public abstract class SurfaceZoomRegionList
extends AbstractList<ZoomRegion>

List of zoom regions for use with a SurfacePlot. The number of elements changes according to the current state of the plot, so don't copy it into an array and use that instead.

Constructor Detail

SurfaceZoomRegionList

public SurfaceZoomRegionList(uk.ac.starlink.ttools.plot.SurfacePlot plot)

Constructor.

Parameters:

plot - plot for zooming

Method Detail

requestZoom

protected abstract void requestZoom(double[][] bounds)

Invoked when the user indicates by mouse gestures that a zoomed view is wanted. The elements of the bounds array are 2-element double[] arrays giving (lower, upper) bounds of the range along each axis which is required. A null element indicates that no zooming along that axis is required. Boundary values are in data coordinates.

Parameters:

bounds - zoom request details

size

public int size()

Specified by:

size in interface Collection<ZoomRegion>

Specified by:

size in interface List<ZoomRegion>

Specified by:

size in class AbstractCollection<ZoomRegion>

get

public ZoomRegion get(int index)

Specified by:

get in interface List<ZoomRegion>

Specified by:

get in class AbstractList<ZoomRegion>

reconfigure

public void reconfigure()

Configures this list appropriately for the current state of the plot. Should be called whenever plot geometry changes (including before first use).
