Hi,
While trying to run the itemview demos on an AMD64 computer I ran into a
problem: the
QModelIndex are built by passing the id() of a python object (which is a C long
integer) and
the Qt API requires an int. The value returned by index.internalId() is
truncated to an int,
and this value is used to make a lookup in a python dictionary which was built
using the
original 64bit value, and therefore we get a KeyError and the demo does not
work:
simpletreemodel$ python simpletreemodel.py
Traceback (most recent call last):
File "simpletreemodel.py", line 119, in parent
childItem = self.object_dict[index.internalId()]
KeyError: -414219776L
Traceback (most recent call last):
File "simpletreemodel.py", line 87, in data
item = self.object_dict[index.internalId()]
KeyError: -414219776L
<snip>
I tried to use index.internalPointer() which returns a reference on the python
instance being referenced by the model index. This works on i386, and segfaults
on AMD64. And
I am afraid that this can lead to strange things on i386 if the TreeItem is
garbage
collected.
I'm CC'ing this bug report the pykde mailing list, where people may have an
opinion on that
matter.
