You can set the position of a text widget by specifying its dimension using place(**option) geometry manager. Instantiating a widget inside a frame makes the widget independent throughout the application window. We then use the place()geometry manager to assign the width and height of the widget inside the window. The pixels justify how accurately a widget is positioned in the window. Thus, the place() geometry manager provides a grid system where we can place any widget in a particular location.Example# Import required libraries from tkinter import * from tkinter import ttk from lorem_text import lorem # Create an instance ...

Python Matplotlib library is helpful in many applications for visualizing the given data and information in terms of graphs and plots. It is possible to run matplotlib in a Tkinter application. Generally, importing any Python library explicitly in an application gives access to all its functions and modules in the library.To create a GUI application that uses matplotlib and its functions, we have to import the library using the command from matplotlib.pyplot as plt. However, we also use Tkagg in the backend that uses the Tkinter user interface interactively.ExampleIn this example, we have imported Tkagg and matplotlib to visualize the ... Read More
Python Tkinter is a standard library that is used to develop GUI-based featured and functional applications. Whenever we execute our application, it displays a general window that contains some widgets and a title bar in it. The mainloop() method is responsible for executing the script and displaying the output window. However, mainloop() implies that it doesn't terminate automatically until the user remains in the window. Whenever the user terminates the program, it gets closed automatically. The mainloop() method gets called whenever the program starts executing.Example# Import the required libraries from tkinter import * # Create an instance of tkinter ... Read More
Tkinter provides Text widget to input data in a text field. It can accept multiline user input. Tkinter includes many inbuilt properties and features that can be used to improve the look and feel of the context. The text written in Text widget can be wrapped with wrap property. The wrap allows users to simplify the text editor by wrapping the context in words, characters or None. It fixes the indentation of the text inside the Text Editor.ExampleIn this example, we will wrap the sentences by words which means each word gets selected automatically without following the same line.# Import ...

Tkinter is a well-known Python library for creating GUI-based applications. You can create a fully featured application with the help of widgets, functions, and modules that are already present in Tkinter library.Sometimes, selecting the right GUI of the application becomes a daunting task for many of us. Tkinter comes with a set of inbuilt functions and extensions to create good-looking GUIs.Generally, the Frame widget in Tkinter manages all the widgets in an application as a container. It inherits all the properties that the main window can contain. To design the layout of the widgets, we can use any of the ... Read More
Tkinter Events are generally used to provide an interface that works as a bridge between the User and the application logic. We can use Events in any Tkinter application to make it more interactive and functional. Events like and are used to call a specific function only when a key is pressed or released.ExampleIn this example, we will create a script that will show some message on the screen whenever we press a key. The message gets disappeared when we release the same key.# Import the Required libraries from tkinter import * # Create an instance of ... Read More
Tkinter is a Python library which is used to create GUI-based application. Tkinter comes with many inbuilt features and extensions which can be used to optimize the application performance and behaviour. Tkinter Events are generally used to provide an interface that works as a bridge between the User and the application logic. We can use Events in any Tkinter application to make it operable and functional.Here is a list of some common Tkinter events which are generally used for making the application interactive. − Use the Button event in a handler for binding the Mouse wheels and Buttons. − Instead ...

Tkinter Combobox widget is one of the useful widgets to implement dropdown menus in an application. It uses the combination of the Entry widget and ListBox widget on the top of it. We can select Menu items by typing the item name (if it exists in the Menu List) in the Entry field. However, sometimes, there might be cases when we need to use autocompletion to select the menu items.In order to create an auto-completion Combobox, we will create a Listbox first to list out the menus and an Entry widget to display the selected Menu. You can bind the ... Read More
Tkinter has lots of inbuilt functions and methods that can be used configure the properties of Tkinter widgets. These properties vary with different geometry managers. The grid geometry manager is one of them which deals with many complex layout problems in any application. Grid geometry manager adds all the widgets in the given space (if applicable) without overlapping each other.Let us suppose that we have created a sticky frame using Grid geometry manager and we want to center the Label text widget inside the frame. In this case, we have to first make the main window sticky by configuring the ... Read More
The margin of a tkinter window can be controlled by specifying the value of fill, expand and padding. Another way to set the margin of a tkinter window is to use grid(**options) Geometry Manager. Grid pack manager allows us to add the margin by specifying the value of row and column property.Example# Import the required library from tkinter import * from tkinter import ttk # Create an instance of tkinter frame win= Tk() # Set the size of the Tkinter window win.geometry("700x350") # Add a frame to set the size of the window frame= Frame(win, relief= 'sunken', ...
