Constructor Detail

DrawOval

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

Returns DrawOval which fits into specified rectangle.

Parameters:

x - left edge of the rectangle

y - top edge of the rectange

width - width of the rectangle

height - height of the rectange

Method Detail

paintOperation

public void paintOperation(java.awt.Graphics2D graphics)

Performs grawing operation. This implementation invokes graphics.drawOval ().

Specified by:

paintOperation in class GraphicsOperation

Parameters:

graphics - graphics context to use for painting

getBounds

public java.awt.Rectangle getBounds()

Returns bounding box of the element. If the element is unbounded then this method returns null.

Specified by:

getBounds in interface DrawingElement

Overrides:

getBounds in class AbstractDrawRect

Returns:

bounding box of the element or null is the element is unbounded

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D()

Returns high precision bounding box of the element. If the element is unbounded then this method returns null.

Specified by:

getBounds2D in interface DrawingElement

Overrides:

getBounds2D in class AbstractDrawRect

Returns:

high precision bounding box of the element or null of the element is unbounded

intersects

public boolean intersects(java.awt.geom.Rectangle2D rectangle)

Tests if the element intersects with the given rectangle.

Specified by:

intersects in interface DrawingElement

Overrides:

intersects in class AbstractDrawRect

Parameters:

rectangle - rectangle to be cheched for intersection

Returns:

true if the element intersects with the given rectangle; false otherwase

contains

public boolean contains(java.awt.geom.Point2D point)

Tests if the element containes given point.

Specified by:

contains in interface DrawingElement

Overrides:

contains in class AbstractDrawRect

Parameters:

point - to be checked

Returns:

true if the element contains given point; false otherwise
