Re: App menu name

We've identified the problem and the solution. The issue seems to be confined to one flavor of desktop in one flavor of Linux. Search engines will eventually pick this up, so I'm inclined to let it go.

You're right. If I add a .desktop file for the application, and run the Ubuntu Unity desktop environment, the name of the app menu is read from the Name entry in the .desktop file. But the Gnome Flashback desktop environment lets gtk+ display both the app menu and the window's menubar attached to the window. And gtk+ still gets the app menu name with g_get_application_name(), if Glib::set_application_name() has been called. If not, Gnome Flashback also gets the app menu name from the .desktop file.

To further complicate the issue, Unity and Gnome Flashback/gtk+/glib seems to use slightly different algorithms for finding the right .desktop file, when the program has been started from the command line. I haven't investigated in detail, and I don't want to do it. Basically it seems Gnome Flashback only considers .desktop files with the same name as the executable file, while Unity checks the contents of the .desktop files (the Exec and/or the TryExec entries, I think).

If you think the issue with the app menu name needs further investigation or documentation, please file a bug in Bugzilla, preferably with suggestions what to do.

I am now seeing my application's name as the app menu title, and it appeared after I created a .desktop file for the application. When I remove the ,desktop file, the app menu title reverts to "Unknown Application Name."

I suppose you have seen the example at Unfortunately it's not mentioned in the gtkmm tutorial. The tutorial would benefit from a whole new chapter, describing Gtk::Application and Gtk::ApplicationWindow. More volunteers would be welcome. The gtkmm tutorial has not been kept up-to-date with the latest changes in gtk+ and gtkmm. As an example, the Gesture classes are not mentioned.

There is a short description of command-line options in the section that describes Boxes,

I'm also running Ubuntu (14.10), and I use the Unity desktop. I'm inclined to regard Unity as the prime suspect, so I'll submit a bug report accordingly.

I was also looking at the changes you mention, and I think it would be great if you could demo the handling of command-line option and file parameters as well...

At runtime the app menu is titled "Unknown Application Name," but the win menus are properly titled as "File," "Edit," and "Notification."

Does this imply that something is missing from the code?
I have recently pushed some changes that make the menus/main_menu example use an application menu. Then I noticed the same thing.

I use Ubuntu, which has two desktop environments to choose from: Ubuntu Unity and Gnome Flashback. Ubuntu Unity shows both the app menu and the menubar outside the application's window, and the app menu is titled "Unknown Application Name". Gnome Flashback shows both the app menu and the menubar in the application's window, and the app menu is titled "Gtk::Application Example" (or whatever name is set with Glib::set_application_name()). Gtk+'s demo program behaves the same.

I don't know if something is missing in these programs, or if it's a bug in the Ubuntu Unity desktop shell. Which operating system do you use?
