nsDialogs - using ${NSD_CreateListBox}

[johnbm]

I'm interested in using a listbox in nsDialogs. It's unclear to me from the documentation I have seen though how one can populate the listbox and once this is done how one captures the selection made in the listbox.

If I use the code:

${NSD_CreateListBox} 100 40 20% 12u "sample entry"

it will create a blank listbox.

Would anyone be able to clarify this for me?

Thanks, John
