Hi,
I'm trying to implement an ATK object for a custom GTK widget, however
my ATK object factory class doesn't seem to actually get used. I've
boiled down what I'm doing to the following test code:
#!/usr/bin/env python
import atk, gtk
class CustomWidget(gtk.DrawingArea):
def __init__(self):
gtk.DrawingArea.__init__(self)
print self.get_accessible()
class CustomWidgetATK(atk.GObjectAccessible, atk.Component):
def __init__(self, obj):
atk.GObjectAccessible.__init__(self)
print "Custom ATK for", obj
class CustomWidgetATKFactory(atk.ObjectFactory):
def __init__(self):
atk.ObjectFactory.__init__(self)
print "Factory initialised"
def create_accessible(self, obj):
print "Created accessible"
return CustomWidgetATK(obj)
atk.get_default_registry().set_factory_type(CustomWidget,
CustomWidgetATKFactory)
if __name__ == "__main__":
c = CustomWidget()
The self.get_accessible() call just returns None (and if the
CustomWidgetATKFactory isn't added to the ATK registry then it returns
the normal DrawingArea accessible object). Neither the create_accessible
method nor constructor for CustomWidgetATKFactory ever get called.
Any advice on where I'm going wrong would be greatly appreciated.
Thanks,
Mike.
