Qt

For Qt-based applications we have the org.kde.Platform runtime (and corresponding org.kde.Sdk sdk runtime) that will offer us most Qt modules and KDE Frameworks for our applications to use.

For example, the following YAML makes building a random Qt application really straight-forward.

app-id: org.flatpak.qtdemo
runtime: org.kde.Platform
runtime-version: '5.11'
sdk: org.kde.Sdk
command: flatpak-demo
finish-args:
  - --share=ipc
  - --socket=x11
  - --socket=wayland
  - --filesystem=host
  - --device=dri
modules:
  - name: flatpak-demo
    buildsystem: cmake-ninja
    config-opts:
      - -DCMAKE_BUILD_TYPE=RelWithDebInfo
    sources:
      - type: archive
        url: https://github.com/flatpak/qt-flatpak-demo/archive/v1.1.2.tar.gz

The org.kde.Platform runtime includes all of Qt, including some KDE Frameworks. If you discover any issues we encourage you to report them. If you want more control, it’s also possible to use the org.freedesktop.Platform as a base and bundle the parts of Qt you need.
