Haha, ok, that's not exactly the answer I was hoping for, but well, I
can't say it was a complete surprise ;-)

I'll try grokking drag&drop implementation in Pharo next week and
doing something with it. In my app I'm going to have one very long
list as a source and a few other lists as destinations. To make it
worthwhile I need to have support for dragging all items a current

The problem is, dragging stars after the mouse click on the list items
changes the selection. That means, selecting all items and after
that click on one item to start dragging, this item will be unselected.

You can select all but one item and then click AND drag the last item.

��
selection and additionally a way to make selection non-continuous,
essentially what most list widgets do with Ctrl+click.

This should work (justed test this with�� a ListModel with multiselection enabled)

��

Any help appreciated!


Best regards,
Piotr Klibert
