Description:
GTK+ bindings: Glade support
Contains bindings for the glade library from use within Python. Glade makes it very easy to create a user interface. In the target application you just need to load the interface description from the .glade file instead of constructing the GUI at runtime. . This package is deprecated, you should migrate to using gobject-introspection (GIR) based python bindings instead (PyGObject). https://wiki.gnome.org/Projects/PyGObject/IntrospectionPorting
