I'm using the .place method. The following code is a working simplification of resizable columns and the error message which occurs while mouse-moving the columns after a short time.

import tkinter as tk





def column_drag(event):

    #print(event.x)

    for ii, i in enumerate(column_head):

        if ii != 0:

            currCur = root.winfo_pointerx() - root.winfo_rootx()

            if currCur <= column_head[ii].winfo_x() + 10 and currCur >= column_head[ii].winfo_x() - 10:

                if currCur <= column_head[ii].winfo_x() + 10 and currCur >= column_head[ii].winfo_x() - 10:

                    column_head[ii].configure(cursor="sb_h_double_arrow")

                    column_posx[ii] = currCur

                    column_user[ii] = True

                refresh_run_display()

            else: column_head[ii].configure(cursor="arrow")



def resize(event):

    refresh_run_display()





def refresh_run_display():

    ii = len(column_body)-1

    for i in reversed(column_body):

        # Last column

        if ii+1 == len(column_body):

            if column_user[ii] is False:

                column_head[ii].place(x=ii * 150, y=0, height=20, width=root.winfo_width())

                column_head[ii].update()

                column_body[ii].place(x=ii * 150, y=column_head[ii].winfo_height(), height=120, width=root.winfo_width())

I'd like to keep the current format if possible. Please help!

I think the column_head[ii].update() is causing this error.

Before, In testing column_head[ii].winfo_height() would return an incorrect value when asked to return its value in the next line:
column_head[ii].place(x=ii * 150, y=0, height=20, width=root.winfo_width())

column_head[ii].update() solved this but apparently now it is not necessary and commenting out all column_head[ii].update() seems to have worked. It was the line called out in the debug
