wjhk.jupload2.gui.PicturePanel
- All Implemented Interfaces:
- ComponentListener, MouseListener, ImageObserver, MenuContainer, Serializable, EventListener, Accessible
- Direct Known Subclasses:
- DialogPicturePanel
public class PicturePanel
- extends Canvas
- implements MouseListener, ComponentListener
This panel is used to preview picture, when PictureUploadPolicy (or one of
its inherited policy) is used. Manages the panel where pictures are
displayed.
Each time a user selects a file in the panel file, the PictureUploadPolicy
calls
setPictureFile(PictureFileData, AbstractButton, AbstractButton). I
did an attempt to store the Image generated for the Panel size into the
PictureFileData, to avoid to calculate the offscreenPicture each time the
user select the same file again. But it doesn't work: the applet quickly runs
out of memory, even after numerous calls of System.gc and finalize.
