Python tkinter ttk horizontal or vertical separator

Separator is part of Tkinter ttk module. ( What is ttk ? )

separator horizontal

from tkinter import ttk
import tkinter as tk

my_w = tk.Tk()
my_w.geometry("550x440") # width and height of window 
my_w.title("www.plus2net.com") # title
font1=['Times',32,'normal'] # font family , size and style


lb1=tk.Label(my_w,text=' Label 1 \n at top side ',
             height=3, width=15,bg='yellow',font=font1)
lb1.grid(row=1,column=1,padx=20,pady=20)

sp1=ttk.Separator(my_w,orient='horizontal')
sp1.grid(row=2,column=1,sticky='ew')

lb2=tk.Label(my_w,text='Label 2 \n at bottom side',
             height=3,width=15,bg='yellow',font=font1)
lb2.grid(row=3,column=1,padx=10,pady=20)

my_w.mainloop()  # Keep the window open

vertical separator

from tkinter import ttk
import tkinter as tk

my_w = tk.Tk()
my_w.geometry("550x440") # width and height of window 
my_w.title("www.plus2net.com") # title
font1=['Times',32,'normal'] # font family , size and style


lb1=tk.Label(my_w,text='Label 1 \n at Left side',height=6,bg='yellow',font=font1)
lb1.grid(row=1,column=1,padx=20,pady=20)

sp1=ttk.Separator(my_w,orient='vertical')
sp1.grid(row=1,column=2,sticky='ns')

lb2=tk.Label(my_w,text='Label 2 \n at Right side',height=6,bg='yellow',font=font1)
lb2.grid(row=1,column=3,padx=10,pady=20)

my_w.mainloop()  # Keep the window open

With Style

from tkinter import ttk
import tkinter as tk

my_w = tk.Tk()
my_w.geometry("550x440") # width and height of window 
my_w.title("www.plus2net.com") # title
font1=['Times',32,'normal'] # font family , size and style

s = ttk.Style()
s.configure('TSeparator', foreground='blue',background='red')

lb1=tk.Label(my_w,text=' Label 1 \n at top side ',
             height=3, width=15,bg='yellow',font=font1)
lb1.grid(row=1,column=1,padx=20,pady=20)

sp1=ttk.Separator(my_w,orient='horizontal')
sp1.grid(row=2,column=1,sticky='ew')

lb2=tk.Label(my_w,text='Label 2 \n at bottom side',
             height=3,width=15,bg='yellow',font=font1)
lb2.grid(row=3,column=1,padx=10,pady=20)

my_w.mainloop()  # Keep the window open

Tkinter Separators: Vertical & Horizontal Orientations

Dynamically Adding Separators in Tkinter by looping

While iterating through my data to dynamically create labels in Tkinter, I also incorporate ttk separators for enhanced visual organization. For each label generated from the data, I instantiate a ttk Separator and place it directly below the corresponding label. This approach helps me visually distinguish between different rows of information, greatly improving the clarity and aesthetic appeal of my GUI, especially when displaying numerous data entries from a database or various sources.

import tkinter  as tk 
from tkinter import ttk
my_w = tk.Tk()
font1=('Times',28,'normal') # font family, size, style
width,height=400,200
d=str(width)+"x"+str(height) 
my_w.geometry(d)  # width and height of the window

l1=[['abc','def','ghi','jkl'],
    ['mno','pkr','frt','qwr'],
    ['asd','air','abc','zpq'],
    ['zae','vbg','qir','zab']]

my_row,my_col=1,0 # First row and first column values are set here
my_labels=[] # to store the reference of all Labels 

for data in l1: # get each row of the list as data 
    for my_col in range(len(data)): # get each element of the row of data
        my_label=tk.Label(my_w,text=data[my_col],font=font1)
        my_label.grid(row=my_row,column=my_col,padx=10,pady=5)
        my_labels.append(my_label) # add the reference 

    sp=ttk.Separator(my_w,orient='horizontal')
    sp.grid(row=my_row+1,column=0,sticky='ew',columnspan=my_col+1)
    my_row=my_row+2 # Jump by two rows 
            
height=my_row*30 #  calculate new height based on number of rows
d=str(width)+"x"+str(height) # string with new height
my_w.geometry(d) # Update the dimension of the window 
my_labels[4].config(bg='yellow') 

my_w.mainloop()

Dynamically adding rows and columns to create a grid

Dynamically adding vertical and horizontal separators

In above code inside the for loop we will add vertical sparators so we can create a grid and display our data

import tkinter  as tk 
from tkinter import ttk
my_w = tk.Tk()
my_w.title("www.plus2net.com")  # Adding a title
font1=('Times',36,'normal') # font family, size, style
width,height=480,300
d=str(width)+"x"+str(height) 
my_w.geometry(d)  # width and height of the window

l1=[['abc','def','ghi','jkl'],
    ['mno','pkr','frt','qwr'],
    ['asd','air','abc','zpq'],
    ['zae','vbg','qir','zab']]

my_row=1 # First row  value set here
my_labels=[] # to store the reference of all Labels 

for data in l1: # get each row of the list as data 
    for my_col in range(len(data)): # get each element of the row of data
        my_label=tk.Label(my_w,text=data[my_col],font=font1)
        my_label.grid(row=my_row,column=my_col+2,padx=15,pady=5)

        sp1=ttk.Separator(my_w,orient='vertical')
        sp1.grid(row=my_row,column=my_col+1,sticky='nse')
        
        my_labels.append(my_label) # add the reference 

    sp2=ttk.Separator(my_w,orient='horizontal')
    sp2.grid(row=my_row+1,column=0,sticky='ew',columnspan=my_col+4)
    my_row=my_row+2 # Jump  to Next row 
            
height=my_row*35 #  calculate new height based on number of rows
d=str(width)+"x"+str(height) # string with new height
my_w.geometry(d) # Update the dimension of the window 

my_w.mainloop()
