获取所有与我的窗口重叠的窗口 [英] Get all windows which overlap my window

问题描述

我想找到所有与我的窗口完全或部分重叠的窗口(位于其顶部). 作为一种特殊情况，如果我有两个窗口句柄(hWnd1和hWnd2)，我想确定hWnd2是否部分或完全重叠于hWnd1. 有问题的窗口是桌面窗口(不是同一过程中的子级/兄弟级).

I want to find all windows which entirely or partly overlap my window (are on top of it). As a special case, if I have two window handles (hWnd1 and hWnd2), I want to find if hWnd2 partly or completely overlaps hWnd1. The windows in question are desktop windows (not children/siblings in the same process).

推荐答案

使用GW_HWNDPREV重复调用GetWindow()来迭代可能与您重叠的窗口.使用GetWindowRect()检查这样的窗口是否实际上与您的窗口重叠.对于两个已知的窗口没有捷径，只需检查GetWindow()在迭代时是否返回hWnd2即可.

Iterate the windows that might overlap yours by repeatedly calling GetWindow(), using GW_HWNDPREV. Use GetWindowRect() to check if such a window actually overlap yours. There's no shortcut for two known windows, just check if GetWindow() returns hWnd2 while iterating.
