/**
@class wxRearrangeList
A listbox-like control allowing the user to rearrange the items and to
enable or disable them.
This class allows to change the order of the items shown in it as well as
to check or uncheck them individually. The data structure used to allow
this is the order array which contains the items indices indexed by their
position with an added twist that the unchecked items are represented by
the bitwise complement of the corresponding index (for any architecture
using two's complement for negative numbers representation (i.e. just about
any at all) this means that a checked item N is represented by -N-1 in
unchecked state). In practice this means that you must apply the C bitwise
complement operator when constructing the order array, e.g.
@code
wxArrayInt order;
order.push_back(0); // checked item #0
order.push_back(~1); // unchecked item #1
@endcode
So, for example, the array order [1 -3 0] used in conjunction with the
items array ["first", "second", "third"] means that the items order is
"second", "third", "first" and the "third" item is unchecked while the
other two are checked.
This convention is used both for the order argument of the control ctor or
Create() and for the array returned from GetCurrentOrder().
Usually this control will be used together with other controls allowing to
move the items around in it interactively. The simplest possible solution
is to use wxRearrangeCtrl which combines it with two standard buttons to
move the current item up or down.
