我创建了一个菜单:
menu = Menu.createMenu(parent, get_entries());
menu.labelField = "@label";
...
menu.show(position.x, position.y);
如何检查菜单是否仍然显示?
答案 0 :(得分:0)
收听menu
的{{3}}事件;隐藏菜单或子菜单时调度它。在事件监听器内部,检查是否event.target == event.currentTarget
。如果它们相等,则意味着菜单只是隐藏 - 否则意味着菜单仍然可见,但其中一个子菜单只是隐藏。
menu.addEventListener(MeuEvent.MENU_HIDE, onHide);
private function onHide(e:Event):void
{
if(e.target == e.currentTarget)
trace("The main menu was just hidden");
else
trace("main menu is still visible, the submenu "
+ e.target + " was just hidden");
}
