title: Detecting mouse enter/exit events anywhere on JPanel
body: <p>Basically there is a JPanel on which I want to know when the mouse enters the area of the JPanel and exits the area of the JPanel.  So I added a mouse listener, but if there are components on the JPanel and the mouse goes over one of them it is detected as an exit on the JPanel, even though the component is on the JPanel.  I was wondering whether anyone knows any way to solve this problem without doing something like adding listeners onto all components on the JPanel?</p>
