DESCRIPTION
       The QTextBrowser class provides a rich text browser with hypertext
       navigation.

       This class extends QTextEdit (in read-only mode), adding some
       navigation functionality so that users can follow links in hypertext
       documents. The contents of QTextEdit is set with setText(), but
       QTextBrowser has an additional function, setSource(), which makes it
       possible to set the text to a named document. The name is looked up in
       the text view's mime source factory. If a document name ends with an
       anchor (for example, "#anchor"), the text browser automatically scrolls
       to that position (using scrollToAnchor()). When the user clicks on a
       hyperlink, the browser will call setSource() itself, with the link's
       href value as argument. You can track the current source by connetion
       to the sourceChanged() signal.

       QTextBrowser provides backward() and forward() slots which you can use
       to implement Back and Forward buttons. The home() slot sets the text to
       the very first document displayed. The linkClicked() signal is emitted
       when the user clicks a link.

       By using QTextEdit::setMimeSourceFactory() you can provide your own
       subclass of QMimeSourceFactory. This makes it possible to access data
       from anywhere, for example from a network or from a database. See
       QMimeSourceFactory::data() for details.

       If you intend using the mime factory to read the data directly from the
       file system, you may have to specify the encoding for the file
       extension you are using. For example:

	   mimeSourceFactory()->setExtensionType("qml", "text/utf8");
       This is to ensure that the factory is able to resolve the document
       names.

       QTextBrowser interprets the tags it processes in accordance with the
       default style sheet. Change the style sheet with setStyleSheet(); see
       QStyleSheet for details.

       If you want to provide your users with editable rich text use
       QTextEdit. If you want a text browser without hypertext navigation use
       QTextEdit, and use QTextEdit::setReadOnly() to disable editing. If you
       just need to display a small piece of rich text use QSimpleRichText or
       QLabel.

MEMBER FUNCTION DOCUMENTATION
QTextBrowser::QTextBrowser ( QWidget * parent = 0, const char * name = 0 )
       Constructs an empty QTextBrowser called name, with parent parent.

void QTextBrowser::anchorClicked ( const QString & name, const QString & link
       ) [signal]
       This signal is emitted when the user clicks an anchor. The link is the
       value of the href i.e. the name of the target document. The name is the
       name of the anchor.

       See also linkClicked().

void QTextBrowser::backward () [virtual slot]
       Changes the document displayed to the previous document in the list of
       documents built by navigating links. Does nothing if there is no
       previous document.

       See also forward() and backwardAvailable().

       Example: helpviewer/helpwindow.cpp.

void QTextBrowser::backwardAvailable ( bool available ) [signal]
       This signal is emitted when the availability of backward() changes.
       available is FALSE when the user is at home(); otherwise it is TRUE.

       Example: helpviewer/helpwindow.cpp.

void QTextBrowser::forward () [virtual slot]
       Changes the document displayed to the next document in the list of
       documents built by navigating links. Does nothing if there is no next
       document.

       See also backward() and forwardAvailable().

       Example: helpviewer/helpwindow.cpp.

void QTextBrowser::forwardAvailable ( bool available ) [signal]
       This signal is emitted when the availability of forward() changes.
       available is TRUE after the user navigates backward() and FALSE when
       the user navigates or goes forward().

       Example: helpviewer/helpwindow.cpp.

void QTextBrowser::highlighted ( const QString & link ) [signal]
       This signal is emitted when the user has selected but not activated a
       link in the document. link is the value of the href i.e. the name of
       the target document.

       Example: helpviewer/helpwindow.cpp.

void QTextBrowser::home () [virtual slot]
       Changes the document displayed to be the first document the browser
       displayed.

       Example: helpviewer/helpwindow.cpp.

void QTextBrowser::keyPressEvent ( QKeyEvent * e ) [virtual protected]
       The event e is used to provide the following keyboard shortcuts:
       <center>.nf

       </center>

       Reimplemented from QTextEdit.

void QTextBrowser::linkClicked ( const QString & link ) [signal]
       This signal is emitted when the user clicks a link. The link is the
       value of the href i.e. the name of the target document.

       The link will be the absolute location of the document, based on the
       value of the anchor's href tag and the current context of the document.

       See also anchorClicked() and context().

void QTextBrowser::reload () [virtual slot]
       Reloads the current set source.

void QTextBrowser::setSource ( const QString & name ) [virtual slot]
       Sets the name of the displayed document to name. See the "source"
       property for details.

QString QTextBrowser::source () const
       Returns the name of the displayed document. See the "source" property
       for details.

void QTextBrowser::sourceChanged ( const QString & src ) [signal]
       This signal is emitted when the mime source has changed, src being the
       new source.

       Source changes happen both programmatically when calling setSource(),
       forward(), backword() or home() or when the user clicks on links or
       presses the equivalent key sequences.

       Example: helpviewer/helpwindow.cpp.

   Property Documentation
bool modified
       This property holds whether the contents have been modified.

bool overwriteMode
       This property holds this text browser's overwrite mode.

bool readOnly
       This property holds whether the contents are read only.

QString source
       This property holds the name of the displayed document.

       This is a QString::null if no document is displayed or if the source is
       unknown.

       Setting this property uses the mimeSourceFactory() to lookup the named
       document. It also checks for optional anchors and scrolls the document
       accordingly.

       If the first tag in the document is <qt type=detail>, the document is
       displayed as a popup rather than as new document in the browser window
       itself. Otherwise, the document is displayed normally in the text
       browser with the text set to the contents of the named document with
       setText().

       If you are using the filesystem access capabilities of the mime source
       factory, you must ensure that the factory knows about the encoding of
       specified files; otherwise no data will be available. The default
       factory handles a couple of common file extensions such as *.html and
       *.txt with reasonable defaults. See QMimeSourceFactory::data() for
       details.

       Set this property's value with setSource() and get this property's
       value with source().

int undoDepth
       This property holds this text browser's undo depth.

bool undoRedoEnabled
       This property holds whether undo and redo are enabled.
