Tkinter: is there a way to check checkboxes by default?

Question

I have this piece of code that will create a simple checkbox :

from Tkinter import *

CheckVar = IntVar()
self.checkbutton = Checkbutton(self.root, text = \"         


        

Answer 1

I think the function you are looking for is .select()

This function selects the checkbutton (as can be assumed from the function name)

Try calling this function after your widget is defined:

from Tkinter import *

CheckVar = IntVar()
self.checkbutton = Checkbutton(self.root, text = "Test", variable = CheckVar)
self.checkbutton.select()

By calling the function right after the widget is created, it looks as though it's selected by default.
