For selecting an item in the list widget and retrieving an item see QListWidget::setCurrentItem() and QListWidget::currentItem(): http://doc.trolltech.com/4.4/qlistwidget.html#currentItem http://doc.trolltech.com/4.4/qlistwidget.html#setCurrentItem If the list item is changed, currentItemChanged() is emitted: http://doc.trolltech.com/4.4/qlistwidget.html#currentItemChanged And for executing, why do you want to run a Python script as external application rather than just embedding it into your own script? But if you really want to run it as external application, see os.exec*(): http://docs.python.org/library/os.html#process-management Till _______________________________________________ PyQt mailing list [email protected] http://www.riverbankcomputing.com/mailman/listinfo/pyqt
