Korvikt [17]

to create a simple notepad in Python using Tkinter. This notepad GUI will consist of various menu like file and edit, using which all functionalities like saving the file, opening a file, editing, cut and paste can be done.

Now for creating this notepad, Python 3 and Tkinter should already be installed in your system. You can download suitable python package as per system requirement. After you have successfully installed python you need to install Tkinter (a Python’s GUI package).

Use this command to install Tkinter :

pip install python-tk

Importing Tkinter :

filter_none

edit

play_arrow

brightness_4

import tkinter

import os

from tkinter import *

# To get the space above for message

from tkinter.messagebox import *

# To get the dialog box to open when required

from tkinter.filedialog import *

Note : messagebox is used to write the message in the white box called notepad and filedialog is used for the dialog box to appear when you are opening file from anywhere in your system or saving your file in a particular position or place.

Adding Menu :

filter_none

edit

play_arrow

brightness_4

# Add controls(widget)

self.__thisTextArea.grid(sticky = N + E + S + W)

# To open new file

self.__thisFileMenu.add_command(label = "New",

command = self.__newFile)

# To open a already existing file

self.__thisFileMenu.add_command(label = "Open",

command = self.__openFile)

# To save current file

self.__thisFileMenu.add_command(label = "Save",

command = self.__saveFile)

# To create a line in the dialog

self.__thisFileMenu.add_separator()

# To terminate

self.__thisFileMenu.add_command(label = "Exit",

command = self.__quitApplication)

self.__thisMenuBar.add_cascade(label = "File",

menu = self.__thisFileMenu)

# To give a feature of cut

self.__thisEditMenu.add_command(label = "Cut",

command = self.__cut)

# To give a feature of copy

self.__thisEditMenu.add_command(label = "Copy",

command = self.__copy)

# To give a feature of paste

self.__thisEditMenu.add_command(label = "Paste",

command = self.__paste)

# To give a feature of editing

self.__thisMenuBar.add_cascade(label = "Edit",

menu = self.__thisEditMenu)

# To create a feature of description of the notepad

self.__thisHelpMenu.add_command(label = "About Notepad",

command = self.__showAbout)

self.__thisMenuBar.add_cascade(label = "Help",

menu = self.__thisHelpMenu)

self.__root.config(menu = self.__thisMenuBar)

self.__thisScrollBar.pack(side = RIGHT, fill = Y)

# Scrollbar will adjust automatically

# according to the content

self.__thisScrollBar.config(command = self.__thisTextArea.yview)

self.__thisTextArea.config(yscrollcommand = self.__thisScrollBar.set)

With this code we will add the menu in the windows of our notepad and will add the things like copy, paste, save etc, to it.
