How exactly do you use styleclasses ?

I did try to understand how to change the font style of a combo-box !

I see that the code :
B4X: 
    For i=0 To varspin.StyleClasses.Size-1   
    Log("style: "&varspin.StyleClasses.Get(i))
    Next
returns 2 results : combo-box and combo-box-base which are substructures of combo-box

How do I reference the label ..of substructure in order to modify font ? and other things ..
Thanks

In the java fx scene bulder I tried to add a calss name "label" then set the combo-box style with -fx-font-size: 12 ;

the below statement does not work on b4j
varspin.StyleClasses.Add("label") '???? from another planet
varspin.Style= "-fx-font-size: 12 ;"
