[FIXED] PySide get QObject's parent anywhere in its hierarchy

Issue

Consider I have a class with this kind of structure (CustomClass may/may not be on top of the hierarchy):

CustomClass

.. QTabWidget

.... QWidget

...... QTreeView

In QTreeView I have a function that is trying to refer back to CustomClass. Right now in order to do this I need to do: self.parent().parent().parent().

Although this works it just feels very sloppy, and if I ever need to change the structure this will fail. Is there some other way to get CustomClass? Usually I would pass an instance of it during its constructor which I can call directly, but wondering what's the best practice to go about this.

Solution

This feels like a decent procedural way to get it:

customClassInst = self.parent()
while customClassInst is not None and type(customClassInst) != CustomClass:
    customClassInst = customClassInst.parent()

Any other answers are still welcome :)
