I am not sure if this is the *correct* way of doing this.. nor am I sure
that if this
works.. but you can try this.
Although there is no LstGetListChoices ( ListPtr) function to go with
LstSetListChoices ( ... ), you can see your gStringArray in
listP->itemsText.
Maybe you can do this?
case frmCloseEvent:
ListPtr listP = FrmGetObject ( frmP, FrmGetObjectIndex ( frmP,
DateUnmamed1118List ) );
if ( listP->itemsText )
{
MemPtrUnlock ( listP->itemsText );
MemPtrFree ( listP->itemsText );
}
or something along the way.. I feel like this might cause a crash
somewhere..
but I *might* work too...
If you get a chance to try it, let me know =)
