auto resize compartments in shape scripts

[Ralf]

Is it possible to generate a shape script with a name compartment which is able to expand to a second line if the name gets too long?

The goal is to create a shape like the class shape with a line between the name and the rest of the element.

I only managed to place a line at - let's say - 20% of the shape which will be ok if the name only covers one line. But if it expands to the second line, I can't move the line to - let's say - 40%.

I even tried to use the border layout and hoped that the "N" compartment will be automatically resized. No success.
