[pygtk] How can I inherit __gsignals__ attribute from a class?

2009-06-01 Thread Iven Day 
Hi,
I wrote a parent class like this:

class PluginObject(gobject.GObject):
__gsignals__ = {
"change-ui": (gobject.SIGNAL_RUN_FIRST,
  gobject.TYPE_NONE,
 (gobject.TYPE_PYOBJECT, gobject.TYPE_STRING,)),
   }
def __init__(self):
gobject.GObject.__init__(self)

, and a child class like this:

class PluginComboBox(gtk.ComboBox, PluginObject):
def __init__(self, input_dict):
PluginObject.__init__(self)
gtk.ComboBox.__init__(self)
...
self.connect("changed", self.changed_cb, input_dict)
self.set_active(0)
def changed_cb(self, widget, data = None):
model = self.get_model()
index = self.get_active()
self.emit("change-ui", data.values, data[model[index][0]])

, but I got a

TypeError: : unknown signal name: change-ui

It seems __gsignals__ isn't inherited, how can I get it work?
Sorry for my english.

It seems __gsignals__ only works as user-defined signals in pygtk when
it is defined as a class attribute, isn't it?

I just tried, but it doesn't work. I think __gsignals__ must be a class
attribute so that signals within it could be emited, but not data
attribute(self.xxx).
