Detailed Description

Encapsulates I/O asynchronicity.

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.

This facility is used in Qt to drive animated images. See QImageConsumer.
