[Glade-users] Passing objects to libglade callbacks

[Günther Mittermayer]

Russell, 

I'm not sure on what you want to do, but I think you might be using the Object field in a wrong manner... I might be just guessing, since I actually never used it, but I think it is used to determine the object which should receive the specified signal, and therefore, "1" doesn't make any sense to me.....

I would try finding out what it really means.. and again, I'm just guessing..

Günther.
