       QStrList - Doubly-linked list of char*

       #include <qstrlist.h>

       Inherits QPtrList<char>.

       Inherited by QStrIList.

   Public Members
       QStrList ( bool deepCopies = TRUE )
       QStrList ( const QStrList & list )
       ~QStrList ()
       QStrList & operator= ( const QStrList & list )

       The QStrList class provides a doubly-linked list of char*.

       If you want a string list of QStrings use QStringList.

       This class is a QPtrList<char> instance (a list of char*).

       QStrList can make deep or shallow copies of the strings that are inserted.

       A deep copy means that memory is allocated for the string and then the string data is
       copied into that memory. A shallow copy is just a copy of the pointer value and not of the
       string data itself.

       The disadvantage of shallow copies is that because a pointer can be deleted only once, the
       program must put all strings in a central place and know when it is safe to delete them
       (i.e. when the strings are no longer referenced by other parts of the program). This can
       make the program more complex. The advantage of shallow copies is that they consume far
       less memory than deep copies. It is also much faster to copy a pointer (typically 4 or 8
       bytes) than to copy string data.

       A QStrList that operates on deep copies will, by default, turn on auto-deletion (see
       setAutoDelete()). Thus, by default QStrList will deallocate any string copies it

       The virtual compareItems() function is reimplemented and does a case-sensitive string
       comparison. The inSort() function will insert strings in sorted order. In general it is
       fastest to insert the strings as they come and sort() at the end; inSort() is useful when
       you just have to add a few extra strings to an already sorted list.

       The QStrListIterator class is an iterator for QStrList.

       See also Collection Classes, Text Related Classes, and Non-GUI Classes.

QStrList::QStrList ( bool deepCopies = TRUE )
       Constructs an empty list of strings. Will make deep copies of all inserted strings if
       deepCopies is TRUE, or use shallow copies if deepCopies is FALSE.

QStrList::QStrList ( const QStrList & list )
       Constructs a copy of list.

       If list has deep copies, this list will also get deep copies. Only the pointers are copied
       (shallow copy) if the other list does not use deep copies.

QStrList::~QStrList ()
       Destroys the list. All strings are removed.

QStrList &; QStrList::operator= ( const QStrList & list )
       Assigns list to this list and returns a reference to this list.

       If list has deep copies, this list will also get deep copies.  Only the pointers are
       copied (shallow copy) if the other list does not use deep copies.
