Class ImageIcon

java.lang.Object

vaadinx.swing.ImageIcon

All Implemented Interfaces:

Serializable, Accessible, Icon

public class ImageIcon
extends Object
implements Icon, Serializable, Accessible

Emulator for ImageIcon. Holds a JDK-side ImageIcon delegate so all the load-from-file / load-from-bytes / load-from-URL / load-from-Image construction shapes Just Work, and so getImage() hands back a real Image the icon-rendering bridge can encode.

Implements Icon (paintIcon's signature references Component, which is why we can't reuse javax.swing.ImageIcon directly under D_whitelist_porting's port rule). The paintIcon body itself is a EHelper.onUnimplemented(String, String, Object...) stub — Path 3 (offscreen-paint of arbitrary Icon impls) is deferred; ImageIcon's data path is Path 1 and lives in the icon-rendering bridge, not in this class.

Construction shapes match javax.swing.ImageIcon verbatim, so post-import-swap user code (e.g. new ImageIcon("logo.png")) compiles unchanged.

Adapter ctor: wrap an existing ImageIcon. Used by the icon-rendering bridge to forward the raster without re-loading from source.

Method Details

getImage

public Image getImage()

setImage

public void setImage(Image image)

getDescription

public String getDescription()

setDescription

public void setDescription(String description)

getImageLoadStatus

public int getImageLoadStatus()

getImageObserver

public ImageObserver getImageObserver()

setImageObserver

public void setImageObserver(ImageObserver observer)

getIconWidth

public int getIconWidth()

Specified by:

getIconWidth in interface Icon

getIconHeight

public int getIconHeight()

Specified by:

getIconHeight in interface Icon

paintIcon

public void paintIcon(Component c,
 Graphics g,
 int x,
 int y)

Specified by:

paintIcon in interface Icon

asJdk

public ImageIcon asJdk()

Accessor for the underlying JDK ImageIcon. The icon-rendering bridge in EHelper uses this to hand the raw raster to the surrogate-layer encoder; user code can also call it when migrating away from the vaadinx.swing.ImageIcon port back to JDK types.

toString

public String toString()

Overrides:

toString in class Object

getAccessibleContext

public AccessibleContext getAccessibleContext()

Specified by:

getAccessibleContext in interface Accessible
