QNPWidget Class Reference

Detailed 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.

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 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.
