Gtk3 Hackfest 2011

Two major changes have recently occurred in Sugar's underlying technologies. Firstly, GTK+ 2 has been obsoleted by GTK+ 3, and GNOME is now based on GTK+ 3. Secondly, PyGTK, the underlying Python library that Sugar uses to call into GTK+, has been deprecated in favour of PyGObject Introspection (hereafter "PyGI"). More background info can be found at Features/GTK3. Goal of this hackfest is to remove the biggest blockers before we can start the porting and potentially start porting over.

Agenda, goals

  • Removing Hippo and other custom widgets
    • Do we do this before or after GTK3? Note transparent window / icon overlapping issue.
  • migration path to Gtk3 (do we ship two toolkits? Do we migrate the shell and the toolkit and activities at once?)
  • porting Sugar's theme to gtk3 (go benzea, go!)
  • Port sugar-toolkit to GTK3 and release sugar-toolkit-0.95.x
  • Port Read to GTK3
  • Port Browse to Webkit/GTK3
  • other introspected libraries that need work (namely NM)
