+
+
+The QPair class is a value-based template class that provides a pair of elements.
+<p>
+
+
+<p> QPair is a Qt implementation of an STL-like pair. It can be used
+in your application if the standard pair&lt;&gt; is not available on
+your target platforms.
+<p> QPair&lt;T1, T2&gt; defines a template instance to create a pair of
+values that contains two values of type T1 and T2. Please note
+that QPair does not store pointers to the two elements; it holds a
+copy of every member. This is why these kinds of classes are
+called <em>value based</em>. If you're interested in <em>pointer based</em>
+classes see, for example, <a href="qptrlist.html">QPtrList</a> and <a href="qdict.html">QDict</a>.
+<p> QPair holds one copy of type T1 and one copy of type T2, but does
+not provide iterators to access these elements. Instead, the two
+elements (<tt>first</tt> and <tt>second</tt>) are public member variables of
+the pair. QPair owns the contained elements. For more relaxed
+ownership semantics, see <a href="qptrcollection.html">QPtrCollection</a> and friends which are
+pointer-based containers.
+<p> Some classes cannot be used within a QPair: for example, all
+classes derived from <a href="qobject.html">QObject</a> and thus all classes that implement
+widgets. Only "values" can be used in a QPair. To qualify as a
+value the class must provide:
+<p> <ul>
+<li> A copy constructor
+<li> An assignment operator
+<li> A constructor that takes no arguments
+</ul>
+<p> Note that C++ defaults to field-by-field assignment operators and
+copy constructors if no explicit version is supplied. In many
+cases this is sufficient.
+<p> QPair uses an STL-like syntax to manipulate and address the
+objects it contains. See the <a href="qtl.html">QTL
+ documentation</a> for more information.
+<p> Functions that need to return two values can use a QPair.
+<p>See also <a href="qtl.html">Qt Template Library Classes</a>, <a href="shared.html">Implicitly and Explicitly Shared Classes</a>, and <a href="tools.html">Non-GUI Classes</a>.
+
+<hr><h2>Member Type Documentation</h2>
+<h3 class=fn><a name="first_type"></a>QPair::first_type</h3>
+The type of the first element in the pair.
+<h3 class=fn><a name="second_type"></a>QPair::second_type</h3>
+The type of the second element in the pair.
+<hr><h2>Member Function Documentation</h2>
+<h3 class=fn><a name="QPair"></a>QPair::QPair ()
+</h3>
+
+<p> Constructs an empty pair. The <tt>first</tt> and <tt>second</tt> elements are
+default constructed.
+
+<h3 class=fn><a name="QPair-2"></a>QPair::QPair ( const&nbsp;T1&nbsp;&amp;&nbsp;t1, const&nbsp;T2&nbsp;&amp;&nbsp;t2 )
+</h3>
+
+<p> Constructs a pair and initializes the <tt>first</tt> element with <em>t1</em>
+and the <tt>second</tt> element with <em>t2</em>.
+
+<hr><h2>Related Functions</h2>
+<h3 class=fn><a href="qpair.html">QPair</a> <a name="qMakePair"></a>qMakePair ( T1&nbsp;t1, T2&nbsp;t2 )
+</h3>
+
+<p>
+<p> This is a template convenience function. It is used to create a
+QPair&lt;&gt; object that contains <em>t1</em> and <em>t2</em>.
