Scrolling Support for ATL Composite Controls

Here's a class that I wrote that adds scrolling support to any ATL Composite Control.

The following steps are needed to add scrolling...

  1. Include the ScrollImpl.h file
  2. #include "ScrollImpl.h"
  3. Add CScrollImpl to your inheritance tree
  4. public CScrollImpl
  5. Add the following entry to your Message Map
  6. CHAIN_MSG_MAP(CScrollImpl)
  7. Add a message handler for WM_INITDIALOG and add the following line to OnInitDialog...
  8. SetScrollSize( m_hWnd, xScrollPos, yScrollPos );
  9. Set xScrollPos to the position that you want horizontal scrolling to start and yScrollPos for the position you want vertical scrolling to start.
I've attached a sample workspace that contains the ScrollImpl.h file, a project with a composite control that supports scrolling and an MFC container for the control.
