What is Qt?

• Qt is a cross-platform application framework

that is widely used for developing application software with graphical user interface (GUI) (in which case Qt is referred to as a widget toolkit when used as such)

• Qt uses standard C++

but makes extensive use of a special code generator (called the Meta Object Compiler, or moc)

• Qt can also be used in several other programming languages

via language bindings.

• It runs on all major platforms

• Non-GUI features include

• • SQL database access,

• • XML parsing,

• • thread management,

• • network support,

• • and a unified cross-platform API for file handling.

• GNU Lesser General Public License, Qt is free and open source
