LstGetSelection() returns the index of the selected item in the list,
and LstGetSelectionText() returns the text value of the specified list
item.
I might define the list like this (I use PilRC; getting this into
Constructor should be pretty straightforward):
LIST "1" "2" "5" "10" "20" "50" "100" "200" ID LIDgain
AT (90 20 40 AUTO) VISIBLEITEMS 8
and in my code you might see
int getgain(ListPtr list)
{
int index;
char *text;
int gain;
index = LstGetSelection(list);
if (index < 0) // no item selected
gain = -1;
else
{
text = LstGetSelectionText(list, index);
gain = StrAToI(text);
}
return gain;
}
