Old way:
- def expose_cb(self, area, event):
t = self.keymap.translate_keyboard_state(key['key-scan'], self.active_state, self.active_group)
New way:
success, keyval, effective_group, level, consumed_modifiers = self.keymap.translate_keyboard_state(key['key-scan'], self.active_state, self.active_group)
== 'expose-event' & 'draw' event ==
The new ''draw'' event that refers to the old ''expose-event'' into a Gtk.DrawingArea now receive the widget and the context instead the widget and the event:
''expose-event''
def expose_cb(self, area, event):
self.draw()
''draw'' event
def draw_cb(self, area, cr):
self.draw(cr)
