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 DOCUMENTATIONQNPWidget::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.
