Qt is a cross-platform application and UI framework.
Qt enables you to build software applications running on two or more desktop operating systems and embedded devices without rewriting the source code. By utilizing your investment in single-platform software development for many other platforms with Qt, the time-to-market can be shortened and the productivity can be improved.
