Servo WebView for Qt using CXX-Qt

KDAB has built a demo of using CXX-Qt to expose a Servo in Rust as a component to Qt.

Setup

• Ensure that you have Qt installed and qmake in your PATH.
• Ensure that you have the dependencies of ./mach boostrap from the https://github.com/servo/servo/ repository.
• Alternatively use the shell.nix by installing Nix and then running nix-shell, it will take care of all dependencies automatically
• Install the nightly compiler from February

$ rustup install nightly-2024-02-01
$ rustup default nightly-2024-02-01

• Then run in release mode

$ cargo run --release

Note that this demo currently supports Wayland only, not X11.

Debugging

To make sure, that Qt picks the correct OpenGL driver, use the QSG_INFO=1 variable. For hardware acceleration to work, the driver name should not contain llvmpipe. Note that on embedded hardware it might be necessary to force servo to use OpenGL ES.

Nix

If you using Nix and if not on NixOS, make sure to run the final executable with the nixGLMesa wrapper (or if not on Mesa, with the correct wrapper for your driver). This will make sure that the OpenGL drivers are passed through from the host system with nixGL.
