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:
