Hello,
I'm fairly new to developing inside gtkmm. I'm trying to wrap
GtkPlacesSidebar. I managed to get a first version
(https://bugzilla.gnome.org/show_bug.cgi?id=705642) and now I'm
writing a simple example to test it.
In that example program I attach a handler to the open-location
signal. That signal, when emitted, provides a Gio::File object in the
form of Glib::Object; when it is emitted I get this message:
glibmm-WARNING **: Failed to wrap object of type 'GLocalFile'. Hint:
this error is commonly caused by failing to call a library init()
function.
GtkPlacesSidebar docs state that the signature for that signal handler
should be:
void user_function (GtkPlacesSidebar *sidebar,
GObject *location,
...)
where location is a GFile.
I've added Gio::init() at the beginning of my main.cc, but the problem
remains. I would like to learn how this can be done, and why it is not
working.
Thank you very much in advance.
Regards,
Juan.
gtk_init() must be called in a gtk+ program, and thus also in a gtkmm
program. gtk_init() is called by
Gtk::Application::create(int& argc, char**& argv, const
Glib::ustring& application_id, Gio::ApplicationFlags flags)
but it's not called by
Gtk::Application::create(const Glib::ustring& application_id,
Gio::ApplicationFlags flags)
Don't know if this is bug, or done deliberately. My guess is that both
Gtk::Application::create() shall call gtk_init().
Don't know if a missing call to gtk_init() is the reason for your
warning message.
