Detailed 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. + +
