130 | * | |
131 | ||
132 | The new data passed are in the "int nsel" and "int * selection" | |
133 | ||
134 | The idea is to make a multiple selection from list of strings. | |
135 | The returned value is the total number selected. initialily there | |
136 | are nsel selected, with indices stored in | |
137 | selection[0],...,selection[nsel-1] which appear highlighted to | |
138 | begin with. On exit with value i | |
139 | selection[0..i-1] contains the indices of the selected items. | |
140 | (Some prior selectecions might be deselected.) | |
141 | Thus selection must be as big as choices, in case all items are | |
142 | selected. | |
