public class GTKStyleFactory extends SynthStyleFactory
GTKStyleFactory extends DefaultSynthStyleFactory providing a mapping that mirrors the gtk name space. Styles registered for REGION are mapped to the corresponding gtk class name. Similarly styles registered for CLASS are mapped to the corresponding gtk class name, including the corresponding gtk class hierarchy.

Fields Summary
public static final int
Indicates lookup should be done using the name of the Component. If the name is null this fallsback to the name of the region.
public static final int
Indicates lookup should be done using the region name.
public static final int
Indicates lookup should be done using the class name
private static final Map
Maps from a GTK class name to its super class.
private static final Map
Maps from Region to gtk class.
private List
List of StyleAssociations for WIDGET.
private List
List of StyleAssociations for WIDGET_CLASS.
private List
List of StyleAssociations for CLASS.
private boolean
Labels are special cased. This is set to true when a Style for a label bearing widget is asked for and triggers massaging of the path and class name lookup.
private BakedArrayList
Will hold the label style and label bearing components style. This is used as the key to mergedStyleMap.
private Map
Maps from a List containing the label style and label bearing components style to the merged style.
private SynthStyle
All lookups will at least get this style.
private GTKStyle
Default style for tooltips.
private GTKStyle
Default style for progressbars.
private GTKStyle
Default style for menu items.
private Map
Maps from List to the resolved DefaultSynthStyle.
private BakedArrayList
Used for Style lookup to avoid garbage.
private StringBuffer
StringBuffer used in building paths.
private int[]
Used in matching class styles, will contain the class depth of the matches.
