I would like to present a user with a set of items which is variable in
length (and can be pretty large, as in 20-30) to be selected or
deselected. The set starts out in a state where certain items are
already selected (the current set) and can be changed by the user. The
fact that the table view currently starts out with, say, items 1-4,8,26
selected.
This would be best presented as a 'variable list of checkboxes'. You
start out with a set of choices, and you modify that. In other words,
you are presented with a set of options, either turned off or on and it
starts out with the currently active options as selected. So, what
happens then is that a user selects an extra option or deselects an
active option, and currently - due to default NSTableView behaviour -
as a side effect, all other already selected options at the start of
the table view are deselected. This is confusing, because most of those
options were never seen by the user (outside the scroll area). So, the
user selects a new item and does not notice that all others that are
already selected at the start are deselected.
Maybe I should add: this is presented to *very* non-technical users and
I must assume *very* little computer literacy. In fact, I did present a
beta group with the standard table view solutions and it turned out it
was confusing.
Were it a fixed set op options, it would be implemented with
checkboxes. But the set has a variable length, so I need a table view
solution that behaves like checkboxes (single itemn select and
deselect), or in other words, the way a table view would behave when
every event was a Cmd-click.
