Examples of org.tinyuml.draw.Label

org.tinyuml.draw.Label
Label is a representation of a text label with one or more lines. It could in principle be implemented as a JComponent. It is instead opted to keep it as light-weight as possible and integrate it within the DiagramElement hierarchy. @author Wei-ju Wu @version 1.0
