The last time I raised a question is how to achieve ScrollBar automatic scrolling (), after unremitting efforts finally solved the problem! Worth Celebrating ~ ~ ~Not many words, the programmer or the last code comparison is real!

The example in this article shows the Python Tkinter method for implementing a simple layout, with a more detailed annotation for the reader to understand. Share for everyone to use for reference. as follows: #-*-Coding:utf-8-*-from tkinter import * root = Tk () # 80x80 represents the size of the main window at initialization time, 0, 0 represents the location of the window at initialization root.geom

we have said enough in front of us, and we will do the example procedure in the following time. first, let's look at a nice little program: Example 2-1. Our first Tkinter program # File:hello1.py from tkinter import * root = Tk () w = Label (Root, text= "Hello, world!") W.pack () Root.mainloop () Run Run on the command line as follows: $ python hello1.py The following window will

There's a basic understanding of Python, always want to do something have been struggling to find a good practice, this does not work, need to do the project plan, the project needs to be based on 3 known parameters to calculate other parameters, as well as the stability of the parameters of the state, so intend to use this to familiarize yourself with Python, Although this program is not very robust, and did not encapsulate the parameters, but let me basically familiar with the

Mainly based on the Colorsys implementation, the example is from HLS to RGB, if you want to change the color space very easy only need to change a functionScale and canvas components are usedThe code is as follows:from Tkinter import *import colorsys# operation response Function def update (* args): ' color ' r,g,b = col Orsys.hls_to_rgb (H.get ()/255.0, L.get ()/255.0, S.get ()/255.0) R,g,b = R * 255, G * 255, B * 255 rgb.configure ( Text = ' RGB: (%

In this paper, the Tkinter of Python development is introduced to realize the method of moving the graph with mouse. Share to everyone for your reference, as follows: When you do this, the inspiration comes from a JS effect: Two eyes move with mouse movement Operating effect: Code section: From tkinter Import * #1. Gets the current center coordinate of the small circle (x1, y1) #2. Gets the center coordin

This example shows a simple chat window for a Python tkinter layout. Share it for everyone's reference. Here's how: This example shows a simple chat window, can be implemented below the input chat content, click Send, can be added to the above chat record list. Now it's just a "stand-alone" version.There is a vacancy on the right to put something else. Interested readers can further make the sockets to chat with each other. Here is the function code
