Extended-selection list: the user can select multiple items using the SHIFT key and the mouse or special key combinations.

Create horizontal scrollbar if contents are too wide (Windows only).

Always show a vertical scrollbar.

wxLB_NEEDED_SB
Only create a vertical scrollbar if needed.

The listbox contents are sorted in alphabetical order.
