Creates a Pie Chart. A Pie Chart is a useful visualization technique to display quantitative information for different categories that also have a meaning as a whole. As with all other series, the Pie Series must be appended in the series Chart array configuration. See the Chart documentation for more information. A typical configuration object for the pie series could be:

var store = Ext.create('Ext.data.JsonStore', {
    fields: ['name', 'data'],
    data: [
        { 'name': 'metric one',   'data': 10 },
        { 'name': 'metric two',   'data':  7 },
        { 'name': 'metric three', 'data':  5 },
        { 'name': 'metric four',  'data':  2 },
        { 'name': 'metric five',  'data': 27 }
    ]
});

Ext.create('Ext.chart.Chart', {
    renderTo: Ext.getBody(),
    width: 500,
    height: 350,
    animate: true,
    store: store,
    theme: 'Base:gradients',
    series: [{
        type: 'pie',
        angleField: 'data',
        showInLegend: true,
        tips: {
            trackMouse: true,
            width: 140,
            height: 28,
            renderer: function(storeItem, item) {
                // calculate and display percentage on hover
                var total = 0;
                store.each(function(rec) {
                    total += rec.get('data');
                });
                this.setTitle(storeItem.get('name') + ': ' + Math.round(storeItem.get('data') / total * 100) + '%');
            }
        },
        highlight: {
            segment: {
                margin: 20
            }
        },
        label: {
            field: 'name',
            display: 'rotate',
            contrast: true,
            font: '18px Arial'
        }
    }]
});

In this configuration we set pie as the type for the series, set an object with specific style properties for highlighting options (triggered when hovering elements). We also set true to showInLegend so all the pie slices can be represented by a legend item.

We set data as the value of the field to determine the angle span for each pie slice. We also set a label configuration object where we set the field name of the store field to be renderer as text for the label. The labels will also be displayed rotated.

We set contrast to true to flip the color of the label if it is to similar to the background color. Finally, we set the font family and size through the font parameter.

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 MVC 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);

Parameters

Returns

Overrides: Ext.chart.Highlight.constructor

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

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

Available since: 1.1.0

Parameters

  • eventNames : Object/String...

    Either an object with event names as properties with a value of true. For example:

    this.addEvents({
        storeloaded: true,
        storecleared: true
    });
    

    Or any number of event names as separate parameters. For example:

    this.addEvents('storeloaded', 'storecleared');
    
( eventName, [fn], [scope], [options] ) : Object
Appends an event handler to this object. ...

Appends an event handler to this object. For example:

myGridPanel.on("mouseover", this.onMouseOver, 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,
    mouseover: this.onMouseOver,
    mouseout: this.onMouseOut,
    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},
    mouseover: {fn: panel.onMouseOver, scope: panel}
});

Names of methods in a specified scope may also be used. Note that scope MUST be specified to use this option:

myGridPanel.on({
    cellClick: {fn: 'onCellClick', scope: this, single: true},
    mouseover: {fn: 'onMouseOver', scope: panel}
});

Available since: 1.1.0

Parameters

  • eventName : String/Object

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

  • fn : Function (optional)

    The method the event invokes, or if scope is specified, the name* of the method within the specified scope. Will be called with arguments given to fireEvent plus the options parameter described below.

  • scope : Object (optional)

    The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

  • options : Object (optional)

    An object containing handler configuration.

    Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

    This object may contain any of the following properties:

    • scope : Object

      The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

    • delay : Number

      The number of milliseconds to delay the invocation of the handler after the event fires.

    • single : Boolean

      True to add a handler to handle just the next firing of the event, and then remove itself.

    • buffer : Number

      Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

    • target : Ext.util.Observable

      Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

    • element : String

      This option is only valid for listeners bound to 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'
            }
        });
      
    • destroyable : Boolean (optional)

      When specified as true, the function returns A Destroyable object. An object which implements the destroy method which removes all listeners added in this call.

      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
      });
      

      Defaults to: false

Returns

  • Object

    Only when the destroyable option is specified.

    A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

    this.btnListeners =  = myButton.on({
        destroyable: true
        mouseover:   function() { console.log('mouseover'); },
        mouseout:    function() { console.log('mouseout'); },
        click:       function() { console.log('click'); }
    });
    

    And when those listeners need to be removed:

    Ext.destroy(this.btnListeners);
    

    or

    this.btnListeners.destroy();
    

Overrides: Ext.AbstractComponent.addListener

Available since: 4.0.0

Parameters

  • item : Ext.util.Observable/Ext.Element

    The item to which to add a listener/listeners.

  • ename : Object/String

    The event name, or an object containing event name properties.

  • fn : Function (optional)

    If the ename parameter was an event name, this is the handler function.

  • scope : Object (optional)

    If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

  • options : Object (optional)

    If the ename parameter was an event name, this is the addListener options.

Returns

  • Object

    Only when the destroyable option is specified.

    A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

    this.btnListeners =  = myButton.mon({
        destroyable: true
        mouseover:   function() { console.log('mouseover'); },
        mouseout:    function() { console.log('mouseout'); },
        click:       function() { console.log('click'); }
    });

This method has been deprecated

as of 4.1. Use callParent instead.

Available since: 4.0.0

Parameters

  • args : Array/Arguments

    The arguments, either an array or the arguments object from the current method, for example: this.callOverridden(arguments)

Returns

  • Object

    Returns the result of calling the overridden method

Call the "parent" method of the current method. ...

Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext.define).

 Ext.define('My.Base', {
     constructor: function (x) {
         this.x = x;
     },

     statics: {
         method: function (x) {
             return x;
         }
     }
 });

 Ext.define('My.Derived', {
     extend: 'My.Base',

     constructor: function () {
         this.callParent([21]);
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // alerts 21

This can be used with an override as follows:

 Ext.define('My.DerivedOverride', {
     override: 'My.Derived',

     constructor: function (x) {
         this.callParent([x*2]); // calls original My.Derived constructor
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // now alerts 42

This also works with static methods.

 Ext.define('My.Derived2', {
     extend: 'My.Base',

     statics: {
         method: function (x) {
             return this.callParent([x*2]); // calls My.Base.method
         }
     }
 });

 alert(My.Base.method(10);     // alerts 10
 alert(My.Derived2.method(10); // alerts 20

Lastly, it also works with overridden static methods.

 Ext.define('My.Derived2Override', {
     override: 'My.Derived2',

     statics: {
         method: function (x) {
             return this.callParent([x*2]); // calls My.Derived2.method
         }
     }
 });

 alert(My.Derived2.method(10); // now alerts 40

To override a method and replace it and also call the superclass method, use callSuper. This is often done to patch a method to fix a bug.

Available since: 4.0.0

Parameters

  • args : Array/Arguments

    The arguments, either an array or the arguments object from the current method, for example: this.callParent(arguments)

Returns

  • Object

    Returns the result of calling the parent method

( args ) : Objectprotected
This method is used by an override to call the superclass method but bypass any overridden method. ...

This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.

Consider:

 Ext.define('Ext.some.Class', {
     method: function () {
         console.log('Good');
     }
 });

 Ext.define('Ext.some.DerivedClass', {
     method: function () {
         console.log('Bad');

         // ... logic but with a bug ...

         this.callParent();
     }
 });

To patch the bug in DerivedClass.method, the typical solution is to create an override:

 Ext.define('App.paches.DerivedClass', {
     override: 'Ext.some.DerivedClass',

     method: function () {
         console.log('Fixed');

         // ... logic but with bug fixed ...

         this.callSuper();
     }
 });

The patch method cannot use callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good".

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. ...

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. There is no implementation in the Observable base class.

This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.

Example:

Ext.define('Ext.overrides.form.field.Base', {
    override: 'Ext.form.field.Base',

    //  Add functionality to Field's initComponent to enable the change event to bubble
    initComponent: function () {
        this.callParent();
        this.enableBubble('change');
    }
});

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

Available since: 3.4.0

Parameters

Shorthand for addManagedListener. ...

Shorthand for addManagedListener.

Adds listeners to any Observable object (or Ext.Element) which are automatically removed when this Component is destroyed.

Available since: 4.0.2

Parameters

  • item : Ext.util.Observable/Ext.Element

    The item to which to add a listener/listeners.

  • ename : Object/String

    The event name, or an object containing event name properties.

  • fn : Function (optional)

    If the ename parameter was an event name, this is the handler function.

  • scope : Object (optional)

    If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

  • options : Object (optional)

    If the ename parameter was an event name, this is the addListener options.

Returns

  • Object

    Only when the destroyable option is specified.

    A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

    this.btnListeners =  = myButton.mon({
        destroyable: true
        mouseover:   function() { console.log('mouseover'); },
        mouseout:    function() { console.log('mouseout'); },
        click:       function() { console.log('click'); }
    });
    

    And when those listeners need to be removed:

    Ext.destroy(this.btnListeners);
    

    or

    this.btnListeners.destroy();
    
( item, ename, [fn], [scope] )
Shorthand for removeManagedListener. ...

Shorthand for removeManagedListener.

Removes listeners that were added by the mon method.

Available since: 4.0.2

Parameters

  • item : Ext.util.Observable/Ext.Element

    The item from which to remove a listener/listeners.

  • ename : Object/String

    The event name, or an object containing event name properties.

  • fn : Function (optional)

    If the ename parameter was an event name, this is the handler function.

  • scope : Object (optional)

    If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

( eventName, [fn], [scope], [options] ) : Object
Shorthand for addListener. ...

Shorthand for addListener.

Appends an event handler to this object. For example:

myGridPanel.on("mouseover", this.onMouseOver, 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,
    mouseover: this.onMouseOver,
    mouseout: this.onMouseOut,
    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},
    mouseover: {fn: panel.onMouseOver, scope: panel}
});

Names of methods in a specified scope may also be used. Note that scope MUST be specified to use this option:

myGridPanel.on({
    cellClick: {fn: 'onCellClick', scope: this, single: true},
    mouseover: {fn: 'onMouseOver', scope: panel}
});

Available since: 1.1.0

Parameters

  • eventName : String/Object

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

  • fn : Function (optional)

    The method the event invokes, or if scope is specified, the name* of the method within the specified scope. Will be called with arguments given to fireEvent plus the options parameter described below.

  • scope : Object (optional)

    The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

  • options : Object (optional)

    An object containing handler configuration.

    Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

    This object may contain any of the following properties:

    • scope : Object

      The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

    • delay : Number

      The number of milliseconds to delay the invocation of the handler after the event fires.

    • single : Boolean

      True to add a handler to handle just the next firing of the event, and then remove itself.

    • buffer : Number

      Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

    • target : Ext.util.Observable

      Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

    • element : String

      This option is only valid for listeners bound to 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'
            }
        });
      
    • destroyable : Boolean (optional)

      When specified as true, the function returns A Destroyable object. An object which implements the destroy method which removes all listeners added in this call.

      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
      });
      

      Defaults to: false

Returns

  • Object

    Only when the destroyable option is specified.

    A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

    this.btnListeners =  = myButton.on({
        destroyable: true
        mouseover:   function() { console.log('mouseover'); },
        mouseout:    function() { console.log('mouseout'); },
        click:       function() { console.log('click'); }
    });
    

    And when those listeners need to be removed:

    Ext.destroy(this.btnListeners);
    

    or

    this.btnListeners.destroy();

Parameters

Prepares a given class for observable instances. ...

Prepares a given class for observable instances. This method is called when a class derives from this class or uses this class as a mixin.

Available since: 4.1.0

Parameters

  • T : Function

    The class constructor to prepare.

Relays selected events from the specified Observable as if the events were fired by this. ...

Relays selected events from the specified Observable as if the events were fired by this.

For example if you are extending Grid, you might decide to forward some events from store. So you can do this inside your initComponent:

this.relayEvents(this.getStore(), ['load']);

The grid instance will then have an observable 'load' event which will be passed the parameters of the store's load event and any function fired with the grid's load event would have access to the grid using the this keyword.

Available since: 2.3.0

Parameters

  • origin : Object

    The Observable whose events this object is to relay.

  • events : String[]

    Array of event names to relay.

  • prefix : String (optional)

    A common prefix to prepend to the event names. For example:

    this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
    

    Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.

Returns

  • Object

    A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:

    this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
    

    Can be undone by calling

    Ext.destroy(this.storeRelayers);
    

    or

    this.store.relayers.destroy();

                          // alerts "Meeeeoooowwww"

As of 4.1, direct use of this method is deprecated. Use Ext.define instead:

Ext.define('My.CatOverride', {
    override: 'My.Cat',

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

The above accomplishes the same result but can be managed by the Ext.Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class (My.Cat).
