Scale widget

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 # scale widget 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
