The QStrList class provides a doubly-linked list of char*.
<p>
<p> If you want a string list of QStrings use <a href="qstringlist.html">QStringList</a>.
<p> This class is a <a href="qptrlist.html">QPtrList</a><char> instance (a list of char*).
<p> QStrList can make deep or shallow copies of the strings that are inserted.
<p> A <a href="shclass.html#deep-copy">deep copy</a> means that memory is allocated for the string and then
the string data is copied into this memory. A <a href="shclass.html#shallow-copy">shallow copy</a> is just
a copy of the pointer value and not of the string data itself.
<p> 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 shallow copies 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.
<p> A QStrList that operates on deep copies will, by default, turn on
auto-deletion (see <a href="qptrcollection.html#setAutoDelete">setAutoDelete</a>()). Thus, by default QStrList will
deallocate any string copies it allocates.
<p> The virtual <a href="qptrlist.html#compareItems">compareItems</a>() function is reimplemented and does a
case-sensitive string comparison. The <a href="qptrlist.html#inSort">inSort</a>() function will insert
strings in a sorted order. In general it is fastest to insert the
strings as they come and <a href="qptrlist.html#sort">sort</a>() at the end; inSort() is useful
when you just have to add a few extra strings to an already sorted
list.
<p> The <a href="qstrlistiterator.html">QStrListIterator</a> class is an iterator for QStrList.
<p>See also <a href="collection.html">Collection Classes</a>, <a href="text.html">Text Related Classes</a> and <a href="tools.html">Non-GUI Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QStrList"></a>QStrList::QStrList ( bool deepCopies = TRUE )
</h3>
Constructs an empty list of strings. Will make deep copies of all inserted
strings if <em>deepCopies</em> is TRUE, or use shallow copies if <em>deepCopies</em>
is FALSE.
<h3 class=fn><a name="QStrList-2"></a>QStrList::QStrList ( const <a href="qstrlist.html">QStrList</a> & list )
</h3>
Constructs a copy of <em>list</em>.
<p> If <em>list</em> 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.
<h3 class=fn><a name="~QStrList"></a>QStrList::~QStrList ()
</h3>
Destroys the list. All strings are removed.
<h3 class=fn><a href="qstrlist.html">QStrList</a> & <a name="operator-eq"></a>QStrList::operator= ( const <a href="qstrlist.html">QStrList</a> & list )
</h3>
Assigns <em>list</em> to this list and returns a reference to this list.
<p> If <em>list</em> 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.
