title: Changing value of boolean when mouse cursor hovers over a JButton
body: <p>I have a button that will change from black to gray when you hover over, I do this with <code>setRolloverIcon(ImageIcon);</code>. Is there any easy way to make a boolean equals to true while the mouse cursor hovers over the JButton or would I have to use a MouseMotionListener to check the position of the mouse cursor?</p>
