Hello,

I would like to inherit the class listitem, and i have some problem with python

python:


class User(xbmcgui.ListItem):

    def __init__(self, name, label2="", iconImage="", thumbnailImage="", path="", window= None, userdata=None):

        super(User, self).__init__(label=name, label2="", iconImage="", thumbnailImage="", path="")

        self.Base = window

        self.Name = name

        self.UserData = userdata



us = User(msg.username, window = self.Base, userdata= msg.userdata)

Error Message :

python:
TypeError: 'userdata' is an invalid keyword argument for this function

Can help me please ?

Overriding xbmc* classes is a bit tricky because you have to ovverride both __init__ and __new__ methods:

python:
class User(xbmcgui.ListItem):

def __new__(cls, name, label2="", iconImage="", thumbnailImage="", path="", window=None, userdata=None):

    return super(User, cls).__new__(cls, name, label2="", iconImage="", thumbnailImage="", path="")



def __init__(self, name, label2="", iconImage="", thumbnailImage="", path="", window=None, userdata=None):

    super(User, self).__init__(label=name, label2="", iconImage="", thumbnailImage="", path="")

    self.Base = window

    self.Name = name

    self.UserData = userdata

Thank you Roman, its work fine. and have you the solution for convert ListItem to User ?

python:


class User(xbmcgui.ListItem):

    def __new__(cls, name, status =0,  files = 0):

        return super(User, cls).__new__(cls, name)



    def __init__(self, name, status =0,  files = 0):

        super(User, self).__init__(label=name)

        self.Name = name

        self.files = files



    def openSession(self):

       xbmcgui.Dialog().notification('User', self.Name)

       ....

       .....

python:


self.getControl(120).getSelectedItem().openSession()

Error :

python:


AttributeError: 'xbmcgui.ListItem' object has no attribute 'onClick'

If you are not instantiating your ListItem-derived classes by yourslef but receiving ListItem instances from Kodi, then you should use composition instead of inheritance, meaning that you User class should not inherit from ListItem but have a ListItem instance as one of its properties, e.g.:

python:
 class User(object):

  def __init__(self, list_item):

        self._list_item = list_item

       # Access list_item properties via its accessor methods



list_item = window.getControl(120).getSelectedItem()

user = User(list_item)
