#include <QApplication>
#include <QDebug>
#include <QFontDialog>

class QFontDialogTester : public QWidget
{
public:
  void onFont()
  {
    bool ok;
    QFont font = QFontDialog::getFont(
                    &ok,
                    QFont( "Arial", 18 ),
                    this,
                    tr("Pick a font") );
    if( ok )
    {
      qDebug() << "font           : " << font;
      qDebug() << "font weight    : " << font.weight();
      qDebug() << "font family    : " << font.family();
      qDebug() << "font style     : " << font.style();  //  StyleNormal = 0, StyleItalic = 1, StyleOblique = 2
      qDebug() << "font pointSize : " << font.pointSize();
    }
  }

};

int main( int argc, char **argv )
{
  QApplication app( argc, argv );
  QFontDialogTester font_test;
  font_test.onFont();
  return 0;
}
