Retrieving Values Of IntVar() Variables We can use get() method on IntVar() variable to retrieve the text value present in the variable.
x = IntVar() # Holds an integer; default value 0. x = DoubleVar() # Holds a float; default value 0.0. x = BooleanVar() # Holds a boolean, returns 0 for False and 1 for True.
A normal variable can be used to set the value for any application whenever it is required. However, we can take the user input by creating an instance of the StringVar() object.
The Tkinter StringVar helps you manage the value of a widget such as a Label or Entry more effectively. The StringVar constructor accepts three optional arguments: container is a widget that the StringVar object associated with. If you skip the container, it defaults to the root window.
I have a Checkbutton and an IntVar object associated with it, but when I try to get the value of the var, I am receiving PY_VAR0.
Here's my code:
from tkinter import *
root = Tk()
def show_state():
print(var)
var = IntVar()
cbtn = Checkbutton(root, text='Check', variable=var, command=show_state)
cbtn.pack()
root.mainloop()
Why am I getting PY_VAR0?
