Question

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/

Answer 1

QProcess::execute() may be helpful:

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

Answer 2

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

the same as above

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