Re: [gtkmm] glademm get_widget_derived

[Christer Palm <palm nogui se>]

OK - I'll check it out... (in more than one sense :-))

I didn't quite get what you mean though - do you mean that the with the 
CVS version, you don't have to create a new Gnome::Glade::Xml for each 
instance anymore? Or is it the other way around?

Anyhow, this brings up a question I asked before, but never got answered;

If I call Gnome::Glade::Xml::create() more than once on the same file, 
will the XML file be parsed all over again? If so I guess it makes sense 
to split up the interface into separate files for each Window/Dialog to 
speed up the parsing and reduce the overhead of keeping several copies 
of the whole interface in memory? Or does libglademm do this for you 
under the cover?
