All Implemented Interfaces:

BBDisplay, StrokeDataListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class BasicSurface
extends SurfaceView
implements BBDisplay, StrokeDataListener

Since this is a SketchPanel other classes can register to listen for new stroke events that it will fire when it detects new inputs.

Method Detail

displayBB

public void displayBB(Blackboard bb,
                      boolean isRecognizing)

This method should only be called by the Scheduler when it has determined that the BB is in a consistant state. This avoids rendering a partially interpreted sketch.

Specified by:

displayBB in interface BBDisplay

Specified by:

displayBB in class SurfaceView

paintSurface

public void paintSurface(java.awt.Graphics g)

Paint the game thus far.

Specified by:

paintSurface in class SurfaceView

paintStrokes

public void paintStrokes(java.awt.Graphics g)

moving

public void moving(java.lang.Object item,
                   int dx,
                   int dy)

Description copied from class: SurfaceView

Update whatever needs to be updated while we are in the process of moving the given item. This will be the item returned by the findObjectAt method when the move is initiated.

This should usually only update the display of the element and should not trigger any actions by the recognition system.

Specified by:

moving in class SurfaceView

doneMoving

public void doneMoving(java.lang.Object item,
                       java.awt.Point startPos,
                       java.awt.Point endPos)

Description copied from class: SurfaceView

The move has been completed. The recognition system should be updated so that it can interprete the new state of affairs. XXX: this means reevaluating constraints that the moved item is part of.

Specified by:

doneMoving in class SurfaceView

findObjectAt

public java.lang.Object findObjectAt(java.awt.Point point)

Description copied from class: SurfaceView

Find the object that is located under the given point. This will be used to determine which object should be moved.

Specified by:

findObjectAt in class SurfaceView

handleStroke

public void handleStroke(StrokeData data)

Description copied from interface: StrokeDataListener

This method is called by classes that collect StrokeData objects.

Specified by:

handleStroke in interface StrokeDataListener
