Closing multiple popups in one shot

Here is the short example how to close all popups in one function.

It is very easy, but one rule shoul be followed - all popups shoul implement interface which contains single method.

package {
    import mx.core.IFlexDisplayObject;
    public interface iPopup extends IFlexDisplayObject {
        function closeWindow():void;
    }
}

Here is how you can implement interface from withing component:

<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" title="My Popup" implements="iPopup">

Your TitleWindow component in that case should implement closeWindow() method. Methot shoul be obviously public.

Here is the piece of code which actually closes all opened popups:

private function closeAllWindows():void {
    var popup:iPopup;
    var popupPackage:Array;
    for (var i:Number=0;i<systemManager.popUpChildren.numChildren;i++) {
        if(systemManager.popUpChildren.getChildAt(i) is iPopup) {
            popup = systemManager.popUpChildren.getChildAt(i) as iPopup;
            popup.closeWindow();
        }
    }
}

Please make sure that your code which opens popups sets the list in which your popup will be added:

PopUpManager.addPopUp(myTitleWindow, this, true,PopUpManagerChildList.POPUP);
