    Description

       Steps to reproduce:

      • Left click
      • Right click,. note error below
        """
        Repro:
        1. Run `python tests/python/test_event_exception.py`
        2. Right-click and nothing bad happens
        3. Left click to cause exception
        4. Right-click and see event exception
        """
        from PySide2 import QtWidgets, QtCore
        
        class Widget(QtWidgets.QWidget):
        
            def mouseReleaseEvent(self, event):
                print("\nmouseReleaseEvent :: event type: %r" % type(event))
                if event.button() == QtCore.Qt.LeftButton:
                    raise Exception("FOO")
        
            def contextMenuEvent(self, event):
                print("contextMenuEvent :: event type: %r" % type(event))
                super(Widget, self).contextMenuEvent(event)
        
        app = QtWidgets.QApplication(["event_repro"])
        
        widget = Widget()
        widget.show()
        
        app.exec_()
        

         

      The exception produced:

      Traceback (most recent call last):
      File "tests/python/test_event_exception.py", line 38, in mouseReleaseEvent
        raise Exception("FOO")
      Exception: FOO

      then causes the exception the next time right-click is pressed
