I have this python code for make GUI through tkinter.
I'm trying to activate a new form(form2) on the top when I press the button on Form 1.
I developed based on the inheritance of tkinter class.
My code usually works well, but I found one problem.
If I run Form 2 through the button event on Form 1, the font on Form 2 is not changed.
Errors do not occur at all.
but, if I run it right from the main as below, the font will be changed successfully.
if __name__ == '__main__':
form2 = Form2()
form2.mainloop() # execute GUI
This is my Code:
from tkinter.ttk import *
import tkinter as tk
from tkinter import messagebox
from tkinter import *
import tkinter.font as tkFont
class Form2(tk.Tk):
def __init__(self):
super().__init__() # Inheritance from tkinter class
self.title("Form2")
self.geometry("350x600")
self.resizable(0, 0)
self.label = tk.Label(self, text='form2',
font=tkFont.Font(family="Roboto", size=18))
self.label.pack()
class Form1(tk.Tk):
def __init__(self):
super().__init__() # Inheritance from tkinter class
self.title("Form1")
self.geometry("350x600")
self.resizable(0, 0)
# Get Language Data
self.label = tk.Label(self, text='form1',
font=tkFont.Font(family="Roboto", size=18))
self.label.pack()
# preferences button design
self.button: object = tk.Button(self, overrelief="solid", width=10, height=2,
repeatdelay=1000, repeatinterval=100,
text="Preferences",
font=tkFont.Font(family="Roboto", size=9),
command=lambda: self.button_clicked())
self.button.pack()
@staticmethod
def button_clicked():
form2 = Form2()
form2.mainloop()
if __name__ == '__main__':
form1 = Form1()
form1.mainloop()
Please give me some advice.
