How to run a system command in Qt?

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/a.txt"

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

Answer 1

Strange question man, but

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.
