Very Trivial Example

To build the example, you must first build the Qt Netscape Plugin Extension library. Then type make in extensions/nsplugin/examples/trivial/ and copy the resulting trivial.so or nptrivial.dll to the Plugins directory of your WWW browser.

// Qt stuff
#include "qnp.h"
#include <qpainter.h>
#include <qmessagebox.h>

class Trivial : public QNPWidget {
    Q_OBJECT
public:
    void mouseReleaseEvent(QMouseEvent* event)
    {
        QMessageBox::aboutQt(this);
    }

    void paintEvent(QPaintEvent* event)
    {
        QPainter p(this);
        p.setClipRect(event->rect());
        int w = width();
        p.drawRect(rect());
        p.drawText(w/8, 0, w-w/4, height(), AlignCenter|WordBreak, "Trivial!");
    }
};

class TrivialInstance : public QNPInstance {
    Q_OBJECT
public:
    QNPWidget* newWindow()
    {
        return new Trivial;
    }

    void print(QPainter* p)
    {
        p->drawText(0,0,"Hello");
    }
};

class TrivialPlugin : public QNPlugin {
public:
    QNPInstance* newInstance()
    {
        return new TrivialInstance;
    }

    const char* getMIMEDescription() const
    {
        return "trivial/very:xxx:Trivial and useless";
