public class ODGBezierFigure
extends BezierFigure

ODGBezierFigure is not an actual ODG element, it is used by ODGPathFigure to represent a single BezierPath segment within an ODG path.

ODGBezierFigure

public ODGBezierFigure(boolean isClosed)

Method Detail

createHandles

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

handleMouseClick

public boolean handleMouseClick(java.awt.geom.Point2D.Double p,
                                java.awt.event.MouseEvent evt,
                                DrawingView view)

Description copied from class: BezierFigure

Handles a mouse click.

Specified by:

handleMouseClick in interface Figure

Overrides:

handleMouseClick in class BezierFigure

Parameters:

p - The location of the mouse event.

evt - The mouse event.

view - The drawing view which is the source of the mouse event.

Returns:

Returns true, if the event was consumed.

transform

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

Description copied from interface: Figure

Transforms the shape of the Figure. Transformations using double precision arithmethics are inherently lossy operations. Therefore it is recommended to use getTransformRestoreData() restoreTransformTo() to provide lossless undo/redo functionality.

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

 figure.willChange();
 figure.transform(...);
 figure.changed();
 

Specified by:

transform in interface Figure

Overrides:

transform in class BezierFigure

Parameters:

tx - The transformation.

See Also:

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

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 BezierFigure

flattenTransform

public void flattenTransform()

Transforms all coords of the figure by the current TRANSFORM attribute and then sets the TRANSFORM attribute to null.

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 BezierFigure
