/** - * @class Ext.Action - *

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 {@link Ext.Toolbar}, {@link Ext.Button} - * and {@link 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({
-    {@link #text}: 'Do something',
-    {@link #handler}: function(){
-        Ext.Msg.alert('Click', 'You did something.');
-    },
-    {@link #iconCls}: 'do-something',
-    {@link #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');

/** - * @cfg {String} iconCls - * The CSS class selector that specifies a background image to be used as the header icon for - * all components using this action (defaults to ''). - *

An example of specifying a custom icon class would be something like: - *


-// specify the property in the config for the class:
-     ...
-     iconCls: 'do-something'
-
-// css class that specifies background image to be used as the icon image:
-.do-something { background-image: url(../images/my-icon.gif) 0 6px no-repeat !important; }
