Constructor Detail

JEditorPane

public JEditorPane()

Creates a new JEditorPane. The document model is set to null.

JEditorPane

public JEditorPane(URL initialPage)
            throws IOException

Creates a JEditorPane based on a specified URL for input.

Parameters:

initialPage - the URL

Throws:

IOException - if the URL is null or cannot be accessed

JEditorPane

public JEditorPane(String url)
            throws IOException

Creates a JEditorPane based on a string containing a URL specification.

Parameters:

url - the URL

Throws:

IOException - if the URL is null or cannot be accessed

JEditorPane

public JEditorPane(String type,
                   String text)

Creates a JEditorPane that has been initialized to the given text. This is a convenience constructor that calls the setContentType and setText methods.

Parameters:

type - mime type of the given text

text - the text to initialize with

Throws:

NullPointerException - if the type parameter is null

addHyperlinkListener

public void addHyperlinkListener(HyperlinkListener listener)

Adds a hyperlink listener for notification of any changes, for example when a link is selected and entered.

Parameters:

listener - the listener

removeHyperlinkListener

public void removeHyperlinkListener(HyperlinkListener listener)

Removes a hyperlink listener.

Parameters:

listener - the listener

getHyperlinkListeners

public HyperlinkListener[] getHyperlinkListeners()

Returns an array of all the HyperLinkListeners added to this JEditorPane with addHyperlinkListener().

Returns:

all of the HyperLinkListeners added or an empty array if no listeners have been added

Since:

1.4

fireHyperlinkUpdate

public void fireHyperlinkUpdate(HyperlinkEvent e)

Notifies all listeners that have registered interest for notification on this event type. This is normally called by the currently installed EditorKit if a content type that supports hyperlinks is currently active and there was activity with a link. The listener list is processed last to first.

Parameters:

e - the event

See Also:

EventListenerList

setPage

public void setPage(URL page)
             throws IOException

Sets the current URL being displayed. The content type of the pane is set, and if the editor kit for the pane is non-null, then a new default document is created and the URL is read into it. If the URL contains and reference location, the location will be scrolled to by calling the scrollToReference method. If the desired URL is not the one currently being displayed, the getStream method is called to give subclasses control over the stream provided.

This may load either synchronously or asynchronously depending upon the document returned by the EditorKit. If the Document is of type AbstractDocument and has a value returned by AbstractDocument.getAsynchronousLoadPriority that is greater than or equal to zero, the page will be loaded on a separate thread using that priority.

If the document is loaded synchronously, it will be filled in with the stream prior to being installed into the editor with a call to setDocument, which is bound and will fire a property change event. If an IOException is thrown the partially loaded document will be discarded and neither the document or page property change events will be fired. If the document is successfully loaded and installed, a view will be built for it by the UI which will then be scrolled if necessary, and then the page property change event will be fired.

If the document is loaded asynchronously, the document will be installed into the editor immediately using a call to setDocument which will fire a document property change event, then a thread will be created which will begin doing the actual loading. In this case, the page property change event will not be fired by the call to this method directly, but rather will be fired when the thread doing the loading has finished. It will also be fired on the event-dispatch thread. Since the calling thread can not throw an IOException in the event of failure on the other thread, the page property change event will be fired when the other thread is done whether the load was successful or not.

Parameters:

page - the URL of the page

Throws:

IOException - for a null or invalid page specification, or exception from the stream being read

See Also:

getPage()

read

public void read(InputStream in,
                 Object desc)
          throws IOException

This method initializes from a stream. If the kit is set to be of type HTMLEditorKit, and the desc parameter is an HTMLDocument, then it invokes the HTMLEditorKit to initiate the read. Otherwise it calls the superclass method which loads the model as plain text.

Parameters:

in - the stream from which to read

desc - an object describing the stream

Throws:

IOException - as thrown by the stream being used to initialize

See Also:

JTextComponent.read(java.io.Reader, java.lang.Object), JTextComponent.setDocument(javax.swing.text.Document)

getStream

protected InputStream getStream(URL page)
                         throws IOException

Fetches a stream for the given URL, which is about to be loaded by the setPage method. By default, this simply opens the URL and returns the stream. This can be reimplemented to do useful things like fetch the stream from a cache, monitor the progress of the stream, etc.

This method is expected to have the the side effect of establishing the content type, and therefore setting the appropriate EditorKit to use for loading the stream.

If this the stream was an http connection, redirects will be followed and the resulting URL will be set as the Document.StreamDescriptionProperty so that relative URL's can be properly resolved.

Parameters:

page - the URL of the page

Throws:

IOException

scrollToReference

public void scrollToReference(String reference)

Scrolls the view to the given reference location (that is, the value returned by the UL.getRef method for the URL being displayed). By default, this method only knows how to locate a reference in an HTMLDocument. The implementation calls the scrollRectToVisible method to accomplish the actual scrolling. If scrolling to a reference location is needed for document types other than HTML, this method should be reimplemented. This method will have no effect if the component is not visible.

Parameters:

reference - the named location to scroll to

getPage

public URL getPage()

Gets the current URL being displayed. If a URL was not specified in the creation of the document, this will return null, and relative URL's will not be resolved.

Returns:

the URL, or null if none

setPage

public void setPage(String url)
             throws IOException

Sets the current URL being displayed.

Parameters:

url - the URL for display

Throws:

IOException - for a null or invalid URL specification

getUIClassID

public String getUIClassID()

Gets the class ID for the UI.

Overrides:

getUIClassID in class JComponent

Returns:

the string "EditorPaneUI"

See Also:

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

createDefaultEditorKit

protected EditorKit createDefaultEditorKit()

Creates the default editor kit (PlainEditorKit) for when the component is first created.

Returns:

the editor kit

getEditorKit

public EditorKit getEditorKit()

Fetches the currently installed kit for handling content. createDefaultEditorKit is called to set up a default if necessary.

Returns:

the editor kit

getContentType

public final String getContentType()

Gets the type of content that this editor is currently set to deal with. This is defined to be the type associated with the currently installed EditorKit.

Returns:

the content type, null if no editor kit set

setContentType

public final void setContentType(String type)

Sets the type of content that this editor handles. This calls getEditorKitForContentType, and then setEditorKit if an editor kit can be successfully located. This is mostly convenience method that can be used as an alternative to calling setEditorKit directly.

If there is a charset definition specified as a parameter of the content type specification, it will be used when loading input streams using the associated EditorKit. For example if the type is specified as text/html; charset=EUC-JP the content will be loaded using the EditorKit registered for text/html and the Reader provided to the EditorKit to load unicode into the document will use the EUC-JP charset for translating to unicode. If the type is not recognized, the content will be loaded using the EditorKit registered for plain text, text/plain.

Parameters:

type - the non-null mime type for the content editing support

Throws:

NullPointerException - if the type parameter is null

See Also:

getContentType()

setEditorKit

public 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. Any old kit is first deinstalled, then if kit is non-null, the new kit is installed, and a default document created for it. A PropertyChange event ("editorKit") is always fired when setEditorKit is called.

NOTE: This has the side effect of changing the model, because the EditorKit is the source of how a particular type of content is modeled. This method will cause setDocument to be called on behalf of the caller to ensure integrity of the internal state.

Parameters:

kit - the desired editor behavior

See Also:

getEditorKit()

getEditorKitForContentType

public EditorKit getEditorKitForContentType(String type)

Fetches the editor kit to use for the given type of content. This is called when a type is requested that doesn't match the currently installed type. If the component doesn't have an EditorKit registered for the given type, it will try to create an EditorKit from the default EditorKit registry. If that fails, a PlainEditorKit is used on the assumption that all text documents can be represented as plain text.

This method can be reimplemented to use some other kind of type registry. This can be reimplemented to use the Java Activation Framework, for example.

Parameters:

type - the non-null content type

Returns:

the editor kit

setEditorKitForContentType

public void setEditorKitForContentType(String type,
                                       EditorKit k)

Directly sets the editor kit to use for the given type. A look-and-feel implementation might use this in conjunction with createEditorKitForContentType to install handlers for content types with a look-and-feel bias.

Parameters:

type - the non-null content type

k - the editor kit to be set

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 (i.e. the content string is empty or null) this amounts to a removal of the current selection. The replacement text will have the attributes currently defined for input. If the component is not editable, beep and return.

This method is thread safe, although most Swing methods are not. Please see Threads and Swing for more information.

Overrides:

replaceSelection in class JTextComponent

Parameters:

content - the content to replace the selection with. This value can be null

createEditorKitForContentType

public static EditorKit createEditorKitForContentType(String type)

Creates a handler for the given type from the default registry of editor kits. The registry is created if necessary. If the registered class has not yet been loaded, an attempt is made to dynamically load the prototype of the kit for the given type. If the type was registered with a ClassLoader, that ClassLoader will be used to load the prototype. If there was no registered ClassLoader, Class.forName will be used to load the prototype.

Once a prototype EditorKit instance is successfully located, it is cloned and the clone is returned.

Parameters:

type - the content type

Returns:

the editor kit, or null if there is nothing registered for the given type

registerEditorKitForContentType

public static void registerEditorKitForContentType(String type,
                                                   String classname)

Establishes the default bindings of type to classname. The class will be dynamically loaded later when actually needed, and can be safely changed before attempted uses to avoid loading unwanted classes. The prototype EditorKit will be loaded with Class.forName when registered with this method.

Parameters:

type - the non-null content type

classname - the class to load later

registerEditorKitForContentType

public static void registerEditorKitForContentType(String type,
                                                   String classname,
                                                   ClassLoader loader)

Establishes the default bindings of type to classname. The class will be dynamically loaded later when actually needed using the given ClassLoader, and can be safely changed before attempted uses to avoid loading unwanted classes.

Parameters:

type - the non-null content type

classname - the class to load later

loader - the ClassLoader to use to load the name

getEditorKitClassNameForContentType

public static String getEditorKitClassNameForContentType(String type)

Returns the currently registered EditorKit class name for the type type.

Parameters:

type - the non-null content type

Since:

1.3

getPreferredSize

public Dimension getPreferredSize()

Returns the preferred size for the JEditorPane. The preferred size for JEditorPane is slightly altered from the preferred size of the superclass. If the size of the viewport has become smaller than the minimum size of the component, the scrollable definition for tracking width or height will turn to false. The default viewport layout will give the preferred size, and that is not desired in the case where the scrollable is tracking. In that case the normal preferred size is adjusted to the minimum size. This allows things like HTML tables to shrink down to their minimum size and then be laid out at their minimum size, refusing to shrink any further.

Overrides:

getPreferredSize in class JComponent

Returns:

a Dimension containing the preferred size

See Also:

JComponent.setPreferredSize(java.awt.Dimension), ComponentUI

setText

public void setText(String t)

Sets the text of this TextComponent to the specified content, which is expected to be in the format of the content type of this editor. For example, if the type is set to text/html the string should be specified in terms of HTML.

This is implemented to remove the contents of the current document, and replace them by parsing the given string using the current EditorKit. This gives the semantics of the superclass by not changing out the model, while supporting the content type currently set on this component. The assumption is that the previous content is relatively small, and that the previous content doesn't have side effects. Both of those assumptions can be violated and cause undesirable results. To avoid this, create a new document, getEditorKit().createDefaultDocument(), and replace the existing Document with the new one. You are then assured the previous Document won't have any lingering state.

1. Leaving the existing model in place means that the old view will be torn down, and a new view created, where replacing the document would avoid the tear down of the old view.
2. Some formats (such as HTML) can install things into the document that can influence future contents. HTML can have style information embedded that would influence the next content installed unexpectedly.

An alternative way to load this component with a string would be to create a StringReader and call the read method. In this case the model would be replaced after it was initialized with the contents of the string.

This method is thread safe, although most Swing methods are not. Please see Threads and Swing for more information.

Overrides:

setText in class JTextComponent

Parameters:

t - the new text to be set

See Also:

getText()

getText

public String getText()
