I can't wrap my mind around printing multiple pages using QPrintPreviewDialog. I searched the forum and the web, nothing helpful came up.

My goal is to print invoices, each page consists of a letter head at the top, followed by the details for the particular customer.

I have no trouble doing this for a single page but I wanted to get a preview with N invoices, each on a separate page.

Here is what I do now:

Qt Code: 
  1. void MainWindow::prepHeader(QTextEdit &t)
  2. {
  3.  
  4.     t.append(QString("a nice letter head"));
  5.     t.append("\n");
  6.  
  7.     t.append(QString("customer info\n"));
  8.  
  9.    t.append("\n\n\n\n\n\n______________________________________________________________\n"); //divider and some spacing
  10.  
  11. }
  12.  
  13.  
  14. void MainWindow::printReport(QTextEdit &pte, QString detail, bool bPreview)
  15. {
  16.  
  17.     QPrintPreviewDialog pvw(printer,this);
  18.  
  19.     if (bPreview)
  20.         connect(&pvw, SIGNAL(paintRequested(QPrinter *)), SLOT(printPreview(QPrinter *)));
  21.  
  22.     prepHeader(pte); //show a company specific letter head
  23.  
  24.     pte.append(detail);
  25.  
  26.  
  27.     if (bPreview)
  28.     {
  29.         pvw.exec();
  30.         pvw.disconnect();
  31.         pte.clear();
  32.     }
  33.     else
  34.         pte.print(printer);
  35.  
  36. }
  37.  
  38. void MainWindow::printPreview(QPrinter *printer)
  39. {
  40.     rpt.print(printer);
  41.  
  42. }
  43.  
  44. void MainWindow::printInvoice()
  45. {
  46.     QString detail;
  47.     QTextStream strm(&detail);
  48.  
  49.  
  50.     strm << "customer details" << endl;
  51.  
  52.     printReport(rpt, detail, true);
  53.  
  54.     detail.clear();
  55. }
