Transparent JButton

Buttons are specific in the context of transparency - in order to make them transparent, you do not call setOpaque(false), but instead you have to do three things - remove margins, remove border and prevent filling of the content area (this should have been actually controlled by the opaque property, but it is not). Here is a snippet that does everything:

Insets noInsets=new Insets(0,0,0,0);
// store the icon you want to display in imageIcon	
JButton buttonHelp=new JButton(imageIcon);	
buttonHelp.setMargin(noInsets);			
buttonHelp.setBorder(BorderFactory.createEmptyBorder());
buttonHelp.setContentAreaFilled(false);
