I tried the following, but i do not know what to do in the acceptDropBlock.
It seems the receiver in the block is only an item in a list, but how do i
get the receiving list/collection?
What i want to achieve is that a user can drag the '1' from list1 to list2
and the resulting collections will then be collection1: (2 3 4 5)
collection2: ($a $b $c $d $e 1) and the lists will be updated accordingly.
| collection1 collection2 list1 list2 |
collection1 := #(1 2 3 4 5).
collection2 := #($a $b $c $d $e).
list1 := ListModel new.
list1 items: collection1.
list1 dragEnabled: true.
list1 dropEnabled: true.
list1 acceptDropBlock: [ :transfer :event :source :receiver :index |
self
halt ].
list1 openWithSpec.
list2 := ListModel new.
list2 items: collection2.
list2 dragEnabled: true.
list2 dropEnabled: true.
list2 acceptDropBlock: [ :transfer :event :source :receiver :index |
self
halt ].
list2 openWithSpec.
