Tkinter syntax code example

Example 1: tkinter basic

from tkinter import Tk, Label, Button

class MyFirstGUI:
    def __init__(self, master):
        self.master = master
        master.title("A simple GUI")

        self.label = Label(master, text="This is our first GUI!")
        self.label.pack()

        self.greet_button = Button(master, text="Greet", command=self.greet)
        self.greet_button.pack()

        self.close_button = Button(master, text="Close", command=master.quit)
        self.close_button.pack()

    def greet(self):
        print("Greetings!")

root = Tk()
my_gui = MyFirstGUI(root)
root.mainloop()

Example 2: functions calling upon creation tkinter fix

Make your event handler a lambda function, which calls your command() - in this case get_dir()
- with whatever arguments you want:

xbBrowse = Button(frameN, text="Browse...", font=fontReg, command=lambda : self.get_dir(xbPath))
