Threading and Concurrent Programming Examples

Qt 4 makes it easier than ever to write multithreaded applications. More classes have been made usable from non-GUI threads, and the signals and slots mechanism can now be used to communicate between threads.

Additionally, it is now possible to move objects between threads.

The QtConcurrent namespace includes a collection of classes and functions for straightforward concurrent programming.

These examples show how to apply the basic techniques of concurrent programming to simple problems.
