Re: gtk_builder_connect_signals

[Chris Scaife <scaife chris gmail com>]

Thanks for that confirmation Jason!
Indeed I found in <gtkmm/builder.h>

//TODO:_WRAP_METHOD(GSList* get_objects(), gtk_builder_get_objects)
//_WRAP_METHOD(void connect_signals(gpointer       user_data),
gtk_builder_connect_signals)
//_WRAP_METHOD(void connect_signals_full(GtkBuilderConnectFunc func,
gpointer       user_data), gtk_builder_connect_signals_full)

I suspect it has something to do with the difficulty of type safe
method invocation for a compiled language like C++ as opposed to ones
like Python that can manipulate their name space at run time. Now
knowing that function doesn't exist seems to be actually helping me to
fully embrace Object Oriented philosophy :)

I'm not sure whether it would be a good practice to continue
specifying signal handlers in the .glade file even though the binding
is being done independently in the code. Another problem is to
identify signals that glade knows about (e.g. window destroy) with an
appropriate widget signal that gtkmm handles.

p.s. I hope I'm doing the right thing responding to
gtkmm-list gnome org, I never used these mailing lists before.
