Tkinter 'textvariable' does not work in a secondary window? - Avispon99 - Aug 1, 2019
Because when I use textvariable from a secondary window that was called from a command in another window, the value set through .set () is not reflected in the secondary window Label.
Example:
Code
import tkinter as tk
def test():
ven=tk.Tk()
v1=tk.StringVar()
v1.set('TEST')
print(v1.get())
tk.Label(ven, textvariable=v1).pack()
ven.mainloop()
win=tk.Tk()
tk.Button(text='BOTON',command=test).pack()
win.mainloop()In this case, the 'TEST' message set through v1.set () is not updated in the text variable of the Label that was created in the test() function
Why does this happen?
