Thank you for the help. I have a "dragEnterHandler" function which is called upon the main container's "DragEvent.DRAG_ENTER" event. The dragEnterHandler is the only place where acceptDragDrop is called, but that handler is only called when I'm on the left side of the container. I'm looking through the Flex source now to see when exactly the DRAG_ENTER event is dispatched.
It's worth noting that the dead zone changes as the size of the control changes. It's not half of the container size, but around 60% of the length. Thank you again for your assistance. --- In [email protected], Alex Harui <aha...@...> wrote: > > Double check your logic about when you call acceptDragDrop > > Alex Harui > Flex SDK Developer > Adobe Systems Inc.<http://www.adobe.com/> > Blog: http://blogs.adobe.com/aharui > > From: [email protected] [mailto:[email protected]] On > Behalf Of bgamblin > Sent: Tuesday, November 10, 2009 8:54 AM > To: [email protected] > Subject: [flexcoders] Re: Odd DragOver Problem > > > > Well, I hate to sound ditzy here, but I didn't actually fix all the problems > by changing the background color.
