I'm trying to subclass GnomeCanvas and defined my own signal, but for
some my new signal is unrecognised. This is (a reduced version of) my
code:
import pygtk
pygtk.require('2.0')
import gobject, gnome, gnome.canvas, gtk
class SystemCanvas(gnome.canvas.Canvas):
__gsignals__ = {
'changed2' : (gobject.SIGNAL_RUN_LAST, gobject.TYPE_NONE,
(gobject.TYPE_STRING,)),
}
def __init__(self, aa=gtk.TRUE):
gnome.canvas.Canvas.__init__(self, aa=aa)
self.res = 1
print gobject.signal_list_names(SystemCanvas)
self.connect('changed2', self.void)
return
def void(self, canvas, arg1, data=None):
return gtk.FALSE
gobject.type_register(SystemCanvas)
if __name__ == "__main__":
s = SystemCanvas()
The error I get is:
[EMAIL PROTECTED] src]$ python SystemCanvas2.py
('changed2',)
Traceback (most recent call last):
File "SystemCanvas2.py", line 22, in ?
s = SystemCanvas()
File "SystemCanvas2.py", line 14, in __init__
self.connect('changed2', self.void)
TypeError: unknown signal name
[EMAIL PROTECTED] src]$
The signal is obviously registered, but for some reason I can neither
connect to nor emit it. Any ideas?
