Tkinter Tutorial - Scale

A Scale is the widget that user could select a numerical value from the range of values by moving a slider knob along the scale.

You could specify the minimum and maximum values and also the resolution of the scale. The scale provides a bounded numerical value compared to a Entry widget.

Tkinter Scale Example

import tkinter as tk
 
app = tk.Tk() 
app.geometry('300x200')
app.title("Basic Scale")

scaleExample = tk.Scale(app, from_=0, to=10)
scaleExample.pack()
app.mainloop()

scaleExample = tk.Scale(app, from_=0, to=10)

from_ specifies the minimum value, and to specifies the maximum value of the range.

Tkinter Scale Orientation and Resolution

import tkinter as tk
 
app = tk.Tk() 
app.geometry('300x200')
app.title("Tkitner Scale Example")

scaleExample = tk.Scale(app,
                        orient='horizontal',
                        resolution=0.1,
                        from_=0,
                        to=10)
scaleExample.pack()
app.mainloop()

scaleExample = tk.Scale(app,
                        orient='horizontal',
                        resolution=0.1,
                        from_=0,
                        to=10)

orient='horizontal'

The default orientation of Tkinter scale is vertical as shown in the first example. You need to specify the orient attribute of scale to be horizontal to get a horizontal Tkinter scale.

resolution=0.1

The resolution of the scale could be modified by resolution option that has the default value of 1.
