< 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 This class is obsolete.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 TQAsyncIO class encapsulates I/O asynchronicity.
< p > The TQt 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 TQt to drive animated images. See < a href = "tqimageconsumer.html" > TQImageConsumer< / a > .
< hr > < h2 > Member Function Documentation< / h2 >
< h3 class = fn > < a name = "~TQAsyncIO" > < / a > TQAsyncIO::~TQAsyncIO ()< tt > [virtual]< / tt >
< / h3 >
Destroys the async IO object.
< h3 class = fn > void < a name = "connect" > < / a > TQAsyncIO::connect ( < a href = "tqobject.html" > TQObject< / 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 > TQAsyncIO::ready ()< tt > [protected]< / tt >
< / h3 >
Derived classes should call this when they change from being
unready to ready.
