public class ZRectangle

extends ZShape

ZRectangle is a graphic object that represents a hard-cornered rectangle.

Warning: Serialized and ZSerialized objects of this class will not be compatible with future Jazz releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Jazz. A future release of Jazz will provide support for long term persistence.

Constructor Detail

ZRectangle

public ZRectangle()

Constructs a new Rectangle.

ZRectangle

public ZRectangle(double x,
                  double y)

Constructs a new Rectangle at the specified location, with dimensions of zero.

Parameters:

x - X-coord of top-left corner

y - Y-coord of top-left corner

ZRectangle

public ZRectangle(double x,
                  double y,
                  double width,
                  double height)

Constructs a new Rectangle at the specified location, with the given dimensions.

Parameters:

x - X-coord of top-left corner

y - Y-coord of top-left corner

width - Width of rectangle

height - Height of rectangle

ZRectangle

public ZRectangle(java.awt.geom.Rectangle2D r)

Constructs a new Rectangle based on the geometry of the one passed in.

Parameters:

r - A rectangle to get the geometry from

Method Detail

duplicateObject

protected java.lang.Object duplicateObject()

Returns a clone of this object.

Overrides:

duplicateObject in class ZBasicVisualComponent

See Also:

ZSceneGraphObject.duplicateObject()

getRect

public java.awt.geom.Rectangle2D getRect()

Return the rectangle.

Returns:

rectangle.

getShape

public java.awt.Shape getShape()

Return the shape.

Overrides:

getShape in class ZShape

Returns:

Shape.

setRect

public void setRect(double x,
                    double y,
                    double width,
                    double height)

Sets location and size of the rectangle.

Parameters:

x - X-coord of top-left corner

y - Y-coord of top-left corner

width - Width of rectangle

height - Height of rectangle

setRect

public void setRect(java.awt.geom.Rectangle2D r)

Sets coordinates of rectangle.

Parameters:

r - The new rectangle coordinates

setPenWidth

public void setPenWidth(double width)

Set the width of the pen used to draw the visual component. If the pen width is set here, then the stroke is set to solid (un-dashed), with a "butt" cap style, and a "bevel" join style. The pen width will be dependent on the camera magnification.

Overrides:

setPenWidth in class ZBasicVisualComponent

Parameters:

width - the pen width.

See Also:

ZBasicVisualComponent.setAbsPenWidth(double)

writeObject

public void writeObject(ZObjectOutputStream out)
                 throws java.io.IOException

Write out all of this object's state.

Overrides:

writeObject in class ZBasicVisualComponent

Parameters:

out - The stream that this object writes into

setState

public void setState(java.lang.String fieldType,
                     java.lang.String fieldName,
                     java.lang.Object fieldValue)

Set some state of this object as it gets read back in. After the object is created with its default no-arg constructor, this method will be called on the object once for each bit of state that was written out through calls to ZObjectOutputStream.writeState() within the writeObject method.

Overrides:

setState in class ZBasicVisualComponent

Parameters:

fieldType - The fully qualified type of the field

fieldName - The name of the field

fieldValue - The value of the field
