There doesn't seem to be an event to tell me when the user
finishes sliding the track bar.

Any clues on this one?

Hi Chris,

I encountered that problem too. Here is the way I solved it in delphi :

//file: exttrackbar.pas (Extended Trackbar by CyberWolf)
//
// If you use it, please send me your comments, suggestions
// or modifications at CyberWolf_cool@hotmail.com !
//
//
unit ExtTrackBar;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, CommCtrl, ComCtrls;

type
  TExtendedTrackBar = class(TTrackBar)
  private
    { Private declarations }
  protected
    { Protected declarations }
  public
    procedure ClearTics;
  published
    property OnMouseDown;
    property OnMouseMove;
    property OnMouseUp;
  end;

procedure Register;

implementation

procedure TExtendedTrackBar.ClearTics;
begin
SendMessage(Handle,TBM_CLEARTICS,LongInt(True),0);
end;

procedure Register;
begin
  RegisterComponents('CyberWolf', [TExtendedTrackBar]);
end;

end.



As you can see I fixed the bug of the missing ClearTics function too! To use this new trackbar, simply install the new component and then use this one instead of the original TTrackbar!

I hope this will solve your problem,

See ya,

CyberWolf
