public class VisualGraphObjectSwtRepositoryItem

extends AbstractSwtRepositoryItem

The VisualGraphObjectSwtRepositoryItem is used to display a VisualGraphObject in an SWT context.

Additionally to display the VisualGraphObject this VisualGraphObjectSwtRepositoryItem enables the drag and drop mechanism such that the VisualGraphObject can be dragged out of the repository item and dropped onto any appropriate control.
