What are some ways to implement CSS styling in my GTK# program?

Is it possible to incorporate CSS styling in a GTK# application? Initially, I believed that using CSS themes in GTK# was not feasible until I stumbled upon this example which demonstrated the use of CSS styling in GTK#. Additionally, I came across samples from the Banshee project (utilizing GTK#) showcasing the utilization of CSS styling. However, despite my attempts, I could not locate the CssProvider class in GTK#. How can I access this class or implement CSS styling in GTK#?

CSS Styling is a unique feature of GTK3.

Although GTK# for GTK3 has not been officially released as stable yet.

Xamarin, the driving force behind mono, has publicly stated that their product (Xamarin Studio/Mono Develop) will not be transitioning to GTK3. This means that community support is essential for GTK3 adoption and progress has been slow.

If you are unable to locate the CssProvider class, it may be because you are using GTK2 bindings instead of GTK3 bindings.

If you want to experiment with the beta GTK3 CSharp bindings, they can be found here: https://github.com/mono/gtk-sharp/releases

Since Xamarin Studio does not support GTK3, I would suggest either:

  • Compiling GTK# yourself so that Xamarin Studio can still utilize the installed GTK2 bindings.
  • Using Visual Studio, which does not rely on GTK#.
