<hr><h2><a name="details"></a>Detailed Description</h2>
The QQueue class is a template class that provides a queue.
<p>
QQueue is implemented as a template class. Define a template
instance QQueue<X> to create a queue that operates on pointers to
X, or X*.
<p>A queue is a First In, First Out (FIFO) structure. Items are added
to the back of the queue with <a href="#67b0b6">enqueue</a>() and retrieved from the front
with <a href="#b8b005">dequeue</a>().
<p>See also <a href="collection.html">Collection Classes</a>

<h3 class="fn"><a name="b8b70d"></a>QQueue::QQueue()</h3>
<p>Creates an empty queue.
<h3 class="fn"><a name="1be70f"></a>QQueue::QQueue(constQQueue<type>&queue)</h3>
<p>Creates a queue from another.
<p>Only the pointers are copied (shallow copy).
<h3 class="fn"><a name="17701e"></a>QQueue::~QQueue()</h3>
<p>Destroys the list. Items in the list are destroyed if <a href="#1e17ee">autoDelete</a>() is TRUE.
<h3 class="fn"><a name="110bb3"></a>QQueue::operatortype*()const</h3>
<p>Returns a reference to the front item in the queue. The queue is
not changed.
<h3 class="fn">bool<a name="1e17ee"></a>QQueue::autoDelete()const</h3>
<p>The same as <a href="qcollection.html#05b849">QCollection::autoDelete</a>().
<p>See also <a href="#342a2b">setAutoDelete</a>().
<h3 class="fn">void<a name="8f56c9"></a>QQueue::clear() <code>[virtual]</code></h3>
<p>Removes all items from the queue, deleting them if
if <a href="#1e17ee">autoDelete</a>() is TRUE.
<p>See also <a href="#876afe">remove</a>().
<p>Reimplemented from <a href="qcollection.html#10eb2d">QCollection.</a>
<h3 class="fn">uint<a name="5436fb"></a>QQueue::count()const <code>[virtual]</code></h3>
<p>Returns the number of items in the queue.
<p>See also <a href="#6f4506">isEmpty</a>().
<p>Reimplemented from <a href="qcollection.html#649c42">QCollection.</a>
<h3 class="fn">type*<a name="ad2472"></a>QQueue::current()const</h3>
<p>Returns a reference to the front item in the queue. The queue is
not changed.
<h3 class="fn">type*<a name="b8b005"></a>QQueue::dequeue()</h3>
<p>Takes the front item from the queue. First in, first out.
<h3 class="fn">void<a name="67b0b6"></a>QQueue::enqueue(consttype*d)</h3>
<p>Adds an item to the back of the queue. First in, first out.
<h3 class="fn">type*<a name="bcccec"></a>QQueue::head()const</h3>
<p>Returns a reference to the front item in the queue. The queue is
not changed.
<h3 class="fn">bool<a name="6f4506"></a>QQueue::isEmpty()const</h3>
<p>Returns TRUE if there are no items to be <a href="#b8b005">dequeued</a>
<h3 class="fn">QQueue<type>&<a name="2d5bc8"></a>QQueue::operator=(constQQueue<type>&queue)</h3>
<p>Assigns <em>queue</em> to this queue and returns a reference to this queue.
<p>This queue is first cleared, then each item in <em>queue</em> is
enqueued to this queue. Only the pointers are copied (shallow copy).
<h3 class="fn">bool<a name="876afe"></a>QQueue::remove()</h3>
<p>Removes the front item from the queue. First in, first out.
The item is deleted if <a href="#1e17ee">autoDelete</a>() is TRUE.
Returns TRUE if there was an item to remove.
<h3 class="fn">void<a name="342a2b"></a>QQueue::setAutoDelete(boolenable)</h3>
