It's impossible for me to tell anything definite from this small code 
snippet.

Basically you use the custom widget functionality. Since I did not yet 
modify glade for use with glademm (on my TODO list), glademm derives the 
Type, Include File and Creation invocation from the "create" tag. You 
can insert a complex Expression and glademm will use the Function name 
(between ':' and '(') as a name for the include file (.hh added) and 
everithing up to a '(' as the type.
