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 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. 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.
