Welcome folks today in this blog post we will be building a sticky notes desktop app in tkinter using python. All the full source code of the application is shown below.

Get Started

In order to get started you need to make an app.py file and copy paste the following code

app.py

from tkinter import *
import tkinter.scrolledtext as tkst
from tkinter import messagebox
from tkinter import font 
no_of_windows = 1


class StickyNotes(Toplevel):
    def __init__(self, master, **kwargs):
        super().__init__(master, **kwargs)
        self.xclick = 0
        self.yclick = 0

        # master (root) window
        self.overrideredirect(True)
        global no_of_windows
        self.geometry('250x250+' + str(1000+no_of_windows*(-30)) + '+' + str(100 + no_of_windows*20))
        self.config(bg = '#838383')
        self.attributes('-topmost', 'true')
        self.resizable(True,True)

        # titlebar
        self.titlebar = Frame(self, bg = '#F8F796', relief = 'flat', bd = 2)
        self.titlebar.bind('<Button-1>', self.get_pos)
        self.titlebar.bind('<B1-Motion>', self.move_window)
        self.titlebar.pack(fill = X, expand = 1, side = TOP)

        self.closebutton = Label(self.titlebar, text = 'X', bg = '#F8F7B6', relief = 'flat')
        self.closebutton.bind('<Button-1>', self.quit_window)
        self.closebutton.pack(side = RIGHT)

        self.newbutton = Label(self.titlebar, text = '+', bg = '#F8F7B6', relief = 'flat')
        self.newbutton.pack(side = LEFT)
        self.newbutton.bind('<Button-1>', self.another_window)

        # main text area
        self.mainarea = tkst.ScrolledText(self, bg = '#FDFDCA', font=('Comic Sans MS', 14, 'italic'), relief = 'flat', padx = 5, pady = 10)
        self.mainarea.pack(fill = BOTH, expand = 1)

        # frames to introduce shadows
        self.shadow = Frame(self).pack(side=BOTTOM)
        self.shadow = Frame(self).pack(side=RIGHT)
        
        no_of_windows += 1

    def get_pos(self, event):
        self.xclick = event.x
        self.yclick = event.y

    def move_window(self, event):
        self.geometry('+{0}+{1}'.format(event.x_root-self.xclick, event.y_root-self.yclick))

    def another_window(self, event):
        sticky = StickyNotes(root)

    def quit_window(self, event):
        self.closebutton.config(relief = 'flat', bd = 0)
        if(messagebox.askyesno('Delete Note?','Are you sure you want to delete this note?', parent = self)):
            global no_of_windows
            self.destroy()
            no_of_windows -= 1
            if(no_of_windows == 1):
                root.destroy()
            return
        self.closebutton.config(relief = 'flat', bd = 0, bg = '#F8F7B6')

root = Tk()
root.withdraw()
# make the first note.
sticky = StickyNotes(root) 
root.mainloop()

Now if you execute the above python script by typing the below command as shown below

python app.py
