implying that the assignment operator '=' will call the copy constructor
in this line "Gtk::EventBox gtkmmApplet = static_cast<Gtk::EventBox>
(*applet)" with that in mind I changed that line to:
Gtk::EventBox &gtkmmApplet = static_cast <Gtk::EventBox> (*applet);

However, that gives me the same error as above, specifically:
error: no matching function for call to 'Gtk::EventBox::EventBox
(_PanelApplet&)'

I attached the full source, too.
