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');
-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; }
-{@link #handler} is executed. Defaults to this Button.
