Question

I need to execute a system command in Qt and provide an argument for the command.

For example, opening a text file with gedit:

gedit /home/oDx/Documents/a.txt

But the path /home/oDx/Documents/a.txt will be in a variable like docPath.

How can I achieve this?

Answer 1

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

the same as above

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