вот вспомогательный класс, который вам поможет (протестирован только во Flex 4, но, вероятно, может быть изменен и для Flex 3):
</p>
<pre><code>import flash.display.DisplayObject;
import flash.events.Event;
import flash.events.MouseEvent;
import mx.core.mx_internal;
import mx.managers.ISystemManager;
import mx.managers.systemClasses.ActiveWindowManager;
use namespace mx_internal;
public class PopupHelper
{
private var popup : DisplayObject;
private var systemManager : ISystemManager;
public function PopupHelper(popup : DisplayObject, systemManager : ISystemManager) : void
{
this.popup = popup;
this.systemManager = systemManager;
}
public function forceToFront() : void
{
systemManager.addEventListener(MouseEvent.MOUSE_DOWN, onSystemMouseDown);
popup.addEventListener(Event.REMOVED_FROM_STAGE, onPopupRemoved)
}
private function onSystemMouseDown(e : MouseEvent) : void
{
bringToFront(popup);
}
private function onPopupRemoved(e : Event) : void
{
popup.removeEventListener(Event.REMOVED, onPopupRemoved);
systemManager.removeEventListener(MouseEvent.MOUSE_DOWN, onSystemMouseDown);
}
private function bringToFront(popup : DisplayObject) : void
{
var windowManager : ActiveWindowManager = systemManager.getImplementation("mx.managers::IActiveWindowManager") as ActiveWindowManager;
var index : int = systemManager.getChildIndex(popup);
var newIndex : int = index;
var n : int = windowManager.forms.length;
for (var j : int = 0; j < n; j++)
{
var f : DisplayObject = windowManager.forms[j];
if (systemManager.contains(f))
if (systemManager.getChildIndex(f) > index)
newIndex = Math.max(systemManager.getChildIndex(f), newIndex);
}
if (newIndex > index)
{
systemManager.setChildIndex(popup, newIndex);
}
}
}
Вот пример теста:
</p>
<pre><code> import helperClasses.PopupHelper;
import mx.managers.PopUpManager;
import spark.components.TitleWindow;
public function showPopup() : void
{
var popup1 : TitleWindow = new TitleWindow();
popup1.title = "Popup 1";
new PopupHelper(popup1, systemManager).forceToFront();
var popup2 : TitleWindow = new TitleWindow();
popup2.title = "Popup 2";
PopUpManager.addPopUp(popup1, this, false);
PopUpManager.addPopUp(popup2, this, false);
PopUpManager.bringToFront(popup1);
popup1.x = 20;
popup1.y = 20;
}
