running external applications via QT?

[cruisx]

Hi i am a total beginner in QT 4.5 and was wondering how one can launch an external program or file via QT?

i tried to do system() but the file(cmd.exe) does not show up...although i can see it in task manager. I also tried to run this

QProcess::execute("file path/program.exe");

but i got the same result as above.

any ideas how i can do that? So basically i want to click a button and launch an external application pr Program/file :D help would be appericiated

and the code u use to spawn ... check the QProcess::state () it may in QProcess::NotRunning

or it is emitting void QProcess::started () signal

if all above working fine .. check QProcess::readAllStandardError ()
