public class DirectPaintingSWTAlignmentArea
extends AbstractSWTAlignmentArea
implements ToolkitSpecificAlignmentArea

A toolkit-specific alignment area that implements scrolling via direct painting for SWT.

In contrast to ScrollContainerSWTAlignmentArea this implementation uses DirectPaintingSWTAlignmentContentScroller instead of ScrolledComposite, which makes use of DirectPaintingSWTScrollContainer from TIC. ScrolledComposite currently (2017) has limitations under Windows and Linux in the maximum size of the scrolled content. This implementation is offered as an alternative to overcome these limitations. The methods to provide scrolling functionality are delegated to the nested DirectPaintingSWTAlignmentContentScroller instance.

In contrast to the ScrollContainerSWTAlignmentArea and its Swing counterpart this implementation will not create a toolkit component with its subcomponents for AlignmentContentArea that is then scrolled but will paint the contents of the TIC component directly with an offset according to the current scroll position.
