TraitsUI - Traits-capable windowing framework
TraitsUI is a Python user interface toolkit that provides a declarative approach to building interactive GUIs. It automatically generates user interfaces from declarative object definitions using the Traits type system. TraitsUI supports multiple GUI backends including Qt and wxPython, allowing developers to create cross-platform desktop applications with minimal code. The framework is particularly well-suited for scientific and engineering applications where rapid prototyping and data visualization are important.
