   Public Members

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.
