 panel.setBind({
     title: null
 });

The bind expressions are presented to Ext.app.ViewModel#bind. The ViewModel instance is determined by lookupViewModel.

Note: If bind is passed as a string, it will use the Ext.Component#property-defaultBindProperty for the binding.

Defaults to:

null

border : Boolean

bindable bind

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).

Using style:

Ext.Viewport.add({
    centered: true,
    width: 100,
    height: 100,

    style: 'border: 1px solid blue;'
    // ...
});

Using CSS:

Ext.Viewport.add({
    centered: true,
    width: 100,
    height: 100,

    cls: 'my-component'
    // ...
});

And your CSS file:

.my-component {
    border: 1px solid red;
}

Defaults to:

null

bottom : Number / String

bindable bind

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

bufferSize : Number

bindable bind

The amount of items we render additionally besides the ones currently visible. We try to prevent the rendering of items while scrolling until the next time you stop scrolling. If you scroll close to the end of the buffer, we start rendering individual items to always have the minimumBufferSize prepared.

Defaults to:

20

centered : Boolean

bindable bind

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

cls : String / String[]

bindable bind

The CSS class to add to this widget's element, in addition to the baseCls. In many cases, this property will be specified by the derived widget class. See userCls for adding additional CSS classes to widget instances (such as items in a Ext.Container).

Defaults to:

null

constrainTo : Ext.dom.Element / Ext.util.Region

bindable bind

The element into which floated or positioned items constrain their position.

Defaults to the parent container for positioned components, and to the viewport for floated components.

Defaults to:

null

container : Object

bindable bind

This config is used to control the internal Ext.Container created to manage this list's items. One common use for this is to apply a userCls to the item container.

 {
     xtype: 'list',
     container: {
         userCls: 'mylist-cls'
     },
     ...
 }

Defaults to:

{
    xtype: 'container',
    scrollable: {}
}

Available since: 6.0.1

contentEl : Ext.dom.Element / HTMLElement / String

bindable bind

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

control : Object

bindable bind

Enables you to easily control Components inside this Container by listening to their events and taking some action. For example, if we had a container with a nested Disable button, and we wanted to hide the Container when the Disable button is tapped, we could do this:

Ext.create('Ext.Container', {
    control: {
       'button[text=Disable]': {
           tap: 'hideMe'
       }
    },

    hideMe: function () {
        this.hide();
    }
});

We used a Ext.ComponentQuery selector to listen to the tap event on any Ext.Button anywhere inside the Container that has the text 'Disable'. Whenever a Component matching that selector fires the tap event our hideMe function is called. hideMe is called with scope: this (e.g. this is the Container instance).

Defaults to:

null

controller : String / Object / Ext.app.ViewController

bindable bind

A string alias, a configuration object or an instance of a ViewController for this container. Sample usage:

Ext.define('MyApp.UserController', {
    alias: 'controller.user'
});

Ext.define('UserContainer', {
    extend: 'Ext.container.container',
    controller: 'user'
});
// Or
Ext.define('UserContainer', {
    extend: 'Ext.container.container',
    controller: {
        type: 'user',
        someConfig: true
    }
});

// Can also instance at runtime
var ctrl = new MyApp.UserController();
var view = new UserContainer({
    controller: ctrl
});

Defaults to:

null

data : Object[]

bindable bind

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

defaultListenerScope : Boolean

bindable bind

If true, this component will be the default scope (this pointer) for events specified with string names so that the scope can be dynamically resolved. The component will automatically become the defaultListenerScope if a controller is specified.

See the introductory docs for Ext.container.Container for some sample usages.

NOTE: This value can only be reliably set at construction time. Setting it after that time may not correctly rewire all of the potentially effected listeners.

Defaults to:

false

defaults : Object

bindable bind

A set of default configurations to apply to all child Components in this Container. It's often useful to specify defaults when creating more than one items with similar configurations. For example here we can specify that each child is a panel and avoid repeating the xtype declaration for each one:

Ext.create('Ext.Container', {
    defaults: {
        xtype: 'panel'
    },
    items: [
        {
            html: 'Panel 1'
        },
        {
            html: 'Panel 2'
        }
    ]
});

Defaults to:

null

defaultType : String

bindable bind

The xtype used for the component based DataView. Defaults to dataitem. Note this is only used when useComponents is true.

Defaults to:

undefined

deferEmptyText : Boolean

bindable bind

true to defer emptyText being applied until the store's first load.

Defaults to:

true

deselectOnContainerClick : Boolean

bindable bind

When set to true, tapping on the DataView's background (i.e. not on an item in the DataView) will deselect any currently selected items.

Defaults to:

true

disabled : Boolean

bindable bind

Whether or not this component is disabled

Defaults to:

null

disableSelection : Boolean

bindable bind

true to disable selection. This configuration will lock the selection model that the DataView uses.

Defaults to:

null

disclosureProperty : String

bindable bind

A property to check on each record to display the disclosure on a per record basis. This property must be false to prevent the disclosure from being displayed on the item.

Defaults to:

'disclosure'

docked : String

bindable bind

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

draggable : Object

bindable bind

Configuration options to make this Component draggable

Defaults to:

null

emptyText : String

bindable bind

The text to display in the view when there is no data to display

Defaults to:

null

flex : Number

bindable bind

The flex of this item if this item item is inside a Ext.layout.HBox or Ext.layout.VBox layout.

You can also update the flex of a component dynamically using the Ext.layout.FlexBox#setItemFlex method.

Defaults to:

null

floated : Boolean

bindable bind

A Component may be floated above all other components in the application. This means that the component is absolutely positioned, and will move to the front and occlude other sibling floated component if clicked.

A Floated component may have floated descendants. It will bring these decendants to the front with it when brought to the front of its sibling floated components.

By default, descendant floated components are all positioned using the viewport coordinate system. To make a floating component a positioning parent for descendants, and have the ancestors positioned relatively, configure the parent floated component with cfg-relative: true.

Defaults to:

false

Available since: 6.2.0

fullscreen : Boolean

Force the component to take up 100% width and height available, by adding it to Ext.Viewport.

grouped : Boolean

bindable bind

Whether or not to group items in the provided Store with a header for each item.

Defaults to:

null

height : Number / String

bindable bind

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

hidden : Boolean

bindable bind

Whether or not this Component is hidden (its CSS display property is set to none).

Defaults to true for floated Components.

Defaults to:

null

hideAnimation : String / Mixed

bindable bind

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

hideOnMaskTap : Boolean

bindable bind

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

html : String / Ext.dom.Element / HTMLElement

bindable bind

Optional HTML content to render inside this Component, or a reference to an existing element on the page.

Defaults to:

null

id : String

The unique id of this component instance.

It should not be necessary to use this configuration except for singleton objects in your application. Components created with an id may be accessed globally using Ext.getCmp.

Instead of using assigned ids, use the itemId config, and Ext.ComponentQuery which provides selector-based searching for Sencha Components analogous to DOM querying. The Ext.Container class contains shortcut methods to query its descendant Components by selector.

Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent.

Note: to avoid complications imposed by a unique id also see itemId.

Defaults to an auto-assigned id.

indexBar : Boolean / Object

bindable bind

true to render an alphabet IndexBar docked on the right. This can also be a config object that will be passed to Ext.IndexBar.

Defaults to:

false

infinite : Boolean

bindable bind

Set this to false to render all items in this list, and render them relatively. Note that this configuration can not be dynamically changed after the list has instantiated.

Defaults to:

false

inline : Boolean / Object

bindable bind

When set to true the items within the DataView will have their display set to inline-block and be arranged horizontally. By default the items will wrap to the width of the DataView. Passing an object with { wrap: false } will turn off this wrapping behavior and overflowed items will need to be scrolled to horizontally.

Defaults to:

null

itemCls : String

bindable bind

An additional CSS class to apply to items within the DataView.

Defaults to:

null

itemHeight : Number

bindable bind

This allows you to set the default item height and is used to roughly calculate the amount of items needed to fill the list. By default items are around 50px high.

Defaults to:

null

itemId : String

bindable bind

An itemId can be used as an alternative way to get a reference to a component when no object reference is available. Instead of using an id with Ext#getCmp, use itemId with Ext.Container#getComponent which will retrieve itemId's or id's. Since itemId's are an index to the container's internal MixedCollection, the itemId is scoped locally to the container - avoiding potential conflicts with Ext.ComponentManager which requires a unique id.

Also see id, Ext.Container#query, Ext.Container#down and Ext.Container#child.

Defaults to:

undefined

items : Array / Object

bindable bind

The child items to add to this Container. This is usually an array of Component configurations or instances, for example:

Ext.create('Ext.Container', {
    items: [
        {
            xtype: 'panel',
            html: 'This is an item'
        }
    ]
});

Defaults to:

null

itemTpl : String / String[] / Ext.XTemplate

bindable bind

The tpl to use for each of the items displayed in this DataView.

Defaults to:

'<div>{text}</div>'

keyMap : Object

bindable bind

An object containing handlers for keyboard events. The property names of this object are the key name and any modifiers. The values of the properties are the descriptors of how to handle each event.

The handler descriptor can be simply the handler function (either the literal function or the method name), or it can be an object with these properties:

• handler: The function or its name to call to handle the event.
• scope: The this pointer context (can be "this" or "controller").
• event: An optional override of the key event to which to listen.

Important: Calls to setKeyMap do not replace the entire keyMap but instead update the provided mappings. That is, unless null is passed as the value of the keyMap which will clear the keyMap of all entries.

Defaults to:

null

Properties

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.

keyMapEnabled : Boolean

bindable bind

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

left : Number / String

bindable bind

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

listeners : Object

bindable bind

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'); }
        }
    }
});

loadingText : String / Boolean

bindable bind

A string to display during data load operations. If specified, this text will be displayed in a loading div and the view's contents will be cleared while loading, otherwise the view's contents will continue to display normally until the new data is loaded and the contents are replaced.

Defaults to:

'Loading...'

margin : Number / String

bindable bind

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

masked : Boolean / Object / Ext.Mask / Ext.LoadMask

bindable bind

A configuration to allow you to mask this container. You can optionally pass an object block with and xtype of loadmask, and an optional message value to display a loading mask. Please refer to the Ext.LoadMask component to see other configurations.

masked: {
    xtype: 'loadmask',
    message: 'My message'
}

Alternatively, you can just call the setter at any time with true/false to show/hide the mask:

setMasked(true); //show the mask
setMasked(false); //hides the mask

There are also two convenient methods, method-mask and unmask, to allow you to mask and unmask this container at any time.

Remember, the Ext.Viewport is always a container, so if you want to mask your whole application at anytime, can call:

Ext.Viewport.setMasked({
    xtype: 'loadmask',
    message: 'Hello'
});

Defaults to:

null

maxHeight : Number / String

bindable bind

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

maxWidth : Number / String

bindable bind

The maximum width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size. Note that this config will not apply if the Component is 'positioned' (absolutely positioned or centered)

Defaults to:

null

minHeight : Number / String

bindable bind

The minimum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size.

Defaults to:

null

minWidth : Number / String

bindable bind

The minimum width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size.

Defaults to:

null

modal : Boolean

bindable bind

true to make this Componenrt modal. This will create a mask underneath the Component that covers its parent and does not allow the user to interact with any other Components until this Component is dismissed.

Defaults to:

null

mode : String

bindable bind

Modes of selection. Valid values are 'SINGLE', 'SIMPLE', and 'MULTI'.

Defaults to:

'SINGLE'

onItemDisclosure : Boolean / Function / String / Object

bindable bind

true to display a disclosure icon on each list item. The list will still fire the disclose event, and the event can be stopped before itemtap. By setting this config to a function, the function passed will be called when the disclosure is tapped. Finally you can specify an object with a 'scope' and 'handler' property defined. This will also be bound to the tap event listener and is useful when you want to change the scope of the handler.

Defaults to:

null

padding : Number / String

bindable bind

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

pinHeaders : Boolean

bindable bind

Whether or not to pin headers on top of item groups while scrolling for an iPhone native list experience.

Defaults to:

true

pinnedHeader : Object

bindable bind

A config object for the pinned header. Only applicable when pinHeaders is true.

Defaults to:

{
    xtype: 'itemheader',
    pinned: true
}

plugins : Object / String / Object[] / String[]

bindable bind

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.

Example code

A plugin by alias:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: 'listpaging'
 });

Multiple plugins by alias:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: ['listpaging', 'pullrefresh']
 });

Single plugin by class name with config options:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: {
         type: 'listpaging',
         autoPaging: true
     }
 });

Multiple plugins by type and class name with config options:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: [{
         xclass: 'Ext.plugin.PullRefresh',
         pullRefreshText: 'Pull to refresh...'
     }, {
         type: 'listpaging',
         autoPaging: true
     }]
 });

Defaults to:

null

pressedDelay : Number

bindable bind

The amount of delay between the tapstart and the moment we add the pressedCls.

Settings this to true defaults to 100ms.

Defaults to:

100

preventSelectionOnDisclose : Boolean

bindable bind

true to prevent the item selection when the user taps a disclose icon.

Defaults to:

true

publishes : String / String[] / Object

bindable bind

One or more names of config properties that this component should publish to its ViewModel. Generally speaking, only properties defined in a class config block (including ancestor config blocks and mixins) are eligible for publishing to the viewModel. Some components override this and publish their most useful configs by default.

Note: We'll discuss publishing properties not found in the config block below.

Values determined to be invalid by component (often form fields and model validations) will not be published to the ViewModel.

This config uses the cfg-reference to determine the name of the data object to place in the ViewModel. If reference is not set then this config is ignored.

By using this config and cfg-reference you can bind configs between components. For example:

 ...
     items: [{
         xtype: 'textfield',
         reference: 'somefield',  // component's name in the ViewModel
         publishes: 'value' // value is not published by default
     },{
         ...
     },{
         xtype: 'displayfield',
         bind: 'You have entered "{somefield.value}"'
     }]
 ...

Classes must provide this config as an Object:

 Ext.define('App.foo.Bar', {
     publishes: {
         foo: true,
         bar: true
     }
 });

This is required for the config system to properly merge values from derived classes.

For instances this value can be specified as a value as show above or an array or object as follows:

 {
     xtype: 'textfield',
     reference: 'somefield',
     publishes: [
         'value',
         'rawValue',
         'dirty'
     ]
 }

 // This achieves the same result as the above array form.
 {
     xtype: 'textfield',
     reference: 'somefield',
     publishes: {
         value: true,
         rawValue: true,
         dirty: true
     }
 }

In some cases, users may want to publish a property to the viewModel that is not found in a class config block. In these situations, you may utilize publishState if the property has a setter method. Let's use setFieldLabel as an example:

  setFieldLabel: function(fieldLabel) {
      this.callParent(arguments);
      this.publishState('fieldLabel', fieldLabel);
  }

With the above chunk of code, fieldLabel may now be published to the viewModel.

Defaults to:

null

Available since: 5.0.0

record : Ext.data.Model

bindable bind

A model instance which updates the Component's html based on it's tpl. Similar to the data configuration, but tied to to a record to make allow dynamic updates. This must be a model instance and not a configuration of one.

Defaults to:

null

reference : String

bindable bind

Specifies a name for this component inside its component hierarchy. This name must be unique within its view or its Ext.app.ViewController. See the documentation in Ext.container.Container for more information about references.

Note: Valid identifiers start with a letter or underscore and are followed by zero or more additional letters, underscores or digits. References are case sensitive.

Defaults to:

null

referenceHolder : Boolean

bindable bind

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

refreshHeightOnUpdate : Boolean

bindable bind

Set this to false if you make many updates to your list (like in an interval), but updates won't affect the item's height. Doing this will increase the performance of these updates.

Defaults to:

true

relative : Boolean

bindable bind

Only valid when a component is cfg-floated

Configure this as true if you require descendant floated components to be positioned relative to this component's coordinate space, not the viewport's coordinate space.

Note: The coordinate space is this Component's encapsulating element's area. Not that of the inner element in which static child items are rendered by the layout.

Defaults to:

false

Available since: 6.2.0

renderTo : Ext.dom.Element

bindable bind

Optional element to render this Component to. Usually this is not needed because a Component is normally full screen or automatically rendered inside another Ext.Container

Defaults to:

null

right : Number / String

bindable bind

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

rowLines : Boolean

bindable bind

Set this to false to suppress the borders in between the items in this list. By default the presence of borders in between the items is determined by the stylesheet

Defaults to:

null

scrollDock : String

bindable bind

The dock position of a list's child items relative to the list itself. Can be top or bottom.

Ext.create('Ext.List', {
     fullscreen: true,
     itemTpl: '{firstName}',
     data: [
         { firstName: 'Peter'},
         { firstName: 'Raymond'},
         { firstName: 'Egon'},
         { firstName: 'Winston'}
     ],
     items: [{
          xtype: 'component',
          html: 'Docked!',
          docked: 'top'
     },{

          scrollDock: 'top'
     }]
 });

Defaults to:

null

scrollToTopOnRefresh : Boolean

bindable bind

Scroll the DataView to the top when the DataView is refreshed.

Defaults to:

true

selection : Ext.data.Model

bindable bind

The selected record.

Defaults to:

null

session : Boolean / Object / Ext.data.Session

bindable bind

If provided this creates a new Session instance for this component. If this is a Container, this will then be inherited by all child components.

To create a new session you can specify true:

 Ext.create({
     xtype: 'viewport',
     session: true,

     items: [{
         ...
     }]
 });

Alternatively, a config object can be provided:

 Ext.create({
     xtype: 'viewport',
     session: {
         ...
     },

     items: [{
         ...
     }]
 });

Defaults to:

null

shadow : Boolean

bindable bind

Configure as true for the component to have a drop shadow. 'false' will suppress any default shadow. By default the theme will determine the presence of a shadow.

Defaults to:

null

Available since: 6.2.0

shim : Boolean

bindable bind

Only valid when a component is cfg-floated

Configure as true for the component to use an <iframe> as an underlay to ensure certain non-standard browser plugins are occluded by this component.

Defaults to:

false

Available since: 6.2.0

showAnimation : String / Mixed

bindable bind

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

store : Ext.data.Store / Object

bindable bind

Can be either a Store instance or a configuration object that will be turned into a Store. The Store is used to populate the set of items that will be rendered in the DataView. See the DataView intro documentation for more information about the relationship between Store and DataView.

Defaults to:

null

striped : Boolean

bindable bind

Set this to true if you want the items in the list to be zebra striped, alternating their background color.

Defaults to:

false

style : String / Object

bindable bind

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

styleHtmlCls : String

bindable bind

The class that is added to the content target when you set styleHtmlContent to true.

Defaults to:

"x-html"

styleHtmlContent : Boolean

bindable bind

true to automatically style the HTML inside the content target of this component (body for panels).

Defaults to:

false

toFrontOnShow : Boolean

bindable bind

True to automatically call toFront when a cfg-floated Component is shown.

Defaults to:

true

tooltip : String / Object

bindable bind

The tooltip for this component - can be a string to be used as innerHTML (html tags are accepted) or Ext.tip.ToolTip config object.

The default behavior is to use a shared tip instance. The tooltip configuration is registered with the Ext.tip.Manager. To enable this, your application can set the Ext.app.Application#quickTips config, or an instance of the Ext.tip.Manager may be created manually.

To force a unique tooltip instance to be created, specify autoCreate: true on this configuration.

Configuring this with autoHide: false implies autoCreate: true so that the desired persistent behavior can be obtained with other targets still showing the singleton instance.

Defaults to:

null

top : Number / String

bindable bind

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

touchAction : Object

bindable bind

Emulates the behavior of the CSS href="https://www.w3.org/TR/pointerevents/#the-touch-action-css-property" class="external-link" target="_blank">https://www.w3.org/TR/pointerevents/#the-touch-action-css-property touch-action property in a cross-browser compatible manner.

Keys in this object are touch action names, and values are false to disable a touch action or true to enable it. Accepted keys are:

• panX
• panY
• pinchZoom
• doubleTapZoom

All 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

tpl : String / String[] / Ext.Template / Ext.XTemplate[]

bindable bind

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

tplWriteMode : String

bindable bind

The Ext.(X)Template method to use when updating the content area of the Component. Valid modes are:

• append
• insertAfter
• insertBefore
• insertFirst
• overwrite

Defaults to:

'overwrite'

triggerCtEvent : String

bindable bind

Determines what type of touch event is recognized as a touch on the container. Valid options are 'tap' and 'singletap'.

Defaults to:

'tap'

triggerEvent : String

bindable bind

Determines what type of touch event causes an item to be selected. Valid options are: 'itemtap', 'itemsingletap', 'itemdoubletap', 'itemswipe', 'itemtaphold'.

Defaults to:

'itemtap'

twoWayBindable : String / String[] / Object

bindable bind

This object holds a map of config properties that will update their binding as they are modified. For example, value is a key added by form fields. The form of this config is the same as publishes.

This config is defined so that updaters are not created and added for all bound properties since most cannot be modified by the end-user and hence are not appropriate for two-way binding.

Defaults to:

null

ui : String / String[]

bindable bind

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

userCls : String / String[]

bindable bind

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

useSimpleItems : Boolean

bindable bind

Set this to true if you just want to have the list create simple items that use the itemTpl. These simple items still support headers, grouping and disclosure functionality but avoid container layouts and deeply nested markup. For many Lists using this configuration will drastically increase the scrolling and render performance.

Defaults to:

true

viewModel : String / Object / Ext.app.ViewModel

bindable bind

The ViewModel is a data provider for this component and its children. The data contained in the ViewModel is typically used by adding bind configs to the components that want present or edit this data.

When set, the ViewModel is created and links to any inherited viewModel instance from an ancestor container as the "parent". The ViewModel hierarchy, once established, only supports creation or destruction of children. The parent of a ViewModel cannot be changed on the fly.

If this is a root-level ViewModel, the data model connection is made to this component's associated Ext.data.Session. This is determined by calling getInheritedSession.

Defaults to:

null

width : Number / String

bindable bind

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

x : Number

bindable bind

Only valid when a component is cfg-floated

The x position at which to position this component. This is usually viewport-relative. But if there is a relative: true ancestor, it will be relative to that.

Defaults to:

0

xtype : String

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.

y : Number

bindable bind

Only valid when a component is cfg-floated

The x position at which to position this component. This is usually viewport-relative. But if there is a relative: true ancestor, it will be relative to that.

Defaults to:

0

zIndex : Number

bindable bind

The z-index to give this Component when it is rendered.

Not valid for cfg-floated Components. The Z ordering of cfg-floated Components is managed by ordering of the DOM elements.

Defaults to:

null

defaultBindProperty : String

This property is used to determine the property of a bind config that is just the value. For example, if defaultBindProperty="value", then this shorthand bind config:

 bind: '{name}'

Is equivalent to this object form:

 bind: {
     value: '{name}'
 }

The defaultBindProperty is set to "value" for form fields and to "store" for grids and trees.

Defaults to:

'html'

hasListeners : Object

readonly ro

This object holds a key for any event that has a listener. The listener may be set directly on the instance, or on its class or a super class (via observe) or on the Ext.app.EventBus. The values of this object are truthy (a non-zero number) and falsy (0 or undefined). They do not represent an exact count of listeners. The value for an event is truthy if the event must be fired and is falsy if there is no need to fire the event.

The intended use of this property is to avoid the expense of fireEvent calls when there are no listeners. This can be particularly helpful when one would otherwise have to call fireEvent hundreds or thousands of times. It is used like this:

 if (this.hasListeners.foo) {
     this.fireEvent('foo', this, arg1);
 }

isContainer : Boolean

true in this class to identify an object as an instantiated Container, or subclass thereof.

Defaults to:

true

isObservable : Boolean

true in this class to identify an object as an instantiated Observable, or subclass thereof.

Defaults to:

true

add ( newItems ) : Ext.Component/Ext.Component[]

Adds one or more Components to this Container. Example:

var myPanel = Ext.create('Ext.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

Parameters

Returns

addAfterListener

Alias for onAfter.

addBeforeListener

Alias for onBefore.

addCls ( cls, [prefix], [suffix] )

Adds a CSS class (or classes) to this Component's rendered element.

Parameters

addListener ( eventName, [fn], [scope], [options], [order] ) : Object

chainable ch

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}
});
