Class LineControls

java.lang.Object

uk.ac.starlink.ast.gui.LineControls

public class LineControls
extends Object

LineControls add a series of controls for showing and changing the display properties of any drawn lines (the thickness, style and colour).

This class assumes that it will be laying out its components as part of a GridBagLayouter scheme. It adds the controls in a set of incrementing rows, starting from the current GridBagLayouter position.

Users of this class should register a ChangeListener to be informed when the line properties are changed (get the actual value using the get methods).
