Popup Scopes and easy way to close all open Popups

While creating popup we can define the scope of the popup (i.e where the popup list is maintained ) by defining detail parameter while creating or adding a popup. The PopUpManagerChildList class defines constants for the detail property for the PopUpManager addPopUp() and createPopUp() methods.

systemManager isntance has a "popUpChildren" variable which maintains list of all popups created in PopupManagerChildList.POPUP scope. Thus we can easily remove all the popups created in this scope using the following snippet:

while (systemManager.popUpChildren.numChildren > 0){
PopUpManager.removePopUp(IFlexDisplayObject(systemManager.popUpChildren.getChildAt(0)));
}


While creating popup use the following signature:

        PopUpManager.createPopUp(this, class ,modalValue,PopUpManagerChildList.POPUP) ;
or
        PopUpManager.addPopUp(popupInstance,this,false,PopUpManagerChildList.POPUP);
