sqlite is not ruby, so you should look for a sqlite group ;)

Do you mean that after replacing TreeWidgetItem with QTreeWidgetItem your 
nitem_clicked slot still doesn't get called? If so, that's weird, since I 
tried it and it works for me.

It may be a bug in qtruby, but I'm not sure. You can ask on the QtRuby mailing 
list (subscribing at https://mail.kde.org/mailman/listinfo/kde-bindings). If 
you don't, I'll do that one of the next days, as soon as I have a bit of free 
time. However, I've noticed that if I define a new signal in the custom class, 
metaObject#signalNames returns it, but it still doesn't contain signals from 
the base class.
