I have a little update on the issue: I tried it with different versions of
python and matplotlib and it is still present in
python 2.7.6 + matplotlib 1.4.2
but it works as expected in
python 3.4.0 + matplotlib 1.4.2
Should this be reported as a bug in matplotlib 1.4.2 on python 2.7.6?
BTW, I noticed that my minimal text from previous mail didn't get through to
the mailing list, so I am attaching it again (modified for python 2.7)
without formatting:
from __future__ import print_function
import sys
if sys.version_info < (3, 0):
import Tkinter as tk
else:
import tkinter as tk
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
import matplotlib.figure as mplfig
class Test:
def on_press(self, event):
print("clicked2")
def connect(self, canvas):
self.cidpress = canvas.mpl_connect(
'button_press_event', self.on_press)
self.cidpress = canvas.mpl_connect(
'button_press_event', lambda event: print("clicked1"))
class App(object):
def on_press(self, event):
print("clicked0")
def __init__(self, master):
self.fig = mplfig.Figure()
self.canvas = FigureCanvasTkAgg(self.fig, master=master)
dl = Test()
dl.connect(self.canvas)
self.cidpress = self.canvas.mpl_connect(
'button_press_event', self.on_press)
self.canvas.get_tk_widget().pack()
self.canvas.draw()
if __name__ == "__main__":
root = tk.Tk()
app = App(root)
tk.mainloop()
this should print
clicked2
clicked1
clicked0
after each click on the canvas. But in python 2.7.6 it prints only
clicked1
clicked0
