ok for the sake of this conversation: you are trying to integrate your custom
widget into glade, the fact that it is a composite widget is of little
consequence;
lets start by getting your instance running in glade and your
properties introspected.

Scratch my previous comment about a feature we never wrote, its
irrelevant here...

My fault I cleaned up my home dir... I posted on in its place just for you :)
(I'll attach it to this mail also...)

Only if you included the <glade-widget-group> portion of the catalog.

You should come join me in #glade3 on irc.gnome.org if you're having trouble
it'll be easier for me to help you there... before I misread you again...
what do you mean by "with signal handlers custom code hooked up" ?

Do you mean your vbox does things with signals ? or it just provides new
ones for the user ?
