Skinning Combobox Component list

I didn’t want to cannibalize absolutezero342’s thread, but I have a similar question:

I’m trying to skin the included ComboBox v3 component, but I haven’t figured out how to skin the list/dropdown or the CellRenderer portion of it. I’ve seen that I can access the dropdown with the ‘dropdown’ property of the ComboBox, but none of my changes ever seem to take.

I’ve also seen that the cellrenderer is treated as a style, but again, I can’t seem to make any changes.

Can someone help?

__dropDown.dropdown.horizontalScrollBar.width = 50;  //does nothing
