Hello, this is not an eric4 issue but rather a PySide bug. In the eric4 debugger backend all strings are handled as unicode. That means sys.argv is [u'trypyside.py']. PySide doesn't seem to convert unicode strings to QString. You should report a bug to the PySide people. To reproduce the issue just execute these lines in a Python console. >>> from PySide import QtGui >>> import sys >>> app = QtGui.QApplication([u"pyside.py"]) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: bad argument type for built-in operation Regards, Detlev -- Detlev Offenbach [email protected] _______________________________________________ Eric mailing list [email protected] http://www.riverbankcomputing.com/mailman/listinfo/eric
