Hi i am writing a plugin for my Dreambox One UltraHD

and plugin runs fine but my problem is that i get this error:

AttributeError: 'eListbox' object has no attribute 'setFont'

How do i add my custom font to the widget "menu"

Here is the skin code and i have highlighted whats making my plugin crash
If i remove this font="jediregular;36" then all works fine but i want my custom font in the menu

<widget name="menu" position="519,309" size="892,672" font="jediregular;36" foregroundColor="#ffffff" backgroundColor="#000000"
foregroundColorSelected="#ffffff" backgroundColorSelected="#000000" selectionPixmap="/usr/lib/enigma2/python/Plugins/Extensions/JediMakerXtream/skin/fhd/default/images/select-892-56.png"
itemHeight="56" scrollbarMode="showOnDemand" transparent="1" zPosition="2" />
