Question

I am creating modal popup canvas window in a parent page. When I close the popup how do we get notification in parent screen that child popup is just closed. Any event for that ?

Answer 1

The code to show your popup:

var popup:MyPopup = new popup:MyPopup();

popup.addEventListener(CloseEvent.CLOSE, function(evt) { 
    PopUpManager.removePopUp(popup);
});

PopUpManager.addPopUp(popup, this, true);

Inside your MyPopup class, you will have a button for closing the popup. Simply hook the click event to publish a “CLOSE” event:

<s:Button Label="X" click="dispatchEvent(new CloseEvent(CloseEvent.CLOSE));" />

I prefer this mechanism over having the MyPopup object calling PopUpManger.removePopUp (as @Fank is suggesting) because it couples the MyPopup component to the PopUpManager which I don’t like. I’d prefer the user of MyPopup to decide how to use the component.

Honestly, though, these are two very similar mechanisms to perform the same end goal.
