Class FontControls

uk.ac.starlink.ast.gui.FontControls

public class FontControls
extends Object

FontControls add a series of controls for selecting from the available families of fonts and assigning a size and style.

This class assumes that it will be laying out its components using the standard GridBagLayouter.

Users of this class should implement the FontChangedListener interface to be informed when the selected font is updated.
