Thank you, that works for me. But for some reason, the "y" coordinate is
inversed in Qt and matplotlib? I have to specify

def get_lines_at_point(self, point):
    mpl_event = MouseEvent('button_press_event', self, 
                           point.x(), self.height() - point.y())
                                      #########################
    ret = [ ]
    for line in self.axes.get_lines():
        picked, details = line.contains(mpl_event)
        if picked:
            ret.append(line)
    return ret

The other question that now remains is: how can I remove a line from an
axes?

Best regards

Ole
