  • Worked really flawless, super example to begin GUI learning with Python Tk.

    One thing to note, should compile with python 3.* versions as 2.* versions have Tkinter with cap “T” and 3.* versions have tkinter with small “t”.

    Keep posting more stuff, on complicated GUI’s with Tk.
    Thanks,
