can we make list (for "popup_menu" and "selection_list") more OOP?

can we make list (for "popup_menu" and "selection_list") in pys60 more object-oriented?

for example:

import appuifw
choices = [u"Symbian",u"PyS60",u"MobileArt"]
index = appuifw.popup_menu (choices,u"Select:")
if index == 0 :
appuifw.note (u"Symbian,aha")
elif index == 1 :
appuifw.note (u"PyS60-yeah")
elif index == 2 :
appuifw.note (u"IloveMobileArt")
#########################################

in script above, we have to make "if statement".
and if we add more item in list "choices", we have to add also the "if statement".

i think that is more near to procedural programming.
can we make it more object-oriented.
for example, if we have 5 item in list, automatically we have 5 "if statement"
and if we have 10 item,automatically we will have 10 "if statement".
without we manually add the "if statement.

can we do that?

Hmph, have you seen a listbox in PyS60?

We can have something like listbox.current()][0] for indicating the selected option.

oh i forget about that.
let me try.

i have tried using Listbox, but i recognize that i have already used UI (appuifw.app.body) CANVAS. so i can't use UI Listbox. is there any other options?

Well, you can change your canvas body to listbox whenever you need. Although you can know the selected item using popup menu too.

Example:

import appuifw

choices = [u"Symbian",u"PyS60",u"MobileArt"]
index = appuifw.popup_menu(choices,u"Select:")

if index != None:
    appuifw.note(choices[index])

Hope it helps,

Rafael.

Although you can know the selected item using popup menu too.

Example:

import appuifw

choices = [u"Symbian",u"PyS60",u"MobileArt"]
index = appuifw.popup_menu(choices,u"Select:")

if index != None:
    appuifw.note(choices[index])

And remember, Python is very powerful manipulator of lists. You can construct a single list containing all the choices and "answers":

choices = [
    (u"Symbian", u"Symbian,aha"),
    (u"PyS60", u"PyS60-yeah"),
    (u"MobileArt", u"IloveMobileArt"),
]
index = appuifw.popup_menu([a[0] for a in choices],
                           u"Select:")
if index != None:
    appuifw.note(choices[index][1])

And of course you can use callable functions too:

def handle_symbian_stuff():
    appuifw.note(u"Symbian,aha")

choices = [
    (u"Symbian", handle_symbian_stuff),
    # [...]
]
index = appuifw.popup_menu([a[0] for a in choices],
                           u"Select:")
if index != None:
    choices[index][1]() # This calls function handle_symbian_stuff
                        # If user selected "Symbian" from popup_menu
