Events are what happen in TK when a button is pressed, the cursor moves over your window, or your window resizes...amongst other things. Some events (such as a subtle change of colour as you move over a button) are provided by default. You provide action for other events (such as button presses) when you define the button, and there's a final class of events that you can add once you've completed definition of a widget. In this module, you'll learn how to define your own events handlers, bind them to particular events, override system events if need be, and more.
