# The pyglet event framework

The pyglet.window, pyglet.media, pyglet.app and pyglet.text modules make use of a consistent event pattern, which provides several ways to attach event handlers to objects. You can also reuse this pattern in your own classes easily.

Throughout this documentation, an "event dispatcher" is an object that has events it needs to notify other objects about, and an "event handler" is some code that can be attached to a dispatcher.
