Ext.grid.feature.Grouping

Hierarchy

Subclasses

Files

This feature allows to display the grid rows aggregated into groups as specified by the Ext.data.Store.groupers specified on the Store. The group will show the title for the group name and then the appropriate records for the group underneath. The groups can also be expanded and collapsed.

Extra Events

This feature adds several extra events that will be fired on the grid to interact with the groups:

Menu Augmentation

This feature adds extra options to the grid column menu to provide the user with functionality to modify the grouping. This can be disabled by setting the enableGroupingMenu option. The option to disallow grouping from being turned off by the user is enableNoGroups.

Controlling Group Text

The groupHeaderTpl is used to control the rendered title for each group. It can modified to customized the default display.

Example Usage

var store = Ext.create('Ext.data.Store', {
    storeId:'employeeStore',
    fields:['name', 'seniority', 'department'],
    groupField: 'department',
    data: {'employees':[
        { "name": "Michael Scott",  "seniority": 7, "department": "Management" },
        { "name": "Dwight Schrute", "seniority": 2, "department": "Sales" },
        { "name": "Jim Halpert",    "seniority": 3, "department": "Sales" },
        { "name": "Kevin Malone",   "seniority": 4, "department": "Accounting" },
        { "name": "Angela Martin",  "seniority": 5, "department": "Accounting" }
    ]},
    proxy: {
        type: 'memory',
        reader: {
            type: 'json',
            root: 'employees'
        }
    }
});

Ext.create('Ext.grid.Panel', {
    title: 'Employees',
    store: Ext.data.StoreManager.lookup('employeeStore'),
    columns: [
        { text: 'Name',     dataIndex: 'name' },
        { text: 'Seniority', dataIndex: 'seniority' }
    ],
    features: [{ftype:'grouping'}],
    width: 200,
    height: 275,
    renderTo: Ext.getBody()
});

Note: To use grouping with a grid that has locked columns, you need to supply the grouping feature as a config object - so the grid can create two instances of the grouping feature.

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 Components

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

This object holds a key for any event that has a listener. ...

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);

    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();
      

    Fires

      Overrides: Ext.AbstractComponent.addListener

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

      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'); }
        });
        

        And when those listeners need to be removed:

        Ext.destroy(this.btnListeners);

          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.

          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. 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: [{

                                                      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

                                                • 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();

                                                                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.

                                                                • events : String[]

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