The mission

To display the Print Dialog and print a document.

KDE uses the Qt Printing infrastructure, but adds extra standard features to the Print Dialog, as well as allowing applications to add their own extensions.

The code

 1 #include <QtGui/QPainter>
 2 #include <QtGui/QPrinter>

 4 #include <KdePrintDialog>
 5 #include <KPrintPreview>

17     KAboutData aboutData( "test", "test", "1.0", "test",

20     KApplication app;

22     KAction* m_printPreview = KStandardAction::printPreview(app, SLOT(slotFilePrintPreview()), actionCollection());

24     KHelloWorldPrintDialogWidget optionsWidget;
25 
26     QPrinter printer;
27     printer.setFullPage(true);
28     QPrintDialog *printDialog = KdePrint::createPrintDialog(&printer, QList<QWidget*>() << &yourOptionsWidget, this);
29     printDialog.setWindowTitle(i18n("Print Hello World"));
30     if (printDialog.exec()) {
31         QPainter painter;
32         painter.begin(&printer);
33         painter.drawText(100,100,"Hello World");
34         if (optionsWidget.printMoreText()) {
35         }
36         painter.end(); 
37         // this makes the print job start
38     }
