TTMSFNCTrackBar

The TTMSFNCTrackBar is a component that works like a TTrackBar, but also introduces other capabilities such as orientation, optionally visible and positionable text, plus/minus buttons and more.

The Thumb, TickMarks, plus/minus Buttons, and the Line are all customizable via the Appearance property:

procedure TForm1.Button1Click(Sender: TObject);
begin
 TMSFNCTrackBar1.Appearance.LineWidth := 10;
 TMSFNCTrackBar1.Appearance.LineFill.Color := gcWhitesmoke;
 TMSFNCTrackBar1.Appearance.ThumbShape := tsEllipse;
 TMSFNCTrackBar1.Appearance.ThumbWidth := 10;
 TMSFNCTrackBar1.Appearance.ThumbHeight := 10;
 TMSFNCTrackBar1.Appearance.ThumbFill.Color := gcDodgerblue;
 TMSFNCTrackBar1.Appearance.ButtonShape := bsRounded;
 TMSFNCTrackBar1.Appearance.TickMarkPosition := tmpBoth;
 TMSFNCTrackBar1.Appearance.TickMarkDivision := 10;
end;
