Tkinter is a GUI toolkit used in python to make user-friendly GUIs.Tkinter is the most commonly used and the most basic GUI framework available in python. Tkinter uses an object-oriented approach to make GUIs.Note: For more information, refer to Python GUI – tkinter

The Scale widget is used whenever we want to select a specific value from a range of values. It provides a sliding bar through which we can select the values by sliding from left to right or top to bottom depending upon the orientation of our sliding bar.Syntax:

S = Scale(root, bg, fg, bd, command, orient, from_, to, ..)

Optional parameters

root - root window.
bg - background colour
fg - foreground colour
bd - border
orient - orientation(vertical or horizontal)
from_ - starting value
to - ending value
troughcolor - set colour for trough.
state - decides if the widget will be responsive or unresponsive.
sliderlength - decides the length of the slider.
label - to display label in the widget.
highlightbackground - the colour of the focus when widget is not focused.
cursor - The cursor on the widget which could be arrow, circle, dot etc.

Methods

set(value) - set the value for scale.
get() - get the value of scale.

Example 1: Creating a horizontal bar

Python3 1== `

Python program to demonstrate

from tkinter import *

root = Tk()
root.geometry("400x300")

v1 = DoubleVar()

def show1():

sel = "Horizontal Scale Value = " + str(v1.get())
l1.config(text = sel, font =("Courier", 14))

s1 = Scale( root, variable = v1, from_ = 1, to = 100, orient = HORIZONTAL)

l3 = Label(root, text = "Horizontal Scaler")

b1 = Button(root, text ="Display Horizontal", command = show1, bg = "yellow")

l1 = Label(root)

s1.pack(anchor = CENTER) l3.pack() b1.pack(anchor = CENTER) l1.pack()

root.mainloop()

Output: python-tkinter-scale Example 2: Creating a vertical slider

Python3 1== `

from tkinter import *

root = Tk()
root.geometry("400x300") v2 = DoubleVar()

def show2():

sel = "Vertical Scale Value = " + str(v2.get()) 
l2.config(text = sel, font =("Courier", 14))

s2 = Scale( root, variable = v2, from_ = 50, to = 1, orient = VERTICAL)

l4 = Label(root, text = "Vertical Scaler")

b2 = Button(root, text ="Display Vertical", command = show2, bg = "purple", fg = "white")

l2 = Label(root)

s2.pack(anchor = CENTER) l4.pack() b2.pack() l2.pack()

root.mainloop()

Output: python-tkinter-scale
