# This module contains all the Windows-specific code to create native
# message boxes using the winapi.

# If you'd like to learn more about calling the winapi functions from
# Python, you can check out my other module "nicewin" to see nicely-documented
# examples. It is at https://github.com/asweigart/nicewin

# The documentation for the MessageBox winapi is at:
# https://docs.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-messagebox
