In the following code the commented QPixmap::grab works, but is depreciated. I am trying to get QWidget::grab to work. I am wanting to grab the entire dialog so I am supplying no rect argument, wanting to use the default. I get the following error:

**C:\My Libraries\Programming\CppProj\ptest\printtest\main .cpp:16: error: cannot call member function 'QPixmap QWidget::grab(const QRect&)' without object
QPixmap pm = ArticleDialog::grab();
^
but I thought grab was static? If I replace the class "ArticleDialog" with the instance myWidget, I get the error:

**C:\My Libraries\Programming\CppProj\ptest\printtest\main .cpp:15: error: 'myWidget' is not a class or namespace
QPixmap pm = myWidget::grab();
^

What am I doing wrong?
Qt Code: 
  1. #include "articledialog.h"
  2. #include <QApplication>
  3.  
  4. int main(int argc, char *argv[])
  5. {
  6.     QApplication a(argc, argv);
  7.     ArticleDialog myWidget;
  8.     myWidget.show();
  9.     QPrinter printer;
  10.     QPrintDialog printDialog(&printer);
  11.     if (printDialog.exec() == QDialog::Accepted) {
  12.  
  13.         QPainter p(&printer);
  14.         //QPixmap pm = QPixmap::grabWidget(&myWidget);
  15.         QPixmap pm = ArticleDialog::grab();
  16.         p.drawPixmap(0, 0, pm);
  17.     }
  18.  
  19.     return a.exec();
  20. }
