[Newbies] How to rescale child Morph when father does ?

[John-Reed Maffeo]

Nicola,

This command will rescale the polygonMorph. I am not sure how it is used in
your example.

1. Run your sample code and create the rectangle.
2. Use the Halo to resize the parent and make sure to maintain the aspect
ratio
3. Launch Explore from the Halo.
4. Find the polygon submorph and select it.
5. In the code space at the bottom of the Explorer do "self bounds: self
owner bounds"

Probably not much help, but perhaps a hint to something that will.
