One model, different rows in different views

[Diego Zuccato <diego otello alma unibo it>]

Hello all.

It the subj possible ?
Like having a model with, say, a list of objects.
At start all objects are in a view and the other is empty.
When a cell changes, that object is "moved" to the other view.

An example could be a "chooser":

VIEW1      VIEW2
item1
item2  ->
item3  <-
item4

(model contains {"Item1", 1}, {"Item2", 1}, {"Item3", 1}, {"Item4", 1})

After selecting item3 and clicking "->" :

VIEW1      VIEW2
item1      Item3
item2  ->
item4  <-

(model now contains {"Item1", 1}, {"Item2", 1}, {"Item3", 2}, {"Item4",
1})

Tks,
 Diego.
