HI
I've tested tScrollBar and I notice that HScroll is wrong in WIN32CALLBACK.INC musn't call in:

Function WindowProc(Window: HWnd; Msg: UInt;
  WParam: WParam; LParam: LParam): LResult; stdcall;
 WM_HSCROLL:
    Begin
      ;
Win32Def.ScrollWindow(Window,Position - NewPos,0,nil,@R);
    ^^^ in this cause I can't call CNHScroll

this section should be done similary to WM_LBUTTONDOWN: (call LCL) and rest of code move to STDCTRLS.PP

Do you want to handle CN_HSCROLL? What is the purpose?

Micha.

I have removed the interface independant code. I think the code should be moved to IntSendMessage3 in win32object.inc, investigating...

I have form divide to two panel, and only one must be scrolled

now in tScrollBar is CNHScroll whitch invoke fonscroll, but this not work, because handle of WM_HSCROLL is bad, as I say before
