[PyKDE] Python references and the GC

[Kaleb Pederson]

I have a class similar to the below that keeps a reference to itself so that 
it doesn't get garbage collected.

class sample(qdialog):
	def __init__(...):
		qwidget.__init__(...)
		self._keep = self
		...

	def closeEvent(self,event):
		self._keep = None
		...
class ...(QWidget):
    def myfunc(self):
        inst = sample(0,name,FALSE) # created so its modeless with no parent
        self.connect(self,PYSIGNAL("closing()"),inst.closeMe)
        return

When should I delete the reference to the object? When WDestructive close is 
passed as a parameter I get the following:

Traceback (most recent call last):
  File "/home/kibab/.../src/gui/MainInterfaceImpl.py", line 1346, in 
closeEvent
    self.emit(PYSIGNAL("closeChild()"),() )
RuntimeError: Underlying C/C++ object has been deleted

However, the documentation says:
"Note that when a slot is a Python callable object it's reference count is not 
increased. This means that a class instance can be deleted without having to 
explicitly disconnect any signals connected to its methods." 
(http://www.riverbankcomputing.co.uk/pyqt/docs/x225.html).

Disconnecting doesn't work, however, per my last post.

What do other people do when they want to have a modeless non-parented dialog?

Thanks.
