NAME

       QNPStream - Stream of data provided to a QNPInstance by the browser

SYNOPSIS

       This class is part of the Qt Netscape Extension.

       #include <qnp.h>

   Public Members
       ~QNPStream ()
       const char * url () const
       uint end () const
       uint lastModified () const
       const char * type () const
       bool seekable () const
       bool okay () const
       bool complete () const
       void requestRead ( int offset, uint length )
       int write ( int len, void * buffer )
       QNPInstance * instance ()
       QNPStream ( QNPInstance * in, const char * mt, _NPStream * st, bool se )

DESCRIPTION

       This class is defined in the Qt Netscape Extension, which can be found in the qt/extensions directory. It is not included in the main Qt
       API.

       The QNPStream class provides a stream of data provided to a QNPInstance by the browser.

       Note that this is neither a QTextStream nor a QDataStream.

       See also QNPInstance::write() and QNPInstance::newStreamCreated().

MEMBER FUNCTION DOCUMENTATION

QNPStream::QNPStream ( QNPInstance * in, const char * mt, _NPStream * st, bool se )
       Creates a stream. Plugins should not call this; they should call QNPInstance::newStream() if they need a stream.

       Takes a QNPInstance in, MIME type mt, a pointer to an _NPStream st and a seekable flag se.

QNPStream::~QNPStream ()
       Destroys the stream.

bool QNPStream::complete () const
       Returns TRUE if the stream has received all the data from the source; otherwise returns FALSE.

uint QNPStream::end () const
       Returns the length of the stream in bytes. The function might return 0 for streams of unknown length.

QNPInstance * QNPStream::instance ()
       Returns the QNPInstance for which this stream was created.

uint QNPStream::lastModified () const
       Returns the time when the source of the stream was last modified.

bool QNPStream::okay () const
       Returns TRUE if no errors have occurred on the stream; otherwise returns FALSE.

void QNPStream::requestRead ( int offset, uint length )
       Requests the section of the stream, of length bytes from offset, be sent to the QNPInstance::write() function of the instance() of this
       stream.

bool QNPStream::seekable () const
       Returns TRUE if the stream is seekable; otherwise returns FALSE.

const char * QNPStream::type () const
       Returns the MIME type of the stream.

const char * QNPStream::url () const
       Returns the URL from which the stream was created.

int QNPStream::write ( int len, void * buffer )
       Writes len bytes from buffer to the stream.

NAME

       QNPWidget - QWidget that is a web browser plugin window

SYNOPSIS

       This class is part of the Qt Netscape Extension.

       #include <qnp.h>

       Inherits QWidget.

   Public Members
       QNPWidget ()
       ~QNPWidget ()
       virtual void enterInstance ()
       virtual void leaveInstance ()
       QNPInstance * instance ()

DESCRIPTION

       This class is defined in the Qt Netscape Extension, which can be found in the qt/extensions directory. It is not included in the main Qt
       API.

       The QNPWidget class provides a QWidget that is a web browser plugin window.

       Derive from QNPWidget to create a widget that can be used as a web browser plugin window, or create one and add child widgets. Instances of
       QNPWidget may only be created when QNPInstance::newWindow() is called by the browser.

       A common way to develop a plugin widget is to develop it as a stand-alone application window, then make it a child of a plugin widget to
       use it as a browser plugin. The technique is:

       class MyPluginWindow : public QNPWidget
       {
	   QWidget* child;
       public:
	   MyPluginWindow()
	   {
	       // Some widget that is normally used as a top-level widget
	       child = new MyIndependentlyDevelopedWidget();
	       // Use the background color of the web page
	       child->setBackgroundColor( backgroundColor() );
	       // Fill the plugin widget
	       child->setGeometry( 0, 0, width(), height() );
	   }
	   void resizeEvent(QResizeEvent*)
	   {
	       // Fill the plugin widget
	       child->resize(size());
	   }
       };

       The default implementation is an empty window.

MEMBER FUNCTION DOCUMENTATION

QNPWidget::QNPWidget ()
       Creates a QNPWidget.

QNPWidget::~QNPWidget ()
       Destroys the window. This will be called by the plugin binding code when the window is no longer required. The web browser will delete
       windows when they leave the page. The bindings will change the QWidget::winId() of the window when the window is resized, but this should
       not affect normal widget behavior.

void QNPWidget::enterInstance () [virtual]
       Called when the mouse enters the plugin window. Does nothing by default.

       Example: grapher/grapher.cpp.

QNPInstance * QNPWidget::instance ()
       Returns the instance for which this widget is the plugin window.

void QNPWidget::leaveInstance () [virtual]
       Called when the mouse leaves the plugin window. Does nothing by default.

       Example: grapher/grapher.cpp.
