Example
The following example creates a menu with two menu items, the second of which is a check
box menu item. The example calls the method to put the check
setMenuItemSelected()
box menu item in a selected state.
You first drag a Menu component to the library and then add the following code to Frame 1:
/**
Requires:
- Menu component in library
*/
import mx.controls.Menu;
// Create an XML object to act as a factory.
var my_xml:XML = new XML();
// The item created next does not appear in the menu.
// The createMenu() method call (below) expects to
// receive a root element whose children will become
// the items. This is just a simple way to create that
// root element and give it a convenient name.
var menuDP_obj:Object = my_xml.addMenuItem("XXXXX");
// Add the menu items.
menuDP_obj.addMenuItem({label:"1st Item"});
menuDP_obj.addMenuItem({type:"check", label:"2nd Item"})
// Create the Menu object.
var my_menu:Menu = Menu.createMenu(this, menuDP_obj);
var myItem = my_menu.getMenuItemAt(1);
my_menu.setMenuItemSelected(myItem, true);
// Show and position the menu.
my_menu.show(100, 20);
Menu.setMenuItemSelected() 931
