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 <a href="output/Ext.Toolbar.html" ext:cls="Ext.Toolbar">Ext.Toolbar</a>, <a href="output/Ext.Button.html" ext:cls="Ext.Button">Ext.Button</a>
and <a href="output/Ext.menu.Menu.html" ext:cls="Ext.menu.Menu">Ext.menu.Menu</a> components).</p>
<p>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).</p>
Example usage:<br>
<pre><code><i>// Define the shared action. Each component below will have the same
</i>
<i>// display text and icon, and will display the same message on click.
</i>
<b>var</b> action = <b>new</b> Ext.Action({
<a href="output/Ext.Action.html#Ext.Action-text" ext:member="text" ext:cls="Ext.Action">text</a>: <em>'Do something'</em>,

Ext.Msg.alert(<em>'Click'</em>, <em>'You did something.'</em>);
},
<a href="output/Ext.Action.html#Ext.Action-iconCls" ext:member="iconCls" ext:cls="Ext.Action">iconCls</a>: <em>'<b>do</b>-something'</em>,
