<b>This class is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
<p> The QAsyncIO class encapsulates I/O asynchronicity.
<p> The Qt classes for asynchronous input/output provide a simple
mechanism to allow large files or slow data sources to be processed
without using large amounts of memory or blocking the user interface.
<p> This facility is used in Qt to drive animated images.  See <a href="qimageconsumer.html">QImageConsumer</a>.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="~QAsyncIO"></a>QAsyncIO::~QAsyncIO ()<tt> [virtual]</tt>
</h3>
Destroys the async IO object.

<h3 class=fn>void <a name="connect"></a>QAsyncIO::connect ( <a href="qobject.html">QObject</a>&nbsp;*&nbsp;obj, const&nbsp;char&nbsp;*&nbsp;member )
</h3>
Ensures that only one object, <em>obj</em> and function, <em>member</em>, can
respond to changes in readiness.

<h3 class=fn>void <a name="ready"></a>QAsyncIO::ready ()<tt> [protected]</tt>
</h3>
Derived classes should call this when they change from being
unready to ready.
