Qt-如何检测应用程序是否在GNOME或KDE上运行?

问题描述

我想知道我该怎么做(源)使用Qt.我浏览了文档，但找不到任何方法来检查外部进程是否正在运行.

I was wondering how I could do something like this (source) using Qt. I looked through the documentation but couldn't find any method to check if an external process is running.

if [ "$(pidof ksmserver)" ]; then
   echo "KDE running."
   # KDE-specific stuff here
elif [ "$(pidof gnome-session)" ]; then
   echo "GNOME running."
   # GNOME-specific stuff here
elif [ "$(pidof xfce-mcs-manage)" ]; then
   echo "Xfce running."
   # Xfce-specific stuff here
fi

推荐答案

使用QProcess运行pidof foo，然后检查其stdout?如果这不是您想要的，请搜索/proc/.

Use QProcess to run pidof foo, then check its stdout? If this is not what you want, search /proc/.
