ok i may be being thick here but i have a problem.
i subclassed QStandardItemModel for my app, and have set up a model with 4 columns. when i read a list of items from a file it adds the rows in arraying the items in the correct order. that is File, Title, Artist, Album. now when i double click on the treeview it calls the following code

Qt Code: 
  1. void myTunes::treeDclick(QModelIndex index)
  2. {
  3.     QString str(model->fileForIndex(index));
  4.     Phonon::MediaSource src(str);
  5.     mediaObject->stop();
  6.     mediaObject->setCurrentSource(src);
  7.     mediaObject->play();
  8. }
To copy to clipboard, switch view to plain text mode 

Qt Code: 
  1. QString mediaLibrary::fileForIndex(QModelIndex index)
  2. {
  3.     int i;
  4.     i = index.row();
  5.     return QString(item(i,0)->text());
  6. }
To copy to clipboard, switch view to plain text mode 

when compiled the programme runs fine untill the double click event when the code
Qt Code: 
  1. return QString(item(i,0)->text());
To copy to clipboard, switch view to plain text mode 
creates an error and the debugger halts the programme execution. so my question is why??? and how do i get around it???

as there are no errors shown i cant post them. any help would be very much appreciated.
