           Summary: Optionally disable on_*() default signal handlers.

There is a huge code size gain to be made by removing default signal hand=
lers,
such as Gtk::Button::on_clicked(). The problem is that they are virtual
methods, so we have to pay for them even if we don't use them. We must pa=

them in=20
- code size: That's a lot of symbols in libgtkmm, and the symbols must be
listed in applications that use libgtkmm.
- load time: the symbols must be resolved by applications that use libgtk=
mm.

Gtk::Widget has about 60 signals, so that's at least 60 virtual methods f=
or
each widget. As far as I can tell, this increases the code size of each d=
erived
class, even if a derived-of-derived class, maybe due to multiple inherita=
nce.

I have not yet committed this configure option to cvs, because this is th=
e most
disruptive option. Overriding virtual methods, instead of connecting sign=
als,
is quite convenient, but I don't think it's worth the cost on an embedded=
 plat

By the way, this reduces the libgtkmm .so code size by about 500K.

One of the disadvantages of applying this would be that we'd need some ra=
ther
more intrusive #ifdefing in some examples than we need for the other
--enable-api-* optoins. That would make them confusing for beginners.

           Product: gtkmm
           Version: 2.9.x

   GNOME milestone: Unspecified


Neither version 2.8.6 nor 2.9.1 compile.  The problem is with
gtk/gtkmm/uimanager.c:

uimanager.cc: In member function 'guint
Gtk::UIManager::add_ui_from_string(const Glib::ustring&)':
uimanager.cc:45: error: 'error' was not declared in this scope
make[6]: *** [uimanager.lo] Error 1


A quick look at the the code reveals a declaration for gerror, but not er=
ror.
