alex, did you solve your problem ? i'm looking for the same info - as far as i went i didn't get much !!!!
i can create the button, i see the button, but it only reacts once in a while to user's click (actually, once (but not the 1st time) and then no more)
i'm trying to attach some kind of a "control container" (ah ah ah haven't found yet which class is more suitable to handle that !!!) to my window, but i'll be stuck very soon :-(
can someone help ? pliz ?
