QtDispatch is an additional Qt Module building on QtCore and providing a custom Qt adapted interface to use libdispatch.
This interface is fully compatible with the generic C++ interface provided by libxdispatch.
As integration into Qt, it is possible to dispatch QRunnables onto groups and queues the same way as when executing them on a QThreadPool. Going along with that we added QBlockRunnable, a simple QRunnable created by passing an individual block.
For integrating the main queue into your Qt Application there is a QDispatchApplication which can be used as a drop-in replacement to QApplication. It will call xdispatch::exec() internally and ensure that all work dispatched to the main queue is executed on the main/gui thread. That way it is very easy to send gui updates to the main thread. All other functionality is equal to that of QApplication.
You can use QtDispach (in case you have Qt > 4.6 available on your system) by including the QtDispatch header or one of the individual modules - this will automatically include all other needed headers as well. Below you find a list of the available classes.
The corresponding headers have the same name and can be included all by once using
#include <QtDispatch/QtDispatch>
Please link your program with qtdispatch and xdispatch.
