DESCRIPTION

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

       A QWidget that is a Web-browser plugin window

       Derive from QNPWidget to create a widget that can be used
       as a 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. Default
       does nothing.


QNPInstance* QNPWidget::instance ()

       Returns the instance for which this widget is the window.


void QNPWidget::leaveInstance () [virtual]

       Called when the mouse leaves the plugin window. Default
       does nothing.


void QNPWidget::setWindow ( bool delold )

       For internal use only.


void QNPWidget::show () [virtual]

       This is needed in order to show plugins correctly on
       Windows. Does nothing on X11.

       Reimplemented for internal reasons; the API is not
       affected.

       Reimplemented from QWidget.


void QNPWidget::unsetWindow ()

       For internal use only.
