JButton creates a button by pasting a circular image.

  • Circular, the same size of PNG is an image (outside of the circle is transparent color) providing three types JButton set to
  1. setIcon
  2. setPressedIcon
  3. setRolloverIcon
  4. setContentAreaFilled (false) Set the like, it does not draw the button itself
  • Recommended, to match the minimum, maximum size to the size of the image
  1. However, to draw a line edge, from vertical and horizontal image size 1px larger as EmptyBorder has set
  • It contains Override, if you click on the outside of the circle button so as not to react
  1. In this sample, and not necessarily that is generating the circle from the transmission color of the image, and prepares separate circular shapes the size of the image
  2. From the image of the transparent color, to set a clickable area, change the shape definition of the JComponent see
  • paintBorder Override, original edge to draw your own circle with a line of its width without drawing
