Hi list,
I'm currently working on porting meld (the diff viewer) from pygtk to
gtkmm. It basically does the following when starting:
class MeldApp(Gtk.Application):
def some_method():
Gtk.Application.do_startup(self)
widget = builder.get_widget()
self.add_window(widget)
app.run(sys.argv)
I'm trying to do the same, but calling this->add_window() segfaults in
gtkapplicationimpl.c:88. I guess this is simply because I don't call
"do_start()" prior to this->add_window(). This is due to the reason it
only seems to exist in form of a signal in gtkmm. So my code basically
does:
class MeldApp : public Gtk::Application {
void some_method() {
#if 0
Gtk::Application::do_startup();
#endif
builder->get_widget("window", widget);
this->add_window(widget);
this->run(argc, argv);
}
}
Can anyone suggest on how to initialize a child class of
Gtk::Application (that was not instantiated using
Gtk::Application::create())?
In case anyone wants to take a look at the code:

I amend the last commit from time to time as way to much stuff is
still if'ed out :D
Thanks in advance,
Christoph
