Class SurfaceZoomRegionList

  • All Implemented Interfaces:
    java.lang.Iterable<ZoomRegion>, java.util.Collection<ZoomRegion>, java.util.List<ZoomRegion>
    public abstract class SurfaceZoomRegionList
extends java.util.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.

        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 java.util.Collection<ZoomRegion>
        Specified by:
        size in interface java.util.List<ZoomRegion>
        Specified by:
        size in class java.util.AbstractCollection<ZoomRegion>

      • get

        public ZoomRegion get​(int index)
        Specified by:
        get in interface java.util.List<ZoomRegion>
        Specified by:
        get in class java.util.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).
