Listbox is not OS dependant- fully owner-drawn (use event OnDrawItem)
It 's for CudaText editor to mimic SublimeText listbox (with other colors)
Has no Items prop. Has ItemIndex, ItemCount- just set ItemCount and do painting on event- you can paint any string/icon
If CanGetFocus set, it's getting focus on click
(else it don't focus on click like Sublime and you need to handle OnKeyDown in form)
