Hi Gabriel, thanks for your answer. This clarifies the second point in the documentation "Creates a local representation of a window created by another process or by using native libraries below Qt.". But am I right with my assumption, that the first statement "... created by another process ... " is not supported on OS X? I cannot imagine a way to get a valid NSView* from a different process. You can share NSWindows across applications (see toward the end of https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/WinPanel/Tasks/SettingWindowImageAttr.html and -[NSApplication windowWithWindowNumber:]). I have never tried anything of that sort, and I don’t even know what kind of information you can access. Even if it’s possible to access the NSWindow content view, it remains to be seen whether you can move/reparent NSViews across applications. Probably other platforms allow this, hence the doc.

This is what QCocoaWindow::winId() returns when called by QWindow::winId(). That means that, on Mac, we use NSView as the native window class, including for top-level windows.
