Listbox - append()!!!

[v divya]

Hi all,

I now have a query regarding Listbox... I have appended some items into the listbox using append()..

I have used this append() inside another fn add().. But when I print the current item it is always printing the first item in the list..

Y is it like this.. Can someone provide soln for this....

Hi again,

I have added my code here.. The code might not sound professional so kindly bear with it...

import appuifw
import e32

app_lock = e32.Ao_lock()
def quit():
    app_lock.signal()
    appuifw.app.exit_key_handler = quit

def menu():
    global saved
    lb=main()
    fields = [(u"Name",'text',u'')]
    flags = appuifw.FFormEditModeOnly
    saved = False
    def save(arg):
        global saved
        saved = True
        return True
    form = appuifw.Form(fields,flags)
    form.save_hook= save
    form.execute()
    
    if saved == True:
        add = form[0][2]
        DynList.append(add)
    lb = main()
                 
appuifw.app.menu = [(u"Add",menu),(u"Exit",quit)]

DynList = [(u"John")]

def Handle_Selection():
    lb = main()
    appuifw.note(u"Welcome " + DynList[lb.current()])

def main():
    lb = appuifw.Listbox(DynList,Handle_Selection)
    appuifw.app.body = lb
    return lb

main()

app_lock.wait()

When I click on any item in the list (even after adding some items in the list) it always gives "Welcome John"
I am not able to get the current listbox item at all...

What change to make in this sample code to get the current item displayed...

I wasn't able to find the exact problem with that code but it works if you make it less complicated by not making the main function return the Listbox instance:

import appuifw
import e32

app_lock = e32.Ao_lock()
def quit():
    app_lock.signal()
appuifw.app.exit_key_handler = quit

def menu():
    global saved
    fields = [(u"Name",'text',u'')]
    flags = appuifw.FFormEditModeOnly
    saved = False
    def save(arg):
        global saved
        saved = True
        return True
    form = appuifw.Form(fields,flags)
    form.save_hook= save
    form.execute()
    
    if saved == True:
        add = form[0][2]
        DynList.append(add)
    main()
                 
appuifw.app.menu = [(u"Add",menu),(u"Exit",quit)]

def Handle_Selection():
    appuifw.note(u"Welcome " + DynList[lb.current()])

DynList = [(u"John")]

def main():
    global lb
    lb = appuifw.Listbox(DynList,Handle_Selection)
    appuifw.app.body = lb

main()

app_lock.wait()

By the way, you can use the Listbox.set_list(list) method to simply update the entries in the Listbox instead of creating it every time.

Thank u very much bogdan.. But still I would be happy if I get a soln when called from inside a function.. I am using that sort of coding.....
