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

    Hi,
            I've created a list of pictures, i.e. a widget based on
    ListModel where
    each item is a ImageModel.
When the widget is displayed I get list window with very
    thin rows.
Is there a way to control the ListModel rows height?
Not if the images have different heights (you can, but it looks
terrible, because the underlaying list morph does not work for list
items with different heights).
Thanks,
    Matteo
