[Glade-users] glade-3 and user data

[Keith Eberle]

Hmm...
When I run this ($ pyton ./myglade) it prints:
./myglade:15: GtkWarning: Could not lookup object somedata on signal clicked
of object button
  builder.connect_signals(self)

"somedata" is the data I entered in the User Data field in Glade.

Anyway, I printed the values of all parameters the signal handler received:

    def on_button_clicked(self, widget, data=None):
        print self
        print widget
        print data

And I see:
<__main__.MyClass object at 0xb7d9aaec>
<gtk.Button object at 0x9abf6bc (GtkButton at 0x9b6d820)>
None

I was expecting to see that "print self" printed "somedata"...

(First time using these mailing lists too... very confusing, so I hope this
reply works)

GtkBuilder did not change in that respect, what we need is to
add api to builder signal parsing so that the swapped flag to
signal connect can be optional (this will be less confusing of course).
