Bug or feature? I don't really know. Anyway I had to make some changes
in Gtk::Application, because applications that used
Gtk::ApplicationWindow instead of Gtk::Window crashed. See
https://bugzilla.gnome.org/show_bug.cgi?id=681323#c1.
The new version 3.5.13 is more like the example programs shipped with
gtk+, so I suppose it's more like the developers of glib and gtk+ think
it shall be done.
The problem for you is that if you add
Gio::APPLICATION_HANDLES_COMMAND_LINE, the default implementation of
virtual function local_command_line() does not emit the /activate/
signal, which is now necessary, or else the window will not be added to
the application and shown. If you use
Gio::APPLICATION_HANDLES_COMMAND_LINE you must either override
Gio::Application:local_command_line_vfunc() in a subclass, or (easier)
connect to Gio::Application::signal_command_line(). In your signal
handler, handle the command line arguments and then call
Gio::Application::activate().
There is a long description of Gio::Application:run() at
http://developer.gnome.org/glibmm/unstable/classGio_1_1Application.html.
Read carefully and slowly, it's not easy to understand all the details.

Hi,
If I add the param "Gio::APPLICATION_HANDLES_COMMAND_LINE" to Gtk::Application
it exits automatically.
Is it a bug or feature?
Simple sample:
#include <gtkmm.h>
int
main(int argc, char *argv[]) {
Glib::RefPtr<Gtk::Application> app = Gtk::Application::create(argc,
argv,
"org.app.com");//, Gio::APPLICATION_HANDLES_COMMAND_LINE);
Gtk::Window win;
win.show_all();
app->run(win);
return 0;
}
It compiles and runs fine, however if you add/uncomment the
Gio::APPLICATION_HANDLES_COMMAND_LINE param
to the app it will compile fine but the executable execute past app->run(win)
and just exit.
It happens on Ubuntu 12.10 amd64 which ships with libgtkmm-3.0-dev version
3.5.13-0ubuntu1
On Ubuntu 12.04 I don't have this subtle issue, however it complains if I don't
add this param yet access the param list later on.
