A PyQt backend enables the integration of Traits and TraitsGUI - Pyface software, providing a robust interface for the development of advanced GUI applications.
Luckily, the TraitsGUI project comes with a GUI abstraction layer called Pyface that is independent of any particular toolkit. Pyface is what you'll use to create "visualization" features for your Traits-based objects. Essentially, this tool enables programmers to interact with generic GUI objects (such as an "MDI Application Window") instead of working with raw GUI widgets.
While Traits and Pyface are separate from any specific toolkit, they still require the use of a supported Python-based GUI toolkit and the appropriate toolkit-specific backend project. Currently, TraitsBackendQt works well with PyQt and wxPython. It's important to note that both Enthought.pyface.ui.qt4 and Enthought.traits.ui.qt4 are licensed under the Gnu Public License, and if you're using Qt to develop software, you'll need to choose the appropriate license from TrollTech. The good news is that you can create user interfaces with TraitsGUI and your chosen toolkit and backend without having to worry about the details – you can simply write code using the Traits API and let the software handle the rest.
