org.eclipse.swt.graphics
Class ImageLoaderEvent  

java.lang.Object
  java.util.EventObject
      org.eclipse.swt.internal.SWTEventObject
          org.eclipse.swt.graphics.ImageLoaderEvent

All Implemented Interfaces:

java.io.Serializable

---

public class ImageLoaderEvent

extends org.eclipse.swt.internal.SWTEventObject

Instances of this class are sent as a result of the incremental loading of image data.

Notes:

• The number of events which will be sent when loading images is not constant. It varies by image type, and for JPEG images it varies from image to image.
• For image sources which contain multiple images, the endOfImage flag in the event will be set to true after each individual image is loaded.

---

Field Summary
boolean	endOfImage           If this flag is true, then the current image data has been completely loaded, otherwise the image data is only partially loaded, and further ImageLoader events will occur unless an exception is thrown
ImageData	imageData           if the endOfImage flag is false, then this is a partially complete copy of the current ImageData, otherwise this is a completely loaded ImageData
int	incrementCount           the zero-based count of image data increments -- this is equivalent to the number of events that have been generated while loading a particular image
