◆ findPlatformWindowHelper()

bool findPlatformWindowHelper ( const POINT & screenPoint,
unsigned cwexFlags,
const QWindowsContext * context,
HWND * hwnd,
QWindowsWindow ** result )
inlinestatic

Find a child window at a screen point.

Deep search for a QWindow at global point, skipping non-owned windows (accessibility?). Implemented using ChildWindowFromPointEx() instead of (historically used) WindowFromPoint() to get a well-defined behaviour for hidden/transparent windows.

cwex_flags are flags of ChildWindowFromPointEx(). parent is the parent window, pass GetDesktopWindow() for top levels.
