[PyQt] Keeping references to parent objects

[Florian Bruhin]

Hi,

http://stackoverflow.com/a/11945184 says this:

    - A QObject should generally not have a reference to its parent or
      any of its ancestors (weak references are ok). This will cause
      memory leaks at best and occasional crashes as well.

      [...]

    - Objects that reference their parent or any ancestor can cause an
      exit crash.

Is this true? Is there more information about this somewhere?

I usually use signals, but there are some instances where it'd be
useful if an object kept a reference to its parent. Should I use
weakref for that everywhere?

Thanks,

Florian
