        Fires

          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.

          This method has been deprecated since 2.0

          It's no longer needed to add events before firing.

          Parameters

          • eventNames : 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.

          ( eventName, [fn], [scope], [options], [order] )
          Appends an event handler to this object. ...

          Appends an event handler to this object. You can review the available handlers by looking at the 'events' section of the documentation for the component you are working with.

          Combining Options

          Using the options argument, it is possible to combine different types of listeners:

          A delayed, one-time listener:

          container.addListener('tap', this.handleTap, 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:

          container.addListener({
              tap  : this.onTap,
              swipe: this.onSwipe,
          
              scope: this // Important. Ensure "this" is correct during handler execution
          });
          

          One can also specify options for each event handler separately:

          container.addListener({
              tap  : { fn: this.onTap, scope: this, single: true },
              swipe: { fn: button.onSwipe, scope: button }
          });
          

          See the Events Guide for more.

          Parameters

          • eventName : String/String[]/Object

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

          • fn : Function/String (optional)

            The method the event invokes. 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.

            This object may contain any of the following properties:

            • scope : Object (optional)

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

            • delay : Number (optional)

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

            • single : Boolean (optional)

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

            • order : String (optional)

              The order of when the listener should be added into the listener queue.

              If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.

              Available options are before, current and after.

              Defaults to: current

            • buffer : Number (optional)

              Causes the handler to be 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.

            • element : String (optional)

              Allows you to add a listener onto a element of this component using the elements reference.

              Ext.create('Ext.Component', {
                  listeners: {
                      element: 'element',
                      tap: function() {
                          alert('element tap!');
                      }
                  }
              });
              

              All components have the element reference, which is the outer most element of the component. Ext.Container also has the innerElement element which contains all children. In most cases element is adequate.

            • delegate : String (optional)

              Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.

              // Create a container with a two children; a button and a toolbar
              var container = Ext.create('Ext.Container', {
                  items: [
                      {
                          xtype: 'toolbar',
                          docked: 'top',
                          title: 'My Toolbar'
                      },
                      {
                         xtype: 'button',
                         text: 'My Button'
                      }
                  ]
              });
              
              container.addListener({
                  // Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
                  delegate: 'button',
              
                  tap: function() {
                      alert('Button tapped!');
                  }
              });
              
          • order : String (optional)

            The order of when the listener should be added into the listener queue. Possible values are before, current and after.

            Defaults to: 'current'

              The item to which to add a listener/listeners.

            • eventName : Object/String

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

            • fn : Function (optional)

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

            • scope : Object (optional)

              If the eventName parameter was an event name, this is the scope in which the handler function is executed.

            • options : Object (optional)

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

                Call the original method that was previously overridden with override,

                This method is deprecated as callParent does the same thing.

                Ext.define('My.Cat', {
                    constructor: function() {
                        alert("I'm a cat!");

                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.

                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

                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".

                                  Fires the specified event with the passed parameters (minus the event name, plus the options object passed to addListener).

                                  The first argument is the name of the event. Every other argument passed will be available when you listen for the event.

                                  Example

                                  Firstly, we set up a listener for our new event.

                                  this.on('myevent', function(arg1, arg2, arg3, arg4, options, e) {
                                      console.log(arg1); // true
                                      console.log(arg2); // 2
                                      console.log(arg3); // { test: 'foo' }
                                      console.log(arg4); // 14
                                      console.log(options); // the options added when adding the listener
                                      console.log(e); // the event object with information about the event
                                  });
                                  

                                  And then we can fire off the event.

                                  this.fireEvent('myevent', true, 2, { test: 'foo' }, 14);
                                  

                                  An event may be set to bubble up an Observable parent hierarchy by calling enableBubble.

                                  Parameters

                                  • eventName : String

                                          Parameters

                                          • eventName : String/String[]/Object

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

                                          • fn : Function/String (optional)

                                            The method the event invokes. 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.

                                            This object may contain any of the following properties:

                                            • scope : Object (optional)

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

                                            • delay : Number (optional)

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

                                            • single : Boolean (optional)

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

                                            • order : String (optional)

                                              The order of when the listener should be added into the listener queue.

                                              If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.

                                              Available options are before, current and after.

                                              Defaults to: current

                                            • buffer : Number (optional)

                                              Causes the handler to be 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.

                                            • element : String (optional)

                                              Allows you to add a listener onto a element of this component using the elements reference.

                                              Ext.create('Ext.Component', {
                                                  listeners: {
                                                      element: 'element',
                                                      tap: function() {
                                                          alert('element tap!');
                                                      }
                                                  }
                                              });
                                              

                                              All components have the element reference, which is the outer most element of the component. Ext.Container also has the innerElement element which contains all children. In most cases element is adequate.

                                            • delegate : String (optional)

                                              Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.

                                              // Create a container with a two children; a button and a toolbar
                                              var container = Ext.create('Ext.Container', {

                                                          docked: 'top',
                                                          title: 'My Toolbar'
                                                      },
                                                      {
                                                         xtype: 'button',

                                              });
                                              
                                              container.addListener({
                                                  // Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
                                                  delegate: 'button',

                                                        As of 2.1, direct use of this method is deprecated. Use Ext.define instead:

                                                        Ext.define('My.CatOverride', {

                                                                var instance = this.callParent(arguments);
                                                        
                                                                alert("Meeeeoooowwww");
                                                        
                                                                return instance;
                                                            }
                                                        });
                                                        

                                                        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).
