This course will take you from zero to a level where you can write any Qt C++ Gui application you may want. It is aimed at complete beginners but people with varying levels of experience wishing to learn Qt C++ Gui will equally find it useful. Qt is second to none in the field of building cross platform GUI application based on C++. Threads Events QObjects - Qt Wiki Events and the event loop. We enter Qt's main event loop by running QCoreApplication::exec(); this call blocks until QCoreApplication::exit() or QCoreApplication::quit() are called, terminating the loop. The "wait_for_more_events()" function blocks (that is, it's not a busy wait) until some event is generated. Qt bug?
