= 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) | ||
