public class DefaultDrawing
extends AbstractDrawing

A default implementation of Drawing useful for drawings which contain only a few figures.

For larger drawings, QuadTreeDrawing is recommended.

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

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 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 children of composite figures.

Use Drawing.findFigureInside(java.awt.geom.Point2D.Double) If you need to descend into children of composite figures.

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

public Figure findFigureExcept(java.awt.geom.Point2D.Double p,
                               java.util.Collection<? extends 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.

findFigures

public java.util.List<Figure> findFigures(java.awt.geom.Rectangle2D.Double bounds)

Description copied from interface: Drawing

Returns all figures that lie within or intersect the specified bounds. The figures are returned in Z-order from back to front.

findFiguresWithin

public java.util.List<Figure> findFiguresWithin(java.awt.geom.Rectangle2D.Double bounds)

Description copied from interface: Drawing

Returns all figures that lie within the specified bounds. The figures are returned in Z-order from back to front.

findFigureInside

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

Description copied from interface: Figure

Finds the innermost figure at the specified location.

In case of a CompositeFigure, this method descends into its children and into its children's children until the innermost figure is found.

This functionality is implemented using the Chain of Responsibility design pattern. A figure which is not composed of other figures returns itself if the point is contained by the figure. Composed figures pass the method call down to their children.

Specified by:

findFigureInside in interface Drawing

Specified by:

findFigureInside in interface Figure

Overrides:

findFigureInside in class AbstractCompositeFigure

Parameters:

p - A location on the drawing.

Returns:

Returns the innermost figure at the location, or null if the location is not contained in a figure.

getFiguresFrontToBack

public java.util.List<Figure> getFiguresFrontToBack()

Returns an iterator to iterate in Z-order front to back over the children.

setAttributeOnChildren

protected void setAttributeOnChildren(AttributeKey key,
                                      java.lang.Object newValue)

Overrides:

setAttributeOnChildren in class AbstractAttributedCompositeFigure

indexOf

public int indexOf(Figure figure)

Description copied from interface: CompositeFigure

Returns the index of the specified child.

This is a convenience method for calling getChildren().indexOf(index);.

Specified by:

indexOf in interface CompositeFigure

Overrides:

indexOf in class AbstractCompositeFigure

Returns:

The index of the child, or -1 if the specified figure is not a child of this CompositeFigure.

drawFill

protected void drawFill(java.awt.Graphics2D g)

Description copied from class: AbstractAttributedCompositeFigure

This method is called by method draw() to draw the fill area of the figure. AttributedFigure configures the Graphics2D object with the FILL_COLOR attribute before calling this method. If the FILL_COLOR attribute is null, this method is not called.

Specified by:

drawFill in class AbstractAttributedCompositeFigure

drawStroke

protected void drawStroke(java.awt.Graphics2D g)

Description copied from class: AbstractAttributedCompositeFigure

This method is called by method draw() to draw the text of the figure . AttributedFigure configures the Graphics2D object with the TEXT_COLOR attribute before calling this method. If the TEXT_COLOR attribute is null, this method is not called.

Specified by:

drawStroke in class AbstractAttributedCompositeFigure

drawCanvas

public void drawCanvas(java.awt.Graphics2D g)

Description copied from interface: Drawing

Draws on the canvas area. The canvas is the background area onto which the drawing is drawn.

By convention this method is only invoked by DrawingView.

AttributeKeys defines a number of attribute keys which can be used to determine what to draw on the canvas.
