Welcome folks today in this post we will be building a qr code generator in tkinter using pyqrcode library. This will be a desktop app in which users will be able to generate qr codes and save it as png image. All the full source code of the application will be given below.
Get Started
In order to get started we need to install the following libraries as shown below with the help of pip command
pip install pyqrcode
pip install tkinter
After installing these libraries you need to make app.py file and copy paste the following code
app.py

from tkinter import * import os import pyqrcode window = Tk() window.title("QR Code Generator") def generate(): if len(Subject.get())!=0 : global qr,photo qr = pyqrcode.create(Subject.get()) photo = BitmapImage(data = qr.xbm(scale=8)) else: messagebox.showinfo("Please Enter some Subject") try: showcode() except: pass def showcode(): imageLabel.config(image = photo) subLabel.config(text="QR of " + Subject.get()) def save(): dir = os.getcwd() + "\\QR Codes" if not os.path.exists(dir): os.makedirs(dir) try: if len(name.get())!=0: qr.png(os.path.join(dir,name.get()+".png"),scale=8) else: messagebox.showinfo("Please enter a File Name") except: messagebox.showinfo("Generate the QR code first!") Sub = Label(window,text="Enter subject") Sub.grid(row =0,column =0,sticky=N+S+W+E) FName = Label(window,text="Enter FileName") FName.grid(row =1,column =0,sticky=N+S+W+E) Subject = StringVar() SubEntry = Entry(window,textvariable = Subject) SubEntry.grid(row =0,column =1,sticky=N+S+W+E) name = StringVar() nameEntry = Entry(window,textvariable = name) nameEntry.grid(row =1,column =1,sticky=N+S+W+E) button = Button(window,text = "Generate",width=15,command = generate) button.grid(row =0,column =3,sticky=N+S+W+E) imageLabel = Label(window) imageLabel.grid(row =2,column =1,sticky=N+S+W+E) subLabel = Label(window,text="") subLabel.grid(row =3,column =1,sticky=N+S+W+E) saveB = Button(window,text="Save as PNG",width=15,command = save) saveB.grid(row =1,column =3,sticky=N+S+W+E) #making this resposnsive Rows = 3 Columns = 3 for row in range(Rows+1): window.grid_rowconfigure(row,weight=1) for col in range(Columns+1): window.grid_columnconfigure(col,weight=1) window.mainloop() |
Now if you execute this python file app.py by executing the below command
python app.py
As you can see in the desktop app we have the option of writing text inside the qr code and then we have the option of the filename of the qr code and then we can generated the qr code and also we have the option to save the image of the qr code as png image
