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
```
```
  }
```
```
}
```
```
</code>
```
```
 
```
```
=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===
```
```
<code>
```
```
find_package(KDE4 REQUIRED)
```
```
include_directories( ${KDE4_INCLUDES} )
```

kde4_add_executable(printhelloworld printtest.cpp)

target_link_libraries(printhelloworld ${KDE4_KDEPRINT_LIBS})

```
</code>
```

===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
```
```
 
```
```
