[Glade-users] adding custom widgets written with Gtkmm

Im curious to see if it works, if it does, we can create a c++

If it doesnt work, you can use the "parent" argument to fake the type
in glade, and provide extra properties virtually by way of the catalog
(but introspecting the type in an automatic way would be nice).

I would be interested in this kind of stuff directly supported in
glade. I also use gtkmm
and I find really difficult to add widgets to glade (I gave up).

Indeed, it will need some changes to gtkmm as it will double initialise
(Gtkmm wraps the initialisation of gtk up with the initialisation of its
static data).

If the glade requires="" attribute supports keeping gtkmm initialised
for as long as there is at least one library that uses it then splitting
gtk and glib initialisation out from the gtkmm initialisation should
work - I think. But I haven't yet mapped everything in my head.

It looks like the below would work except as in the comment - any

  Glib::wrap_register_init(); // but without calling g_type_init()
