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.
