/* Multiple choice dialog contributed by Robert Cowell

|
|
|
|
The new data passed are in the "int nsel" and "int * selection"
|
|
|
|
The idea is to make a multiple selection from list of strings.
|
|
The returned value is the total number selected. initialily there
|
|
are nsel selected, with indices stored in
|
|
selection[0],...,selection[nsel-1] which appear highlighted to
|
|
begin with. On exit with value i
|
|
selection[0..i-1] contains the indices of the selected items.
|
|
(Some prior selectecions might be deselected.)
|
|
Thus selection must be as big as choices, in case all items are
|
|
selected.
