Question

I’m building a custom component and I need to convert the event that is passed to the method into a mouse event. I can do this but it is telling me that I’m getting a null reference of an object. Here is how I am calling it.

public function dragStart(e:MDIWindowEvent): void {
    var mouse:MouseEvent = (e.currentTarget as MouseEvent);
    trace(mouse.localX);//<-----Null Error
}

How can I go by converting the MDIWindowEvent to a MouseEvent? If I can at that.

Answer 1

You are casting the Event target not the event it won’t work.
Also you can’t cast an MDIWindowEvent as a MouseEvent.

What you can try is:

public function dragStart(e:MDIWindowEvent): void {
    trace(e.currentTarget.mouseX);
}
