public class PNGImage
extends com.google.gwt.user.client.ui.Image

Image widget that overcomes PNG browser incompatabilities. Although meant for PNG images, it will work with any image format supported by the browser. If the image file ends with ".png" or ".PNG" it will use the PNG specific routines, otherwise will use generic non-PNG specific routines. The URL, width, and height are required at the creation of the widget, and may not be updated via the widget methogs. Calling setUrl() will throw a RuntimeException. This is in part due to the workarounds required for IE 5.5 and IE6.
