In tkinter, why winfo_height() always return 1?

This is the most easy example.

#py3
from tkinter import *
tk = Tk()
canvas = Canvas(tk, width= 500 , height = 400)
canvas.winfo_height()
#In [4]: canvas.winfo_height()
#Out[4]: 1

If it doesn't work by using pack() function, you can try to add canvas.update() after using canvas.pack().

You have to pack the canvas element in the window before getting it's height. The height return is the actual height.

>>> from tkinter import * 
>>> tk = Tk()
>>> canvas = Canvas(tk, width= 500 , height = 400)
>>> canvas.winfo_height()
1
>>> canvas.pack()
>>> canvas.winfo_height()
402
