Sorry, i don't want to stress on this, but with the code i sent yesterday, i haven't be able to do what i need, is a my mistake ? In the way you told me i wasn't able to keep previously selected elements, when changing the mode. Or changing it to disabled works but i got another effect, is this the right way you ?
For your use case, disabling the component sounds like the right thing to do.
Then, suppose that we have a disabled List/Table/Tree: in case they containing many elements (so a scrollbar is visible), with the container disabled, will it be possible to use the scrollbar to scroll all their elements ?
Yes. The scroll bar is not part of the component (FYI, you have to put the list view (or table view, or tree view) in a ScrollPane if you need scrolling behavior).
