In this case the system does the whole job for you. You just have to set the
trigger label text and afterwards get a pointer to the changed label text.
You don't need code to trigger and hide the popup list.
1. In the resource editor (i.e. constructor) attach the list to the popup
trigger
2. In the code assign a dynamic array to the list in the FormInit routine.
lst = GetObjectPtr (MainList);
// load popup list with db records
(loop through records to load array...)
LstSetListChoices (lst, &listItems[0], numRecords);
LstSetHeight (lst, visibleRows);
LstSetSelection (lst, currentRow);
FrmDrawForm (frm);
3. In the FormHandleEvent routine get the changed label text
case ctlSelectEvent:
switch (event->data.ctlSelect.controlID) {
case MainOKButton:
str = CtlGetLabel (GetObjectPtr (MainListPopTrigger));
and that's all you have to do!
