Scrolling: JViewport, JScrollPane, and Related Classes

New JViewport scrollMode Property
Interactive scrolling speed has proven to be perhaps the most important factor in users perception of overall swing performance. 1.3 adds a new optimization, called "BLIT_SCROLL_MODE" (now the default) that copies unobscured areas of the components heavy weight ancestor to effect a scroll. Previously we had offered a related optimzation that managed a per viewport backing store image. Although still supported, the backingStoreEnabled property has been deprecated.
See:
public static final int BLIT_SCROLL_MODE public static final int BACKINGSTORE_SCROLL_MODE public static final int SIMPLE_SCROLL_MODE public void setScrollMode(int mode) public int getScrollMode() protected boolean backingStore // Deprecated public boolean isBackingStoreEnabled() // Deprecated
public void setBackingStoreEnabled(boolean enabled) // Deprecated
