Doug:

I'm sure the wxHeads will reply giving you the answer you seek, this is just
a cautionary point about user interfaces in general -- it may not apply in
the specific case you have in mind.

If you are going to choose a single event to action on a button, it's better
to use the button UP rather than button Down event. There's nothing worse
than an interface that won't let you change your mind, so that a little
unintentional extra pressure on the mouse button is all you need for
disaster. On the better (more "comfortable") user interfaces you should find
you can click on a button then change your mind, and move the cursor off the
button before releasing the mouse button, without selecting any action.
