When migrating, RsrcToRcp didn't move the VISIBLEITEMS part to the RCP file, so my
lists were not showing anything. Glad it was simple!

Subject: Unexpected behavior with PopupTriggers after migrating to
rcp-based resources
Hi all.
I have recently migrated my resource to use rcp files. I have discovered that my
popup triggers no longer work as they once did. In fact, setting a break point in the
handler shows that popSelect events never occur. I'm sure I've done something silly,
but I can't see it.
It seems that as configured I need to be owner-drawn now, whereas with the
constructor-based resources the OS handled it for me....
I find is strange that the behavior has changed since moving to RCP-based resources...
Here's the rcp for the popup trigger:
...
POPUPTRIGGER "HH:MM am/pm" ID SetupTimeFormatPopTrigger AT (62 32 80 12) USABLE
LEFTANCHOR
POPUPLIST ID SetupTimeFormatPopTrigger SetupTimeFormatList
LIST "" ID SetupTimeFormatList AT (62 50 84 09) NONUSABLE
...
The popup trigger is initialized like this in the form's init function:
// init time format
pref = PrefGetPreference(prefTimeFormat);
GetStringListFromListRes(TimeFormatsStringList, &timeListP, &numStrings);
listP = (ListType*)GetObjectPtr(SetupTimeFormatList);
ctlP = (ControlType*)GetObjectPtr(SetupTimeFormatPopTrigger);
LstSetListChoices(listP, timeListP, numStrings);
LstSetSelection(listP, (Int16)TimeMap[pref].listIndex);
selectionTextP = LstGetSelectionText(listP, (Int16)TimeMap[pref].listIndex);
CtlSetLabel(ctlP, selectionTextP);
// The TimeMap is a little data structure that maps the formats we support to the
formats the os defines.
// All pointers and lists are ok in the debugger.
The handler looks like this:
static Boolean SetupFormHandleEvent(EventPtr eventP)
{
Boolean handled = false;
FormPtr frmP = NULL;
MemHandle recH = NULL;
switch (eventP->eType)
{
case nilEvent:
{
UInt32 time;
DateTimeType dt;
time = TimGetSeconds();
TimSecondsToDateTime(time, &dt);
UpdateTime(&dt);
UpdateDate(&dt);
}
break;
case ctlSelectEvent:
switch(eventP->data.ctlSelect.controlID)
{
case SetupTimeEditSelTrigger:
OnTimeTriggerSelect();
handled = true;
break;
case SetupDateEditSelTrigger:
OnDateTriggerSelect();
handled = true;
break;
}
break;
case popSelectEvent:
switch(eventP->data.popSelect.controlID)
{
case SetupDateFormatPopTrigger:
OnDateFormatPopTrigger();
handled = true;
break;
case SetupTimeFormatPopTrigger:
OnTimeFormatPopTrigger();
handled = true;
break;
case SetupLanguagePopTrigger:
if(OnLanguagePopTrigger())
{
verShown_g = false;
ret = SetLanguage();
// This code will only execute on <4.0 OS.
FrmEraseForm(thisForm_g);
FrmDeleteForm(thisForm_g);
// Clean up some memory used
FreeStringListFromRes(&langListP);
FreeStringListFromRes(&dateListP);
FreeStringListFromRes(&timeListP);
if(langMapP)
{
MemPtrFree(langMapP);
langMapP = NULL;
}
thisForm_g = FrmInitForm(SetupForm);
FrmSetActiveForm(thisForm_g);
FrmSetEventHandler(thisForm_g, SetupFormHandleEvent);
SetupFormInit(thisForm_g);
}
handled = true;
break;
}
break;
case MSG_NEDGOKEYEVENT:
// Get values from form and save them
done_g = true;
handled = true;
break;
default:
break;
}
return handled;
}
The popSelect event is never fired....
Thanks,
Kevin
