Constructor Detail

RoundRectangleFigure

public RoundRectangleFigure()

Creates a new instance.

RoundRectangleFigure

public RoundRectangleFigure(double x,
                            double y,
                            double width,
                            double height)

Method Detail

drawFill

protected void drawFill(java.awt.Graphics2D g)

Description copied from class: AbstractAttributedFigure

This method is called by method draw() to draw the fill area of the figure. AbstractAttributedFigure 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 AbstractAttributedFigure

drawStroke

protected void drawStroke(java.awt.Graphics2D g)

Description copied from class: AbstractAttributedFigure

This method is called by method draw() to draw the text of the figure . AbstractAttributedFigure 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 AbstractAttributedFigure

getBounds

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

Description copied from interface: Figure

Returns the untransformed logical bounds of the figure as a Rectangle.

The bounds are used by Handle objects for adjusting the figure and for aligning the figure on a grid.

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 AbstractAttributedFigure

getArcWidth

public double getArcWidth()

Gets the arc width.

getArcHeight

public double getArcHeight()

Gets the arc height.

setArcWidth

public void setArcWidth(double newValue)

Sets the arc width.

setArcHeight

public void setArcHeight(double newValue)

Sets the arc height.

setArc

public void setArc(double width,
                   double height)

Convenience method for setting both the arc width and the arc height.

contains

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

Checks if a Point2D.Double is inside the figure.

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 AbstractFigure

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)

Transforms the figure.

Parameters:

tx - The transformation.

See Also:

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

createHandles

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

Description copied from interface: Figure

Creates handles used to manipulate the figure.

Specified by:

createHandles in interface Figure

Overrides:

createHandles in class AbstractFigure

Parameters:

detailLevel - The detail level of the handles. Usually this is 0 for bounding box handles and 1 for point handles. The value -1 is used by the SelectAreaTracker and the HandleTracker to highlight figures, over which the mouse pointer is hovering.

Returns:

a Collection of handles

See Also:

Handle

restoreTransformTo

public void restoreTransformTo(java.lang.Object geometry)

Description copied from interface: Figure

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

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.

See Also:

Figure.transform(AffineTransform)

findConnector

public Connector findConnector(java.awt.geom.Point2D.Double p,
                               ConnectionFigure prototype)

Description copied from class: AbstractFigure

Returns the Figures connector for the specified location. By default a ChopBoxConnector is returned.

Specified by:

findConnector in interface Figure

Overrides:

findConnector in class AbstractFigure

Parameters:

p - the location of the connector.

prototype - The prototype used to create a connection or null if unknown. This allows for specific connectors for different connection figures.

ChopRectangleConnector

findCompatibleConnector

public Connector findCompatibleConnector(Connector c,
                                         boolean isStartConnector)

Description copied from interface: Figure

Gets a compatible connector. If the provided connector is part of this figure, return the connector. If the provided connector is part of another figure, return a connector with the same semantics for this figure. Returns null, if no compatible connector is available.

Specified by:

findCompatibleConnector in interface Figure

Overrides:

findCompatibleConnector in class AbstractFigure

clone

public RoundRectangleFigure clone()

Description copied from interface: Figure

Returns a clone of the figure, with clones of all aggregated figures, such as children and decorators. The cloned figure does not clone the list of FigureListeners from its original.
