Yes, exactly.
If I knew exactly what you are trying to do I can punch out an example.
if for example, you wanted a scrolling combobox using the simple form with no drop down and also give you an editor feature, you can attached that to the side of a combobox.Simple style.
You can stretch the box out of course to see the list of choices etc.
procedure TForm1.UpDown1ChangingEx(Sender: TObject; var AllowChange: Boolean;
NewValue: SmallInt; Direction: TUpDownDirection);
begin
Case Direction of
UpdUp:With ComboBox1 do
if ItemIndex >=0 Then ItemIndex := ItemIndex-1;
UpdDown:With ComboBox1 Do
If ItemIndex < Items.Count-1 Then ItemIndex := ItemIndex+1;
end;
end;
Something like that.
in that case, you do not associate the arrows with the combobox, just attached them.
