如何使用C ++/VC ++代码平移窗口 [英] How to Pan a window using C++/VC++ code

问题描述

你好！

在MFC/Win32中是否有任何API可以像在Auto cad或Pro-E中那样平移窗口.

如果需要平移，那就是在绘制圆后，如何在VC ++中做到这一点

谢谢，

问候，
Maha

With this functionality you can scroll a part of your window in any direction you want. The part of the screen that becomes invalid has to be explicitely invalidated so that it causes a repaint for that part of the screen only.
Your paint routine should be written as such that it is smart enough to only paint those elements on the screen that have become invalid. This way you can make your screen seem like it is moving without annoying flickering.
