Python tkinter Grid for layout in rows and columns

Layout of the page to place the components in rows and columns.

Empty rows and columns are ignored. ( row=3 is same as row=1 if row=1 and row=2 are not used)

Another method of layout is Pack, never mix Pack and grid in same window.

We will keep one Label along with an Entry box.

Understanding row and column

Tkinter Grid layout management by row & columns & aligning in both horizontal & vertical directions

Horizontal placement is done by rows and vertical placement is done by columns.
Tkinter row and column

import tkinter as tk
my_w = tk.Tk()
my_w.geometry("300x200")  

l1 = tk.Label(my_w, text='row=1,column=1 ')
l1.grid(row=1,column=1) 

l2 = tk.Label(my_w, text=' row=1,column=2')
l2.grid(row=1,column=2) 

l3 = tk.Label(my_w, text='row=2,column=1 ')
l3.grid(row=2,column=1) 

l4 = tk.Label(my_w, text=' row=2,column=2')
l4.grid(row=2,column=2) 

my_w.mainloop()

The top line is row=1 and second line is row=2, similarly first vertical column is column=1 and next vertical column is column=2

sticky option

If the component size is less than the available grid space, then we can use 'E','W','N','S' to align right left top and bottom.

Check F Name and L Name is aligned to left and right. We can align the components to top and bottom also.
Tkinter grid sticky

import tkinter as tk
my_w = tk.Tk()
my_w.geometry("250x100")  
my_w.title("plus2net.com")  # Adding a title

l1 = tk.Label(my_w,  text='F Name (sticky=\'W\')' ) #added one Label 
l1.grid(row=1,column=1,sticky='W') 

e1 = tk.Entry(my_w,   width=10,bg='yellow') # added one Entry box
e1.grid(row=1,column=2) 

l2 = tk.Label(my_w,  text='L Name (sticky=\'E\')')  # 
l2.grid(row=2,column=1,sticky='E') 

e2 = tk.Entry(my_w,   width=10,bg='yellow') # added one Entry box
e2.grid(row=2,column=2)

l3 = tk.Label(my_w,  text='Add Door No and Street address')   
l3.grid(row=3,column=1,sticky='W') 

e3 = tk.Entry(my_w,   width=10,bg='yellow') # added one Entry box
e3.grid(row=3,column=2)

my_w.mainloop()

The option sticky='NSEW' mean occupy all the available space in all directions.

columnspan option

Tkinter window grid layout using rowspan and columnspan to manage multiple rows and columns

By default columnspan=1, we can set to different value by increasing it to expand more than one column.
Tkinter grid columnspan

l1 = tk.Label(my_w, text='First', width=20)
l1.grid(row=1,column=1) 
l2 = tk.Label(my_w, text='Second', width=20)
l2.grid(row=1,column=2) 

l3 = tk.Label(my_w, text='Both First and Second, columnspan=2')
l3.grid(row=2,column=1,columnspan=2)

rowspan options

We can use rowspan=3 to expand to three rows.
Tkinter grid rowspan

import tkinter as tk
my_w = tk.Tk()
my_w.geometry("300x150")  
l1 = tk.Label(my_w, text='First', width=20)
l1.grid(row=1,column=1) 
l2 = tk.Label(my_w, text='Second', width=20)
l2.grid(row=2,column=1) 
l3 = tk.Label(my_w, text='Third', width=20)
l3.grid(row=3,column=1) 

t1 = tk.Text(my_w,  height=3, width=8,bg='yellow') #text box
t1.grid(row=1,column=2,rowspan=3)

my_w.mainloop()

ipadx,ipady,padx,pady options

Tkinter window grid layout using padx pady and internal padding by using ipadx, ipady

ipadx and ipady adds inner padding or the internal padding of the widget border.

l4=tk.Label(my_w,text='ipadx=50,ipady=50',
	borderwidth=2,relief='ridge')
l4.grid(row=2,column=2,ipadx=50,ipady=50)

padx and pady adds padding from the widget to the grid boarder.

l4=tk.Label(my_w,text='padx=50,pady=50',
	borderwidth=2,relief='ridge')
l4.grid(row=2,column=2,padx=50,pady=50)

grid_size()

This will return a tuple showing first empty columns and rows . In this example we have used upto row=3 and column=3 so we will get output as (4,4).

import tkinter as tk
my_w = tk.Tk()
my_w.geometry("300x150")  
l1 = tk.Label(my_w, text='First', width=8)
l1.grid(row=1,column=1) 
l2 = tk.Label(my_w, text='Second', width=8)
l2.grid(row=2,column=2) 
l3 = tk.Label(my_w, text='Third', width=8)
l3.grid(row=3,column=3) 

print(my_w.grid_size()) # tuple  columns , rows 

my_w.mainloop()

Output

(4, 4)

You can remove the last element and check the output. We will set the value as column=2 for last element.

l3 = tk.Label(my_w, text='Third', width=8)
l3.grid(row=3,column=2)

Output

(3, 4)

grid_slaves(row=None, column=None)

We will get a list of widgets manage by the grid.

import tkinter as tk
my_w = tk.Tk()
my_w.geometry("300x150")  
l1 = tk.Label(my_w, text='First', width=8)
l1.grid(row=1,column=1) 
l2 = tk.Label(my_w, text='Second', width=8)
l2.grid(row=2,column=2) 
l3 = tk.Label(my_w, text='Third', width=8)
l3.grid(row=3,column=2) 

print(my_w.grid_slaves()) 

my_w.mainloop()

Output

[<tkinter.Label object .!label3>, <tkinter.Label object .!label2>,
 <tkinter.Label object .!label>]

We can use row and column number to get the widget.

print(my_w.grid_slaves(2,2))

Output

[<tkinter.Label object .!label2>]

grid_remove()

Remove the widget from the perticular grid. Can be added again.

import tkinter as tk
my_w = tk.Tk()
my_w.geometry("300x150")  
l1 = tk.Label(my_w, text='First', width=8)
l1.grid(row=1,column=1) 
l2 = tk.Label(my_w, text='Second', width=8)
l2.grid(row=2,column=2) 
l3 = tk.Label(my_w, text='Third', width=8)
l3.grid(row=3,column=2) 
l3.grid_remove()
my_w.mainloop()

To restore the widget in same location we have to just use grid()

l3.grid()

grid_forget()

Remove the widget from the perticular grid. Can be added again at the new location. We have to specify the location while restoring, by default it takes the next new location.

l3.grid_forget()

To restore at the same location we have to specify the row and column.

l3.grid(row=3,column=2)

Removing after some time delay

We can use the widget as message box and want to remove it after 300 seconds.

l3.after(3000, lambda: l3.grid_remove() )

Remove all widgets

for w in my_w.grid_slaves(): # Loop through each row 
    w.grid_forget() # remove the row

Remove all widgets of 2nd row only

for w in my_w.grid_slaves(2):
    w.grid_forget()

or , any one of these lines will work

#for w in my_w.grid_slaves(2): #  
    #    w.grid_forget()  # remove all elements of 2nd row 
#for w in my_w.grid_slaves(2):w.grid_forget()
[w.grid_forget() for w in my_w.grid_slaves(2)]

Remove all widgets of 2nd column

for w in my_w.grid_slaves(None,2):
    w.grid_forget()

Delete widgets

By using destroy() method we can delete a widget permanently. We can't restore it again.

import tkinter as tk
my_w = tk.Tk()
my_w.geometry("300x150")  

b1=tk.Button(my_w,text='Hide: \n grid_forget()',
      command=lambda:l1.grid_forget())
b1.grid(row=0,column=0,padx=2,pady=10)
b2=tk.Button(my_w,text='Display : \n grid()',
      command=lambda:l1.grid())
b2.grid(row=0,column=1,padx=2,pady=10) 
b3=tk.Button(my_w,text='Destroy : \n destroy()',
      command=lambda:l1.destroy())
b3.grid(row=0,column=2,padx=2)

l1 = tk.Label(my_w, text='Hi Welcome', width=10)
l1.grid(row=1,column=0,pady=10) 
my_w.mainloop()

By using grid_slaves() and grid_forget() we can refresh the window after any delete or update operation. See example of deleting record

grid_info()

All information about the widget layout in the grid.

import tkinter  as tk 
from tkinter import *
my_w = tk.Tk()
my_w.geometry("400x200")  # Size of the window 
my_w.title("www.plus2net.com")  # Adding a title
l1 = tk.Label(my_w, text='row=1,column=1 ')
l1.grid(row=1,column=1,padx=10,pady=10,ipadx=3,ipady=4) 

#dictionary elements(row,column,ipadx,ipday,sticky,rowspan,columnspan)
print(l1.grid_info()) # dictionary all elements value 
print(l1.grid_info()['column'])# 1
print(l1.grid_info()['padx'])  # 10         

my_w.mainloop()  # Keep the window open
