And gtk_main_* is not Gtk::Main. Gtk::Main is a C++ class inside a C++ 
namespace.

The issue is not in libpanel-applet, but in libpanelappletmm. 
libpanelappletmm relies on gtkmm, which wraps GTK+. In a gtkmm based 
program, you don't deal with GTK+ directly (that's why we call it a 
wrapper).

GTK+'s initialisation is done by the Gtk::Main class. That's how gtkmm 
works, and so that's what libpanelappletmm should use.


I hope you understand. If you don't, take a look at gtkmm's tutorial 
(even just this page :

)
