The following illustrates using MouseListener for AWT Frame. MouseListener listens to MouseEvent such as mousePressed, mouseReleased, mouseClicked, mouseEntered, mouseExited.
To see the effect of mouseReleased(), try pressing the mouse at a point and releasing it at another point.
mouseClicked() means pressing and releasing a mouse button at the same point. mouseEntered() and mouseExited() are executed when the cursor enters and exits the frame respectively.
FrameMouseEvent(): This contains code that illustrates use of MouseListener with AWT Frame.
new FrameMouseEvent(): Creates an object for the FrameMouseEvent class.
