[PySide] How do you check if an object is still alive in PySide?

[Mark Summerfield]

Hi,

In PyQt you can write an isAlive() function like this:


    def isAlive(qobj):
        import sip
        try:
            sip.unwrapinstance(qobj)
        except RuntimeError:
            return False
        return True

You can then ask about a top-level window,

    if isAlive(aWindow): ...

which is useful for SDI applications when a top-level window might have
been deleted (e.g., closed by the user) while you still have a reference
to it (e.g., a list of open windows).

How d'you check whether an object reference refers to a real existing
object in PySide?

Thanks!
