Where do you allocate AllItems itself? In any event, you need to free it,
together with all the chunks it points to. You do this when you have
finished displaying your list. You might want to add a FrmCloseEvent to your
event loop for this purpose.
But you would be much better off using a callback function to draw the items
in your list. It might seem complicated, but it would save you an awful lot
of hassle, viz:
static void DrawItem(LInt p,
RectanglePtr r, CharPtr *dummy){
DrawBytes(p, ReturnSelection(1, p), 0, r);
}
LstSetDrawFunction(List, DrawItem);
And we are done. Here LInt is either Int or UInt, depending on your level of
PalmOS.
