[Squeakland] resizing doesn't stick in holder animation

[Dreyfuss Pierre-André (EDU)]

 Hi,

Try this with an ellipse.
If you change the scale factor, the yellow hallo will be gold,
Squak will take a picture of the object at the original size , then show and resize this picture. Unless you put the scale factor to 1, you can not change length or width of the ellipse and the scale factor will change as you move the gold hallo.(as the scale factor is shown as an integer, it will step on integer values.)

If the scale factor is 1, the hallo is light yellow and you can change length or width of the ellipse again.

If you turn the ellipse with the bleu hallo, it is the same thing,you must turn back and get the light blue hallo (just a moment)to be able to to change length and width again.

in other word there are two states one with light yellow hallo, shape can be mofified qnd object is not resized by "look like", one with gold hallo for which resizing is working.

Regards

I'm still confused by this behavior and apparent solution.  For
starters,
where exactly do you put/use the scale factor tile?  I've attached the
situation I was describing - which doesn't produce the desired behavior.
I
can imagine that a child/user would expect wysiwyg of items in the
Holder
and would expect to see the sketch animate/change size -- I certainly
did.

Aside: once again, I'm learning something interesting about Squeak that
I
didn't know.  In this case, the interplay between a sketch's Scale halo
and
the scalefactor tile in the Geometry category.  I now understand that
the
scalefactor is a global scale whereas the Scale halo allows for x/y
scaling
and doesn't affect the scalefactor - even, for example, when you would
hold
Shift to maintain aspect ratio.  I also realize that once you do change
the
scalefactor, you can no longer do x/y scaling (independently) using the
halo.
