This is an example of putting some text in the fixed cell..
You can use a Unicode character for a more pronounced look.
procedure TForm1.StringGrid1SelectCell(Sender: TObject; aCol, aRow: Integer;
var CanSelect: Boolean);
begin
with TstringGrid(Sender) do
Begin
Cells[0,Row] := ''; // clear this one first because its still sitting on the last row
Cells[0,ARow] := '>';
end;
end;
This is a copy and paste from a Delphi app, not sure if this will work in Laz..
