[SOLVED] How can I detect double click events in matplotlib?

How can I detect double click events in matplotlib?

import matplotlib.pyplot as plt

def onclick(event):
    print(event.button)

fig = plt.figure()
connection_id = fig.canvas.mpl_connect('button_press_event', onclick)
plt.show()

With this code, the problem is double-clicks are hitting onclick() handler three times. I guess that it is receiving both the clicks, as well as an additional double-click event.

How can I change this behavior so that the event handler is not fired for double-click events? Alternatively, how can I detect a double-click from the event instance so that I can ignore that case?

Note: button_release_event does not have this problem, but I want to fire on the button_press_event

Solution

When i had matplotlib version 1.1rc, i was not able to catch dblclick event. Later, I wrote code for matplotlib 1.2 and that is ok

import matplotlib.pyplot as plt
fig = plt.figure()
def onclick(event):
    if event.dblclick:
         print event.button

connection_id = fig.canvas.mpl_connect('button_press_event', onclick)
plt.show()
