A simple -- and not very realistic -- event dispatcher might look a lot like the act method of AnimateAlarm. But sometimes you will know that it is necessary for a GUI object to repaint itself. A timer might generate the timeout events and deposit them into the queue.

So there will be times when your code will be given a Graphics to use. We will return to the question of precisely how this can be accomplished later in this chapter. However, each time that your Canvas needs to redisplay itself, it will be handed a Graphics context with which to do that redisplaying.

In this section, we will take a look at the package java. These are things that appear on your screen, like windows and buttons. The event that we will be concerned with here is painting.

In the case of the Alarm, we would not have to write the act method or switch statement above at all. This is not necessary in the event systems of this chapter, where there is a single event queue per handler object, but provides yet another layer of flexibility.

We will make a Canvas that paints itself with a special picture. Method invocation does not change which instruction follower is executing.

A separate instruction follower, the event dispatcher, would discover the timeout event in the queue and invoke the handleTimeout method of the relevant party.

A graphical user interface -- sometimes called a GUI, pronounced "gooey" -- is a visual display containing windows, buttons, text boxes, and other "widgets". Component has an event-driven paint method. This method has nothing to do with determining that painting is necessary.

The parent of all component classes is java. Or, to paint me, paint each of the Components that appear inside me. To paint me, make a big red dot. Press the little "Windows flag" button found to the leftside of your keyboard, in between the ctrl and alt buttons.

Components A component is a thing that can appear on your screen, like a window or a button.
