All Implemented Interfaces:

public class DefaultDrawing
extends AbstractDrawing

DefaultDrawing to be used for drawings that contain only a few children. For larger drawings, QuadTreeDrawing should be used.

FIXME - Maybe we should rename this class to SimpleDrawing or we should get rid of this class altogether.

Version:

2.2.2 2009-04-04 Adding figures did not invalidate sort order.
2.2.1 Fixed NullPointerException when setting canvas size.
2.2 2007-04-09 Methods setCanvasSize, getCanvasSize added.
2.1 2007-02-09 Moved FigureListener and UndoableEditListener into inner class.
2.0 2006-01-14 Changed to support double precision coordinates.
1.0 2003-12-01 Derived from JHotDraw 5.4b1.

Method Detail

basicAdd

public void basicAdd(int index,
                     Figure figure)

Description copied from interface: CompositeFigure

Adds a child to the figure at the specified index without firing events.

This method can be used to reinsert a child figure which has been temporarily removed from this CompositeFigure (for example to reorder the sequence of the children) and to efficiently build a drawing from an InputFormat.

Specified by:

basicAdd in interface CompositeFigure

Specified by:

basicAdd in interface Drawing

Overrides:

basicAdd in class AbstractCompositeFigure

figure - that is part of the drawing and should be removed

See Also:

Drawing.basicRemove(Figure)

draw

public void draw(java.awt.Graphics2D g)

Description copied from interface: Figure

Draws the figure.

Specified by:

draw in interface Drawing

Specified by:

draw in interface Figure

Overrides:

draw in class AbstractCompositeFigure

Parameters:

g - The Graphics2D to draw to.

draw

public void draw(java.awt.Graphics2D g,
                 java.util.Collection<Figure> children)

sort

public java.util.List<Figure> sort(java.util.Collection<? extends Figure> c)

Description copied from interface: Drawing

Returns a copy of the provided collection which is sorted in z order from back to front.

findFigure

public Figure findFigure(java.awt.geom.Point2D.Double p)

Description copied from interface: Drawing

Finds a top level Figure. Use this call for hit detection that should not descend into the figure's children.

findFigureExcept

public Figure findFigureExcept(java.awt.geom.Point2D.Double p,
                               Figure ignore)

Description copied from interface: Drawing

Finds a top level Figure. Use this call for hit detection that should not descend into the figure's children.

findFigureBehind

public Figure findFigureBehind(java.awt.geom.Point2D.Double p,
                               Figure figure)

Description copied from interface: Drawing

Finds a top level Figure which is behind the specified Figure.

findFigureBehind

public Figure findFigureBehind(java.awt.geom.Point2D.Double p,
                               java.util.Collection<? extends Figure> children)

Description copied from interface: Drawing

Finds a top level Figure which is behind the specified Figures.

findFigureExcept
