Contributing

Come join us and work with us on one of the world's most popular toolkits!
We can not directly offer big money, but you get to work on a stable, proven, extensible toolkit,
share experience, code and ideas with hundreds of people minded just like you: loving the free
and open atmosphere, and free, open code!

We are always, but currently very keenly looking for new developers with preferrably present
experience with Gtk+, or another toolkit, firm knowledge of C and a UNIX environment
(development with Gtk+ is possible under Windows, too!), and first and foremost: fresh ideas.

If you think you can contribute to Gtk+, or already have contributed to Gtk+ with a third-party
library and would like to join main development, you can take a look at one of the pages below, or
contact us directly on the Gtk+ Development Mailing List.

Also, don't forget to take a look to our commit policy

Don't hesitate - join now: we are happy to hear from you!

• Checklist of things to do when writing a widget

  • Chain up to the correct parent handlers for GtkWidget methods (which ones?)

  • Handle GtkWidget::style_set.

  • Handle GtkWidget::screen_changed.

  • Handle GtkWidget::focus if you have focusable sub-parts.

  • Make widgets usable with the keyboard.
  • Add accessibility support (out of the scope of this document).

  • Use GtkBindingSet

  • When displaying an animation, or doing a button-repeat timeout like e.g. GtkSpinButton, make sure you stop it when necessary: when getting grab-shadowed, when becoming insensitive, when unmapped.

  • When working with pointer or keyboard grabs, handle the grab-broken events. This is also true for implicit pointer grabs established by button presses: if you need to do any cleanup in your button-released handler, do the same cleanups in the grab_broken handler.
