AttributeError: 'QEvent' object has no attribute 'pos' #11607
Description
Since #9814, moving the mouse on a Qt4Agg window raises the exception
Traceback (most recent call last):
File "/home/antony/src/extern/matplotlib/lib/matplotlib/backends/backend_qt5.py", line 294, in enterEvent
x, y = self.mouseEventCoords(event.pos())
AttributeError: 'QEvent' object has no attribute 'pos'
(Qt5 instead uses a QEnterEvent here, which does have a pos()).
