Re: [gtkmm] Glade-2, libgtkmm, Xml::create, callbacks

[Douglas Roberts <dzzr lanl gov>]

Hi, Christer.

Actually, all the information to connect the signals is available at 
compile time:  glade writes out the callback stubs as C++ code.

I'm beginning to suspect that using XML::create() might be a mistake in 
my case.  What I want out of gtk+/glade is a RAD, where all aspects of 
the gui are defined by the RAD (glade-2), and no manual code hacking is 
required to redefine things like callbacks that were already defined by 
the RAD (but ignored by XML::create()).

All I really need is a handle to the Gtk C++ object wrappers to those 
gtk widgets defined via glade, like what is provided for by 
lookup_widget when C bindings are used to save the glade-produced 
interface.  There _must_ be a lookup tool provided for this when glade 
saves the GUI with C++ bindings.  Does anybody know what the functional 
equivalent of lookup_widget is for C++ glade-produced code?

Thanks,

--Doug
