How to Make Notepad by Using Python Tkinter

In this Python tkinter tutorial, how to make notepad by using Python Tkinter and we will also cover the different examples related to the Python tkinter. Besides this, we will also cover the whole code related to How to make notepad by using python tkinter.

How to Make Notepad by Using Python Tkinter

Notepad is used as a simple text editor it can build and corrects the plain text documents. The notepad is also known as a sheet of a paper that are used for written the things.

Block of Code:

In this block of code we importing the tkinter library such as import tkinter, import os, from tkinter import *, import tkinter.messagebox import *, from tkinter.filedialog import *.

# How to make notepad by using Python Tkinter
import tkinter
import os   
from tkinter import *
from tkinter.messagebox import *
from tkinter.filedialog import *

Block of Code:

In this block of code we are creating the window and also giving the width and height to the window and then creating the text area and menu bar and after that we are creating the menu bar .

 
    root = Tk()
    
    # default window width and height
    width = 600
    height = 400
    textarea = Text(root)
    menubar = Menu(root)
    filemenu = Menu(menubar, tearoff=0)
    editmenu = Menu(menubar, tearoff=0)
    helpmenu = Menu(menubar, tearoff=0)

Block of Code:

In this block of code we are adding the scrollbar by using scrollbar() method and also defining the init function.

# To add scrollbar
    scrollbar = Scrollbar(textarea)    
    file = None
 
    def __init__(self,**kwargs):
 
        # Set icon
        try:
                self.root.wm_iconbitmap("Notepad.ico")
        except:
                pass

Block of code:

In this block of code we will set the window size and then we will set the window text and after that we are creating the window and then we are making the text area resizeable and after that creating a feature of description of the notepad after that adjust Scrollbar automatically according to the content.

# Set window size
 
        try:
            self.width = kwargs['width']
        except KeyError:
            pass
 
        try:
            self.height = kwargs['height']
        except KeyError:
            pass
 
        # Set the window text
        self.root.title("Untitled - Notepad")
 
        # Center the window
        screenWidth = self.root.winfo_screenwidth()
        screenHeight = self.root.winfo_screenheight()
     
        # For left-align
        left = (screenWidth / 2) - (self.width / 2)
         
        # For right-align
        top = (screenHeight / 2) - (self.height /2)
         
        # For top and bottom
        self.root.geometry('%dx%d+%d+%d' % (self.width,
                                              self.height,
                                              left, top))
 
        # To make the textarea auto resizable
        self.root.grid_rowconfigure(0, weight=1)
        self.root.grid_columnconfigure(0, weight=1)
 
        # Add controls (widget)
        self.textarea.grid(sticky = N + E + S + W)
         
        # To open new file
        self.filemenu.add_command(label="New",
                                        command=self.newfile)   
         
        # To open a already existing file
        self.filemenu.add_command(label="Open",
                                        command=self.openfile)
         
        # To save current file
        self.filemenu.add_command(label="Save",
                                        command=self.savefile)   
 
        # To create a line in the dialog      
        self.filemenu.add_separator()                                        
        self.filemenu.add_command(label="Exit",
                                        command=self.quitapplication)
        self.menubar.add_cascade(label="File",
                                       menu=self.filemenu)    
         
        # To give a feature of cut
        self.editmenu.add_command(label="Cut",
                                        command=self.cut)            
     
        # to give a feature of copy    
           self.editmenu.add_command(label="Copy",
                                        command=self.copy)        
         
        # To give a feature of paste
        self.editmenu.add_command(label="Paste",
                                        command=self.paste)        
         
        # To give a feature of editing
        self.menubar.add_cascade(label="Edit",
                                       menu=self.editmenu)    
         
        # To create a feature of description of the notepad
        self.helpmenu.add_command(label="About Notepad",
                                        command=self.showabout)
        self.menubar.add_cascade(label="Help",
                                       menu=self.helpmenu)
 
        self.root.config(menu=self.menubar)
 
        self.scrollbar.pack(side=RIGHT,fill=Y)                   
         
        # Scrollbar will adjust automatically according to the content       
        self.scrollbar.config(command=self.textarea.yview)    
        self.textarea.config(yscrollcommand=self.scrollbar.set)

Block of code:

In this block of code we will defining the quit application and then defining the show about after that defining the open file.

def quitapplication(self):
        self.root.destroy()
        # exit()
 
    def showabout(self):
        showinfo("Notepad","Mrinal Verma")
 
    def openfile(self):
         
        self.file = askopenfilename(defaultextension=".txt",
                                      filetypes=[("All Files","*.*"),
                                        ("Text Documents","*.txt")])
 
        if self.file == "":
             
            # no file to open
            self.file = None
        else:
             
            # Try to open the file
            # set the window title
            self.root.title(os.path.basename(self.file) + " - Notepad")
            self.textarea.delete(1.0,END)
 
            file = open(self.file,"r")
 
            self.textarea.insert(1.0,file.read())
 
            file.close()

Block of code:

In this block of code we will defining the new file function and then we will defining the save file function and after that defining cut, copy, paste, and run function.

def newfile(self):
        self.root.title("Untitled - Notepad")
        self.file = None
        self.textarea.delete(1.0,END)
 
    def savefile(self):
 
        if self.file == None:
            # Save as new file
            self.file = asksaveasfilename(initialfile='Untitled.txt',
                                            defaultextension=".txt",
                                            filetypes=[("All Files","*.*"),

            if self.file == "":
                self.file = None
            else:
                # Try to save the file
                file = open(self.file,"w")
                file.write(self.textarea.get(1.0,END))
                file.close()
                 
                # Change the window title
                self.root.title(os.path.basename(self.file) + " - Notepad")
                 
             
        else:
            file = open(self.file,"w")
            file.write(self.textarea.get(1.0,END))
            file.close()
 
    def cut(self):
        self.textarea.event_generate("<<Cut>>")

# Run main application
notepad = Notepad(width=600,height=400)
notepad.run()

Code:

Hereafter splitting the code and explaining how to make Notepad by using in Python Tkinter, now we will see how the output look like after running the whole code.

        self.root.mainloop()
 
 
 
 
# Run main application
notepad = Notepad(width=600,height=400)
notepad.run()

Output:

After running the whole code we get the following output in which we can see that the notepad is created on the screen with the help of Python Tkinter on the screen.

So, in this tutorial, we have illustrated How to make notepad by using Python Tkinter. Moreover, we have also discussed the whole code used in this tutorial.
