Class Ext.Action

Package:Ext
Defined In:Action.js
Class:Action
Extends:Object

An Action is a piece of reusable functionality that can be abstracted out of any particular component so that it -can be usefully shared among multiple components. Actions let you share handlers, configuration options and UI -updates across any components that support the Action interface (primarily Ext.Toolbar, Ext.Button -and Ext.menu.Menu components).

-

Aside from supporting the config object interface, any component that needs to use Actions must also support -the following method list, as these will be called as needed by the Action class: setText(string), setIconCls(string), -setDisabled(boolean), setVisible(boolean) and setHandler(function).

-Example usage:
-
// Define the shared action.  Each component below will have the same

-// display text and icon, and will display the same message on click.

-var action = new Ext.Action({
-    text: 'Do something',
-    handler: function(){
-        Ext.Msg.alert('Click', 'You did something.');
-    },
-    iconCls: 'do-something',
-    itemId: 'myAction'
-});
-
-var panel = new Ext.Panel({
-    title: 'Actions',
-    width: 500,
-    height: 300,
-    tbar: [
-        // Add the action directly to a toolbar as a menu button

-        action,
-        {
-            text: 'Action Menu',
-            // Add the action to a menu as a text item

-            menu: [action]
-        }
-    ],
-    items: [
-        // Add the action to the panel body as a standard button

-        new Ext.Button(action)
-    ],
-    renderTo: Ext.getBody()
-});
-
-// Change the text for all components using the action

-action.setText('Something else');
-
-// Reference an action through a container using the itemId

-var btn = panel.getComponent('myAction');
-var aRef = btn.baseAction;
-aRef.setText('New text');
