Hi!

I'm pretty new to programming and I'm working on an addon.
My addon processes the user input from several "Edit"-s (xbmcgui.ControlEdit), and it has to make sure, none of the "Edit"-s are empty, before calling a function.

I've tried it two ways, both of them were working, but which is the right way to implement it?

The addon should notify the user and terminate the execution without closing the window, so the user can try again.

First I've tried it without catching the Exception:

PHP Code:
import xbmcgui

dialog = xbmcgui.Dialog()

class EmptyEditException(Exception):
    def __init__(self):
        msg = "Some edits are empty."
        xbmc.log(msg)
        dialog.notification("Alert", msg)

def check_if_empty(s):
    if s == "":
        raise EmptyEditException

edit0 = xbmcgui.ControlEdit (100, 250, 125, 75, 'Status')

def some_function():
    input = edit0.getText()
    check_if_empty(input)
    some_other_func(input) 

So the execution will be terminated, because of the exception.

The other way:

PHP Code:
import xbmcgui

dialog = xbmcgui.Dialog()

class EmptyEditException(Exception):
    def __init__(self):
        msg = "Some edits are empty."
        xbmc.log(msg)

def check_if_empty(s):
    if s == "":
        raise EmptyEditException

edit0 = xbmcgui.ControlEdit (100, 250, 125, 75, 'Status')

def some_function():
    input = edit0.getText()
    check_if_empty(input)
    some_other_func(input)

def button_handler():
    try:
        some_function()
    except EmptyEditException:
        dialog.notification("Alert", "Fill all the edits!") 

How would you implement it?

Thanks!

if you use doModal() to show your window, it won't auto-close when the script ends.
your addon will have to explicitly call close() in order to close the window.

Thanks for the reply!

I do use doModal() (maybe I should have posted the full code), both of my examples work, I only want to know, which one is the right, or the better way to do it.

The first one lets the Exception happen, the second one catches it and creates a notification.

i think i would do it like this (as i see no need for try / except / raise)

Code:
def some_function():

    input = edit0.getText()

    if input:

        some_other_func(input)

        return True

def button_handler():

    succes = some_function()

    if not success:

        dialog.notification("Alert", "Fill all the edits!")

Thank you so much!
This is way more simple than my solution.
