/** - * @class Ext.Action - * <p>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.Toolbar}, {@link Ext.button.Button} - * and {@link Ext.menu.Menu} components).</p> - * <p>Use a single Action instance as the config object for any number of UI Components which share the same configuration. The - * Action not only supplies the configuration, but allows all Components based upon it to have a common set of methods - * called at once through a single call to the Action.</p> - * <p>Any Component that is to be configured with an Action must also support - * the following methods:<ul> - * <li><code>setText(string)</code></li> - * <li><code>setIconCls(string)</code></li> - * <li><code>setDisabled(boolean)</code></li> - * <li><code>setVisible(boolean)</code></li> - * <li><code>setHandler(function)</code></li></ul>.</p> - * <p>This allows the Action to control its associated Components.</p> - * Example usage:<br> - * <pre><code> -// Define the shared Action.
