While building an application with Tkinter, we can use many components and widgets to extend the application. To render the widgets in the application, we use the Geometry Manager.The geometry manager configures the widget position and size within the window. The Grid Geometry manager treats the widget to place in rows and columns.If we want to span the widget and extend in one more cell or column, we use widget.rowconfigure() or widget.grid_rowconfigure(). It takes params such as weight and row/col value.The widget.rowconfigure() is sometimes used in place of widget.grid_rowconfigure(). Using these methods will allow the widget to have a weight property ... Read More

Python has many inbuilt libraries and modules that are used for building various application interfaces and components. Pygame is one of the python modules which is used to design and build video games and music. It provides a mixture to handle all sound related activities. Using music sub-module, you can stream mp3, ogg, and other variety of sounds.To create an application that plays some sound on clicking a button, we have to follow these steps, Make sure that Pygame is installed in your local machine. You can install pygame using pip install pygame command.Initialize Pygame mixture by using pygame.mixture.init()Create a button widget which is ... Read More

A Button widget in Tkinter has many inbuilt features which can be used to configure and perform a certain task in the application. In order to run a particular event in the application, we can use the bind("", callback) method to bind a function or event with the button. To add the hover property in the Button, we can use and parameters in the bind function.Example# Import the required libraries from tkinter import * from tkinter import ttk # Create an instance of tkinter frame or window win=Tk() # Set the size of the window win.geometry("700x350") def change_bgcolor(e): ...

For a particular application, if we want to perform multiple tasks with the help of buttons defined in it, then we can use the bind(Button, callback) method which binds the button and the event together to schedule the running of the event in the application.Let us suppose we want to bind multiple events or callback with a single , then we have to first iterate over all the widgets to get it as one entity. The entity can be now configurable to bind the multiple widgets in the application.Example# Import the required libraries from tkinter import * from tkinter import ... Read More

An Excel Spreadsheet contains a set of information stored in the form of rows and columns. We can display and use the spreadsheet data in the Tkinter application using Treeview widget. The Treeview widget in Tkinter helps users to add and manipulate the data in the form of a table. However, to analyze and manipulate a large set of data, Python provides Pandas library which gives access to many inbuilt functions and methods to perform data analysis.For this example, we will follow these steps to display the Excel Data in Tkinter, Import the required Libraries such as Numpy, Pandas, and filedialog.Add a ...

Generally, we represent data in the form of tables. A table contains a set of rows and columns. Data gets stored sequentially in the form of rows and columns in a table.Let us suppose that we are building a Tkinter application such that we have to store the Student’s data somewhere in a table. The table structure contains 3 columns to store the First Name, Last Name, and Roll Number of students. To display this type of information, Tkinter provides a Notebook widget where we can store our data in the form of a Table.Example# Import the required libraries from tkinter ... Read More

To create a tkinter window without title bar, we can use overrideredirect(boolean) property which disables the navigation panel from the top of the tkinter window. However, it doesn’t allow the user to resize the window instantly.If we are required to create a resizable window without the title bar programmatically, then we can use Sizegrip(parent) widget in Tkinter. The Sizegrip widget adds extendibility to the application that allows users to pull and resize the main window. To work with Sizegrip widget, we have to Bind the mouse buttons and a function that resizes the window whenever we pull the grip.Example# Import the required ... Read More

Buttons are a very useful widget in any Tkinter application. We can get the value of any button in the Entry widget by defining the function which inserts the value in the Entry widget. To get the value, we have to first define buttons having command for adding the specific value to be displayed on the Entry widget.To update the Entry widget, we can delete the previous value using delete(0, END) method.Example# Import the required libraries from tkinter import * from tkinter import ttk # Create an instance of tkinter frame or window win=Tk() # Set the size of ...

In most cases, you need to have several screens to allow the user to switch between different segments of your program. One way to achieve this is to create separate frames that lie inside the main window.A-Frame widget is used to group too many widgets in the application. We can add separate widgets in two different frames. The user can switch to the frame from one to another by clicking the button.ExampleIn this application, we will create two separate frames greet frame and order frame. Each frame consists of two different objects. A Button will be used to switch between ... Read More

Python has a rich library of modules and functions that allows us to build and develop featured applications. Tkinter is a well-known Python library that is used for creating GUIbased applications. If we want to develop an application that takes a screenshot of the window, then we can definitely use Tkinter to build the GUI of the application. The following stages of the application will help to know how our application works, Required Libraries – Pillow (PIL) for Image Processing, Time Module in Python for Randomizing the Filename and epochs processing.Create a Label widget in the window and add a ...
