indexOf in class AbstractDrawing

basicAdd

public void basicAdd(int index,
                     Figure figure)

Description copied from interface: Drawing

Reinserts a figure which was temporarily removed using basicRemove. The drawing sends no addNotify message to the figure.

Specified by:

basicAdd in interface Drawing

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

See Also:

Drawing.basicRemove(Figure)

basicRemove

public void basicRemove(Figure figure)

Description copied from interface: Drawing

Removes a figure temporarily from the drawing. The drawing sends no removeNotify message to the figure.

Specified by:

basicRemove in interface Drawing

Parameters:

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

See Also:

Drawing.basicAdd(Figure)

draw

public void draw(java.awt.Graphics2D g)

Description copied from interface: Drawing

Draws all the figures from back to front.

Specified by:

draw in interface Drawing

draw

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

sort

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

Description copied from interface: Drawing

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

Specified by:

sort in interface Drawing

figureAreaInvalidated

public void figureAreaInvalidated(FigureEvent e)

Description copied from interface: FigureListener

Sent when an area used by the figure needs to be repainted.

Specified by:

figureAreaInvalidated in interface FigureListener

figureChanged

public void figureChanged(FigureEvent e)

Description copied from interface: FigureListener

Sent when the geometry (e.g. the bounds) of the figure has changed.

Specified by:

figureChanged in interface FigureListener

figureAdded

public void figureAdded(FigureEvent e)

Description copied from interface: FigureListener

Sent when a figure was added to a drawing.

Specified by:

figureAdded in interface FigureListener

figureRemoved

public void figureRemoved(FigureEvent e)

Description copied from interface: FigureListener

Sent when a figure was removed from a drawing.

Specified by:

figureRemoved in interface FigureListener

figureRequestRemove

public void figureRequestRemove(FigureEvent e)

Description copied from interface: FigureListener

Sent when the figure requests to be removed from a drawing.

Specified by:

figureRequestRemove in interface FigureListener

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.

Specified by:

findFigure in interface Drawing

findFigureExcept

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