Java imageicon from file

Java imageicon from file

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 .

component

@Deprecated protected static final Component component

Do not use this shared component, which is used to track image loading. It is left for backward compatibility only.

tracker

@Deprecated protected static final MediaTracker tracker

Do not use this shared media tracker, which is used to load images. It is left for backward compatibility only.

Constructor Detail

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.

ImageIcon

@ConstructorProperties("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")

ImageIcon

public ImageIcon​(URL location, String description)

Creates an ImageIcon from the specified URL. The image will be preloaded by using MediaTracker to monitor the loaded state of the image.

ImageIcon

Creates an ImageIcon from the specified URL. The image will be preloaded by using MediaTracker to monitor the loaded state of the image. The icon’s description is initialized to be a string representation of the URL.

ImageIcon

ImageIcon

Creates an ImageIcon from an image object. If the image has a «comment» property that is a string, then the string is used as the description of this icon.

ImageIcon

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. Normally this array is created by reading an image using Class.getResourceAsStream(), but the byte array may also be statically stored in a class.

ImageIcon

public ImageIcon​(byte[] imageData)

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. Normally this array is created by reading an image using Class.getResourceAsStream(), but the byte array may also be statically stored in a class. If the resulting image has a «comment» property that is a string, then the string is used as the description of this icon.

Method Details

loadImage

getImageLoadStatus

getImage

setImage

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.

setDescription

Sets 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.

paintIcon

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.

getIconWidth

getIconHeight

setImageObserver

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);

getImageObserver

toString

getAccessibleContext

@BeanProperty(expert=true, description=»The AccessibleContext associated with this ImageIcon.») 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.
