Constructor Detail

IlvSplineLinkSelection

public IlvSplineLinkSelection(IlvSplineLinkImage obj)

Creates a new spline link selection object.

Parameters:

obj - the selected object

Method Detail

boundingBox

public IlvRect boundingBox(IlvTransformer t)

Returns the bounding box of the object.

Overrides:

boundingBox in class IlvPolyPointsSelection

Parameters:

t - The transformer used to draw the object. If the transformer is null, the bounding box for the identity transformer is returned.

See Also:

IlvGraphic.draw(java.awt.Graphics, ilog.views.IlvTransformer), IlvGraphic.zoomable(), IlvGraphic

draw

public void draw(Graphics dst,
                 IlvTransformer t)

Draws the object.

Overrides:

draw in class IlvHandlesSelection

Parameters:

dst - The destination Graphics.

t - The transformation used to draw the object.

See Also:

IlvGraphic.boundingBox(ilog.views.IlvTransformer), IlvGraphic.zoomable(), IlvGraphic

drawWithoutHandles

public void drawWithoutHandles(Graphics dst,
                               IlvTransformer t)

Draws the object without the handles.

Overrides:

drawWithoutHandles in class IlvHandlesSelection

Parameters:

dst - The destination Graphics.

t - The transformation used to draw the object.

getHandle

public IlvPoint getHandle(int i,
                          IlvTransformer t)

Returns the location of a handle. It calls the getPointAt method of the selected IlvSplineLinkImage object.

Overrides:

getHandle in class IlvPolyPointsSelection

Parameters:

i - the index of the handle.

t - the transformer through which the object is drawn.

beforeLoopAllHandles

protected void beforeLoopAllHandles(IlvTransformer t)

This is called by this class before iterating over all handles and calling getHandle(int, ilog.views.IlvTransformer). Subclasses can override this method to do preparations so that getHandle(int, ilog.views.IlvTransformer) is fast, e.g. fill certain caches that are needed by getHandle(int, ilog.views.IlvTransformer).

Overrides:

beforeLoopAllHandles in class IlvHandlesSelection

Parameters:

t - The transformer to draw this object.

See Also:

afterLoopAllHandles()

afterLoopAllHandles

protected void afterLoopAllHandles()

This is called by this class after iterating over all handles and calling getHandle(int, ilog.views.IlvTransformer). Subclasses can override this method to do cleanup caches that were needed by getHandle(int, ilog.views.IlvTransformer).

Overrides:

afterLoopAllHandles in class IlvHandlesSelection

See Also:

beforeLoopAllHandles(ilog.views.IlvTransformer)

getSplineLink

public IlvSplineLinkImage getSplineLink()

Returns the selected object.

getDefaultInteractor

public String getDefaultInteractor()

Returns the class name of the interactor used to edit polypoints. The interactor is an IlvSplineLinkEdition.

Overrides:

getDefaultInteractor in class IlvLinkImageSelection

See Also:

IlvSplineLinkEdition

SetDefaultInteractor

public static void SetDefaultInteractor(String interactor)

This method allows you to change the default interactor for instances of this class. It is useful to change the interactor used for editing spline objects. Setting it to null will recover the initial interactor.

Parameters:

interactor - The new interactor.

See Also:

getDefaultInteractor()

IsHandlesOnSplineMode

public static boolean IsHandlesOnSplineMode()

Returns whether the handles of the spline link are on the spline. If the handles are outside the spline link, the intersections of the spline tangents are used as position of the handles. If the smoothness of the spline is IlvGraphicUtil.COMPATIBLE_SMOOTHNESS or IlvGraphicUtil.AUTO_SMOOTHNESS, the handles of the spline link are always outside the spline.

SetHandlesOnSplineMode

public static void SetHandlesOnSplineMode(boolean enable)

Sets whether the handles of the spline link are on the spline. If the handles are outside the spline link, the intersections of the spline tangents are used as position of the handles. If the smoothness of the spline is IlvGraphicUtil.COMPATIBLE_SMOOTHNESS or IlvGraphicUtil.AUTO_SMOOTHNESS, the handles of the spline link are always outside the spline. For all other values of the smoothness, the handles are by default on the spline link.

IsShowTangentsMode

public static boolean IsShowTangentsMode()

Returns whether the spline tangents are shown additionally to the selection handles for spline links.

SetShowTangentsMode

public static void SetShowTangentsMode(boolean enable)

Sets whether the tangents are shown additionally to the selection handles for spline links. If the handles are positioned at the intersections of the spline tangents outside the splines links, it is very useful to also show the tangents. Showing the tangents is by default disabled.
