+ List box elements are numbered from zero and while the maximal number of
+ elements is unlimited, it is usually better to use a virtual control, not
+ requiring to add all the items to it at once, such as wxDataViewCtrl or
+ wxListCtrl with @c wxLC_VIRTUAL style, once more than a few hundreds items
+ need to be displayed because this control is not optimized, neither from
+ performance nor from user interface point of view, for large number of
+ items.
