The gtkmm tutorial shows two ways of handling command line arguments, 
but it's described in a place where you probably don't think of 
searching for it (I'm to blame for that):
https://developer.gnome.org/gtkmm-tutorial/stable/sec-multi-item-containers.html.en#boxes-command-line-options
 Look also at main.cc in the example after the description.

Gtk::Application ought to have a chapter of its own in the tutorial, but 
so far no one has taken the time to write that chapter. Much more than 
handling command line arguments ought to be described in such a chapter.

      Hi, I am trying to parse some command line arguments within my
      program. This is what I have:<br>
      <br>
      Glib::RefPtr&lt;Gtk::Application&gt; app =
      Gtk::Application::create(argc, argv, "Math.Calculator.Fractions");<br>
      <br>
      &nbsp;&nbsp;&nbsp; Math::Gui::MainWindow mw(argc, argv);<br>
      &nbsp;&nbsp;&nbsp; <br>
      &nbsp;&nbsp;&nbsp; return app-&gt;run(mw);<br>
      <br>
      when I run the program I get the error message:<br>
      <br>
      "GLib-GIO-CRITICAL **: This application can not open files."<br>
      <br>
      The only information I can find about command line arguments is
      using Gio::APPLICATION_HANDLES_COMMAND_LINE flag and <font
        color="#000000">connect to
        Gio::Application::signal_command_line().<br>
        <br>
        Is there a simpler way?<br>
        <br>
        Thank you.<br>
