Thanks Nicolai,

unfortunately, even using images of the same height I obtain a list
with thin rows. Maybe I'm typing something wrong.

I'll try to figure out how to handle this.
Please let me know, if you have any further suggestion.

Thanks,
Matteo

For Images with the same height/width, you can use #buildWithSpecLayout: in the displayBlock and

use a SpecTableLayout with the width/height of the image model image.

But this doesn't really work, somehow the list widget can not handle the selection and scrolling (but the images are shown in full size) :

imageModels := (1 to:10) collect:[:i | ImageModel new image: PolymorphSystemSettings pharoLogoForm].
listModel := ListModel new items: imageModels.
listModel displayBlock:[:item | | layout |
layout := SpecTableLayout row add:#yourself; height: item image height; width: item image width.
item buildWithSpecLayout: layout].
listModel openWithSpec
