PyQt4 is a set of Python bindings for [http://www.trolltech.com/products/qt Qt 4] that exposes much of the functionality of Qt 4 to Python, including:

• A comprehensive set of widgets
• Flexible layout managers
• Standard GUI features for applications (menus, toolbars, dock windows)
• Easy communication between application components (signals and slots)
• A unified painting system with transparency, anti-aliasing, OpenGL integration and SVG support

• Internationalization (i18n) support and integration with the [http://www.trolltech.com/products/qt/features/internationalization Qt Linguist] translation tool

• Rich text processing, display and printing facilities, including support for PDF export (Qt 4.1 and later)
• Database support (SQL) and model/view features
• Threading classes, providing abstractions for threads, mutexes and semaphores
• Integrated resource handling for applications
• Widget styles, including support for widget stylesheets (from Qt 4.2 onwards)
• Input/output and networking
  • Qt 4.3 and later supports Secure Sockets Layer communications
• A graphics canvas (Qt 4.2 and later)
• Inter-process communication for Unix (D-Bus in Qt 4.2 and later)
• Text completion and undo frameworks (Qt 4.2 and later)
• XML handling APIs, including SAX, DOM and (from Qt 4.3 onwards) a stream-oriented API
