Constructors

ColorWell

  public ColorWell()

Constructs a ColorWell with origin (0, 0) and zero width and height.

ColorWell

  public ColorWell(Rect rect)

Constructs a ColorWell with bounds rect.

ColorWell

  public ColorWell(int x,
                   int y,
                   int width,
                   int height)

Constructs a ColorWell with bounds (x, y, width, height).

Methods

  public void setColor(Color aColor)

Sets the ColorWell's color and then calls draw() to redraw it. If you do not want to immediately redraw the ColorWell, you should first call its disableDrawing() method.

See Also:

disableDrawing

  public Color color()

Returns the ColorWell's color.

See Also:

setColor

  public void setData(Object anObject)

Overridden to enforce setting of Colors only.

Overrides:

setData in class DragWell

See Also:

setColor

  public Image image()

Returns an Image containing the current Color, suitable for dragging.

Overrides:

image in class DragWell

  public void setImage(Image image)

Overriden to throw an error. ColorWells always return an Image representing the current color.

Overrides:

setImage in class DragWell

  public void setDataType(String dataType)

Overriden to throw an error. ColorWells always return a drag type of Color.COLOR_TYPE.

Overrides:

setDataType in class DragWell

  public String dataType()

Returns Color.COLOR_TYPE.

Overrides:

dataType in class DragWell

  public void setTarget(Target aTarget)

Sets the ColorWell's Target, the object the ColorWell notifies when the user drops a Color onto it.

See Also:

performCommand

  public Target target()

Returns the ColorWell's Target.

See Also:

setTarget

  public void setCommand(String command)

Sets the command sent by the ColorWell to its Target when the user drops a Color into it.

See Also:

setTarget

  public String command()

Returns the command sent by the ColorWell to its Target.

See Also:

setCommand

  public void drawView(Graphics g)

Draws the ColorWell by drawing its Border, filled with the ColorWell's color.

Overrides:

drawView in class DragWell

See Also:

setBorder

  public boolean mouseDown(MouseEvent event)

Initiates a drag-session where the user can drag the ColorWell's color, unless the ColorWell is disabled (in which case nothing happens). A double-click in the well invokes the ColorChooser.

Returns:

false if disabled, true otherwise.

Overrides:

mouseDown in class DragWell

See Also:

setEnabled, ColorChooser

  public void mouseDragged(MouseEvent event)

Overridden to support creating a Color drag-session.

Overrides:

mouseDragged in class View

See Also:

mouseDown

  public void mouseUp(MouseEvent event)

Overridden to support creating a Color drag-session.

Overrides:

mouseUp in class View

See Also:

mouseDown

  public DragDestination acceptsDrag(DragSession session,
                                     int x,
                                     int y)

Returns the ColorWell if the DragSession has a data type of Color.COLOR_TYPE, null otherwise.

Overrides:

acceptsDrag in class View

See Also:

dataType

  public boolean dragEntered(DragSession session)

DragDestination support method.

See Also:

dragEntered

  public boolean dragMoved(DragSession session)

DragDestination support method.

See Also:

dragMoved

  public void dragExited(DragSession session)

DragDestination support method.

See Also:

dragExited

  public boolean dragDropped(DragSession session)

Drag-and-drop destination support method, called when the user releases a DragSession's Image over the ColorWell. If the DragSession represents a Color, the ColorWell calls its setColor() method with the dropped Color and sends its command to its Target. If the ColorWell is disabled, or the DragSession doesn't represent a Color, the ColorWell refuses the object. Returns true if the session was accepted, false otherwise.

See Also:

setColor, setEnabled, dragDropped

  public void sendCommand()

Called by the ColorWell to send its command to its Target.

See Also:

setTarget, setCommand

  public void describeClassInfo(ClassInfo info)

Describes the ColorWell class' coding information.

Overrides:

describeClassInfo in class DragWell

See Also:

describeClassInfo

  public void encode(Encoder encoder) throws CodingException

Encodes the ColorWell.

Overrides:

encode in class DragWell

See Also:

encode

  public void decode(Decoder decoder) throws CodingException

Decodes the ColorWell.

Overrides:

decode in class DragWell

See Also:

decode
