如何在所需的应用程序上检查鼠标单击位置？

Question

I know the mouse click position using API GetCursorPos and the handle of application ( HWND ).

How can I check mouse click position is on this application?

My view:

• Get the bounding box of application from its handle. ( GetWindowRect(hWnd, &rect); )
• Check cursor position lies in this bounding box. ( PtInRect(&rect, p) )

This is not working if windows are overlapping.

Answer 1

As we know the handle of targeted screen handle and click cursor position:

// hWnd : Already known windows handle

GetCursorPos(&p);
HWND hWndFromPoint = WindowFromPoint(p);

// If the handle got from click point is child of the desire window means it is clicked on the desire window itself.
if (IsChild(hWnd, hWndFromPoint))
{
    // Do something on Mouse click 
}
