Hi Hernan,

Yes, label size can be easily set up. Check this:

-=-=-=-=-=-=-=-=-=-=-=-=
v := RTView new.

shape := RTLabel new height: #yourself.
labels := shape elementsOn: (5 to: 30 by: 5).
v addAll: labels.

RTFlowLayout on: labels.

v
-=-=-=-=-=-=-=-=-=-=-=-=

I suspect that in your case, you need to keep the size of the label when you zoom in. Is that correct?
If this is the case, then you may need to fix the elements:
-=-=-=
v := RTView new.

shape := RTLabel new height: #yourself.
labels := shape elementsOn: (5 to: 30 by: 5).
labels do: #setAsFixed.
v addAll: labels.

RTFlowLayout on: labels.

v
-=-=-=-=

But you cannot scroll them. Let me know what you exactly need.
