Tkinter: 'NoneType' object has no attribute 'bind

I'm using pandastable to implement a pandas dataframe into my tkinter window however, an error:

'NoneType' object has no attribute 'bind_all'

Keeps coming up when I use this line:

table = pt = Table(window, dataframe=stats)

full code:

import tkinter as tk
import pandas as pd
from pandastable import Table, TableModel

places = {"Place":['1st'], "Name":['Derik'], "Time":['1.89']}
window = tk.Tk()

stats = pd.DataFrame.from_dict(places)
table = Table(window, dataframe=stats)

CodePudding user response：

The error is because pandastable wants you to put the widget inside a container and not a window. You can find this out by checking the line 88 and line 264 of the pandastable source code:

class Table(Canvas):
    ...
    def __init__(self, parent=None, model=None, dataframe=None, ...):

        self.parentframe = parent # Line 88

        ...

    def doBindings(self):
        ...
        self.parentframe.master.bind_all("<KP_8>", self.handle_arrow_keys) # Line 264

As you can see, self.parentframe is the parent you pass in, in your case, window. And in line 264, they access the master of the self.parentframe, which is None because root windows don't have masters. But other widgets like frames do.

So all you have to do is, put this widget inside a container like Frame:

frame = tk.Frame(window)
frame.pack()

table = Table(frame, dataframe=stats)
table.show()
