Panning and Scrolling in Windows

Last reviewed: November 2, 1995

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) for Windows versions 3.0 and 3.1

Microsoft Win32 Application Programming Interface (API) included with:

    - Microsoft Windows NT versions 3.5 and 3.51
    - Microsoft Windows 95 version 4.0

When using bitmaps, the mapping mode is ignored and physical units (in other words, MM_TEXT pixels) are used. It is not necessary to use the extent/origin routines to keep track of the logical origin.

If scrolling is desired and if there are no child windows in the client area, it is best to BitBlt the client area to scroll it, and PatBlt the uncovered area with the default brush.
