I seem to have run into this problem with wx years ago -- destroying the
widget that fed an event from a callback causes issues. As Chris
suggested, the following seems to work, however:
import matplotlib.pyplot as plt
import wx
def close_figure():
plt.close()
def onclick(event):
if event.button==1:
wx.CallAfter(close_figure)
fig = plt.gcf()
cid = fig.canvas.mpl_connect('button_press_event', onclick)
plt.show()
