English: If I understand correctly, typing F2 is used to hide contact list. But typing F2 causes empty screen, except for menus. If you type F2 again, it causes a traceback (see below) Français: Si j'ai bien compris, appuyer sur F2 permet de cacher la liste de contact. Mais lorsque l'on appuie sur F2, l'écran se vide à l'exception des menus en haut. Si on appuie encore sur F2, un traceback apparaît (voir plus bas) Traceback: Xlib.protocol.request.QueryExtension Traceback (most recent call last): File "/usr/local/bin/primitivus", line 556, in <module> sat.start() File "/usr/local/bin/primitivus", line 112, in start self.loop.run() File "/usr/local/lib/python2.7/dist-packages/urwid/main_loop.py", line 272, in run self.screen.run_wrapper(self._run) File "/usr/local/lib/python2.7/dist-packages/urwid/raw_display.py", line 242, in run_wrapper return fn() File "/usr/local/lib/python2.7/dist-packages/urwid/main_loop.py", line 337, in _run self.event_loop.run() File "/usr/local/lib/python2.7/dist-packages/urwid/main_loop.py", line 1014, in wrapper return f(args,*kargs) File "/usr/local/lib/python2.7/dist-packages/urwid/main_loop.py", line 881, in io_callback callback() File "/usr/local/lib/python2.7/dist-packages/urwid/main_loop.py", line 388, in _update self.process_input(keys) File "/usr/local/lib/python2.7/dist-packages/urwid/main_loop.py", line 494, in process_input something_handled |= bool(self.unhandled_input(k)) File "/usr/local/lib/python2.7/dist-packages/urwid/main_loop.py", line 540, in unhandled_input return self._unhandled_input(input) File "/usr/local/bin/primitivus", line 159, in keyHandler center_widgets.insert(0, self.contact_list) File "/usr/local/lib/python2.7/dist-packages/urwid/monitored_list.py", line 28, in call_modified_wrapper self._modified() File "/usr/local/lib/python2.7/dist-packages/urwid/container.py", line 1762, in user_modified self._set_widget_list(ml) File "/usr/local/lib/python2.7/dist-packages/urwid/container.py", line 1766, in _set_widget_list focus_position = self.focus_position File "/usr/local/lib/python2.7/dist-packages/urwid/container.py", line 1935, in _get_focus_position raise IndexError, "No focus_position, Columns is empty" IndexError: No focus_position, Columns is empty
