Hello,

You must use MouseListener interface for java.awt.event package.
When you implement this interface in your class, you'll see
two methods: mouseEntered(MouseEvent) and mouseExited(MouseEvent)
first is called when mouse cursor is over your component, second- when cursor leaves your component.
don't forget to add listener to image component(canvas, panel), like imageCmp.addMouseListener(yourListener).

Ivan.
