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
