Python develops a color dynamic two-dimensional code generator in one hour, and uses the virtual environment to package and release the EXE program.

Preface

Beginners Python I learned about this project when I was , It's amazing ！ By calling MyQR The library realizes the synthesis of color two-dimensional codes . I won't introduce this library here , Those interested can search by themselves , There are many related detailed tutorials .

At first, I wanted to share it with my good friends , But I can't write a graphical interface , It has always been in my blog draft box , Today, I can finally write it and share it with you , Super happy ！

The following code explanation is piecemeal , Finally, there is complete code . Including the virtual environment packaging and release at the end of the article EXE Program tutorial editing in graphite document , It's been said in great detail , I don't know. You can talk about me in private .

Core function design

Support .png、.jpg、.gif、.bmp Format conversion , Choose your own materials and pictures .

UI Layout

The program requires few variables , common Three inputs :“ QR code analysis link ”、“ Material name ”、“ Finished product name ”, Because the input box for resolving links is long , So center layout , The rest “ Material name ”、“ Finished product name ” The input field of is short , So the left-right symmetrical layout , In this way, the whole presents “ symmetry 、 Standard Qi ” The effect of .

The material is divided into .png、.jpg、.gif、.bmp Format , use Checkbutton Check the part , Check according to your own material type ！ The image generated in this way is also consistent with the material format type .

On this basis, the design is relatively simple , In addition to the beautification of color , I didn't insert some pictures to decorate , You can carry out secondary development on this basis .

On the design idea of graphical interface

The graphical interface I use is Python Self contained tkinter library , I don't think it's difficult to learn the graphical interface , When you are proficient , You'll find out , He is just one “ window + parts + function ” A process of , The window provides a good basis for our further design “ Containers ”, Components lay the foundation for the functions we realize “ Basics ”, The function is realized by the trigger of the button “ function ”.

Implementation steps （ One ）： Start by building an interface

The interface is like a drawing board , With a drawing board, we can draw on it . besides , We also need to prepare some paint , Only in this way can the painting be colorful , And the interface also has a lot of decoration , For example, the title of the interface 、 Icon 、 These sizes .

from tkinter import *
import tkinter as tk

TOP6 = Tk()# Initialize a window 
TOP6.geometry("575x375")# Set the size for this window 
TOP6.iconbitmap(' Icon .ico')# Specify the window icon 
TOP6.title(' Color dynamic QR code generator V1.0')# Give the window a name 
TOP6.mainloop()# Window loop 
 Copy code 

How to get .ico Format icons ？

stay use Python Write an office gadget for the girl you like , She said it was great ！ In this post , We have explained .

First, choose your favorite picture , And then in Icon online conversion website It can be converted .

As long as the pictures are not too much, they are free .

Implementation steps （ Two ）： Add features to the interface

according to UI Design we need four components ： label （ Describe the data type ）、 Input box （ Receive data ）、Checkbutton Check the part （ Select the material format type ）、 Button （ Trigger function ）.

# QR code analysis link 
label = StringVar()
input_name = Label(TOP6, text=' QR code analysis link ', font=(' Regular script ', 20)).place(x=175, y=20)
entry20 = Entry(TOP6, bg='#ffffff', width=30, textvariable=label, font=(' Regular script ', 20)).place(x=75, y=80)

# Material type options 
var1 = StringVar()
var1.set("F")
c = tk.Checkbutton(TOP6, text=".jpg", variable=var1, onvalue="T", offvalue="F")
c.grid(row=30, column=0, sticky=W)
c.place(x=100, y=125)

var2 = StringVar()
var2.set("F")
c = tk.Checkbutton(TOP6, text=".png", variable=var2, onvalue="T", offvalue="F")
c.grid(row=30, column=0, sticky=W)
c.place(x=200, y=125)

var3 = StringVar()
var3.set("F")
c = tk.Checkbutton(TOP6, text=".gif", variable=var3, onvalue="T", offvalue="F")
c.grid(row=30, column=0, sticky=W)
c.place(x=300, y=125)

var4 = StringVar()
var4.set("F")
c = tk.Checkbutton(TOP6, text=".bmp", variable=var4, onvalue="T", offvalue="F")
c.grid(row=30, column=0, sticky=W)
c.place(x=400, y=125)

# Material name 
label2 = StringVar()
input_name = Label(TOP6, text=' Material name ', font=(' Regular script ', 20)).place(x=35, y=180)
entry20 = Entry(TOP6, bg='#ffffff', width=8, textvariable=label2, font=(' Regular script ', 20)).place(x=25, y=230)

# Finished product name 
label3 = StringVar()
input_name = Label(TOP6, text=' Finished product name ', font=(' Regular script ', 20)).place(x=450, y=180)
entry20 = Entry(TOP6, bg='#ffffff', width=8, textvariable=label3, font=(' Regular script ', 20)).place(x=440, y=230)


# Button 
BUTTON = Button(TOP6, text="(๑¯ิε ¯ิ๑)",width = 15, height = 2,
                    font=(" Regular script ", 15))

BUTTON.place(x=205, y=320)

 Copy code 

Implementation steps （ 3、 ... and ）： Build a function to receive data

Just having an input box is not enough , The meaning of the input box is to receive the required data , So we need to build a function to receive data .

# Receive the value of wechat QR code link 
def get_QR():
    QR = label.get()
    return QR
# Receive material name 
def get_name():
    name = label2.get()
    return name
# Receiving finished product name 
def get_end_name():
    end_name = label3.get()
    return end_name
#.jpg
def get_v1():
    v1 = var1.get()
    return v1
#.png
def get_v2():
    v2 = var2.get()
    return v2
#.gif
def get_v3():
    v3 = var3.get()
    return v3
#.bmp
def get_v4():
    v4 = var4.get()
    return v4
 Copy code 

Implementation steps （ Four ）： Build function function

After receiving the data, we build the function , And pass command Command binding button .

The following code section , We put the received data into the function and call .

Because the material has different formats , The generated finished product should be consistent with the format of the material , So we can divide it into four cases by checking different items , Using simple conditional judgment statements .

There is still a flaw in the design of this function , No successful prompt was generated ！ You can do it yourself and add ！！！！

BUTTON = Button(TOP6, text="(๑¯ิε ¯ิ๑)",width = 15, height = 2,command = QR_Code,
                    font=(" Regular script ", 15))

BUTTON.place(x=205, y=320)
