Class ImageLoaderEvent
java.lang.Object
|
+--java.util.EventObject
|
+--org.eclipse.swt.internal.SWTEventObject
|
+--org.eclipse.swt.graphics.ImageLoaderEvent
- All Implemented Interfaces:
- 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 |
Constructor Summary |
ImageLoaderEvent(ImageLoader source,
ImageData imageData,
int incrementCount,
boolean endOfImage)
Constructs a new instance of this class given the event source and
the values to store in its fields. |
Method Summary |
String |
toString()
Returns a string containing a concise, human-readable
description of the receiver. |
imageData
public 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
incrementCount
public 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
endOfImage
public 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
ImageLoaderEvent
public ImageLoaderEvent(ImageLoader source,
ImageData imageData,
int incrementCount,
boolean endOfImage)
- Constructs a new instance of this class given the event source and
the values to store in its fields.
- Parameters:
source
- the ImageLoader that was loading when the event occurredimageData
- the image data for the eventincrementCount
- the image data increment for the eventendOfImage
- the end of image flag for the event
toString
public String toString()
- Returns a string containing a concise, human-readable
description of the receiver.
- Overrides:
toString
in class EventObject
- Returns:
- a string representation of the event
