Introduction to Tkinter
Tkinter is the standard GUI library in Python programming language. It is one of the most commonly used library for creating GUI applications using Python. Tkinter provides a powerful object-oriented interface for creating GUI programs.
Syntax
The basic syntax of Tkinter is as follows:
import tkinter as tk
window = tk.Tk()
Here import tkinter
imports the module tkinter
for GUI programming, and window = tk.Tk()
creates a main window object for your application.
Example
Here is a simple code example that creates a main window with a label widget:
import tkinter as tk
window = tk.Tk() # Create main window object
window.title("Welcome to Tkinter") # Set window title
label = tk.Label(window, text="Hello World!") # Create label widget
label.pack()
window.mainloop() # Start the event loop
When the above code is executed, a main window with a label widget containing the text "Hello World!" will be displayed.
Explanation
In the above code, tk.Label()
creates a label widget with the text "Hello World!" in it. The pack()
method packs the label widget into the window.
window.mainloop()
starts the window's event loop, which waits for events like button clicks or mouse movements.
Use
Tkinter can be used to create desktop applications with a graphical user interface. It offers a large variety of widgets such as buttons, labels, textboxes, menus and more. It also allows you to control the appearance and layout of your application using various options available.
Important Points
- Tkinter works with the concept of widgets.
- There are many different widgets available in Tkinter for building GUIs.
mainloop()
function is used to start the event loop of the window.- We can control the positioning of the widgets using various methods such as
pack()
,grid()
, andplace()
. - Tkinter provides
StringVar()
,IntVar()
andBooleanVar()
classes for creating variables that can be used in our application.
Summary
Tkinter is a popular GUI library in Python programming language. It provides an object-oriented interface to create GUI applications. It can be used to create different types of widgets like buttons, labels, textboxes, menus and more. It also provides several options for styling and arranging widgets in the window.
