Steve,
ctlRepeatEvent is generated by repeat buttons (and scroll bars) for every
interval (I think its 9/100ths of a second) that the pen remains within the
bounds of the control. If you have multiple repeat buttons, you can check
which one is being tapped by examining the controlID member of the event
structure. Then, you handle each event by updating a label, or doing
whatever it is you need to do on the event. Here's a code snippet from our
book:
MainFormEventHandler (EventPtr eventP)
{
Boolean handled = false;
switch (eventP->eType)
{
case ctlRepeatEvent:
{
FormPtr formP = FrmGetActiveForm ();
handled = MainFormButtonHandler (formP, eventP);
break;
}
default:
{
break;
}
}
return handled;
}
Boolean
MainFormButtonHandler (FormPtr formP, EventPtr eventP)
{
Boolean handled = false;
switch (eventP->data.ctlEnter.controlID)
{
case MainAgeUpRepeating:
{
// Decrement the age
if ( s_Age > 22 )
{
Word wIDAge = FrmGetObjectIndex (formP, MainAgeLabel );
ControlPtr pCtlAge = (ControlPtr) FrmGetObjectPtr (formP, wIDAge);
char szAge[5];
s_Age--;
StrPrintF ( szAge, "%d", s_Age );
FrmHideObject (formP, wIDAge);
FrmCopyLabel (formP, MainAgeLabel, szAge);
FrmShowObject (formP, wIDAge);
}
break;
}
}
return handled;
}
