Note

This tutorial seems not to be up to date with current KDE4 development.

Цель

Печать Hello World на принтере.

Версия KDE

Этот код будет работать как для KDE 3 так и для KDE 4.

Код

include <kprinter.h>
include <qpainter.h>
include <kapplication.h>
include <kaboutdata.h>
include <kmessagebox.h>
include <kcmdlineargs.h>

/*
This prints Hello World on your printer

/

int main(int argc, char *argv[])
{

 KAboutData aboutData( "test", "test", "1.0", "test",
     KAboutData::License_GPL, "(c) 2006" );
 KCmdLineArgs::init( argc, argv, &aboutData );
 KApplication app;

 KPrinter job;
 job.setFullPage( true );
 if ( job.setup() )
 {
   QPainter painter;
   painter.begin( &job );
   painter.drawText(100,100,"Hello World");
   painter.end(); 
   // this makes the print job start
 }

}

Explanation

You need a KDE instance to print, because this instance stores your configuration, including your printer configuration. You create one by instanciating the KApplication class.

How to compile

With KDE 4 and CMake

CMakeLists.txt

find_package(KDE4 REQUIRED) include_directories( ${KDE4_INCLUDES} ) kde4_add_executable(printhelloworld printtest.cpp) target_link_libraries(printhelloworld ${KDE4_KDEPRINT_LIBS})

Make and Run

Then do:

cmake .
make
./printhelloworld

With KDE 3

Quite easy:

gcc printtest.cpp -o print -I/usr/lib/qt3/include \
-I/opt/kde3/include -L/opt/kde3/lib \
-L/usr/lib/qt3/lib  -lqt-mt -lkdeprint
