// wxRearrangeList: a (check) list box allowing to move items around
// ----------------------------------------------------------------------------

// This class works 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).
//
// So, for example, the array order [1 -3 0] used in conjunction with the items
// array ["first", "second", "third"] means that the items are displayed in the
// order "second", "third", "first" and the "third" item is unchecked while the
// other two are checked.
