                       double padding,
                       int anchor)

Method Detail

transform

public void transform(AffineTransform at)

Description copied from class: LabelFigure

Transform the label with the given transform. Note that the anchor of the figure will appear to move -- use translateTo() to move it back again if this method being called to (for example) rotate the label.

Specified by:

transform in interface Figure

Overrides:

transform in class LabelFigure

translate

public void translate(double x,
                      double y)

Description copied from class: AbstractFigure

Move the figure the indicated distance. The default implementation uses the transform method, so most subclasses can probably implement this more efficiently.

Specified by:

translate in interface Figure

Overrides:

translate in class AbstractFigure

setShape

public void setShape(Shape shape)

Description copied from interface: DrawFigure

Set the Figure shape.

Specified by:

setShape in interface DrawFigure

setLineWidth

public void setLineWidth(float lineWidth)

Description copied from interface: DrawFigure

All Figures have a line width.

Specified by:

setLineWidth in interface DrawFigure

getLineWidth

public float getLineWidth()

Description copied from interface: DrawFigure

Get the line width.

Specified by:

getLineWidth in interface DrawFigure

setStrokePaint

public void setStrokePaint(Paint outline)

Description copied from interface: DrawFigure

All Figures have an outline colour.

Specified by:

setStrokePaint in interface DrawFigure

getStrokePaint

public Paint getStrokePaint()

Description copied from interface: DrawFigure

Get the outline.

Specified by:

getStrokePaint in interface DrawFigure

setTransformFreely

public void setTransformFreely(boolean state)

Description copied from interface: DrawFigure

Enable the hint that a figure should allow itself to transform freely, rather than obey any constraints (this is meant for figures that could not otherwise redraw themselves to fit a resized Draw, given their normal constraints, e.g. XRangeFigure).

Specified by:

setTransformFreely in interface DrawFigure

isTransformFreely

public static boolean isTransformFreely()

Find out if this is an occasion when a figure should give up any constraints and transform freely.

addListener

public void addListener(FigureListener l)

Registers a listener for to be informed when figure changes occur.

Specified by:

addListener in interface DrawFigure

Parameters:

l - the FigureListener

removeListener

public void removeListener(FigureListener l)

Remove a listener.

Specified by:

removeListener in interface DrawFigure

Parameters:

l - the FigureListener

fireCreated

protected void fireCreated()

Send a FigureChangedEvent object specifying that this figure has created to all listeners.

fireRemoved

protected void fireRemoved()

Send a FigureChangedEvent object specifying that this figure has been removed.

fireChanged

protected void fireChanged()

Send a FigureChangedEvent object specifying that this figure has changed.
