I'm sorry, I forgot perhaps code that may be causes this error:
Boolean ApplicationHandleEvent(EventPtr event)
{
FormPtr frm;
Word formId;
Boolean bHandled=false;
if (event->eType==frmLoadEvent)
{
formId=event->data.frmLoad.formID;
frm=FrmInitForm(formId);
FrmSetActiveForm(frm);
switch (formId)
{
case MainForm:
FrmSetEventHandler
(frm,MainFormHandleEvent);
break;
}
bHandled=true;
}
return bHandled;
}
static Boolean MainFormHandleEvent(EventPtr event)
{
FormPtr frm;
Boolean handled = false;
EventType newEvent;
switch(event->eType)
{
case frmOpenEvent:
frm=FrmGetActiveForm();
FrmDrawForm(frm);
handled=true;
break;
case ctlSelectEvent:
switch( event->data.ctlEnter.controlID )
{
case MainExitButton:
MemSet(&newEvent, sizeof(EventType), 0);
newEvent.eType = appStopEvent;
EvtAddEventToQueue(&newEvent);
handled = true;
break;
}
handled=true;
break;
case menuEvent:
MenuEraseStatus(CurrentMenu);
frm=ProcesarComando(event->data.menu.itemID);
handled = true;
break;
}
return handled;
}
