.SH DESCRIPTION
Encapsulates I/O asynchronicity.
.PP
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.
.PP
This facility is used in Qt to drive animated images. See QImageConsumer.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QAsyncIO::~QAsyncIO () \fC[virtual]\fR"

.SH "void QAsyncIO::connect ( QObject * obj, const char * member )"
Ensures only one object can respond to changes in readiness.
.SH "void QAsyncIO::ready () \fC[protected]\fR"
Derived classes should call this when they change from being
unready to ready.
