Constructors

o AALinePanel 
 public AALinePanel()
Constructs an AALinePanel.

Methods

o handleEvent 
 public boolean handleEvent(Event event)
Process any events associated with the editable fields of this object.

Overrides:
handleEvent in class Component
o setLineEndPoints 
 public void setLineEndPoints(Point p1,
                              Point p2)
Update the two endpoints text fields in this object.

o getLineEndPoints 
 public boolean getLineEndPoints(Point p1,
                                 Point p2)
Modifies the given Point parameters with the current value of the line endpoint textfields.

Returns:
Returns false unless all four of the endpoint textfields are valid integers. On failure the resulting values in p1 and p2 are unpredictable.
