Hi,
In the ScrollableThumbnail class, when deactivate() is called, the
super.deactivate() declared in Thumbnail - in turn calls
updater.deactivate().
The ThumbnailUpdater class deactivate() method calls dispose on the
Thumbnail image.
public void deactivate() {
setActive(false);
stop();
if (thumbnailImage != null) {
thumbnailImage.dispose();
thumbnailImage = null;
thumbnailImageSize = null;
}
}
When you create an instance of ScrollableThumbnail, a SelectorFigure is
created in the initialize method. This SelectorFigure also has an
image. This image is disposed of in the finalize method.
Is there a reason as to why these two ScrollableThumbnail specific
images are being disposed of at different times? Why would they not
both be disposed of on deactivate?
Regards,
Stephanie
