The following two examples are from Grayson's book on Tkinter. He's making a
simple dialog with three buttons. In the first example, he does not use the
Frame class, but in the second he does. Doesn't the first example need a
container? What's the difference here?
==============5.1============
from Tkinter import *
class App:
def __init__(self, master):
Button(master, text='Left').pack(side=LEFT)
Button(master, text='Center').pack(side=LEFT)
Button(master, text='Right').pack(side=LEFT)
root = Tk()
root.option_add('*font', ('verdana', 12, 'bold'))
root.title("Pack - Example 1")
display = App(root)
root.mainloop()
==============5.2==============
from Tkinter import *
class App:
def __init__(self, master):
fm = Frame(master)
Button(fm, text='Left').pack(side=LEFT)
Button(fm, text='This is the Center button').pack(side=LEFT)
Button(fm, text='Right').pack(side=LEFT)
fm.pack()
root = Tk()
root.option_add('*font', ('verdana', 12, 'bold'))
root.title("Pack - Example 2")
display = App(root)
root.mainloop()
