VRuby-question: yellow rectangle; lines around elements

Hi all,

I certainly miss the obvious.

The two points below must be simple - if one
knows the API. Thank you!

On a Form, I would like to have:

  • simple lines around a few VRButtons, VREdit, etc.
    to show that part of the input belongs together;
  • a big yellow bar (rectangle) with text as a heading;

my Form should look like:

--------------------------------------|
---------------------------------- |
> yellow rectangle with text | |
> VRstatics | |
> VRStatics | |
--------------------------------| |

other stuff

The outer frame should be my Form;
The inner frame is the lines around the group
of elements I want to group together.

Thank you,
-Armin
