[WxPython] [SOLVED] Simple dialog without app?

[Winfried]

Hello,

Out of curiosity, is it possible to show a simple messagebox without an app instance?

app = wx.App()
wx.MessageBox("text", "title")

Thank you.

No

import wx

wx.MessageBox("text", "title")

Output:
Traceback (most recent call last):
  File "/tmp/tmp.py", line 5, in <module>
    wx.MessageBox("text", "title")
wx._core.PyNoAppError: The wx.App object must be created first!

tkinter can do it

import tkinter as tk
from tkinter import messagebox

def show_message():
    messagebox.showinfo("Greetings", "Hello, World!")

root = tk.Tk()
root.withdraw()  # hide the root window
show_message()

Thanks, but I use wxPython as a GUI.

So I guess the app instance is required.

In every GUI framework you need something that starts the event loop.
In Tkinter that's the main Tk instance, in wxPython it's wx.App

Thanks for the info.
