I thought about that and have tried that, still nothing.
I also tried commenting out the MemHandleFree line to see if it would
crash... which it isn't doing either.
So after calling this function, I get no error, and no data showing up in
the list.
I am at a total loss as to what is going on. I thought it might have
something to do with the frmP and or lstP so have made a few changes as
follows:
static char* gPlateString =
"PL3/16x\0PL1/4x\0PL5/16x\0PL3/8x\0PL1/2x\0PL5/8x\0";
static char** gListString;
MemHandle gStringH;
static Boolean PopulateList(FormType* frmP, ListType* lstP)
{
gStringH = SysFormPointerArrayToStrings(gPlateString, 6);
gListString = (char**)MemHandleLock(gStringH);
LstSetListChoices(lstP, gListString, 6);
MemHandleUnlock(gStringH);
return true;
}
...
case frmCloseEvent:
MemHandleFree(gStringH);
break;
