Greetings everyone!
I'm having a trouble with printing via Qt.
What I want - is to print the viewable content of MainWindow using QPrint. I have printed test sheets using this code:
Qt Code: 
  1. void MainWindow::setup_print(void)
  2. {
  3.     dialog = new QPrintDialog(&printer, this);
  4.     if (dialog->exec() == QDialog::Accepted)
  5.     {
  6.         QPainter painter( &printer );
  7.  
  8.         painter.setPen( Qt::black );
  9.  
  10.         for( int page=0; page<5; page++ )
  11.         {
  12.             painter.drawRect( printer.pageRect() );
  13.             painter.drawLine( printer.pageRect().topLeft(), printer.pageRect().bottomRight() );
  14.             painter.drawLine( printer.pageRect().topRight(), printer.pageRect().bottomLeft() );
  15.             painter.drawRect(this->contentsRect() );
  16.             QRectF textArea(
  17.                 printer.pageRect().left()  +printer.resolution() * 0.5,
  18.                 printer.pageRect().top()   +printer.resolution() * 0.5,
  19.                 printer.pageRect().width() -printer.resolution() * 1.0,
  20.                 printer.pageRect().height()-printer.resolution() * 1.5 );
  21.  
  22.             painter.drawRect( textArea );
  23.  
  24.             painter.drawText( textArea, Qt::AlignTop | Qt::AlignLeft, QString( "Page %1" ).arg( page+1 ) );
  25.  
  26.             if( page != 4 )
  27.  
  28.               printer.newPage();
  29.         }
  30.     }
  31. }
To copy to clipboard, switch view to plain text mode 
the "printer" object is mainwindow class member.
The problem is that I have no idea how to get the content of mainwindow be represented as a QPainter object.
Can anyone help me with this please?
