[Python Practical Skills] Use Python's Tkinter module for GUI programming

foreword

We used Python to update the attributes of song files in batches before, but in order to allow more people to use this tool conveniently, a more friendly graphical interface is needed. For this, I chose to use the Tkinter module to create a simple and easy-to-use graphical interface.

1 Introduction to Tkinter

The tkinter package ("Tk interface") is the standard Python interface to the Tcl/Tk GUI toolkit. Tk and tkinter are available on most Unix platforms, including macOS, and on Windows.
Since Tkinter is built into the python installation package, the Tkinter library can be imported after Python is installed, and IDLE is also written in Tkinter, so Tkinter can handle the simple graphical interface with ease. For detailed instructions, please refer to the official documentation .

2 Tkinter main knowledge

2.1 Tkinter components

Tkinter provides various controls, such as buttons, labels and text boxes, for use in a GUI application. These controls are often referred to as controls or widgets.

There are currently 15 widgets for Tkinter. We present these components along with a short introduction in the table below:

control	describe
Button	Button control; displays a button in a program.
Canvas	Canvas control; displays graphical elements such as lines or text
Checkbutton	Multiple selection box control; used to provide multiple selection boxes in the program
Entry	Input controls; used to display simple text content
Frame	Frame control; display a rectangular area on the screen, mostly used as a container
Label	Label control; can display text and bitmaps
Listbox	Listbox control; the Listbox widget is used to display a list of strings to the user
Menu button	A menu button control, used to display menu items.
Menu	Menu control; display menu bar, drop-down menu and pop-up menu
Message	Message control; used to display multi-line text, similar to label
Radiobutton	Radio button control; displays the state of a radio button
Scale	Range control; displays a numeric scale that limits the range of numeric intervals for output
Scrollbar	A scroll bar control, used when the content exceeds the visible area, such as a list box. .
Text	Text control; used to display multiple lines of text
Toplevel	Container control; used to provide a separate dialog box, similar to Frame
Spinbox	Input control; similar to Entry, but you can specify the input range value
PanedWindow	PanedWindow is a plug-in for window layout management, which can contain one or more sub-controls.
LabelFrame	labelframe is a simple container control. Common and complex window layouts.
tkMessageBox	Used to display message boxes for your application.

2.2 Standard properties

Standard properties are the common properties of all controls, such as size, font and color, and so on.

Attributes	describe
Dimension	control size;
Color	control color;
Font	control font;
Anchor	anchor point;
Relief	control style;
Bitmap	bitmap;
Cursor	cursor;

2.3 Geometry Management

Tkinter controls have a specific geometric state management method to manage the entire control area organization. The following are the geometry management classes exposed by Tkinter: package, grid, position

geometric method	describe
pack()	Package;
grid()	grid;
place()	Location;

3 Tkinter programming

The detailed code implementation is as follows:

import os
import csv
import tkinter as tk
import time
from datetime import datetime
import mutagen
from mutagen.id3 import ID3, TIT2, TPE1, TPE1, TALB, TDRC, TCON


class MusicInfoGUI:
    def __init__(self):
        self.window = tk.Tk()
        self.window.title("音乐信息管理系统")
        self.window.geometry("800x300")

        self.btn1 = tk.Button(self.window, text="1、点击读取当前路径下所有歌曲文件信息", command=self.read_music_files)
        self.btn1.pack(pady=20)

        self.btn2 = tk.Button(self.window, text="2、更新完music.csv后点击修改歌曲属性信息", command=self.update_music_info)
        self.btn2.pack(pady=20)

        self.label = tk.Label(self.window, text="")
        self.label.pack(pady=20)

        self.window.mainloop()

    def read_music_files(self): ... # 代码参考前文
       
    def update_music_info(self):... # 代码参考前文
      

if __name__ == "__main__":
    app = MusicInfoGUI()
