Your first program shall greet the world with a friendly "hello world", what else ? For that, we will use a KMessageBox. To get more information about the KMessageBox-Class, type "kde: kmessagebox" in your konqueror and it will redirect you to http://developer.kde.org/documentation/library/cvs-api/kdelibs-apidocs/kdeui/html/classKMessageBox.html
#include <QString>
#include <kapplication.h>
#include <kaboutdata.h>
#include <kmessagebox.h>
#include <kcmdlineargs.h>
int main (int argc, char *argv[])
{
KAboutData aboutData( "test", "test",
"1.0", "test", KAboutData::License_GPL,
"(c) 2006" );
KCmdLineArgs::init( argc, argv, &aboutData );
KApplication khello;
KGuiItem kgi( QString( "Hello" ), QString(),
QString( "this is a tooltip" ),
QString( "this is whatsthis" ) );
KMessageBox::questionYesNo( 0, "text", "caption", kgi );
}
If you set up your environment as described in Build/Unstable Version, you can compile this code with
gcc hello.cpp -o hello -I/home/kde-devel/qt-unstable/include/Qt \ -I/home/kde-devel/qt-unstable/include/Qt-Core \ -I/home/kde-devel/qt-unstable/include -I/home/kde-devel/kde/include \ -L/home/kde-devel/kde/lib \ -L/home/kde-devel/qt-unstable/lib -lkdeui -lkdecore -ldl
and then run it with ./hello
