Multithreaded appliances are becoming a standard each developer must know at his best. Qt, one of the most popular Open Source frameworks, powering projects such as MeeGo and KDE, is also among one of the most popular libraries providing multi-thread facilities.

Lots of developers are already taking advantage of Qt and his multi-threading facilities, but most of the times, they are not familiar with the least known features, which could greatly improve their work. Are you creating a separate thread for processing a single method? Are you processing a list of elements in a single thread, or just in a separate one? Uploading textures to OpenGL from the main thread? Or worse, disregarding threads at all? This talk is for you.

Besides showing the usage of the most common features, such as QThread, QMutex or QSemaphore, this talk will strongly focus on uncommon features such as QtConcurrent or the new threaded OpenGL support, which are what makes Qt really taking a stand, and can ease your life as a developer while improving performance.

A variety of demos for each topic will be shown, to see how each component can fit into a real-world appliance.
