      Description



      Name: rk38400 Date: 04/07/98


      The problem is that JRadioButtons with Icons look pretty strange.
      The behaviour that I would expect is that the buttons should size
      themself after the icons. The way it currently works is that the
      Image is off-center, hiding the left edge of the icon, and there
      are 'insets' top, under and right making the button much bigger
      than it should be.
      The problem was there under swing-0.7 as well, but much less
      severe. I don't remember it under swing-0.6.1 .

      The code supplied demonstrates this.
      Note that the Icons are actually square, but the left edge is
      hidden by the border.

      To compile:

      Copy the code to a file called JButtonBug.java, and compile
      with:
      >javac JButtonBug.java

      Make sure swing is in your classpath.
