- public class JTextPane
- extends JEditorPane
A text component that can be marked up with attributes that are
represented graphically. This component models paragraphs
that are composed of runs of character level attributes. Each
paragraph may have a logical style attached to it which contains
the default attributes to use if no overriden by attributes set
on the paragraph or character run. Components and images may
be embedded in the flow of text.
For the keyboard keys used by this component in the standard Look and
Feel (L&F) renditions, see the
JTextPane key assignments.
Warning: serialized objects of this class will not be compatible with
future swing releases. The current serialization support is appropriate
for short term storage or RMI between Swing1.0 applications. It will
not be possible to load serialized Swing1.0 objects with future releases
of Swing. The JDK1.2 release of Swing will be the compatibility
baseline for the serialized form of Swing objects.

be narrowed to a StyledDocument which is the
required type of model for this text component
- Overrides:

getStyledDocument
public StyledDocument getStyledDocument()
- Fetches the model associated with the editor.
- Returns:
- the model
replaceSelection
public void replaceSelection(String content)
- Replaces the currently selected content with new content
represented by the given string. If there is no selection
this amounts to an insert of the given text. If there
is no replacement text this amounts to a removal of the
current selection. The replacement text will have the
attributes currently defined for input. If the document is not
editable, beep and return. Then if the document is null, do nothing.
If the content to insert is null or empty, ignore it.
This method is thread safe, although most Swing methods
are not. Please see
Threads
and Swing for more information.
- Parameters:
- content - the content to replace the selection with
- Overrides:
- replaceSelection in class JTextComponent
insertComponent
public void insertComponent(Component c)
- Inserts a component into the document as a replacement
for the currently selected content. If there is no
selection the component is effectively inserted at the
current position of the caret. This is represented in
the associated document as an attribute of one character
of content.
- Parameters:
- c - the component to insert
insertIcon
public void insertIcon(Icon g)
- Inserts an icon into the document as a replacement
for the currently selected content. If there is no
selection the icon is effectively inserted at the
current position of the caret. This is represented in
the associated document as an attribute of one character
of content.
This method is thread safe, although most Swing methods
are not. Please see
Threads
and Swing for more information.
- Parameters:
- g - the icon to insert
- See Also:
- Icon
addStyle
public Style addStyle(String nm,
Style parent)
- Adds a new style into the logical 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). 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 new Style
removeStyle
public void removeStyle(String nm)
- Removes a named non-null style previously added to the document.
- Parameters:
- nm - the name of the style to remove
getStyle
public Style getStyle(String nm)
- Fetches a named non-null style previously added.
- Parameters:
- nm - the name of the style
- Returns:
- the style
setLogicalStyle
public void setLogicalStyle(Style s)
- Sets the logical style to use for the paragraph at the
current caret position. If attributes aren't explicitly set
for character and paragraph attributes they will resolve
through the logical style assigned to the paragraph, which
in term may resolve through some hierarchy completely
independant of the element hierarchy in the document.
This method is thread safe, although most Swing methods
are not. Please see
Threads
and Swing for more information.
- Parameters:
- s - the logical style to assign to the paragraph, or null for
no style
getLogicalStyle
public Style getLogicalStyle()
- Fetches the logical style assigned to the paragraph
represented by the current position of the caret, or null.
- Returns:
- the style
getCharacterAttributes
public AttributeSet getCharacterAttributes()
- Fetches the character attributes in effect at the
current location of the caret, or null.
- Returns:
- the attributes, or null
setCharacterAttributes
public void setCharacterAttributes(AttributeSet attr,
boolean replace)
- Applies the given attributes to character
content. If there is a selection, the attributes
are applied to the selection range. If there
is no selection, the attributes are applied to
the input attribute set which defines the attributes
for any new text that gets inserted.
This method is thread safe, although most Swing methods
are not. Please see
Threads
and Swing for more information.
- Parameters:
- attr - the attributes
- replace - if true, then replace the existing attributes first
getParagraphAttributes
public AttributeSet getParagraphAttributes()
- Fetches the current paragraph attributes in effect
at the location of the caret, or null if none.
- Returns:
- the attributes
setParagraphAttributes
public void setParagraphAttributes(AttributeSet attr,
boolean replace)
- Applies the given attributes to paragraphs. If
there is a selection, the attributes are applied
to the paragraphs that intersect the selection.
if there is no selection, the attributes are applied
to the paragraph at the current caret position.
This method is thread safe, although most Swing methods
are not. Please see
Threads
and Swing for more information.
- Parameters:
- attr - the non-null attributes
- replace - if true, replace the existing attributes first
getInputAttributes
public MutableAttributeSet getInputAttributes()
- Gets the input attributes for the pane.

is implemented to return StyledEditorKit.
- Returns:
- the editor kit
- Overrides:
- createDefaultEditorKit in class JEditorPane
setEditorKit
public final void setEditorKit(EditorKit kit)
- Sets the currently installed kit for handling
content. This is the bound property that
establishes the content type of the editor.
- Parameters:
