public class JTextPane
extends JEditorPane

Disabled: no SafeJ information.

A text component that can be marked up with attributes that are represented graphically. You can find how-to information and examples of using text panes in Using Text Components, a section in The Java Tutorial.

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 not overridden by attributes set on the paragraph or character run. Components and images may be embedded in the flow of text.

Newlines

For a discussion on how newlines are handled, see DefaultEditorKit.

Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

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 applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder.

Constructor Detail

JTextPane

public JTextPane()

Class is disabled.

Creates a new JTextPane. A new instance of StyledEditorKit is created and set, and the document model set to null.

JTextPane

public JTextPane(StyledDocument doc)

Class is disabled.

Creates a new JTextPane, with a specified document model. A new instance of javax.swing.text.StyledEditorKit is created and set.

Parameters:

doc - the document model

Method Detail

getUIClassID

public String getUIClassID()

Class is disabled.

Returns the class ID for the UI.

Overrides:

getUIClassID in class JEditorPane

Returns:

the string "TextPaneUI"

See Also:

JComponent.getUIClassID(), UIDefaults.getUI(javax.swing.JComponent)

setDocument

public void setDocument(Document doc)

Class is disabled.

Associates the editor with a text document. This must be a StyledDocument.

Overrides:

setDocument in class JTextComponent

Parameters:

doc - the document to display/edit

Throws:

IllegalArgumentException - if doc can't be narrowed to a StyledDocument which is the required type of model for this text component

See Also:

JTextComponent.getDocument()

setStyledDocument

public void setStyledDocument(StyledDocument doc)

Class is disabled.

Associates the editor with a text document. The currently registered factory is used to build a view for the document, which gets displayed by the editor.

Parameters:

doc - the document to display/edit

getStyledDocument

public StyledDocument getStyledDocument()

Class is disabled.

Fetches the model associated with the editor.

Returns:

the model

replaceSelection

public void replaceSelection(String content)

Class is disabled.

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 at the point of insertion. If the document is not editable, beep and return.

Overrides:

replaceSelection in class JEditorPane

Parameters:

content - the content to replace the selection with

insertComponent

public void insertComponent(Component c)

Class is disabled.

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.

The component given is the actual component used by the JTextPane. Since components cannot be a child of more than one container, this method should not be used in situations where the model is shared by text components.

The component is placed relative to the text baseline according to the value returned by Component.getAlignmentY. For Swing components this value can be conveniently set using the method JComponent.setAlignmentY. For example, setting a value of 0.75 will cause 75 percent of the component to be above the baseline, and 25 percent of the component to be below the baseline.

Parameters:

c - the component to insert

insertIcon

public void insertIcon(Icon g)

Class is disabled.

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.

Parameters:

g - the icon to insert

See Also:

Icon

addStyle

public Style addStyle(String nm,
                      Style parent)

Class is disabled.

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)

Class is disabled.

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)

Class is disabled.

Fetches a named non-null style previously added.

Parameters:

nm - the name of the style

Returns:

the Style

setLogicalStyle

public void setLogicalStyle(Style s)

Class is disabled.

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 independent of the element hierarchy in the document.

Parameters:

s - the logical style to assign to the paragraph, or null for no style

getLogicalStyle

public Style getLogicalStyle()

Class is disabled.

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()

Class is disabled.

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)

Class is disabled.

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.

Parameters:

attr - the attributes

replace - if true, then replace the existing attributes first

getParagraphAttributes

public AttributeSet getParagraphAttributes()

Class is disabled.

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)

Class is disabled.

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.

Parameters:

attr - the non-null attributes

replace - if true, replace the existing attributes first

getInputAttributes

public MutableAttributeSet getInputAttributes()

Class is disabled.

Gets the input attributes for the pane.

Returns:

the attributes

getStyledEditorKit

protected final StyledEditorKit getStyledEditorKit()

Class is disabled.

Gets the editor kit.

Returns:

the editor kit

createDefaultEditorKit

protected EditorKit createDefaultEditorKit()

Class is disabled.

Creates the EditorKit to use by default. This is implemented to return javax.swing.text.StyledEditorKit.

Overrides:

createDefaultEditorKit in class JEditorPane

Returns:

the editor kit

setEditorKit

public final void setEditorKit(EditorKit kit)

Class is disabled.

Sets the currently installed kit for handling content. This is the bound property that establishes the content type of the editor.

Overrides:

setEditorKit in class JEditorPane

Parameters:

kit - the desired editor behavior

Throws:

IllegalArgumentException - if kit is not a StyledEditorKit

See Also:

JEditorPane.getEditorKit()

paramString

protected String paramString()

Class is disabled.

Returns a string representation of this JTextPane. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Overrides:

paramString in class JEditorPane

Returns:

a string representation of this JTextPane
