Real hwnd from the point

When we use WindowFromPoint winapi function we usually can get the case, when Point specifies to some control within a window. And in such cases WindowFromPoint returns handle to that control, not to the window that handles that control.

For example in my small test application if I point to the "body" of chrome browser I get the control with class = Chrome_RenderWidgetHostHWND and its hwnd.

But what I need is to get the "parent" window for tha开发者_Go百科t control (which is obviously should be the chrome window).

Traverse the parents using GetAncestor() passing GA_PARENT. This differs from calling GetParent() which will return the owner if the window is a top-level window.

Can't you just use GetParent? Keep traversing until you find the desktop window.
