Re: libglademm: mixing Gtk-C code with gtkmm-C++ code possible?

[Roger Ferrer Ibáñez <rofi ya com>]

Hi,

I've done a plugin for nautilus using gtkmm and it was necessary to do

Gtk::Main::init_gtkmm_internals();

before doing anything with gtkmmm. Don't know if this is the correct way
but it works. Failing to do that caused lots of stranges messages from
gtkmm, crashes, and of course no widget appeared.

Cheers,
