Perspective Tab Container - tabStyle and style classes

The documentation says that for a Tab Container, for ‘tabStyle’, for both ‘active’ and ‘inactive’ that a ‘style class’ can be specified.

https://docs.inductiveautomation.com/display/DOC80/Perspective+-+Tab+Container

I’ve been unable to figure out how to get a class to apply here. I can set props directly for each, like ‘color’, etc. but not a style class.

Any help would be appreciated.

Thanks.

Figured it out. Just need to restart the designer for it to pickup the change.
