Button Text Of Tkinter Does Not Work In Mojave

It is very simple program. import tkinter tkinter.Button(None, text='button').pack() tkinter.mainloop() I expect this program shows me such as a below picture. But it shows a bel

Solution 1:

Changing Appearance to Light Mode fixed this problem for me.

To change appearance, go to Settings -> General -> Appearance -> Light Mode.

Solution 2:

I guess there is a bug in Tk. I am on MacOS 10.14.3 If you maximize and minimize the tkinter window the text on the button appears, another solution that worked for me is

from tkinter import *
from tkinter import ttk

button1 = ttk.Button(*your args here*)

Solution 3:

I had this same exact error, and to get it fixed I had to change my buttons to ttk.Button and set a style. For example, add the following to import:

try: from tkinter import ttk # python 3except: import ttk # python 2.7

And then after the root init:

    style = ttk.Style()
    style.map("C.TButton",
              foreground=[('pressed', 'red'), ('active', 'blue')],
              background=[('pressed', '!disabled', 'black'),
                          ('active', 'white')]
              )

Then when you are instantiating the Button:

self.button = ttk.Button(self, text="my cooool button",
                                 command=self.load_something_cool, style="C.TButton")

It worked perfectly to ensure that the text is displayed properly. Before I added the ttk bit, I was in the same boat as you in Mojave.

Solution 4:

I also had this problem, 100% reproducible on my Mac after upgrading to Mojave and when using Homebrew's python3.

Switching to Python.org 's Python 3.7.1 package download totally eliminated the problem for me.

Solution 5:

Here's an example that patches up the problem for me (at least until the Python/Tkinter stuff gets cleaned up):

import tkinter
root = tkinter.Tk()
tkinter.Button(root, text='button').pack()
deffix():
    a = root.winfo_geometry().split('+')[0]
    b = a.split('x')
    w = int(b[0])
    h = int(b[1])
    root.geometry('%dx%d' % (w+1,h+1))
root.update()
root.after(0, fix)
tkinter.mainloop()

This was tested on macOS Version 10.14.2 (18C54) and Python 3.7.2 (loaded via Home-brew).
