Ext.menu.DatePickerxtype: datemenu

Adds Component(s) to this Container.

Description:

• Fires the beforeadd event before adding.
• The Container's default config values will be applied accordingly (see defaults for details).
• Fires the add event after the component has been added.

Notes:

If the Container is already rendered when add is called, it will render the newly added Component into its content area.

If the Container was configured with a size-managing layout manager, the Container will recalculate its internal layout at this time too.

Note that the default layout manager simply renders child Components sequentially into the content area and thereafter performs no sizing.

If adding multiple new child Components, pass them as an array to the add method, so that only one layout recalculation is performed.

tb = new Ext.toolbar.Toolbar({
    renderTo: document.body
});  // toolbar is rendered
tb.add([{text:'Button 1'}, {text:'Button 2'}]); // add multiple items. (defaultType for Toolbar is 'button')

Warning:##

Components directly managed by the BorderLayout layout manager may not be removed or added. See the Notes for BorderLayout for more details.

Parameters

• Component : ...Object/Array

  Either one or more Components to add or an Array of Components to add. See items for additional information.

Returns

• Ext.Component/Array   

  The Components that were added.

@deprecated 4.0 Replaced by {link:#addCls} Adds a CSS class to the top level element representing this component.

Parameters

• cls : String

  The CSS class name to add

Returns

• Ext.Component   

  Returns the Component to allow method chaining.

Adds a CSS class to the top level element representing this component.

Parameters

• cls : String

  The CSS class name to add

Returns

• Ext.Component   

  Returns the Component to allow method chaining.

Adds a cls to the uiCls array, which will also call addUIClsToElement and adds to all elements of this component.

Parameters

• cls : String/Array

  A string or an array of strings to add to the uiCls

Returns

• void   

Adds docked item(s) to the panel.

Parameters

• component : Object/Array

  The Component or array of components to add. The components must include a 'dock' parameter on each component to indicate where it should be docked ('top', 'right', 'bottom', 'left').

• pos : Number

  (optional) The index at which the Component will be added

Returns

• void   

Adds the specified events to the list of events which this Observable may fire.

Parameters

• o : Object/String

  Either an object with event names as properties with a value of true or the first event name string if multiple event names are being passed as separate parameters.

• : String

  [additional] Optional additional event names if multiple event names are being passed as separate parameters. Usage:

  this.addEvents('storeloaded', 'storecleared');
  

Returns

• void   

Appends an event handler to this object.

Parameters

• eventName : String

  The name of the event to listen for. May also be an object who's property names are event names. See

• handler : Function

  The method the event invokes.

• 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. properties. This 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.
  • target : 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 Components. The name of a Component property which references an element to add a listener to.

    This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

    new Ext.panel.Panel({
        title: 'The title',
        listeners: {
            click: this.handlePanelClick,
            element: 'body'
        }
    });
    

    When added in this way, the options available are the options applicable to Ext.core.Element.addListener

  
  

  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 events. For example:

  myGridPanel.on({
      cellClick: this.onCellClick,
      mouseover: this.onMouseOver,
      mouseout: this.onMouseOut,
      scope: this // Important. Ensure "this" is correct during handler execution
  });
  

  .

• position : String

  (optional, defaults to "tl-bl?") The position to align to (see Ext.core.Element.alignTo for more details).

• offsets : Array

  (optional) Offset the positioning by [x, y]

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

• from
  An 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.
• to
  An object which specifies end values for the properties being animated.
• duration
  The duration in milliseconds for which the animation will run.
• easing
  A 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
• keyframes
  This 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.
• listeners
  This is a standard listeners configuration object which may be used to inject behaviour at either the beforeanimate event or the afteranimate event.

Animating an Element

• x
  The page X position in pixels.
• y
  The page Y position in pixels
• left
  The element's CSS left value. Units must be supplied.
• top
  The element's CSS top value. Units must be supplied.
• width
  The element's CSS width value. Units must be supplied.
• height
  The element's CSS height value. Units must be supplied.
• scrollLeft
  The element's scrollLeft value.
• scrollTop
  The element's scrollLeft value.
• opacity
  The element's opacity value. This must be a value between 0 and 1.

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

• x
  The Component's page X position in pixels.
• y
  The Component's page Y position in pixels
• left
  The Component's left value in pixels.
• top
  The Component's top value in pixels.
• width
  The Component's width value in pixels.
• width
  The Component's width value in pixels.
• dynamic
  Specify 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 with dynamic: true and the two child items will maintain their proportions during the animation.

Parameters

• config : Object

  An object containing properties which describe the animation's start and end states, and the timeline of the animation.

Returns

• Object   

  this

Applies the state to the object. This should be overridden in subclasses to do more complex state operations. By default it applies the state properties onto the current object.

Parameters

• state : Object

Enable the component

Parameters

• silent : Boolean

  Passing false will supress the 'enable' event from being fired.

Returns

• void   

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.override(Ext.form.field.Base, {
//  Add functionality to Field's initComponent to enable the change event to bubble
initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
    this.enableBubble('change');
}),

//  We know that we want Field's events to bubble directly to the FormPanel.
getBubbleTarget : function() {
    if (!this.formPanel) {
        this.formPanel = this.findParentByType('form');
    }
    return this.formPanel;
}
});

var myForm = new Ext.formPanel({
title: 'User Details',
items: [{
    ...
}],
listeners: {
    change: function() {
        // Title goes red if form has been modified.
        myForm.header.setStyle('color', 'red');
    }
}
});

Parameters

• events : String/Array

  The event name to bubble, or an Array of event names.

Returns

• void

  True to animate the transition, else false (defaults to the value of the animCollapse panel config)

Returns

• Ext.panel.Panel

Returns this Component's xtype hierarchy as a slash-delimited string. For a list of all available xtypes, see the Ext.Component header.

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.form.field.Text();
alert(t.getXTypes());  // alerts 'component/field/textfield'

Returns

• index : Number

  The index at which the Component will be inserted into the Container's items collection

• component : Ext.Component

  The child Component to insert.
  
  Ext uses lazy rendering, and will only render the inserted Component should it become necessary.
  
  A Component config object may be passed in order to avoid the overhead of constructing a real Component object if lazy rendering might mean that the inserted Component will not be rendered immediately. To take advantage of this 'lazy instantiation', set the Ext.Component.xtype config property to the registered type of the Component wanted.
  
  For a list of all available xtypes, see Ext.Component.

Returns

• Ext.Component   

  component The Component (or config object) that was inserted with the Container's default config values applied.

  the hidden state of this Component.

Returns true if this component is visible.

Parameters

• deep : Boolean

  .

  Optional. Pass true to interrogate the visibility status of all parent Containers to determine whether this Component is truly visible to the user.

  Generally, to determine whether a Component is hidden, the no argument form is needed. For example when creating dynamically laid out UIs in a hidden Container before showing them.

Returns

• Boolean   

  True if this component is visible, false otherwise.

Tests whether or not this Component is of a specific xtype. This can test whether this Component is descended from the xtype (default) or whether it is directly of the xtype specified (shallow = true).

If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.

For a list of all available xtypes, see the Ext.Component header.

Example usage:

var t = new Ext.form.field.Text();
var isText = t.isXType('textfield');        // true
var isBoxSubclass = t.isXType('field');       // true, descended from Ext.form.field.Base

Note that this is not limited to siblings, and if invoked upon a node with no matching siblings, will walk the tree to attempt to find a match. Contrast with pnextSibling.

Parameters

• selector : String

  Optional A ComponentQuery selector to filter the following nodes.

• includeSelf : Object

Returns

• void   

  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.

Optionally selects the next sibling which matches the passed ComponentQuery selector.

May also be refered to as next()

Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with nextNode

Parameters

• selector : String

  Optional A ComponentQuery selector to filter the following items.

Returns

• void   

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

Sets observability on the passed class constructor.

This makes any event fired on any instance of the passed class also fire a single event through the class allowing for central handling of events on many instances at once.

Usage:

Ext.util.Observable.observe(Ext.data.Connection);
Ext.data.Connection.on('beforerequest', function(con, options) {
    console.log('Ajax request made to ' + options.url);
});

Parameters

• c : Function

  The class constructor to make observable.

• listeners : Object

  An object containing a series of listeners to add. See addListener.

Returns

• void   

Appends an event handler to this object (shorthand for addListener.)

Parameters

• eventName : String

  The type of event to listen for

• handler : Function

  The method the event invokes

• 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.

Returns

• void   

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.

Parameters

• selector : String

  Optional. A ComponentQuery selector to filter the preceding nodes.

• includeSelf : Object

Returns

• void   

  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 ComponentQuery selector.

May also be refered to as prev()

Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with previousNode

Parameters

• selector : String

  Optional. A ComponentQuery selector to filter the preceding items.

Returns

• void   

  The previous sibling (or the previous sibling which matches the selector). Returns null if there is no matching sibling.
