Container Widgets
The
Tkinter
module supplies widgets whose purpose is
to contain other widgets. A Frame
instance does
nothing more than act as a container. A Toplevel
instance (including Tkinter
’s
root
window, also known as
the application’s main window) is a top-level
window, so your window manager interacts with it (typically by
supplying suitable decoration and handling certain requests). To
ensure that a widget parent
, which must be
a Frame
or Toplevel
instance,
is the parent (also known as master) of another widget
child
, pass
parent
as the first parameter when you
instantiate
child
.
Frame
Class
Frame
represents a rectangular area of the screen
contained in other frames or top-level windows.
Frame
’s only purpose is to
contain other widgets. Option borderwidth
defaults
to 0
, so an instance of Frame
normally displays no border. You can configure the option with
borderwidth=1
if you want the frame
border’s outline to be visible.
Toplevel
Class Toplevel
represents a rectangular area of the screen that is a top-level
window and therefore receives decoration from whatever window manager
handles your screen. Each instance of Toplevel
can
interact with the window manager and can contain other widgets. Every
program using Tkinter
has at least one top-level
window, known as the root window. You can instantiate
Tkinter
’s root window explicitly
using root
=Tkinter.Tk( )
; otherwise Tkinter
instantiates its root window implicitly as and when first needed. If you want to have more ...
