Python GUI Tk : Frame

Create additional windows: use the Toplevel widget.

from Tkinter import *
    
root = Tk()
    
top = Toplevel()
    
root.mainloop()

Change Frame title

import Tkinter
root = Tkinter.Tk()
var = Tkinter.StringVar()
entry = Tkinter.Entry(root, textvariable=var)
entry.focus_set()
entry.pack()
var.set(root.title())
def changeTitle(): root.title(var.get())
Tkinter.Button(root, text="Change Title", command=changeTitle).pack()
Tkinter.mainloop()

Frame action: Iconify

import Tkinter
root = Tkinter.Tk()
var = Tkinter.StringVar()
entry = Tkinter.Entry(root, textvariable=var)
entry.focus_set()
entry.pack()
var.set(root.title())
def changeTitle(): root.title(var.get())
Tkinter.Button(root, text="Iconify", command=root.iconify).pack()
Tkinter.mainloop()

Frame action: close

import Tkinter
root = Tkinter.Tk()
var = Tkinter.StringVar()
entry = Tkinter.Entry(root, textvariable=var)
entry.focus_set()
entry.pack()
var.set(root.title())
def changeTitle(): root.title(var.get())

Tkinter.Button(root, text="Close", command=root.destroy).pack()
Tkinter.mainloop()

Creating a window

from Tkinter import *

# create the root window
root = Tk()

# modify the window
root.title("Create a window")
root.geometry("200x200")

# Start the window's event-loop
root.mainloop()

Default top level root window

from Tkinter import *

root = Tk()
root.title('Toplevel')
Label(root, text='This is the main (default) Toplevel').pack(pady=10)

root.mainloop()

A child of root window

from Tkinter import *

root = Tk()
t1 = Toplevel(root)
Label(t1, text='This is a child of root').pack(padx=10, pady=10)

root.mainloop()

Transient window of root

from Tkinter import *

root = Tk()
t2 = Toplevel(root)
Label(t2, text='This is a transient window of root').pack(padx=10, pady=10)
t2.transient(root)

root.mainloop()

Frame without decorations

from Tkinter import *

root = Tk()
t3 = Toplevel(root, borderwidth=5, bg='blue')
Label(t3, text='No wm decorations', bg='blue', fg='white').pack(padx=10, pady=10)
t3.overrideredirect(1)
t3.geometry('200x70+150+150')

root.mainloop()

Using Tk option database to configure Tk widgets

Set Frame background color

    fm.pack(side=TOP, expand=NO, fill=NONE)
