The problem is not switching between the image and the custom widget,
although your suggestion does seem to be clear than what I am doing
right now. Even if I were to replace the parent widget (which wrappers
the custom widget) with a QStackedWidget, to disable the custom widget
I would have to disable the QStackedWidget, since I want the entire
process to be transparent.
