Type Parameters:

N - The type of visual used by this handle. Needs to be a sub-type of Node.

All Implemented Interfaces:

java.lang.Comparable<AbstractFXSegmentHandlePart<? extends javafx.scene.Node>>, IActivatable, IAdaptable, IDisposable, IPropertyChangeNotifier, IHandlePart<javafx.scene.Node,N>, IVisualPart<javafx.scene.Node,N>

Direct Known Subclasses:

FXCircleSegmentHandlePart, FXRectangleSegmentHandlePart

public abstract class AbstractFXSegmentHandlePart<N extends javafx.scene.Node>
extends AbstractFXHandlePart<N>
implements java.lang.Comparable<AbstractFXSegmentHandlePart<? extends javafx.scene.Node>>

An AbstractFXSegmentHandlePart is bound to a segment of a poly-bezier handle geometry, represented by an array of BezierCurves. The segmentIndex of the AbstractFXSegmentHandlePart identifies that segment (0, 1, 2, ...). The segmentParameter specifies the position of this handle part on the segment (0 = start, 0.5 = mid, 1 = end).

Constructor Detail

AbstractFXSegmentHandlePart

public AbstractFXSegmentHandlePart(com.google.inject.Provider<BezierCurve[]> segmentsProvider,
                                   int segmentIndex,
                                   double segmentParameter)

Method Detail

compareTo

public int compareTo(AbstractFXSegmentHandlePart<? extends javafx.scene.Node> o)

Specified by:

compareTo in interface java.lang.Comparable<AbstractFXSegmentHandlePart<? extends javafx.scene.Node>>

doRefreshVisual

public void doRefreshVisual(N visual)

Specified by:

doRefreshVisual in class AbstractVisualPart<javafx.scene.Node,N extends javafx.scene.Node>

getPosition

protected Point getPosition(BezierCurve segment)

getSegmentCount

public int getSegmentCount()

getSegmentIndex

public int getSegmentIndex()

The segmentIndex specifies the segment of the IGeometry provided by the handle geometry provider on which this selection handle part is positioned. For a shape geometry, segments are determined by the IShape.getOutlineSegments() method. For a curve geometry, segments are determined by the ICurve.toBezier() method. The exact position on the segment is specified by the segmentParameter.

Returns:

segmentIndex

getSegmentParameter

public double getSegmentParameter()

The segmentParameter is a value between 0 and 1. It determines the final point on the segment which this selection handle part belongs to.

Returns:

segmentParameter

getSegmentsInScene

protected BezierCurve[] getSegmentsInScene()

setSegmentIndex

public void setSegmentIndex(int segmentIndex)

Sets the segment index and refreshes the visual.

Parameters:

segmentIndex - The segment index to set.

See Also:

getSegmentIndex()

setSegmentParameter

public void setSegmentParameter(double segmentParameter)

Sets the segment parameter and refreshes the visual.

Parameters:

segmentParameter - The segment parameter to set.

See Also:

getSegmentParameter()

updateLocation

protected void updateLocation(N visual)
