Correct, assuming you're trying to implement your own gadgets.

Windows eats most of the events itself, so you can write such
handlers on Windoze gadgets.  I have a plan for opening up
these natvie Windoze gadgets such that some events will be
noticeable, but I haven't gotten around to doing it.  Note that
it won't be portable!

I think that when you design the Windows bitmap, there is a
"transparent" color you can use to do it.  That's what the
Functional Developer icons in the environment use.
