= Focus =
== Focus ==
Implode defines a new widget called ''GridWidget'' and it should be focusable because we want to move a cursor with the key arrows on it. So, this widget was using:
self.set_flags(Gtk.CAN_FOCUS)
self.set_flags(Gtk.CAN_FOCUS)
by
but that method (''set_flags'') is no longer available and we have to replace it by:
self.set_can_focus(True)
self.set_can_focus(True)
Another thing related with the focus is to know who has the actual focus. In gtk2 it was done by
.focus_child
and in Gtk3 it should be replaced by:
.get_focus_child()
= Handling .svg with rsvg =
'''rsvg''' is a library to manage ''.svg'' files. The only thing that I found that should be updated is the import and the loading of a rsvg from data.
Replace the usual import:
import rsgv
import rsgv
by the Gtk3 one:
from gi.repository import Rsvg
from gi.repository import Rsvg
This way to load a rsvg from data should be replaced:
rsvg.Handle(data=data)
rsvg.Handle(data=data)
by this new way
Rsvg.Handle.new_from_data(data)
Rsvg.Handle.new_from_data(data)
