Hi Stef,
I think that an automatic scaled behaviour is very useful for
ImageModel,
especially if you need to generate list of images, that automatically adapts
to their container (i.e. Thumbnails).
Playing with AlpahImageMorph I found that the desired behaviour can be
obtained setting the "layout" state to the "#scaledAspect" symbol.
So I've added the "ImageModel>>switchScaledLayout" method, that will
simply
call its MorphicAdapter, through the command "self changed:
#switchScaledLayout with: {}".
Then I've created the "MorphicImageAdapter>>switchScaledLayout" method,
that switchs among the "#center" and "#scaledAspect" morph layouts (note:
"#center" is the default for the Spec's "MorpdicImageAdapter").
Below the code the code I used:
MorphicImageAdapter>>switchScaledLayout
"Switch between scaled and fixed representation"
self
widgetDo: [ :w |
| oldLayout |
oldLayout := w layout.
oldLayout = #scaledAspect
ifTrue: [ w layout: #center ]
ifFalse: [ w layout: #scaledAspect ] ].
Please let me know if you have any advice,
Thanks,
Matteo
