Features/GTK3/Porting

To port PyGTK to PyGI, read this: https://live.gnome.org/PyGObject/IntrospectionPorting (especially the section abouut pygi-convert.sh)

If you are having trouble finding how a particular GTK class/method/constant has been named in PyGI, run pygi-enumerate.py and grep the output. (this app lists all identified methods and constants)

To document:

• Gtk.Alignment() no longer has default parameters - specify all 4

Conversion script badness:

-        if self.orientation == gtk.ORIENTATION_HORIZONTAL:
+        if self.orientation == Gtk.ORIENTATION_HORIZONTAL:

should be Orientation.HORIZONTAL

Tips to Activity Developers

this is just a stub

• GTK-3 does not support Drawable, so the first step is to get your activity running under Cairo.

• Example: abacus-cairo
• Example: abacus-gtk3

• The conversion script (here) leaves a few things to be done by hand:

• Notes from conversion from abacus-cairo to abacus-gtk3

• Notes from the TurtleArt conversion
• Removing Hippo
