ok thanx a lot. I have just another simple question.
I'm trying to use those selected files in a slot,
those are wav files that are encoded to oggvorbis
files, it works when I select one file but it doesn't
when I select several files, do I need to make a loop
or a foreach or is there a simple trick to do the job?
this is the slot:

   void Kapp::encodeFile()
 {
          KProcess p;
p << "oggenc";
p << kLineEdit1->text();
p.start(KProcess::Block);
}

thanx in advance
