ImageIcon (Java Platform SE 8 )

java.lang.Object
- javax.swing.ImageIcon

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.

```
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
    
    description - a brief textual description of the image
    
    See Also:
    
    ImageIcon(String)
  - ImageIcon
```
@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

    image - the image
  - getDescription
```
public String getDescription()
```
    Gets the description of the image. This is meant to be a brief textual description of the object. For example, it might be presented to a blind user to give an indication of the purpose of the image. The description may be null.
    
    Returns:
    
    a brief textual description of the image
  - setDescription
```
public void setDescription(String description)

                      int y)
```
    Paints the icon. The top-left corner of the icon is drawn at the point (x, y) in the coordinate space of the graphics context g. If this icon has no image observer, this method uses the c component as the observer.
    
    Specified by:
    
    paintIcon in interface Icon
    
    Parameters:
    
    c - the component to be used as the observer if this icon has no image observer

    the height in pixels of this icon
  - setImageObserver
```
public void setImageObserver(ImageObserver observer)
```
    Sets the image observer for the image. Set this property if the ImageIcon contains an animated GIF, so the observer is notified to update its display. For example:
```
     icon = new ImageIcon(...)
     button.setIcon(icon);
     icon.setImageObserver(button);
 
```
    Parameters:
    
    observer - the image observer

    Returns a string representation of this image.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representing this image
  - getAccessibleContext
```
public AccessibleContext getAccessibleContext()
```
    Gets the AccessibleContext associated with this ImageIcon. For image icons, the AccessibleContext takes the form of an AccessibleImageIcon. A new AccessibleImageIcon instance is created if necessary.
    
    Specified by:
    
    getAccessibleContext in interface Accessible
    
    Returns:
    
    an AccessibleImageIcon that serves as the AccessibleContext of this ImageIcon
