| 132 | |
| 133 | The new data passed are in the "int nsel" and "int * selection" |
| 134 | |
| 135 | The idea is to make a multiple selection from list of strings. |
| 136 | The returned value is the total number selected. initialily there |
| 137 | are nsel selected, with indices stored in |
| 138 | selection[0],...,selection[nsel-1] which appear highlighted to |
| 139 | begin with. On exit with value i |
| 140 | selection[0..i-1] contains the indices of the selected items. |
| 141 | (Some prior selectecions might be deselected.) |
| 142 | Thus selection must be as big as choices, in case all items are |
| 143 | selected. |
