On this section I will explain all the things that I had to do manually and took me some time to find out. Some of them are really simple but time-consuming so the idea is to reduce that time as much as we can.
== Migrate custom signals ==
If you have defined custom gtk objects with custom signal you should migrate them to [http://python-gtk-3-tutorial.readthedocs.org/en/latest/objects.html the new way] to do this.
You should replace this:
from gobject import signal_new, TYPE_INT, TYPE_STRING, TYPE_BOOLEAN, \
TYPE_PYOBJECT, TYPE_NONE, SIGNAL_RUN_LAST
signal_new('extlistview-modified', gtk.TreeView, SIGNAL_RUN_LAST, TYPE_NONE,
())
by adding the signal definition inside the object that you are creating using the <tt>__gsignals__</tt> dictionary like this (in this case Gtk.TreeView is the class that our object inherits):
from gi.repository import GObject
class ExtListViewColumn(Gtk.TreeViewColumn):
__gsignals__ = {
'extlistview-modified': (GObject.SignalFlags.RUN_LAST, None,
()),
}
The last argument of the signal definition are the argument types that the callback will receive. For example, that tuple could be (str, int) if the callback receives two arguments, a string and an integer (first and second argument position)
