2.0.2. Simple Offline-Capable Note Taking Application Tutorial

1. Step 1: Setting Up
   

   First, you'll need to create a new Python file and import the necessary modules.

   ```Python import sqlite3 from tkinter import * ```

2. Step 2: Set up SQLite Database
   

   Next, connect to SQLite and create a table to store notes.

   ```Python conn = sqlite3.connect('notes.db')

   c = conn.cursor()

   c.execute("""CREATE TABLE notes ( title text, note text )""")

   conn.commit() conn.close() ```

3. Step 3: Create UI with tkinter
   

   Create a simple UI for adding and viewing notes.

   ```Python root = Tk()

   title<sub>label</sub> = Label(root, text='Title') title<sub>label.pack</sub>() title<sub>entry</sub> = Entry(root) title<sub>entry.pack</sub>()

   note<sub>label</sub> = Label(root, text='Note') note<sub>label.pack</sub>() note<sub>text</sub> = Text(root) note<sub>text.pack</sub>()

   def add<sub>note</sub>(): conn = sqlite3.connect('notes.db') c = conn.cursor() c.execute("INSERT INTO notes VALUES (:title, :note)", { 'title': title<sub>entry.get</sub>(), 'note': note<sub>text.get</sub>("1.0", END) }) conn.commit() conn.close()

   add<sub>button</sub> = Button(root, text='Add note', command=add<sub>note</sub>) add<sub>button.pack</sub>()

   root.mainloop() ```

   This basic TKinter UI consists of two text entry fields for the note's title and text, and a button to add the note.

4. Step 4: View Notes
   

   The final step is adding a function to view existing notes. Add this code to create a new button and function:

   ```Python def view<sub>notes</sub>(): conn = sqlite3.connect('notes.db') c = conn.cursor() c.execute("SELECT *, oid FROM notes") records = c.fetchall()

   print<sub>records</sub> = ''

   for record in records: print<sub>records</sub> += str(record[0]) + " " + "\t" + str(record[1]) + "\n"

   query<sub>label</sub> = Label(root, text=print<sub>records</sub>) query<sub>label.pack</sub>()

   conn.commit() conn.close()

   view<sub>button</sub> = Button(root, text='View notes', command=view<sub>notes</sub>) view<sub>button.pack</sub>() ```

   This concludes the basic tutorial of creating an offline-capable note-taking application using Python and SQLite. For full application, you might want to add options to edit and delete notes and add a better user interface. You can also incorporate error handling and further testing for robustness.
