public class Path
extends Shape

The Path class represents a simple shape and provides facilities required for basic construction and management of a geometric path. Example:

import javafx.scene.shape.*;

Path path = new Path();

MoveTo moveTo = new MoveTo();
moveTo.setX(0.0f);
moveTo.setY(0.0f);

HLineTo hLineTo = new HLineTo();
hLineTo.setX(70.0f);

QuadCurveTo quadCurveTo = new QuadCurveTo();
quadCurveTo.setX(120.0f);
quadCurveTo.setY(60.0f);
quadCurveTo.setControlX(100.0f);
quadCurveTo.setControlY(0.0f);

LineTo lineTo = new LineTo();
lineTo.setX(175.0f);
lineTo.setY(55.0f);

ArcTo arcTo = new ArcTo();
arcTo.setX(50.0f);
arcTo.setY(50.0f);
arcTo.setRadiusX(50.0f);
arcTo.setRadiusY(50.0f);

path.getElements().add(moveTo);
path.getElements().add(hLineTo);
path.getElements().add(quadCurveTo);
path.getElements().add(lineTo);
path.getElements().add(arcTo);

impl_isFirstPathElementValid

private boolean impl_isFirstPathElementValid()

impl_updatePeer

@Deprecated
public void impl_updatePeer()

Deprecated. This is an internal API that is not intended for use and will be removed in the next version

Description copied from class: Node

This function is called during synchronization to update the state of the PG Node from the FX Node. Subclasses of Node should override this method and must call super.impl_updatePeer()

impl_updatePeer in class Shape

impl_cssGetFillInitialValue

@Deprecated
protected Paint impl_cssGetFillInitialValue()

Deprecated. This is an internal API that is not intended for use and will be removed in the next version

impl_cssGetStrokeInitialValue

@Deprecated
protected Paint impl_cssGetStrokeInitialValue()

Deprecated. This is an internal API that is not intended for use and will be removed in the next version

toString

public java.lang.String toString()

Returns a string representation of this Path object.

Overrides:

toString in class Node

Returns:

a string representation of this Path object.
