The problem I'm running into is that when the user presses the mouse
button while in the control, the event handler gets called with a
kEventControlClick event, but it can't seem to get the proper control
part to determine if it should increment or decrement the value. What
it's doing is getting the mouse location parameter from the event,
converting it to local coordinates, then calling TestControl () to
find the part code. I've also tried FindControlUnderMouse (). Both of
those always return 0 for the part code. So why can't I get the proper
control part code in that situation? I'm setting the port to the
control's owner before calling GlobalToLocal () on the mouse point I
got from GetEventParameter (), so it should be the correct port and
the correct coords. In fact, checking the coords returned from
GlobalToLocal (), they are indeed inside the control's up or down
arrow.
Is this a compositing or non-compositing window? That would affect the
coordinate system that should be used (and the API).
