Class ShapeListener

java.lang.Object

          util.PropertyBundles
              jfits.ShapeListener

All Implemented Interfaces:

PropertyChangeListener, Cloneable, EventListener, Initializable, LocalizedSupplying, PropertySupplying, ResourceSupplying

Direct Known Subclasses:

ShapePrincipal, ShapeStatistic

public abstract class ShapeListener
extends PropertyBundles
implements PropertyChangeListener

A listener that is notified when a ShapeDraw object is added to a FitsCanvas. It prepares the original FitsShape underlying the modified ShapeDraw object to reflect a proper size and position in CCD pixel space. Depending on the nature of the property change, one of the addFitsShape(jfits.FitsShape, java.awt.geom.AffineTransform), selectFitsShape(jfits.FitsShape, java.awt.geom.AffineTransform), or deleteFitsShape(jfits.FitsShape, java.awt.geom.AffineTransform) methods is called, which are all empty methods in the default implementation. Subclasses should override the method(s) they are interested in and, e.g., display an ADU graph.

Note that all formerly mentioned methods are called from within the event queue, so start a new thread, if the method takes too long.

Method Detail

propertyChange

public void propertyChange(PropertyChangeEvent pce)

The fits canvas calls that method, if a shape cursor adds, selects, or deletes a shapedraw object. In particular interest are events on fits canvas, where we can grab the underlying ADUs to process them further in either of addFitsShape(jfits.FitsShape, java.awt.geom.AffineTransform), selectFitsShape(jfits.FitsShape, java.awt.geom.AffineTransform), or the deleteFitsShape(jfits.FitsShape, java.awt.geom.AffineTransform) methods.

Specified by:

propertyChange in interface PropertyChangeListener

applyFitsShape

private void applyFitsShape(JFitsCanvas fcan,
                            String what,
                            FitsShape apert,
                            AffineTransform b)

Applies the fits canvas to the finally restored fits shape, under the desired transformation. Null ought to be a valid transform.

addFitsShape

protected void addFitsShape(FitsShape f,
                            AffineTransform adu)

Empty, override if you are interested in receiving add events. The correct HDU has already been registered, continue by querying the ADUs with the provided transform

selectFitsShape

protected void selectFitsShape(FitsShape f,
                               AffineTransform adu)

Empty, override if you are interested in receiving select events. The correct HDU has already been registered, continue by querying the ADUs with the provided transform

deleteFitsShape

protected void deleteFitsShape(FitsShape f,
                               AffineTransform adu)

Empty, override if you are interested in receiving delete events. The correct HDU has already been registered, continue by querying the ADUs with the provided transform
