Hi,
I have a set of functions I use for user management which are common to more than one project except for the very end of some processes which are project specific (aka: "HandleUserLoggedIn" 'event').
So, I have a generic "UserLoginFromEnvironment" (take %username% do some stuff) and then a project-specific "HandleUserLoggedIn" (refresh tables, set some filters, ...)
The way to make this generic in Python would be to pass that function as an argument:
def handle_user_logged_in(user):
print("project specific stuff")
def generic_user_login_from_environment(final_function):
user = os.environ['USERNAME']
final_function(user)
# call the system:
generic_user_login_from_environment(handle_user_logged_in)
NOW, What would be the right approach in WinDev? As far as I've seen, there is no way to pass functions by reference to another function, which prevents the "python way". I also though about events, but there does not seem to be a generic event bus/system available.
Any ideas?
Thanks in advance,
marc |
