Alert boxes in Python?

Start an app as a background process that either has a TCP port bound to localhost, or communicates through a file — your daemon has the file open, and then you echo "foo" > c:yourfile. After, say, 1 second of no activity, you display the message and truncate the file.

You can use win32 library in Python, this is classical example of OK or Cancel.

import win32api
import win32com.client
import pythoncom

result = win32api.MessageBox(None,"Do you want to open a file?", "title",1)

if result == 1:
 print 'Ok'
elif result == 2:
 print 'cancel'

The collection:

win32api.MessageBox(0,"msgbox", "title")
win32api.MessageBox(0,"ok cancel?", "title",1)
win32api.MessageBox(0,"abort retry ignore?", "title",2)
win32api.MessageBox(0,"yes no cancel?", "title",3)

GTK may be a better option, as it is cross-platform. It’ll work great on Ubuntu, and should work just fine on Windows when GTK and Python bindings are installed.

from gi.repository import Gtk

dialog = Gtk.MessageDialog(None, 0, Gtk.MessageType.INFO,
            Gtk.ButtonsType.OK, "This is an INFO MessageDialog")
dialog.format_secondary_text(
    "And this is the secondary text that explains things.")
dialog.run()
print "INFO dialog closed"

You can see other examples here. (pdf)

The arguments passed should be the gtk.window parent (or None), DestroyWithParent, Message type, Message-buttons, title.

For those of us looking for a purely Python option that doesn’t interface with Windows and is platform independent, I went for the option listed on the following website:

https://pythonspot.com/tk-message-box/ (archived link: https://archive.ph/JNuvx)

# Python 3.x code
# Imports
import tkinter
from tkinter import messagebox

# This code is to hide the main tkinter window
root = tkinter.Tk()
root.withdraw()

# Message Box
messagebox.showinfo("Title", "Message")

You can choose to show various types of messagebox options for different scenarios:

• showinfo()
• showwarning()
• showerror ()
• askquestion()
• askokcancel()
• askyesno ()
• askretrycancel ()

You can use PyAutoGui to make alert boxes
First install pyautogui with pip:

pip install pyautogui

Then type this in python:

import pyautogui as pag
pag.alert(text="Hello World", title="The Hello World Box")

Here are more message boxes, stolen from Javascript:

• confirm()
  With Ok and Cancel Button
• prompt()
  With Text Input
• password()
  With Text Input, but typed characters will be appeared as *
