Code review comment for lp:~phill-ridout/openlp/overwrite

 if ret == QtGui.QMessageBox.Yes:
     return True
 elif ret == QtGui.QMessageBox.No:
     return False

Can be replaced with:

 return ret == QtGui.QMessageBox.Yes

What changed between lines 29 and 30? Please make sure you're using UNIX/Linux line endings.

There's actually no need for brackets around the returned params on line 39.

Please use words_separated_by_underscores, as per PEP8. Wordsthatarechainedtogetherarehardtoreadandunderstand.

You also don't need brackets around all the things you are returning.
