* http://www.pygtk.org/docs/pygtk/class-gdkkeymap.html#method-gdkkeymap--translate-keyboard-state

~~----~~

Old way:

- def expose_cb(self, area, event):

t = self.keymap.translate_keyboard_state(key['key-scan'], self.active_state, self.active_group)

- self.draw()

+ def draw_cb(self, area, cr):

New way:

+ self.draw(cr)

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)
