Remove option from NavigationToolbar2TkAgg? - matplotlib

Question

I'm learning how to use matplotlib, and now I have a problem. When I create a Figure in "tkinter project" and give it a subplot, I use NavigationToolbar2TkAgg to create a toolbar. In the current toolbar that appears , i want to remove the configure subplot option but couldn't find a way to do so.
Is there any way to do it?

The solution to this is in principle already given in this question: How to modify the navigation toolbar easily in a matplotlib figure window?
But it may not be obvious how to use it. So we may adapt the code from here with a CustomToolbar. The Toolbars toolitems attribute can be changed as to remove the unwanted "Subplots" button.
import numpy as np
import Tkinter as tk
import matplotlib as mpl
from matplotlib.patches import Rectangle
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
# custom toolbar with lorem ipsum text
class CustomToolbar(NavigationToolbar2TkAgg):
toolitems = filter(lambda x: x[0] != "Subplots", NavigationToolbar2TkAgg.toolitems)
class MyApp(object):
def __init__(self,root):
self.root = root
self._init_app()
# here we embed the a figure in the Tk GUI
def _init_app(self):
self.figure = mpl.figure.Figure()
self.ax = self.figure.add_subplot(111)
self.canvas = FigureCanvasTkAgg(self.figure,self.root)
self.toolbar = CustomToolbar(self.canvas,self.root)
self.toolbar.update()
self.plot_widget = self.canvas.get_tk_widget()
self.plot_widget.pack(side=tk.TOP, fill=tk.BOTH, expand=1)
self.toolbar.pack(side=tk.TOP, fill=tk.BOTH, expand=1)
self.canvas.show()
# plot something random
def plot(self):
self.ax.plot([1,3,2])
self.figure.canvas.draw()
def main():
root = tk.Tk()
app = MyApp(root)
app.plot()
root.mainloop()
if __name__ == "__main__":
main()
Note: In newer versions of matplotlib you should use NavigationToolbar2Tk instead of NavigationToolbar2TkAgg
