Spec: Setting rows height of a pictures list

Pharo Smalltalk Users mailing list
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?


Thanks,
Matteo

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 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 Nicolai,
        I think it would be great to have a specific ListModel for pictures,
like the IconListModel.

        Do you know if there's already someone working on a "picture" ListModel?
        Could I try to implement it, and its morphic adapter?

Thanks,
Matteo

Sure!
Now pay attention that it is probably better to use FastTable on the morphic level. 


Thanks,

I think the adaptor will called "MorphicImageFastTableAdaptor", and the model "ImageFastTableAdapter".

In the package "Spec-MorphicAdapters", the "MorphicFastTableAdapter" uses an object "FTPluggableIconListMorphAdaptor".

Could the "MorphicImageFastTableAdaptor" use directly a "FTTableMorph" object, instead of creating "pluggable" adapter?

cheers,
Matteo

I would say yes because as you I find this suboptimal.
Now may be it was created like that because of incompatibilities between
uses of PluggableIconListMorph (RIP) and FT.
Nothing is simple when you have legacy and different interaction protocol
