How to run a system command in Qt?

问题:

I have to run a system command in Qt. but I have to give an argument for that command.

for example opening gedit with a text file. like "gedit /home/oDx/Documents/a.txt"

but the path "/home/oDx/Documents/a.txt" will be in a variable like "docPath". so how can i do it!?

回答1:

QProcess process; process.start("gedit", QStringList() << docPath); 

the same as above

QProcess process; process.start("gedit", QStringList() << "/home/oDx/Documents/a.txt"); 

Also, read this.

回答2:

QProcess::execute() may be helpful:

QProcess::execute("gedit /home/oDx/Documents/a.txt"));
