Menus and connect_to_method in Gtk--

[Derek Wyatt <derek scar utoronto ca>]

Howdie.

My connect to methods don't seem to be working and i can't figure out why.
The actual menu works great.  It displays wonderfully and is well behaved.

But...

I keep getting the same compilation error about the signal template... i'm
hoping someone can take a few minutes and help me out here. 

Here's the error i get:

g++ -c -Wall menu.cc
menu.cc: In method `FileMenu::FileMenu()':
menu.cc:33: no matching function for call to `connect_to_method
(Signal_proxy0<void,Gtk_MenuItem> &, FileMenu *, int (FileMenu::*)())'
make: *** [menu.o] Error 1

Here's the code (I'm removing the irrelevent stuff):

-------------------- start window code -------------------------

class MasterWin : public Gtk_Window
{
   MasterMenu menu;

public:
   MasterWin();
   MasterWin(gint x, gint y, gchar const *title);
   gint delete_event_impl(GdkEventAny *);
   void add(Gtk_Widget *w) { vbox.pack_start(w,FALSE,FALSE,0); }
};

MasterWin::MasterWin(gint x, gint y, gchar const *title)
{
   add(&menu);   // internal method to this class
   menu.show();
}

----------------- end window code ------------------------------

----------------- start menu code ------------------------------


class FileMenu : public Gtk_Menu
{
   Gtk_MenuItem *newFile, *open, *save, *saveAs, *quit;

public:
   int quit_program(void);
   FileMenu();
};

class MasterMenu : public Gtk_MenuBar
{
   Gtk_MenuItem fileSub;
   FileMenu fileMenu;

public:
   MasterMenu();
};

MasterMenu::MasterMenu() : fileSub("File")
{
   fileSub.show();
   fileSub.set_submenu(&fileMenu);
   append(&fileSub);
}

FileMenu::FileMenu()
{
   append(newFile = new Gtk_MenuItem("New"));
   append(open = new Gtk_MenuItem("Open"));
   append(save = new Gtk_MenuItem("Save"));
   append(saveAs = new Gtk_MenuItem("Save As"));
   append(quit = new Gtk_MenuItem("Quit"));
   newFile->show();
   saveAs->show();
   save->show();
   open->show();
   newFile->show();
   quit->show();
   connect_to_method(newFile->activate, this, &quit_program);
}

------------------------ end menu code -------------------------


THANKS!!!
