   +----com.sun.java.swing.text.StyleContext
public class StyleContext
extends Object
implements Serializable
A pool of styles and their associated resources. This class determines the lifetime of a group of resources by being a container that holds caches for various resources such as font and color that get reused by the various style definitions. This can be shared by multiple documents if desired to maximize the sharing of related resources.

Methods

o addStyle 
 public Style addStyle(String nm,
                       Style parent)
Adds a new style into the style hierarchy. Style attributes resolve from bottom up so an attribute specified in a child will override an attribute specified in the parent.

Parameters:
nm - the name of the style (must be unique within the collection of named styles in the document). The name may be null if the style is unnamed, but the caller is responsible for managing the reference returned as an unnamed style can't be fetched by name. An unnamed style may be useful for things like character attribute overrides such as found in a style run.
parent - the parent style. This may be null if unspecified attributes need not be resolved in some other style.
Returns:
the created style
o removeStyle 
 public void removeStyle(String nm)
Removes a named style previously added to the document.

Parameters:
nm - the name of the style to remove
o getStyle 
 public Style getStyle(String nm)

Parameters:
nm - the name of the style
Returns:
the style
o getStyleNames 
 public Enumeration getStyleNames()

Returns:
the list of names
o addChangeListener 
 public void addChangeListener(ChangeListener l)
