88
89       delete(This, N) -> ok
90
91              Types:
92
93                 This = wxChoice()
94                 N = integer()
95
96              Deletes an item from the control.
97
98              The client data associated with the item will be also deleted if
99              it  is owned by the control. Note that it is an error (signalled
100              by an assert failure in debug builds) to remove an item with the
101              index  negative  or greater or equal than the number of items in
102              the control.
103
104              If there is a currently  selected  item  below  the  item  being
105              deleted,  i.e.  if  wxControlWithItems:getSelection/1  returns a
106              valid index greater than or equal to n, the selection is invali‐
107              dated when this function is called. However if the selected item
108              appears before the item being deleted,  the  selection  is  pre‐
109              served unchanged.
