Method Details

  Parameters:

  width - icon width

• toImageIcon

  public static ImageIcon toImageIcon(Icon icon)

  Returns an ImageIcon based on a given Icon object. If the supplied icon is already an ImageIcon, it is returned. Otherwise, it is painted to an Image and an ImageIcon is constructed from that.

  image icon
