test pyqt6 client

[totaam]

Just for testing, because it's actually fairly easy to implement now that the code is quite modular.

[totaam]

The commit above implements a tiny and not very useful client that is only capable of showing windows using rgb encoding..
It only supports tcp, no authentication, no keyboard, no nothing.

python3 xpra/client/qt6/main.py 127.0.0.1 10000

[totaam]

Now available as a package: xpra-client-qt6 and also included in the win32 fat builds.
Can be tested using:

XPRA_GUI_BACKEND=qt xpra attach tcp://192.168.0.10:10000/

Still only works for TCP sockets.

Some useful documentation links:

• QWindow class
• Qt6 window geometry
• Qt6 event system
• PyQt6 events and signals

[totaam]

Important: new syntax for enabling the qt6 client:

xpra attach tcp://192.168.0.10:10000/ --backend=qt

@totaam could you update debian packaging, because I would like to use it, but now it is unavailable.

[totaam]

@hadogenes the packaging bits are in 0c0291c.
There is a long queue of stable / lts builds ahead of this.
In the meantime, you can easily build it: https://github.com/Xpra-org/xpra/blob/master/docs/Build/Debian.md

Be aware that this is not a complete client by any means.
