[Interest] Qt 5 Printer-specific options in QPrintDialog (Linux, CUPS)

[Michael Weghorn]

This is the source code I have used for testing on both, Qt 4 and Qt 5:

#include <QApplication>
#include <QPrinter>
#include <QPrintDialog>
#include <QPainter>

int main( int argc, char **argv )
{
  QApplication app( argc, argv );


  QPrinter printer;
  QPrintDialog dlg( &printer );
  if( dlg.exec() == QDialog::Accepted )
  {
    QPainter painter( &printer );

  }

  return 0;
}
