|
|
<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This class is obsolete.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>.

<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> * obj, const char * 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.
