Method Detail

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.

drawFigure

public void drawFigure(java.awt.Graphics2D g)

Overrides:

drawFigure in class AbstractAttributedCompositeFigure

drawFill

public 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

public 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

invalidate

public void invalidate()

Description copied from class: AbstractFigure

Invalidates cached data of the Figure. This method must execute fast, because it can be called very often.

Overrides:

invalidate in class AbstractCompositeFigure

getPath

protected java.awt.geom.Path2D.Double getPath()

getDrawingArea

public java.awt.geom.Rectangle2D.Double getDrawingArea()

Description copied from interface: Figure

Returns the drawing area of the figure as a Rectangle.

The drawing area is used to inform DrawingView about the area that is needed to draw this figure.

The drawing area needs to be large enough, to take line width, line caps and other decorations into account that exceed the bounds of the Figure.

Specified by:

getDrawingArea in interface Figure

Overrides:

getDrawingArea in class AbstractCompositeFigure

contains

public boolean contains(java.awt.geom.Point2D.Double p)

Description copied from interface: Figure

Checks if a point is contained by the figure.

This is used for hit testing by Tool's.

Specified by:

contains in interface Figure

Overrides:

contains in class AbstractCompositeFigure

setBounds

public void setBounds(java.awt.geom.Point2D.Double anchor,
                      java.awt.geom.Point2D.Double lead)

Description copied from interface: Figure

Sets the logical and untransformed bounds of the figure.

This is used by Tool's which create a new Figure and by Tool's which connect a Figure to another Figure.

This is a basic operation which does not fire events. Use the following code sequence, if you need event firing:

 figure.willChange();
 figure.setBounds(...);
 figure.changed();
 

Specified by:

setBounds in interface Figure

Overrides:

setBounds in class AbstractCompositeFigure

Parameters:

anchor - the start point of the bounds

lead - the end point of the bounds

See Also:

Figure.getBounds()

transform

public void transform(java.awt.geom.AffineTransform tx)

Description copied from class: AbstractCompositeFigure

Transforms the figure.

Specified by:

transform in interface Figure

Overrides:

transform in class AbstractCompositeFigure

Parameters:

tx - The transformation.

See Also:

Figure.getTransformRestoreData(), Figure.restoreTransformTo(java.lang.Object)

restoreTransformTo

public void restoreTransformTo(java.lang.Object geometry)

Description copied from interface: Figure

Restores the transform of the figure to a previously stored state.

Specified by:

restoreTransformTo in interface Figure

Overrides:

restoreTransformTo in class AbstractCompositeFigure

getTransformRestoreData

public java.lang.Object getTransformRestoreData()

Description copied from interface: Figure

Gets data which can be used to restore the transformation of the figure without loss of precision, after a transform has been applied to it.

Specified by:

getTransformRestoreData in interface Figure

Overrides:

getTransformRestoreData in class AbstractCompositeFigure

See Also:

Figure.transform(AffineTransform)

set

public <T> void set(AttributeKey<T> key,
                    T newValue)

Specified by:

set in interface Figure

Overrides:

set in class AbstractAttributedCompositeFigure

See Also:

AttributeKey.set(org.jhotdraw.draw.Figure, T)

setAttributeOnChildren

protected <T> void setAttributeOnChildren(AttributeKey<T> key,
                                          T newValue)

Overrides:

setAttributeOnChildren in class AbstractAttributedCompositeFigure

isEmpty

public boolean isEmpty()

Description copied from interface: ODGFigure

Returns true, if this figure is empty for one of the following reasons:

• A group has no children
• A path has less than two points
• An ellipse or a rectangle has a width or a height of 0
• A text has no characters

Specified by:

isEmpty in interface ODGFigure

createHandles

public java.util.Collection<Handle> createHandles(int detailLevel)

Description copied from interface: Figure

Creates handles used to manipulate the figure.

Specified by:
