NAME
       QStrList - Doubly-linked list of char*

SYNOPSIS
       #include <qstrlist.h>

       Inherits QPtrList<char>.

       Inherited by QStrIList.

       QStrList & operator= ( const QStrList & list )

DESCRIPTION
       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 allocates.

       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.

MEMBER FUNCTION DOCUMENTATION
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.
