Class ImageLoaderEvent

java.lang.Object
java.util.EventObject
org.eclipse.swt.graphics.ImageLoaderEvent
All Implemented Interfaces:
Serializable
public class ImageLoaderEvent extends EventObject
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

    Fields
    Modifier and Type
    Field
    Description
    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
