Re: [flexcoders] Re: How to tell when background image is clicked?
I'm afraid that doesn't do it either - the problem is, a Canvas with a
backgroundImage style set will never be the target of a click event, the
backgroundImage will always get in the way. I think I'm going to have to
refactor the whole thing at this point...

Hi Tim, unfortunately, that's exactly what happens :)
If you apply a backgroundImage, the target of the click event will be the
FlexLoader instance for that image, or in the case of a SWF, it'll be the
actual SWF instance. To make matters worse, the background image is (as
far
as I've been able to tell) indistinguishable from a regular child, in
that
it counts towards numChildren's value, returns true on contains() and
owns()
etc. I'm looking through the SDK source to try to find exactly where it's
added and how it manages to stay behind everything, but this is certainly
puzzling.

I'm pretty sure that the target will never be the background image

but rather the Canvas. One hack is to check the type:
