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>
  3.  
  4. #include <KdePrintDialog>
  5. #include <KPrintPreview>
  6.  
  7. #include <KApplication>
  8. #include <KAboutData>
  9. #include <KCmdLineArgs>
  10.  
  11. /*
  12. This prints Hello World on your printer
  13. */
  14.  
  15. int main(int argc, char *argv[])
  16. {
  17.     KAboutData aboutData( "test", "test", "1.0", "test",
  18.                           KAboutData::License_GPL, "(c) 2006" );
  19.     KCmdLineArgs::init( argc, argv, &aboutData );
  20.     KApplication app;
  21.  
  22.     KAction* m_printPreview = KStandardAction::printPreview(app, SLOT(slotFilePrintPreview()), actionCollection());
  23.  
  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.     }
  39. }
  40.  
  41. class KHelloWorldPrintDialogWidget : public QWidget
  42. {
  43.     bool printMoreText();
  44.     void setPrintMoreText(bool state);
  45.  
  46.     setWindowTitle(i18n("Your Options Tab Title"));
  47. }
  48.  
  49. void KHelloWorld::slotFilePrintPreview() {
  50.     QPrinter printer;
  51.     KPrintPreview printPreview(&printer);
  52.     yourPrintDrawingRoutine(printer); // draws to the QPrinter
  53.     printPreview.exec();
  54. }

How to compile

CMakeLists.txt

find_package(KDE4 REQUIRED)
include_directories( ${KDE4_INCLUDES} )
kde4_add_executable(printhelloworld printtest.cpp)
target_link_libraries(printhelloworld ${${KDE4_KDECORE_LIBS} ${KDE4_KUTILS_LIBS} ${QT_QTGUI_LIBRARY})

Make and Run

Then do:

cmake .
make
./printhelloworld
