Hi,

I'm having some troubles with printing under Windows. I'm setting a qprinter via a qprintdialog and pass the qprinter to a method which creates a qpainter on the qprinter. Essentially:
Qt Code: 
  1. void functionA()
  2. {
  3.   QPrinter printer;
  4.   printer.setColorMode( QPrinter::Color );
  5.   printer.setOrientation( QPrinter::Landscape );
  6.   QPrintDialog printDialog( &printer, this );
  7.   if ( printDialog.exec() != QDialog::Accepted )
  8.     return;
  9.   print( printer );
  10. }
  11.  
  12. void print( QPrinter &printer )
  13. {
  14.   printer.setOutputFormat( QPrinter::PdfFormat );
  15.   printer.setPaperSize( _gttPrintDialog->pdfPaperSize() );
  16.   printer.setFullPage( true );
  17.   QPainter painter( &printer );
  18.   // ...work with the painter...
  19. }
To copy to clipboard, switch view to plain text mode 

This results in no printout under Windows but under Linux there are no problems. Additionally, as soon as I define the printer inside print(...) everything works like a charm. Sadly, this is no permanent option and it seems like QPrinter can neither be passed by value nor can be copied to a local variable.
What's the reason for this behavior under Windows and is there any solution simpler than passing qpainters instead of qprinters and restructer the whole call tree of paint(...)?
