I am fiddling around with pyQt and I would like to know if there is a recommended method to change views (like activities in android) in a pyQt app.

Should I delete the widgets on the main window and replace them with others? Is there an object that manages that? That maemo effect where the new view slides in from the right, is there a standard way to do it or do I have to animate it? Should I open new windows, and close the old ones? Any help will be appreciated.
