  • Method Details

    • emptyIcon

      public static Icon emptyIcon(int width, int height)
      Returns an icon with a given size and no content.
      Parameters:
      width - icon width
      height - icon height

    • colorIcon

      public static Icon colorIcon(Icon icon, Color color)
      Modifies an existing icon by changing its colour. The colour attribute of the graphics context is changed before the icon is painted.
      Parameters:
      icon - input icon
      color - colour to use as default for painting
      Returns:
      output icon

    • 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. The reason this is useful is that some Swing components will only grey out disabled icons if they are ImageIcon subclasses (which is naughty).
      Parameters:
      icon - input icon
      Returns:
      image icon

    • createTextIcon

      public static Icon createTextIcon(String line, Graphics g)
      Returns an icon that paints a line of text.
      Parameters:
      line - text string
      g - graphics context
      Returns:
      icon

    • createImage

      public static BufferedImage createImage(Icon icon)
      Returns an image got by drawing an Icon.
      Parameters:
      icon - icon
      Returns:
      image
