Python | pack() method in Tkinter (original) (raw)

Last Updated : 22 Feb, 2022

The Pack geometry manager packs widgets relative to the earlier widget. Tkinter literally packs all the widgets one after the other in a window. We can use options like fill, expand, and side to control this geometry manager.
Compared to the grid manager, the pack manager is somewhat limited, but it’s much easier to use in a few, but quite common situations:

• Put a widget inside a frame (or any other container widget), and have it fill the entire frame
• Place a number of widgets on top of each other
• Place a number of widgets side by side

Code #1: Putting a widget inside frame and filling entire frame. We can do this with the help of expand and fill options.

Python3 `

Importing tkinter module

from tkinter import * from tkinter.ttk import *

creating Tk window

master = Tk()

creating a Fra, e which can expand according

to the size of the window

pane = Frame(master) pane.pack(fill = BOTH, expand = True)

button widgets which can also expand and fill

in the parent widget entirely

Button 1

b1 = Button(pane, text = "Click me !") b1.pack(fill = BOTH, expand = True)

Button 2

b2 = Button(pane, text = "Click me too") b2.pack(fill = BOTH, expand = True)

Execute Tkinter

master.mainloop()

`

Output:

Code #2: Placing widgets on top of each other and side by side. We can do this by side option.

Importing tkinter module

from tkinter import *

button widgets which can also expand and fill

in the parent widget entirely

Button 1

b1 = Button(pane, text = "Click me !", background = "red", fg = "white") b1.pack(side = TOP, expand = True, fill = BOTH)

Button 2

b2 = Button(pane, text = "Click me too", background = "blue", fg = "white") b2.pack(side = TOP, expand = True, fill = BOTH)

Button 3

b3 = Button(pane, text = "I'm also button", background = "green", fg = "white") b3.pack(side = TOP, expand = True, fill = BOTH)

Execute Tkinter

master.mainloop()
