I want to do is to do some animation.
In the ideal world I would set up a "DanEvent" that would be generated every X ticks
of the clock. I understand how this can be done with "nilEvents" but the facts remain
that
my main form handler (the stub of which was generated by codewarrior) looks like this:
(My comments are in UPPERCASE)
All I wanted to do here was to have a button on my form generate the first nilEvent
and have
each nilEvent following this be generated by a call to evtGetEvent from within
nilEvent case.
I KNOW that I should be checking on the time and making sure that the nill events I
receive
are "mine" but I figured that for now I'd be happy with getting more nilEevents than I
was expecting...
but quite the opposite happens! I get NO nilEvents! (I am indicating that a nilEvent
has occured
by printing out the number of ticks using WinDrawChars().
Where are all the nil Events going? I've tried messing with the timeout value on the
evtGetEvent
call to no avail!
static Boolean MainFormHandleEvent(EventPtr eventP)
{
Boolean handled = false;
FormPtr frmP;
Word wIDMainToggleCheckBox, wIDMainTimeField;
ControlPtr pCtlMainToggleCheckBox;
static int iToggle=0;
FieldPtr pCtlField;
ULong ulongCurrentTicks;
char cFubar[8];
switch (eventP->eType)
{
case menuEvent:
return MainFormDoCommand(eventP->data.menu.itemID);
case frmOpenEvent:
frmP = FrmGetActiveForm();
MainFormInit( frmP);
FrmDrawForm ( frmP);
handled = true;
break;
case ctlSelectEvent:
if (eventP->data.ctlEnter.controlID == MainGoButton) {
//USER HAS PUSHED THE GO BUTTON!
EvtGetEvent(eventP, 100);
}
break;
case nilEvent:
//NEVER GETS HERE! (EXCEPT UNDER POSE)
ulongCurrentTicks=TimGetTicks();
StrIToA(cFubar,ulongCurrentTicks);
WinDrawChars(cFubar,StrLen(cFubar),100,100);
EvtGetEvent(eventP, 100);
handled = true;
break;
default:
break;
}
return handled;
}
