A System Tray application is created for the continuous execution of the program. Whenever an application is closed by the user, it will get its state running on the taskbar. To identify a system tray application, we can provide an image or icon to its application.To create a System Tray icon of a tkinter application, we can use pystray module in Python. It has many inbuilt functions and methods that can be used to configure the system tray icon of the application.To install pystray in your machine, you can type "pip install pystray" command in your shell or command prompt.To ...

A Label widget is used to display text and images in an application. The size of the label widget depends on a number of factors such as width, height, and Font-size of the Label text. The height and width define how the label widget should appear in the window.To set the width of the label widget, we should declare the Label widget with a variable. Instantiating the label widget with a variable allows the users to add/edit the properties of the Label widget.Example# Import the required libraries from tkinter import * # Create an instance of tkinter frame or ...

Consider a case of running a process in a loop and we want to stop the loop whenever a button is clicked. Generally, in programming languages, to stop a continuous while loop, we use a break statement. However, in Tkinter, in place of the while loop, we use after() to run the defined function in a loop. To break the continuous loop, use a global Boolean variable which can be updated to change the running state of the loop.For the given example, Create a global variable that works similar to the flag in a loop.Define two buttons, Start and Stop, to start and stop the execution.Define ...

Tkinter Text widget is another input widget similar to the Entry widget which accepts multiline user input in a text field. It contains many inbuilt features and functions which helps to configure the default properties of the text widget. However, to add undo/Redo features in the Tkinter text widget, we can use Boolean attributes undo which ensures that the text can be retrieved again.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") # Create a ...

Python supports PIL or Pillow package which is an open-source library for opening, manipulating, and saving different formats of images in Python projects. We can use it in our Tkinter application to process and display images.The Label widget in Tkinter is used to render text and images in a Tkinter application. To display images with Label widget in a Tkinter application, we can follow these steps, Make sure that Pillow or PIL package is installed in your system.Load the image in a variable using ImageTk.PhotoImage(file=file_location) function.Create a Label widget to assign the image value as the image.Execute the code to ...

Tkinter windows are executed after initializing the object of the Tkinter frame or window. We can define the size of the Tkinter window or frame using the Geometry manager. It defines the width and height of the initial Tkinter window where we generally place our widgets. To set the position of the Tkinter window while omitting the width and height, we can define the specification in the geometry manager.Example# Import the required Libraries from tkinter import * from tkinter import ttk # Create an instance of tkinter frame win = Tk() # Set the geometry of tkinter frame ...

Tkinter is a standard Python library that is used to create and develop functional and featured applications. It has a variety of inbuilt functions, modules, and packages that can be used for constructing the logic of the application.The tkFileDialog is an inbuilt module available in the Tkinter library which is useful for interacting with the system files and directories. However, once we select a particular file in the read mode using tkFileDialog, potentially it can be used further to process the information available in the file.If you want to access the absolute path of the file when it gets loaded in ...

To display a large set of data in a Tkinter application, we can use the Treeview widget. Generally, we represent data through tables that contain a set of rows and columns. We can add the data in the form of a table with the help of the Treeview widget.To configure the column width of the Treeview widget, we can use the width and stretch property. It sets the width of the Treeview widget column with the given value.ExampleIn this example, we have created a table that contains a list of programming languages. The width of columns ‘ID’ and ‘Programming Language’ is set ... Read More
In order to create buttons in a Tkinter application, we can use the Button widget. Buttons can be used to process the execution of an event in the runtime of an application. We can create a button by defining the Button(parent, text, **options) constructor.Let us suppose we want to create a Browse Button which when clicked, will ask the user to select a file from the system explorer. To create a dialog box for selecting a file, we can use filedialog package in tkinter library. We can import the filedialog in the notebook using the following command, from tkinter import filedialogOnce the package ... Read More
