Tkinter Programming

Tkinter is Python's standard GUI library. With Python using tkinter, you can quickly create GUI applications.

Since python Tkinter is built into the installation package, then as long as the installed Python can import the tkinter library.

Note: Python3.x version of the library named tkinter, namely T lowercase first letter:

import tkinter
Enter fullscreen mode Exit fullscreen mode

Creating a GUI program

  • import module tkinter
  • create the control
  • specify the control master, that is, what the control belongs to
  • tell GM (geometry manager) that we produced a control

Example:

#!/usr/bin/python

import tkinter
top = tkinter.Tk ()
# Enter the message loop
top.mainloop ()
Enter fullscreen mode Exit fullscreen mode

Code executed above, results are as follows:

tkinter window

Example 2:

#!/usr/bin/python
# - * - coding: UTF-8 - * -

from tkinter import * # import Tkinter library
root = Tk () # create window object background color

# Create two lists
li = [ 'C', 'python', 'php', 'html', 'SQL', 'java']
movie = [ 'CSS', 'jQuery', 'Bootstrap']
listb = Listbox (root) # create two lists components
listb2 = Listbox (root)
for item in li: # first small data insertion member
    listb.insert (0, item)

for item in movie: # inserting the second widget data
    listb2.insert (0, item)

listb.pack () # widget is placed into the main window
listb2.pack ()
root.mainloop () # enter the message loop
Enter fullscreen mode Exit fullscreen mode

Code executes above, results are as follows:

tkinter window listbox
