Build Status

GTK4 Crystal Bindings

See examples folder and have fun.

If you feel this repository too silent is because most of the development happens in the binding generator repository, not here.

API docs

Current documentation is far from being good, but is better (not much) than nothing.

API docs can be found at

To generate the documentation clone this repository then do:

$ make doc

The documentation will be found at docs/index.html.

Compile time dependencies

You need the GTK libraries and their GObjectIntrospection files.

  • Archlinux: pacman -S gtk4 gobject-introspection
  • Ubuntu: apt-get install libgtk-4-1 libgtk-4-dev libgirepository1.0-dev gobject-introspection gir1.2-gtk-4.0
  • macOS: brew install gobject-introspection gtk4

Be welcome to create a PR updating this readme once you know what packages are needed by your distro to run the examples.

Runtime dependencies

Just the GTK libraries are needed at runtime, i.e. not the gobject-introspection library and files.


  1. Add the dependency to your shard.yml:

        github: hugopl/
  2. Run shards install


See the hello world tutorial.

For more info on how to use signals, properties, etc see the GI-Crystal project page, it's the binding generator used to create this binding.
