Class JEditorPane

Implemented Interfaces:
Accessible, ImageObserver, MenuContainer, Scrollable, Serializable
Known Direct Subclasses:
JTextPane
public class JEditorPane
extends JTextComponent
A powerful text editor component that can handle different types of content. The JEditorPane text component is driven by an instance of EditorKit. The editor kit is responsible for providing a default Document implementation, a mechanism for loading and saving documents of its supported content type and providing a set of Actions for manipulating the content. By default the following content types are supported:

getScrollableTracksViewportHeight in interface JTextComponent
Returns:
true when a Viewport should force the height of this component to match the viewport height

getScrollableTracksViewportWidth

type - the content type
classname - the name of the class that is associated with this content type

registerEditorKitForContentType

public static void registerEditorKitForContentType(String type,
                                                   String classname,
                                                   ClassLoader loader)
Establishes the default bindings of type to classname.

setContentType

public final void setContentType(String type)

setEditorKit

public void setEditorKit(EditorKit newValue)

setEditorKitForContentType

public void setEditorKitForContentType(String type,

setPage

public void setPage(String url)
            throws IOException
Sets the current URL being displayed.

setPage

public void setPage(URL page)
            throws IOException
Sets the current URL being displayed.

setText

public void setText(String t)
Sets the text of the JEditorPane. The argument t is expected to be in the format of the current EditorKit. This removes the content of the current document and uses the EditorKit to read in the new text. This allows the EditorKit to handle the String rather than just inserting in plain text.
Overrides:
setText in interface JTextComponent
Parameters:
t - the text to display in this JEditorPane
