AttributeError: 'MyPlayer' object has no attribute

[Larz60+]

you import the file, but don't instantiate the MyPlayer class
You write like:

import test
 
class MyPlayer(xbmcgui.WindowXML):
    def __init__(self):
        self.tst = test.MyClass(xbmcgui.WindowXML)

    def UpdateEPG(self):
        self.tst.get_programme_button_width()
