Tkinter is a Python binding to the Tk GUI toolkit. It is the standard Python interface to the Tk GUI toolkit, and is Python's de facto standard GUI. Tkinter is included with standard Linux, Microsoft Windows and macOS installs of Python.
The name Tkinter comes from Tk interface. Tkinter was written by Steen Lumholt and Guido van Rossum, then later revised by Fredrik Lundh.
Tkinter is free software released under a Python license.
As with most other modern Tk bindings, Tkinter is implemented as a Python wrapper around a complete Tcl interpreter embedded in the Python interpreter. Tkinter calls are translated into Tcl commands, which are fed to this embedded interpreter, thus making it possible to mix Python and Tcl in a single application.
There are several popular GUI library alternatives available, such as Kivy, Pygame, Pyglet, PyGObject, PyQt, PySide, and wxPython.
This term has different meanings in different contexts, but in general it refers to a rectangular area somewhere on the user's display screen.
A window which acts as a child of the primary window. It will be decorated with the standard frame and controls for the desktop manager. It can be moved around the desktop and can usually be resized.
The generic term for any of the building blocks that make up an application in a graphical user interface.
In Tkinter, the Frame widget is the basic unit of organization for complex layouts. A frame is a rectangular area that can contain other widgets.
When any widget is created, a parent–child relationship is created. For example, if you place a text label inside a frame, the frame is the parent of the label.
Here is a minimal Python 3 Tkinter application with one widget:
#!/usr/bin/env python3 from tkinter import * root = Tk() # Create the root (base) window w = Label(root, text="Hello, world!") # Create a label with words w.pack() # Put the label into the window root.mainloop() # Start the event loop
For Python 2, the only difference is the word "tkinter" in the import command will be capitalized to "Tkinter".
There are four stages to creating a widget
These are often compressed, and the order can vary.
Using the object-oriented paradigm in Python, a simple program would be (requires Tcl version 8.6, which is not used by Python on MacOS by default):
#!/usr/bin/env python3 import tkinter as tk class Application(tk.Frame): def __init__(self, root=None): tk.Frame.__init__(self, root) self.grid() self.createWidgets() def createWidgets(self): self.medialLabel = tk.Label(self, text='Hello World') self.medialLabel.config(bg="#00ffff") self.medialLabel.grid() self.quitButton = tk.Button(self, text='Quit', command=self.quit) self.quitButton.grid() app = Application() app.root.title('Sample application') app.mainloop()
