GtkD is a D binding and OO wrapper of Gtk+ and is released on the LGPL
Close to the 3.4 release, but the new functionality to now also remove
registered signal handlers added by Gerald Nunn warrants a new release.
Signal handles can be removed with the
gulong id = addOnDraw(&myHandler);
Users who previously removed there handlers from the internal array used
by GtkD will need to update there code to the new system.
