In this article we’ll be covering the Tkinter grid layout manager. Tkinter grid is one out of three layout managers used to control the placement of widgets on a Tkinter window.
The other two layout managers are
place(). In this article however, we’ll simply cover Tkinter grid and it’s various usages.
Using the Grid Layout
The grid layout has 4 main options that you can use while positioning widgets.
row– The row at which the widget is to be placed
column– The column at which the widget is to be placed
columnspan– The number of columns the widget will occupy
rowspan– The number of rows the widget will occupy
There is no limit to the number of columns and rows you can have in the grid. The highest column and row numbers you enter into your grid, will become the determine the number of rows and columns.
A short example on the use of the Grid Layout in Tkinter.
import tkinter as tk root = tk.Tk() frame = tk.Frame(root) frame.pack(pady = 10, padx = 10) button1 = tk.Button(frame, text = "Button 1") button1.grid(row = 0, column = 0, padx = 5, pady = 5) button2 = tk.Button(frame, text = "Button 2") button2.grid(row = 0, column = 1, padx = 5, pady = 5) button3 = tk.Button(frame, text = "Button 3") button3.grid(row = 1, column = 0, padx = 5, pady = 5) button4 = tk.Button(frame, text = "Button 4") button4.grid(row = 1, column = 1, padx = 5, pady = 5) root.mainloop()
The above Tkinter window automatically divided itself into 2 columns and 2 rows after judging the input passed to it. If you want adjust the amount of space allocated to a single widget, use the
Arranging widgets in a Table-format
One of my favorite usages, is to create a spread-sheet like window through the use the Entrybox and grid system.
The concept is very simple. The grid system works of a system of rows and columns. Using two for loops enables us to set up a two dimensional system, allowing us to create entry boxes in a table like format.
from tkinter import * root = Tk() root.geometry('300x300') for x in range(10): for y in range(6): entry = Entry(root, width = 6) entry.grid(row = x, column = y) root.mainloop()
The above code produces the below output.
This code can further be customized by changing the width, changing the padding between the entry boxes etc.
