I need to include QtPlatformHeaders/QWindowsWindowFunctions

Arist0tle

Hi,

I'm using Qt 6.0.2 in connection with Visual Studio 2019 and I don't know how to include QWindowsWindowFunctions (I need this to solve a OpenGL issue, see https://doc.qt.io/qt-6/windows-issues.html).
I tried #include <QtPlatformHeaders/QWindowsWindowFunctions> but it didn't work.
I couldn't even find a directory QtPlatformHeaders somewhere in the Qt folder...

Do I need to install something else?

Thanks for any help!

Looks like it's not yet ported - stay at 5.15 until then.

Hi and welcome to devnet,

It might also have been moved, see this blog post.

Thank you very much for your answers so far!
Yes, it seems that QWindowsWindowFunctions::setHasBorderInFullScreen has been moved to QWindowsWindow.
I've been trying to get

using namespace QNativeInterface::Private;
if (auto *windowsWindow = dynamic_cast<QWindowsWindow*>(window->handle()))
    windowsWindow->setHasBorderInFullScreen(true);
[...]

to work (from the blog) but I don't know exactly how:

The class QWindowsWindow is defined in QtGui/6.0.2/QtGui/qpa/qplatformwindow_p.h. It seems a bit strange to include this file?
Do you know how I can get window->handle() from QMainWindow?

Many thank again :)

For my actual problem (QMenu not visible when using OpenGL in QMainWindow with full screen) I found workarounds described in https://bugreports.qt.io/browse/QTBUG-41309.

So I think I can close this thread, because as @Christian-Ehrlicher wrote, QWindowsWindowFunctions doesn`t seem to be ported properly yet.

@SGaist Thank You. This helps and this is what I was searching for.
