[PyKDE] Null pointer test

[Ingo Krabbe]

Hi,

I've the following problem, while trying to build a tree in a QListView:

Each Item of the QListView is a QListViewItem.  I insert into the tree
in sorted manner by storing the last parent and starting with the
QListView as the initial parent:

	item = QListViewItem( parent, X_i )
	parent.insertItem( item )
	parent = item

When I want to go a level up I do:

	parent = parent.parent()

But this only works if we aren't at the root node since a QListViewItem
isn't a QObject but opens an own base class.  So

	parent.parent() would give NULL in C++.

What's returned in pyqt here ?

TIA INGO
