I'm writing a Tkinter gui, also using matplotlib figures. Since I switched from a Canopy Python 2.7 distribution to a manual installed Python 2.7 installation I encounter wired problems with Tkinter checkbuttons. One can use the buttons but the variable is not set. The problem only appears when I include a matplotlib figure (see example code, 1st lin in main()).

Win7-64

Working installation:
Enthought Canopy 1.7.4.3348,
Python 2.7.11,
matplotlib 2.0.0-8

Now (not working):
Python 2.7.16,
matplotlib 2.2.4

import Tkinter as tk
import ttk as ttk
import matplotlib.pyplot as plt

class Application(tk.Frame):
 def __init__(self, gui_master):
 tk.Frame.__init__(self, gui_master)
 self.gui_master = gui_master
 self.frame = tk.Frame(self.gui_master)
 self.frame.grid()
 self.var = tk.IntVar()
 check_STD = ttk.Checkbutton(self.frame, variable= self.var, command = self.check_select)
 check_STD.grid(row = 1, column = 1)

 def check_select(self):
 print 'var', self.var, self.var.get()

def main():
 rp_fig, rp_ax = plt.subplots(1, 1, figsize = (9,9))
 gui_root = tk.Tk()
 gui_root.title("FXD-CSD-GUI")
 app = Application(gui_master=gui_root)
 gui_root.mainloop()
 plt.show()

main()

  using rp_fig = plt.Figure(figsize=(9, 9)) rp_ax = rp_fig.add_subplot(111) it works but I don't get why...

  plt.show() blocks the excution of any further code. When using matplotlib.figure.Figure() instead of plt.figure() you are not using pyplot, hence plt.show() has no figure to show and hence will not block.
