<p>port of http://developer.kde.org/documentation/library/kdeqt/kde3arch/exec.html</p> <p><b>New page</b></p><div>'''KDE Architecture - Starting programs'''<br /> <br /> In KDE there are several ways to start other programs from within<br /> your application. Here is a short summary of your options with reasons why<br /> you should or should not use them.<br /> <br /> ;fork + exec<br /> :You never want to use this unless you have a very good reason why it is impossible to use KProcess.<br /> <br /> ;KProcess<br /> :You want to use [http://api.kde.org/3.5-api/kdelibs-apidocs/kdecore/html/classKProcess.html KProcess] class if you need to start a new process which needs to be a child of your process, e.g. because you want to catch stdout/stderr or need to send it data via stdin. You should never use this to start other KDE applications unless your application is called kgdb :-) If you need to send/receive text like data to/from the process, you are probably better off with KProcIO.<br /> <br /> ;KProcIO<br /> :Like KProcess. Unlike KProcess, the [http://api.kde.org/3.5-api/kdelibs-apidocs/kdecore/html/classKProcIO.html KProcIO] class actually makes it easy to send data to and receive data from the process.<br /> <br /> ;startServiceByDesktopPath<br /> :Preferred way to launch desktop (KDE/Gnome/X) applications or KDE services. The application/service must have a .desktop file. It will make use of KDEinit for increased startup performance and lower memory usage. These benefits only apply to applications available as KDEinit loadable module (KLM).<br /> <br /> ;KRun<br /> :Generic way to open documents/applications/shell commands. Uses startServiceBy.... where applicable. Offers the additional benefit of startup-notification.&lt;br/&gt; [http://api.kde.org/3.5-api/kdelibs-apidocs/kio/kio/html/classKRun.html KRun] can start any application, from the binary or the desktop file, it will determine the mimetype of a file before running the preferred handler for it, and it can also start shell commands. This makes KRun the recommended way to run another program in KDE.<br /> <br /> <br /> ''Initial Author:'' [mailto:bastian@kde.org Waldo Bastian]</div>
