Constructor Detail

IlvChartLocalZoomInteractor

public IlvChartLocalZoomInteractor()

Creates a new IlvChartLocalZoomInteractor object with the zoom in interaction associated with the BUTTON1 mouse button and the zoom out interaction set on the BUTTON1+SHIFT mouse event and linked to the first Y-axis.

IlvChartLocalZoomInteractor

public IlvChartLocalZoomInteractor(int yAxisIndex,
                                   int zoomInEventMask,
                                   int zoomOutEventMask)

Creates a new IlvChartLocalZoomInteractor.

Parameters:

yAxisIndex - The Y-axis index.

zoomInEventMask - The event mask used to zoom in.

zoomOutEventMask - The event mask used to zoom out.

Method Detail

getLocalizedName

public static String getLocalizedName(Locale locale)

Returns a localized name for this interactor class.

Since:

JViews 7.5

getXTransformer

protected IlvLocalZoomAxisTransformer getXTransformer()

Returns the IlvLocalZoomAxisTransformer associated with the X-axis. Returns null whether there is no transformer or it is not a local zoom.

getYTransformer

protected IlvLocalZoomAxisTransformer getYTransformer()

Returns the IlvLocalZoomAxisTransformer associated with the Y-axis. Returns null whether there is no transformer or it is not a local zoom.

isValidStartPoint

protected boolean isValidStartPoint(double x,
                                    double y)

Returns true if the given point is in the local zoomed area.

Overrides:

isValidStartPoint in class IlvChartZoomInteractor

validate

protected void validate(IlvDataWindow zoomDataWindow)

Called to validate the current zoomed area. Overridden to clip the data window given as parameter to the local zoom transformers areas.

Overrides:

validate in class IlvChartZoomInteractor

doIt

protected void doIt()

Called when the action ends. The default implementation computes the new zoom factor according to the dragged data window.

Overrides:

doIt in class IlvChartZoomInteractor

See Also:

IlvChartZoomInteractor.getDraggedWindow()

has3DSupport

public boolean has3DSupport()

Indicates whether the interactor can be used with a 3D chart.

Specified by:

has3DSupport in interface IlvChart3DSupport

Overrides:

has3DSupport in class IlvChartZoomInteractor

Returns:

false.

Since:

JViews 5.5

endOperation

protected void endOperation(MouseEvent event)

Called when the interaction ends. You may override this method to add your own initialization code.

Overrides:

endOperation in class IlvChartZoomInteractor

Parameters:

event - The event that ends the interaction.

abort

protected void abort()

Called when the interaction has been aborted. You may override this method to add your own initialization code.

Overrides:

abort in class IlvChartZoomInteractor
