ABSTRACT
Qt is an open-source, cross-platform application framework that is perhaps best known for its widget toolkit. The features of Qt are divided into about a dozen modules. We highlight some of the more important and interesting ones:
Core Basic utilities, collections, threads, I/O, …
Gui Widgets, models, etc., for graphical user interfaces
OpenGL Convenience layer (e.g., 2-D drawing API) over OpenGL
Webkit Embeddable HTML renderer (shared with Safari, Chrome)
