To handle window events, check the event queue for new events and call attached handlers. Once an event handler finishes processing an event, it passes the event to the next handler. But if the handler returns EVENT_HANDLED, the event stops going any further.  

 

To start the main event loop, use pyglet.app.run. When you close all windows, it will finish. A commonly used event dispatcher is pyglet.window. The event dispatcher queues relevant events. Then, generate the handlers and call them in the order. 

 

Using the methods above to attach an event handler to a dispatcher will replace the current handler. The original handler will no longer receive calls. You can use images, video, and sound files in different formats. You can add the optional plugin to get more features. It supports audio formats and Windows Media Audio.
