618 Chapter 16 Event-Driven Programming This constructs a Point object with the specified x- and y-coordinates. Normally, the data fields in a class should be private, but this class has two public data fields. Java provides two listener interfaces, MouseListener and MouseMotionListener, to handle mouse events, as shown in Figure 16.13. Implement the MouseListener interface to listen for such actions as pressing, releasing, entering, exiting, or clicking the mouse, and implement the MouseMotionListener interface to listen for such actions as dragging or moving the mouse. «interface» java.awt.event.MouseListener +mousePressed(e: MouseEvent): void +mouseReleased(e: MouseEvent): void +mouseClicked(e: MouseEvent): void +mouseEntered(e: MouseEvent): void +mouseExited(e: MouseEvent): void Invoked after the mouse button has been pressed on the source component. Invoked after the mouse button has been released on the source component. Invoked after the mouse button has been clicked (pressed and released) on the source component. Invoked after the mouse enters the source component. Invoked after the mouse exits the source component. «interface» java.awt.event.MouseMotionListener +mouseDragged(e: MouseEvent): void +mouseMoved(e: MouseEvent): void Invoked after a mouse button is moved with a button pressed. Invoked after a mouse button is moved without a button pressed. FIGURE 16.13 The MouseListener interface handles mouse pressed, released, clicked, entered, and exited events. The MouseMotionListener interface handles mouse dragged and moved events. To demonstrate using mouse events, we give an example that displays a message in a panel and enables the message to be moved using a mouse. The message moves as the mouse is dragged, and it is always displayed at the mouse point. Listing 16.8 gives the program. A sample run of the program is shown in Figure 16.14. FIGURE 16.14 You can move the message by dragging the mouse.
