Tkinter GUI #17 | Scale

The Scale widget in Tkinter is used to provide a graphical slider that allows the user to select a value within a specified range. It is a very useful widget for adding sliders to your GUI applications.

Usage

The Scale widget is created using the Scale class in Tkinter. Here is an example code snippet that creates a Scale widget with a range from 0 to 100:

        import tkinter as tk

        root = tk.Tk()

        scale = tk.Scale(root, from_=0, to=100)
        scale.pack()

        root.mainloop()
    

In the above code, we first import the tkinter module and create a root window. We then create a Scale widget with a range from 0 to 100 using the Scale class. Finally, we pack the Scale widget into the root window and start the Tkinter main event loop.

Properties

The Scale widget has several properties that can be used to customize its appearance and behavior. Some of the most commonly used properties include:

• from_: Specifies the starting value of the scale
• to: Specifies the ending value of the scale
• orient: Specifies the orientation of the scale (horizontal or vertical)
• length: Specifies the length of the scale
• label: Specifies a label for the scale
• command: Specifies a callback function to be called when the value of the scale changes

Conclusion

The Scale widget in Tkinter is a versatile and easy-to-use widget for creating sliders in your GUI applications. By customizing the properties of the Scale widget, you can create sliders that fit the specific needs of your application.
