How to build (containerize a Qt6 app)

docker build . -t qt-hello:0.0.4

How to run

docker run --rm -e WAYLAND_DISPLAY=$WAYLAND_DISPLAY -e XDG_RUNTIME_DIR=/tmp -v $XDG_RUNTIME_DIR/$WAYLAND_DISPLAY:/tmp/$WAYLAND_DISPLAY localhost/qt-hello:0.0.4

If you need to enter the container to view the environments and experiment with it:

docker run -it --entrypoint /bin/bash
   -e WAYLAND_DISPLAY=$WAYLAND_DISPLAY \
   -e XDG_RUNTIME_DIR=/tmp \
   -v $XDG_RUNTIME_DIR/$WAYLAND_DISPLAY:/tmp/$WAYLAND_DISPLAY \
   localhost/qt-hello:0.0.4

Issues

1. Cannot open a model dialog

Wayland does not support QWindow::requestActivate()
