Hi Peter,
Thanks for your prompt answer.
Yes, I meant width :)
How can I retrieve the label (RTLabelled) from an element object (RTElement)?
I don’t have a reference to the label (as in the example) but only to the element.

What do you mean by "the size of the label"? It's width?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|v el lbl|
v := RTView new.
el := RTEllipse new size: 5; elementOn: 'number'.
v add: el.
(lbl := RTLabelled new) fontSize: 30.
el @ lbl.
el @ (RTPopup new text: [:e | lbl lbl width asString]).
v

Or you can be exlicit and add RTLabel as a new shape, but then you would have to manually
setup the interaction.

Hi all,
In the example below. How can I print the size of the label instead of the circle’s size?
v := RTView new.
el := RTEllipse new size: 5; elementOn:'number'.
v add: el.
el @ (RTLabelled new fontSize:30).
el @ (RTPopup new textElement:[:e| e width asString]).
