A Tkinter Spinbox provides a numerical input field with increment and decrement buttons. It allows users to select a value from a range of predefined options. It is like a combination of an Entry widget and a set of Arrow buttons.  

 

You should import the Spinbox class from the tkinter module to use a GUI built with Tkinter. Spinboxes are used for numerical input. It does not support checkboxes or radio buttons. You can combine it with checkboxes or radio buttons to achieve similar functionality. Here are the different types of spinboxes and how they can be used in Tkinter:  

Spinbox:  

The Spinbox widget provides a numeric input field with up and down arrows. It helps in incrementing or decrementing the value. By default, it supports integer values but can also be configured to accept floats.  

Combobox:  

Although not a spinbox, the Combobox widget combines a text entry with a dropdown list. It can select values from a predefined set of choices.  

Scale:  

The Scale widget provides a slider control that allows the user to select a value from a range. While not a spinbox, it can be a useful alternative for continuous or discrete input.  

 

Here are some available properties, including the title, caption, and input fields:  

Title/Label:  

The title or label property is used to set the text. It appears alongside the SpinBox. It describes its purpose or indicates the type of value it represents.  

Caption/Description:  

The caption property provides more information or instructions about the SpinBox. It is displayed as a tooltip or a small text box below or beside the SpinBox.  

Value/Current Value:  

The value property represents the current numerical value of the SpinBox. It determines the initial value displayed. It can be modified or through user interaction.  

Minimum/Maximum Value:  

The minimum and maximum define the range of acceptable values. The SpinBox enforces these constraints. It prevents the user from entering values outside the specified range.  

Step/Increment:  

The step property determines the amount by which the SpinBox value changes. It is when the user interacts with the increment or decrement buttons. It represents the increment or decrement value for each step.  

 

The main difference is that widget options for widget styling are no longer present. The Spinbox widget in Tkinter in Python selects a value from the specified range. The Spinbox widget is an alternate to the Entry widget. It is where the user has to enter a numeric value per the user's need but in a specified range. This option is used to indicate the starting range of the widget.  

 

A new selection is created if the selection is not currently in the spinbox. It includes the characters between the index and the recent selection anchor point. Clicking the mouse button positions the insertion cursor before the character under the cursor. It sets the input focus to this widget and clears any selection in the widget.  

 

If the spinbox is read-only, then the value may not be changed. It uses widget commands, and no insertion cursor will be displayed. It is so that even if the input focus is on the widget, its contents may still be selected. In the following ways, an index specifies a character in the spinbox's string. Here we discuss an overview, its Examples, and its Code Implementation.

Dependent Libraries : 
import tkinter as tk
from tkinter import ttk

root = tk.Tk()
root.geometry("300x100")
label = tk.Label(root, text="file type:")
cb = ttk.Combobox(root, values=(".txt", ".doc"), state="readonly", width=8)
label.grid(row=0, column=0)
cb.grid(row=0, column=1)

root.mainloop()

Instructions


Follow the steps carefully to get the output easily..

  1. Copy the snippet using the 'copy' and paste it in your IDE
  2. Install tkinter using pip command : 'pip install tk'
  3. Run the file to generate the output.


I hope you found this useful. I have added version information in the following sections.


I found this code snippet by searching for 'How to create custom spinboxes in Tkinter Python' in kandi. You can try any such use case!

Environment tested


I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in PyCharm 2022.3.3 (Community Edition)
  2. The solution is tested on Python 3.11.1.


Using this solution, we are able to understand how to create custom spinboxes in TKinter python with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us how to create custom spinboxes in TKinter python

                      FAQ:  

                      1. What is the Tkinter Spinbox Widget, and how does it differ from a Tkinter Entry?  

                      Tkinter is a standard GUI library in Python. It allows you to create desktop applications with graphical elements. The Spinbox and Entry are two different widgets Tkinter provides for user input.  

                      Tkinter Spinbox Widget:  

                      The Spinbox widget selects a value from a predefined range of values. It consists of a small box with an up and down arrow on the side and a text field showing the current selected value. The user can either type in the value or use the arrows. It increases or decreases the value within the specified range.  

                       

                      2. How is Python Tkinter used to create spinboxes?  

                      You can use the Spinbox widget to create spinboxes using Python's Tkinter library. The Spinbox widget selects a value by either typing in a value. You can also use increment and decrement buttons to adjust the value.  

                       

                      3. What are the different widget options available with a spinbox?  

                      Graphical user interfaces (GUI), a Spinbox is a widget. It allows users to select a value by typing it or using up and down arrow buttons. It increments or decrements the value. The specific choices may vary depending on the GUI framework you are using. Here are some common options that you might find with a Spinbox:  

                      1. Minimum and Maximum Values.  
                      2. Increment and Decrement Steps.  
                      3. Wraparound.  
                      4. Value Display Format.  
                      5. Validation.  
                      6. Signals and Slots.  
                      7. Read-only Mode.  

                       

                      4. Where is the recent selection anchor point when using a spinbox?  

                      The term "selection anchor point" refers to the position within the spinbox. It is where the selection starts or is anchored. But, it's important to note the concept of a "selection anchor point". It may vary depending on your specific user interface framework or library.  

                       

                      In general, when interacting with a spinbox, the selection anchor point. It is usually set to the current value displayed before the user modifies it. The selection anchor point remains fixed at the initial value as the user interacts.  

                       

                      5. Is there an option to decrement values stored in my spinbox?  

                      Yes, there is an option to decrement the values stored in a spin box. A spin box is a user interface control. It allows users to increment or decrement a numerical value. It clicks up and down arrows or uses keyboard input.  

                       

                      The method for decrementing the value varies depending on your framework. But it provides a way to set the step size and handle incrementing and decrementing actions.
