Fields Summary
private static final GTKEngine
BLUEPRINT_ENGINE
There should only ever be one blueprint engine.
private static final BlueprintGraphicsUtils
BLUEPRINT_GRAPHICS
private Info[]
info
Set of Infos used to determine what to paint.
private boolean
iconColorize
Comes from the top level icon_colorize setting in rc files.
private String[]
iconAncestorTypes
Comes from the top level icon_colorize_ancestor_type setting in rec files. These Strings will all be interned by the parser.
private Color

Comes from the top level colorize_color setting in rc files.
Constructors Summary
public BlueprintStyle(DefaultSynthStyle style)
Creates a duplicate of the passed in style.



                 
       
        super(style);
        if (style instanceof BlueprintStyle) {
            BlueprintStyle bpStyle = (BlueprintStyle)style;

            this.iconAncestorTypes = bpStyle.iconAncestorTypes;
            this.colorizeColor = bpStyle.colorizeColor;
        }
public BlueprintStyle(StateInfo[] states, CircularIdentityList classSpecificValues, Font font, int xThickness, int yThickness, GTKStockIconInfo[] icons, Info[] info, boolean iconColorize, String[] iconAncestorTypes, Color colorizeColor)
Creates a BlueprintStyle from the passed in arguments.

        super(states, classSpecificValues, font, xThickness, yThickness, icons);
        this.info = info;
        this.iconColorize = iconColorize;

Methods Summary
public sun.swing.plaf.synth.DefaultSynthStyleaddTo(sun.swing.plaf.synth.DefaultSynthStyle s)

public java.lang.Objectclone()
Creates a copy of the reciever and returns it.

        BlueprintStyle style = (BlueprintStyle)super.clone();
