Implement XP style scrollbar by self-draw
Sample Image - self-draw_XPScrollbar.jpg

Introduction

One of my recent projects needed to beautify UI, but when the app does not run on WinXP, the intrinsic scrollbar of common controls is too ugly. So I use self-draw CScrollWnd instead.

At present, only VSCROLL is supported. HSCROLL will be added when I have time to do it, and any help will be appreciated (you can add it by yourself).

Trick

The biggest problem to implement a scrollbar is to locate thumb properly. To solve this problem, I have used many ways, but at the end, a very convenient and reliable method was found: step by step approach.

Code

void CScrollWnd::MoveThumb(CPoint ptOffset)

{ if(!IsMouseInRange(WM_VSCROLL))
  return;
 CPoint ptCursor;
 GetCursorPos(&ptCursor);
 ScreenToClient(&ptCursor); 

 CPoint ptCurPos = ptCursor;
 int nMaxTimes=200;

 int nTimes = 0;
 int nStep = 1;//accuracy

 CPoint ptNewPos = ptOffset + GetRect(HT_THUMB).CenterPoint();
 while(abs(ptNewPos.y - ptCurPos.y)>nStep && nTimes++<nMaxTimes)
 {
  BOOL bDirDown = ptCurPos.y>ptNewPos.y;
  NotifyBuddy(WM_VSCROLL,MAKEWPARAM(bDirDown?SB_LINEDOWN:SB_LINEUP,0));
  
  UpdateScrollBar();
  ptNewPos = ptOffset + GetRect(HT_THUMB).CenterPoint();
 }
}

See the attached source code for more details.
