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.
