Hey,

how could i activated the scrollrulers for the sCheckListBox?

I have activated and deactivated the property AutoHideScroll, but with the same result -> no horizontal ruler.

Even when the text exceeds the right edge, only the vertical ruler appears.

See picture, above design view, bottom run view.

Best regards,

If you need to use a horz scrollbar then try this code:

Code:

procedure HorScrollBar(ListBox: TListBox);
var
i, w: Integer;
maxwidth: Integer;
begin
maxwidth := 0;
// Get largest item
for i := 0 to ListBox.Items.Count – 1 do
with ListBox do begin
w := Canvas.TextWidth(Items);
if w > maxwidth then
maxwidth := w;
end;

SendMessage(ListBox.Handle, LB_SETHORIZONTALEXTENT, maxwidth + GetSystemMetrics(SM_CXFRAME), 0);
SetWindowLong(ListBox.Handle, GWL_STYLE, GetWindowLong(ListBox.Handle, GWL_STYLE) or WS_HSCROLL);
SetWindowPos(ListBox.Handle, 0, 0, 0, 0, 0, SWP_NOSIZE or SWP_NOMOVE or SWP_NOACTIVATE or SWP_NOZORDER or SWP_NOCOPYBITS or SWP_NOSENDCHANGING or SWP_NOREPOSITION or SWP_FRAMECHANGED);
end;

I found it in the Net for standard ListBox, bot TsCheckListBox should work with this code too.

Hey,

thanks for the example.

Yes it works (i have a made similar one).

But i thought that the property AutoHideScroll should do that for me.
