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

<syntaxhighlight lang="cpp-qt" line>

  1. include <kprinter.h>
  2. include <qpainter.h>
  3. include <kapplication.h>
  4. include <kaboutdata.h>
  5. include <kmessagebox.h>
  6. 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
 }

}

Разъяснение

Пример печати в KDE необходим, как пример собственной конфигурации, включающей конфигурацию принтера. Создадим его как пример класса KApplication.

Как компилировать

С KDE 4 и CMake

CMakeLists.txt

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

Выполнение сборки и запуск (Make and Run)

Затем делаем:

cmake .
make
./printhelloworld

С KDE 3

Лёгкий способ:

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
