Is this a Headed Listbox in a thick-client window? If so, you can probably use the approach mentioned in the technical note: https://www.omnis.net/developers/resources/technotes/tngi0029.jsp
Something like this should work:
On evClick
Calculate hrzPos as (mouseover(kMHorz)-$cobj.$left)+($cobj.$hscroll-1)*8
Calculate columnWidths as $cobj.$columnwidths
Repeat
Calculate colNum as colNum+1
Calculate colRight as colRight+strtok(‘columnWidths’,”,”)
Until colRight>hrzPos
OK message {Value in clicked cell: [iList.[con(‘c’,colNum)]]}
