One simple way to do this is to keep a reference to your UI instance on the
class itself, and replace it each time the UI is instantiated. This has the
added benefit of allowing the UI to be used non-modally for free, since there
will always be a reference to it. You could use a global variable instead, but
the class attribute is a bit more encapsulated.
To clean it up, you could either rely on automatic GC when the instance
reference is replaced, or (depending on how the dialog actually functions
internally) connect its .finished signal to a class method that clears the
reference and maybe even calls its .deleteLater() method for good measure.

Subject: [Nuke-python] Deleting existing PySide UI if it exists
Hi,
I'm creating a simple UI in PySide. Before showing it, I'd like to make sure to
delete any such already existing UI.
I've been having issues finding out how to achieve this.
Has anyone done this and if so, would you like to give some pointers?
Cheers,
Fredrik
