Listboxes in Igor Pro

A listbox is backed by waves: one for the text, one for the selection.

Function AddList()
    Make/O/T/N=0 root:Settings:listText
    Make/O/N=0 root:Settings:listSel
    WAVE/T listText = root:Settings:listText
    WAVE listSel = root:Settings:listSel

    String names = WaveList("*", ";", "")
    Variable n = ItemsInList(names)
    Redimension/N=(n) listText, listSel
    listText = StringFromList(p, names)

    ListBox waveList, pos={16, 210}, size={280, 90}, mode=4
    ListBox waveList, listWave=listText, selWave=listSel
End

How it works

1. listWave= holds the rows; selWave= holds the per-row state.
2. mode= decides single, multiple or checkbox selection.
3. Changing the wave changes the list; there is nothing else to refresh.
