Given a snippet code in QWebpage section, what to put in the main cpp file ?

[Ground]

I am reading QWebPage section in Qt docs.
And I would like to test the snippet code done in this section.
I wanted to try this code but i did not know how to make it completely works.

• I know what to put in the header file : i've put the declaration of the class Thumbnailer.
  And i've add the needed classes :
  #include <QObject>

#include <QtWebKitWidgets/QWebPage>

#include <QWebFrame>

#include <QPainter>

• I've put the rest of the snippet code in a cpp file.

• There is no problem at this step, but the problem* is what to put the main cpp file to make it visible ?*

Here is the link of the QWebPage class reference where the snippet code is :
http://qt-project.org/doc/qt-4.8/qwebpage.html

Thanks in advance for any enligtenment or help about that :)

what do you want to achieve exactly?
The Thumbnailer snippet code just renders a screenshot to an image.
If you want to display this image set it on a QLabel and show the label.
If you want to show the webpage in your application you have to use QWebView widget.
