All Implemented Interfaces:

ReplacedElement

public class DeferredImageReplacedElement
extends ImageReplacedElement

An DeferredImageReplacedElement is a ReplacedElement that contains a Image which by default is simply a transparent image scaled to the size provided to the constructor. The DeferredImageReplacedElement also has a reference to an ImageResource which points to the image which will be returned for this replaced element. That Image may be loaded some time after this DeferredImageReplacedElement is created. Calling getImage() on instances of DeferredImageReplacedElement will return either the original dummy image, or the actual image loaded into the ImageResource.

Constructor Detail

DeferredImageReplacedElement

public DeferredImageReplacedElement(ImageResource imageResource,
                                    RepaintListener repaintListener,
                                    int w,
                                    int h)

Creates a new ImageReplacedElement and scales it to the size specified if either width or height has a valid value (values are > -1), otherwise original size is preserved. The idea is that the image was loaded at a certain size (that's the Image instance here) and that at the time we create the ImageReplacedElement we have a target W/H we want to use.

Parameters:

imageResource -

repaintListener -
