That was it! Thank you Scott. I don't know when, if ever, I would have
noticed that I was returning true for *any* ctlSelectEvent. I had a button
and a checkbox on that form and the flawed logic I had was:
// bad code...
case ctlSelectEvent:
If (eventP->data.ctlEnter.controlID == TheButton)
doButtonStuff();
else if (eventP->data.ctlEnter.controlID == TheCheckbox)
doCheckBoxStuff();
handled = true;
break;
I changed the code so handled is true only if I do the button or the
checkbox and now the list opens when I tap the trigger.
// better code...
case ctlSelectEvent:
If (eventP->data.ctlEnter.controlID == TheButton)
{
doButtonStuff();
handled = true;
}
else if (eventP->data.ctlEnter.controlID == TheCheckbox)
{
doCheckBoxStuff();
handled = true;
}
break;
Thanks to everyone who suggested possible fixes for this problem.
