[Glade-devel] New UI for the signal editor

[e98cuenc free fr (Joaquin Cuenca Abela)]

Hi!

I've committed a new UI for the signal editor.

You can have several handlers for the same signal with this UI, and it's IMO
easier to use than the old interface.

I've not yet fixed the problem about quickly discover the whole set of
signals already that have a handler connected to, as right now it only opens
the first widget class.

Comments appreciated.

Cheers,
