Package Summary  Overview Summary

class:ImageIcon [CHANGED]
  • All Implemented Interfaces:
    Serializable, Accessible, Icon 

    public class ImageIcon
extends Object
implements Icon, Serializable, Accessible
    An implementation of the Icon interface that paints Icons from Images. Images that are created from a URL, filename or byte array are preloaded using MediaTracker to monitor the loaded state of the image.

    For further information and examples of using image icons, see How to Use Icons in The Java Tutorial.

    Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

field:component [NONE]

  • component

    @Deprecated
protected static final Component component
    Deprecated. since 1.8
    Do not use this shared component, which is used to track image loading. It is left for backward compatibility only.

  • ImageIcon

    public ImageIcon(String filename,
                 String description)
    Creates an ImageIcon from the specified file. The image will be preloaded by using MediaTracker to monitor the loading state of the image.
    Parameters:
    filename - the name of the file containing the image

    @ConstructorProperties(value="description")
public ImageIcon(String filename)
    Creates an ImageIcon from the specified file. The image will be preloaded by using MediaTracker to monitor the loading state of the image. The specified String can be a file name or a file path. When specifying a path, use the Internet-standard forward-slash ("/") as a separator. (The string is converted to an URL, so the forward-slash works on all systems.) For example, specify:
        new ImageIcon("images/myImage.gif")
    The description is initialized to the filename string.
    Parameters:
    filename - a String specifying a filename or path

    Creates an ImageIcon from an array of bytes which were read from an image file containing a supported image format, such as GIF, JPEG, or (as of 1.3) PNG.
