Greetings,
I *learned from example* using the Scrollbar routines from the PalmOS4
source code, and implemented a SclHandleEvent for my own custom scrollbar
control. [This is for a Satellite Forms extension.] This has worked great
under previous PalmOS versions, but now that a version of SatForms that
supports PalmOS 5 is finally available, I find that the code doesn't quite
work on the OS5 Simulator.
Specifically, when I monitor the event queue (nice feature in PalmSim!), I
find that when I tap on the scrollbar, the expected sclEnterEvent is not
generated, but a nilEvent is queued instead. Thus, the scrollbar doesn't
act on the pen taps.
Strangely, if I use a status display function to show me what the eventtype
of my new event is, it is indeed a sclEnterEvent as expected. But, the
PalmSim event monitor shows (and the OS sees) only a nilEvent.
Here's the snippet of code I am using in the SclHandleEvent:
if (event->eType == penDownEvent)
{
if (RctPtInRectangle (event->screenX, event->screenY, &bar->bounds))
{
// newEvent = *event;
MemSet (&newEvent, sizeof(EventType), 0);
newEvent.eType = sclEnterEvent;
newEvent.data.sclEnter.scrollBarID = bar->id;
newEvent.data.sclEnter.pScrollBar = bar;
EvtAddEventToQueue (&newEvent);
handled = true ;
MyShowStatus("sclEvt type:", newEvent.eType);
}
}
Can anyone suggest why this sclEnterEvent is being turned into a nilEvent in
the queue, and better yet what I can do to work around the problem?
