How to log uncaught exceptions of a QApplication?

Where should i use an except block in order to log exceptions of a QApplication?

This doesn't seem to work:

app = QtGui.QApplication(sys.argv)
MainWindow = MainWindow()
MainWindow.show()
try:
    eventLoop = app.exec_()
except Exception, e:
    log.exception(str(e))

as the exception won't even reach that block.

Solution

  • I solved it by overriding the excepthook, as seen in the following answer: Logging All Exceptions in a pyqt4 app
