Constructor Detail

StyledEditorKit

public StyledEditorKit()

Creates a new EditorKit used for styled documents.

Method Detail

getInputAttributes

public MutableAttributeSet getInputAttributes()

Gets the input attributes for the pane. When the caret moves and there is no selection, the input attributes are automatically mutated to reflect the character attributes of the current caret location. The styled editing actions use the input attributes to carry out their actions.

Overrides:: getInputAttributes in class DefaultEditorKit

Returns:: the attribute set

getCharacterAttributeRun

public Element getCharacterAttributeRun()

Fetches the element representing the current run of character attributes for the caret.

Returns:: the element

getActions

public Action[] getActions()

Fetches the command list for the editor. This is the list of commands supported by the superclass augmented by the collection of commands defined locally for style operations.

Overrides:: getActions in class DefaultEditorKit

Returns:: the command list

createDefaultDocument

public Document createDefaultDocument()

Creates an uninitialized text storage model that is appropriate for this type of editor.

Overrides:: createDefaultDocument in class DefaultEditorKit

Returns:: the model

install

public void install(JEditorPane c)

Called when the kit is being installed into a JEditorPane.

Overrides:: install in class EditorKit

Parameters:: c - the JEditorPane

deinstall

public void deinstall(JEditorPane c)

Called when the kit is being removed from the JEditorPane. This is used to unregister any listeners that were attached.

Overrides:: deinstall in class EditorKit

Parameters:: c - the JEditorPane

getViewFactory

public ViewFactory getViewFactory()

Fetches a factory that is suitable for producing views of any models that are produced by this kit. This is implemented to return View implementations for the following kinds of elements:

AbstractDocument.ContentElementName
AbstractDocument.ParagraphElementName
AbstractDocument.SectionElementName
StyleConstants.ComponentElementName
StyleConstants.IconElementName

Overrides:: getViewFactory in class DefaultEditorKit

Returns:: the factory

clone

public Object clone()

Creates a copy of the editor kit.

Overrides:: clone in class EditorKit

Returns:: the copy

createInputAttributes

protected void createInputAttributes(Element element,
                                     MutableAttributeSet set)

Copies the key/values in elements AttributeSet into set. This does not copy component, icon, or element names attributes. Subclasses may wish to refine what is and what isn't copied here. But be sure to first remove all the attributes that are in set.

This is called anytime the caret moves over a different location.
