Class BaseExpressionView

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JPanel
                  org.problets.domain.view.AbstractView
                      org.problets.domain.model.expression.view.BaseExpressionView

All Implemented Interfaces:

java.awt.event.ActionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible, GUIConstants

Direct Known Subclasses:

ExpressionProblemView, ExpressionTutorView

public class BaseExpressionView
extends AbstractView
implements GUIConstants

To display the expression, and provide for displaying underbraces. It will also solve the expression and prepare the graphical answer using underbraces ExpressionTutorView and ExpressionProblemView inherit from this. This class could handle centering the expression - by recalculating X_START and Y_START and re-assigning to spacing/SPACING
