-sub-menus, icons, etc.
-
-Example Usage:
Ext.create('Ext.menu.Menu', {
- width: 100,
- height: 100,
- floating: false, // usually you want this set to True (default)
- renderTo: Ext.getBody(), // usually rendered by it's containing component

- text: 'text item',
- },{
- text: 'plain item',
- plain: true
- }]
-});
-Config Options
CSS Class configs
The CSS class added to the menu item when the item is activated (focused/mouseover).
-Defaults to Ext.baseCSSPrefix + 'menu-item-active'.
The base CSS class to apply to this components's element. This will also be prepended to -elements within this component like Panel's body will get a class x-panel-body. This means -that if you create a subclass of Panel, and you want it to get all the Panels styling for the -element and the body, you leave the baseCls x-panel and use componentCls to add specific styling for this -component.
-An optional extra CSS class that will be added to this component's Element (defaults to ''). This can be -useful for adding customized styles to the component or any of its children using standard CSS rules.
-CSS Class to be added to a components root level element to give distinction to it -via styling.

-The CSS class added to the menu item when the item is disabled.
-Defaults to Ext.baseCSSPrefix + 'menu-item-disabled'.

-Defaults to Ext.baseCSSPrefix + 'menu-item-disabled'.
A CSS class that specifies a background-image to use as the icon for this item. Defaults to undefined.
A CSS class that specifies a background-image to use as the icon for this item. Defaults to undefined.
An optional extra CSS class that will be added to this component's Element when the mouse moves -over the Element, and removed when the mouse moves out. (defaults to ''). This can be -useful for adding customized 'active' or 'hover' styles to the component or any of its children using standard CSS rules.
-The class that is added to the content target when you set styleHtmlContent to true. -Defaults to 'x-html'

-Other Configs
The CSS class added to the menu item when the item is activated (focused/mouseover).
-Defaults to Ext.baseCSSPrefix + 'menu-item-active'.
A tag name or DomHelper spec used to create the Element which will -encapsulate this Component.
- - -You do not normally need to specify this. For the base classes Ext.Component and Ext.container.Container, -this defaults to 'div'. The more complex Sencha classes use a more complex -DOM structure specified by their own renderTpls.
- - -This is intended to allow the developer to create application-specific utility Components encapsulated by -different DOM elements. Example usage:
- - -{
- xtype: 'component',
- autoEl: {
- tag: 'img',
- src: 'http://www.example.com/example.jpg'
- }
-}, {
- xtype: 'component',
- autoEl: {
- tag: 'blockquote',
- html: 'autoEl is cool!'
- }
-}, {
- xtype: 'container',
- autoEl: 'ul',
- cls: 'ux-unordered-list',
- items: {
- xtype: 'component',
- autoEl: 'li',
- html: 'First list item'
- }
-}
-This config is intended mainly for floating Components which may or may not be shown. Instead -of using renderTo in the configuration, and rendering upon construction, this allows a Component -to render itself upon first show.
- - -Specify as true to have this Component render to the document body upon first show.
Specify as an element, or the ID of an element to have this Component render to a specific element upon first show.
- - -This defaults to true for the Window class.
true to use overflow:'auto' on the components layout element and show scroll bars automatically when
-necessary, false to clip any overflowing content (defaults to false).
True to automatically show the component upon creation. -This config option may only be used for floating components or components -that use autoRender. Defaults to false.
-The base CSS class to apply to this components's element. This will also be prepended to -elements within this component like Panel's body will get a class x-panel-body. This means -that if you create a subclass of Panel, and you want it to get all the Panels styling for the -element and the body, you leave the baseCls x-panel and use componentCls to add specific styling for this -component.
-Specifies the border for this component. The border can be a single numeric value to apply to all sides or -it can be a CSS style specification for each style, for example: '10 5 3 10'.
-Whether or not this menu item can be activated when focused/mouseovered. Defaults to true.
Whether or not this menu item can be activated when focused/mouseovered. Defaults to true.
The delay in milliseconds to wait before hiding the menu after clicking the menu item.
-This only has an effect when hideOnClick: true. Defaults to 1.
An optional extra CSS class that will be added to this component's Element (defaults to ''). This can be -useful for adding customized styles to the component or any of its children using standard CSS rules.
-CSS Class to be added to a components root level element to give distinction to it -via styling.
-CSS Class to be added to a components root level element to give distinction to it -via styling.
-The sizing and positioning of a Component's internal Elements is the responsibility of -the Component's layout manager which sizes a Component's internal structure in response to the Component being sized.
- - -Generally, developers will not use this configuration as all provided Components which need their internal -elements sizing (Such as input fields) come with their own componentLayout managers.
- - -The default layout manager will be used on instances of the base Ext.Component class -which simply sizes the Component's encapsulating element to the height and width specified in the setSize method.
- -Optional. Specify an existing HTML element, or the id of an existing HTML element to use as the content
-for this component.
-
-
- Description :
-This config option is used to take an existing HTML element and place it in the layout element -of a new component (it simply moves the specified DOM element after the Component is rendered to use as the content.
-
- Notes :
-The specified HTML element is appended to the layout element of the component after any configured -HTML has been inserted, and so the document will not contain this element at the time the render event is fired.-The specified HTML element used will not participate in any-
layout-scheme that the Component may use. It is just HTML. Layouts operate on childitems.Add either thex-hiddenor thex-hide-displayCSS class to -prevent a brief flicker of the content before it is rendered to the panel.
-
Whether or not to destroy any associated sub-menu when this item is destroyed. Defaults to true.
Whether or not to destroy any associated sub-menu when this item is destroyed. Defaults to true.
The CSS class added to the menu item when the item is disabled.
-Defaults to Ext.baseCSSPrefix + 'menu-item-disabled'.
The CSS class added to the menu item when the item is disabled.
-Defaults to Ext.baseCSSPrefix + 'menu-item-disabled'.
Specify as true to make a floating Component draggable using the Component's encapsulating element as the drag handle.
- - -This may also be specified as a config object for the ComponentDragger which is instantiated to perform dragging.
- - -For example to create a Component which may only be dragged around using a certain internal element as the drag handle, -use the delegate option:
- - -new Ext.Component({
- constrain: true,
- floating:true,
- style: {
- backgroundColor: '#fff',
- border: '1px solid black'
- },
- html: '<h1 style="cursor:move">The title</h1><p>The content</p>',
- draggable: {
- delegate: 'h1'
- }
-}).show();
-
-
-
-
-Specify as true to float the Component outside of the document flow using CSS absolute positioning.
- - -Components such as Windows and Menus are floating -by default.
- - -Floating Components that are programatically rendered will register themselves with the global -ZIndexManager
- - -Floating Components as child items of a Container
- - -A floating Component may be used as a child item of a Container. This just allows the floating Component to seek a ZIndexManager by -examining the ownerCt chain.
- - -When configured as floating, Components acquire, at render time, a ZIndexManager which manages a stack -of related floating Components. The ZIndexManager brings a single floating Component to the top of its stack when -the Component's toFront method is called.
- - -The ZIndexManager is found by traversing up the ownerCt chain to find an ancestor which itself is floating. This is so that -descendant floating Components of floating Containers (Such as a ComboBox dropdown within a Window) can have its zIndex managed relative -to any siblings, but always above that floating ancestor Container.
- - -If no floating ancestor is found, a floating Component registers itself with the default ZIndexManager.
- - -Floating components do not participate in the Container's layout. Because of this, they are not rendered until you explicitly -show them.
- - -After rendering, the ownerCt reference is deleted, and the floatParent property is set to the found floating ancestor Container. -If no floating ancestor Container was found the floatParent property will not be set.
- -Specifies whether the floated component should be automatically focused when it is -brought to the front. Defaults to true.
-Specify as true to have the Component inject framing elements within the Component at render time to
-provide a graphical rounded frame around the Component content.
This is only necessary when running on outdated, or non standard-compliant browsers such as Microsoft's Internet Explorer -prior to version 9 which do not support rounded corners natively.
- - -The extra space taken up by this framing is available from the read only property frameSize.
- -A String which specifies how this Component's encapsulating DOM element will be hidden. -Values may be
-
-
'display': The Component will be hidden using thedisplay: nonestyle.
-'visibility': The Component will be hidden using thevisibility: hiddenstyle.
-'offsets': The Component will be hidden by absolutely positioning it out of the visible area of the document. This -is useful when a hidden Component must maintain measurable dimensions. Hiding usingdisplayresults -in a Component having zero dimensions.
'display'.
-Whether to not to hide the owning menu when this item is clicked. Defaults to true.
Whether to not to hide the owning menu when this item is clicked. Defaults to true.
The href attribute to use for the underlying anchor link. Defaults to #.
The href attribute to use for the underlying anchor link. Defaults to #.
The target attribute to use for the underlying anchor link. Defaults to undefined.
The target attribute to use for the underlying anchor link. Defaults to undefined.
An HTML fragment, or a DomHelper specification to use as the layout element -content (defaults to ''). The HTML content is added after the component is rendered, -so the document will not contain this HTML at the time the render event is fired. -This content is inserted into the body before any configured contentEl is appended.
-The path to an icon to display in this item. Defaults to Ext.BLANK_IMAGE_URL.
The path to an icon to display in this item. Defaults to Ext.BLANK_IMAGE_URL.
A CSS class that specifies a background-image to use as the icon for this item. Defaults to undefined.
A CSS class that specifies a background-image to use as the icon for this item. Defaults to undefined.
The unique id of this component instance (defaults to an auto-assigned id).
- - -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 ComponentQuery which -provides selector-based searching for Sencha Components analogous to DOM querying. The 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.
Note: to access the container of a Component see ownerCt.
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.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.
var c = new Ext.panel.Panel({ //
- height: 300,
- renderTo: document.body,
- layout: 'auto',
- items: [
- {
- itemId: 'p1',
- title: 'Panel 1',
- height: 150
- },
- {
- itemId: 'p2',
- title: 'Panel 2',
- height: 150
- }
- ]
-})
-p1 = c.getComponent('p1'); // not the same as Ext.getCmp()
-p2 = p1.ownerCt.getComponent('p2'); // reference via a sibling
-Also see id, query, down and child.
Note: to access the container of an item see ownerCt.
- -(optional)
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 ExtJs Components
- - -While some ExtJs 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
-click 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'); }
- }
- }
-});
-A configuration object or an instance of a Ext.ComponentLoader to load remote -content for this Component.
-A configuration object or an instance of a Ext.ComponentLoader to load remote -content for this Component.
-Specifies the margin for this component. The margin can be a single numeric value to apply to all sides or -it can be a CSS style specification for each style, for example: '10 5 3 10'.
-The maximum value in pixels which this Component will set its height to.
- - -Warning: This will override any size management applied by layout managers.
- -The maximum value in pixels which this Component will set its width to.
- - -Warning: This will override any size management applied by layout managers.
- -The minimum value in pixels which this Component will set its height to.
- - -Warning: This will override any size management applied by layout managers.
- -The minimum value in pixels which this Component will set its width to.
- - -Warning: This will override any size management applied by layout managers.
- -An optional extra CSS class that will be added to this component's Element when the mouse moves -over the Element, and removed when the mouse moves out. (defaults to ''). This can be -useful for adding customized 'active' or 'hover' styles to the component or any of its children using standard CSS rules.
-Specifies the padding for this component. The padding can be a single numeric value to apply to all sides or -it can be a CSS style specification for each style, for example: '10 5 3 10'.
-Whether or not this item is plain text/html with no icon or visual activation. Defaults to false.
Whether or not this item is plain text/html with no icon or visual activation. Defaults to false.
An object or array of objects that will provide custom functionality for this component. The only -requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.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.
-An object containing properties specifying DomQuery selectors which identify child elements -created by the render process.
- -After the Component's internal structure is rendered according to the renderTpl, this object is iterated through,
-and the found Elements are added as properties to the Component using the renderSelector property name.
For example, a Component which rendered an image, and description into its element might use the following properties -coded into its prototype:
- -renderTpl: '<img src="{imageUrl}" class="x-image-component-img"><div class="x-image-component-desc">{description}>/div<',
-
-renderSelectors: {
- image: 'img.x-image-component-img',
- descEl: 'div.x-image-component-desc'
-}
-After rendering, the Component would have a property image referencing its child img Element,
-and a property descEl referencing the div Element which contains the description.
Specify the id of the element, a DOM element or an existing Element that this component -will be rendered into.
- - --
-
- Notes :
-
-
Do not use this option if the Component is to be a child item of -a Container. It is the responsibility of the -Container's layout manager -to render and manage its child items.-When using this config, a call to render() is not required.-
-
See render also.
An XTemplate used to create the internal structure inside this Component's -encapsulating Element.
- - -You do not normally need to specify this. For the base classes Ext.Component
-and Ext.container.Container, this defaults to null which means that they will be initially rendered
-with no internal structure; they render their Element empty. The more specialized ExtJS and Touch classes
-which use a more complex DOM structure, provide their own template definitions.
This is intended to allow the developer to create application-specific utility Components with customized -internal structure.
- - -Upon rendering, any created child elements may be automatically imported into object properties using the -renderSelectors option.
- -Specify as true to apply a Resizer to this Component
-after rendering.
May also be specified as a config object to be passed to the constructor of Resizer
-to override any defaults. By default the Component passes its minimum and maximum size, and uses
-Ext.resizer.Resizer.dynamic: false
A valid Ext.resizer.Resizer handles config string (defaults to 'all'). Only applies when resizable = true.
-A valid Ext.resizer.Resizer handles config string (defaults to 'all'). Only applies when resizable = true.
-A buffer to be applied if many state events are fired within -a short period. Defaults to 100.
-A buffer to be applied if many state events are fired within -a short period. Defaults to 100.
-Specifies whether the floating component should be given a shadow. Set to -true to automatically create an Ext.Shadow, or a string indicating the -shadow's display Ext.Shadow.mode. Set to false to disable the shadow. -(Defaults to 'sides'.)
-An array of events that, when fired, should trigger this object to
-save its state (defaults to none). stateEvents may be any type
-of event supported by this object, including browser or custom events
-(e.g., ['click', 'customerchange']).
See stateful for an explanation of saving and
-restoring object state.
The unique id for this object to use for state management purposes.
- -See stateful for an explanation of saving and restoring state.
- -A flag which causes the object to attempt to restore the state of
-internal properties from a saved state on startup. The object must have
-a stateId for state to be managed.
-Auto-generated ids are not guaranteed to be stable across page loads and
-cannot be relied upon to save and restore the same state for a object.
-
For state saving to work, the state manager's provider must have been -set to an implementation of Ext.state.Provider which overrides the -set and get -methods to save and recall name/value pairs. A built-in implementation, -Ext.state.CookieProvider is available.
-To set the state provider for the current page:
-Ext.state.Manager.setProvider(new Ext.state.CookieProvider({
- expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now
-}));
-A stateful object attempts to save state when one of the events
-listed in the stateEvents configuration fires.
To save state, a stateful object first serializes its state by
-calling getState. By default, this function does
-nothing. The developer must provide an implementation which returns an
-object hash which represents the restorable state of the object.
The value yielded by getState is passed to Ext.state.Manager.set
-which uses the configured Ext.state.Provider to save the object
-keyed by the stateId
During construction, a stateful object attempts to restore
-its state by calling Ext.state.Manager.get passing the
-stateId
The resulting object is passed to applyState.
-The default implementation of applyState simply copies
-properties into the object, but a developer may override this to support
-more behaviour.
You can perform extra processing on state save and restore by attaching -handlers to the beforestaterestore, staterestore, -beforestatesave and statesave events.
- -A custom style specification to be applied to this component's Element. Should be a valid argument to -Ext.core.Element.applyStyles.
- - new Ext.panel.Panel({
- title: 'Some Title',
- renderTo: Ext.getBody(),
- width: 400, height: 300,
- layout: 'form',
- items: [{
- xtype: 'textarea',
- style: {
- width: '95%',
- marginBottom: '10px'
- }
- },
- new Ext.button.Button({
- text: 'Send',
- minWidth: '100',
- style: {
- marginBottom: '10px'
- }
- })
- ]
- });
- The class that is added to the content target when you set styleHtmlContent to true. -Defaults to 'x-html'
-The class that is added to the content target when you set styleHtmlContent to true. -Defaults to 'x-html'
-True to automatically style the html inside the content target of this component (body for panels). -Defaults to false.
-True to automatically style the html inside the content target of this component (body for panels). -Defaults to false.
-The text/html to display in this item. Defaults to undefined.
The text/html to display in this item. Defaults to undefined.
An data and
-tplWriteMode configurations.
The Ext.(X)Template method to use when
-updating the content area of the Component. Defaults to 'overwrite'
-(see Ext.XTemplate.overwrite).
Properties
Read-only property indicating whether or not the component can be dragged
-Read-only property indicating whether or not the component can be dragged
-Optional. Only present for floating Components which were inserted as descendant items of floating Containers.
- - -Floating Components that are programatically rendered will not have a floatParent property.
For floating Components which are child items of a Container, the floatParent will be the floating ancestor Container which is -responsible for the base z-index value of all its floating descendants. It provides a ZIndexManager which provides -z-indexing services for all its descendant floating Components.
- - -For example, the dropdown BoundList of a ComboBox which is in a Window will have the Window as its
-floatParent
See floating and zIndexManager
- -Read-only property indicating the width of any framing elements which were added within the encapsulating element -to provide graphical, rounded borders. See the frame config.
- - -This is an object containing the frame width in pixels for all four sides of the Component containing -the following properties:
- - --
-
topThe width of the top framing element in pixels.
-rightThe width of the right framing element in pixels.
-bottomThe width of the bottom framing element in pixels.
-leftThe width of the left framing element in pixels.
-
@deprecated 4.0 Replaced by getActiveAnimation -Returns thq current animation if this object has any effects actively running or queued, else returns false.
-This is an internal flag that you use when creating custom components. -By default this is set to true which means that every component gets a mask when its disabled. -Components like FieldContainer, FieldSet, Field, Button, Tab override this property to false -since they want to implement custom disable logic.
-Read-only property indicating whether or not the component has been rendered.
-Read-only property indicating whether or not the component has been rendered.
-Stops any running effects and clears this object's internal effects queue if it contains -any additional effects that haven't started yet.
-Optional. Only present for floating Components after they have been rendered.
- - -A reference to the ZIndexManager which is managing this Component's z-index.
- - -The ZIndexManager maintains a stack of floating Component z-indices, and also provides a single modal -mask which is insert just beneath the topmost visible modal floating Component.
- - -Floating Components may be brought to the front or sent to the back of the z-index stack.
- - -This defaults to the global ZIndexManager for floating Components that are programatically -rendered.
- - -For floating Components which are added to a Container, the ZIndexManager is acquired from the first ancestor Container found -which is floating, or if not found the global ZIndexManager is used.
- - -See floating and floatParent

- - handler : Function
The method the event invokes.
- - scope : Object
(optional) The scope (
-thisreference) 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. -properties. This may contain any of the following properties:
-
-
- scope : ObjectThe scope (
thisreference) in which the handler function is executed. -If omitted, defaults to the object which fired the event.

-
Returns
- Component
this
-
Perform custom animation on this object.
-
This method is applicable to both the the Component class and the Element class. -It performs animated transitions of certain properties of this object over a specified timeline.
-The sole parameter is an object which specifies start property values, end property values, and properties which
-describe the timeline. Of the properties listed below, only to is mandatory.
Properties include
-
-
fromAn object which specifies start values for the properties being animated. -If not supplied, properties are animated from current settings. The actual properties which may be animated depend upon -ths object being animated. See the sections below on Element and Component animation.-toAn object which specifies end values for the properties being animated.durationThe duration in milliseconds for which the animation will run.easingA string value describing an easing type to modify the rate of change from the default linear to non-linear. Values may be one of:-
-
- ease -
- easeIn -
- easeOut -
- easeInOut -
- backIn -
- backOut -
- elasticIn -
- elasticOut -
- bounceIn -
- bounceOut -
keyframesThis is an object which describes the state of animated properties at certain points along the timeline. -it is an object containing properties who's names are the percentage along the timeline being described and who's values specify the animation state at that point.listenersThis is a standard listeners configuration object which may be used -to inject behaviour at either thebeforeanimateevent or theafteranimateevent.Animating an Element
-When animating an Element, the following properties may be specified infrom,to, andkeyframeobjects:-
-
xThe page X position in pixels.
-yThe page Y position in pixels
-leftThe element's CSSleftvalue. Units must be supplied.
-topThe element's CSStopvalue. Units must be supplied.
-widthThe element's CSSwidthvalue. Units must be supplied.
-heightThe element's CSSheightvalue. Units must be supplied.
-scrollLeftThe element'sscrollLeftvalue.
-scrollTopThe element'sscrollLeftvalue.
-opacityThe element'sopacityvalue. This must be a value between0and1.
-
Be aware than animating an Element which is being used by an Ext Component without in some way informing the Component about the changed element state -will result in incorrect Component behaviour. This is because the Component will be using the old state of the element. To avoid this problem, it is now possible to -directly animate certain properties of Components.
-Animating a Component
-When animating an Element, the following properties may be specified infrom,to, andkeyframeobjects:-
-
xThe Component's page X position in pixels.
-yThe Component's page Y position in pixels
-leftThe Component'sleftvalue in pixels.
-topThe Component'stopvalue in pixels.
-widthThe Component'swidthvalue in pixels.
-widthThe Component'swidthvalue in pixels.
-dynamicSpecify as true to update the Component's layout (if it is a Container) at every frame -of the animation. Use sparingly as laying out on every intermediate size change is an expensive operation.
-
For example, to animate a Window to a new size, ensuring that its internal layout, and any shadow is correct:
-
-myWindow = Ext.create('Ext.window.Window', { - title: 'Test Component animation', - width: 500, - height: 300, - layout: { - type: 'hbox', - align: 'stretch' - }, - items: [{ - title: 'Left: 33%', - margins: '5 0 5 5', - flex: 1 - }, { - title: 'Left: 66%', - margins: '5 5 5 5', - flex: 2 - }] -}); -myWindow.show(); -myWindow.header.el.on('click', function() { - myWindow.animate({ - to: { - width: (myWindow.getWidth() == 500) ? 700 : 500, - height: (myWindow.getHeight() == 300) ? 400 : 300, - } - }); -}); -For performance reasons, by default, the internal layout is only updated when the Window reaches its final
- -"to"size. If dynamic updating of the Window's child -Components is required, then configure the animation withdynamic: trueand the two child items will maintain their proportions during the animation.Parameters
