gramps/gramps2/src/PedView.py
Alex Roitman 358f95a2be * src/PedView.py (PedigreeView.__init__): Add parent argument to the 
constructor. Connect to the handling function on button press over the
canvas to enable context menu;
(on_canvas_press, build_nav_menu): Add functions to enable context menu.
* src/gramps_main.py (init_interface): Call PedView with self as parent.
* src/PlaceView.py (merge): Change error message from people to places.
