Not the parent, but a tree view is convenient for an app that has a lot of settings. For instance you can take a dictionary of settings and create a tree view with the same structure. If a setting gets added later, you don't need to rearrange the GUI, it rearranges itself. I've seen this kind of GUI in programs that manage complicated hardware such as scientific instrumentation.
