Qt is an open source application framework developed the Qt Project, involving individuals and companies - notably Nokia. Many Qt applications are written in C++, although bindings to other languages are available. KDE desktop environment is based on Qt.

Qt is not standard on Puppy. However, much work has been done to implement the framework. Generally speaking to run a Qt application on Puppy requires the installation of a software package. Similarly, to compile or develop a Qt app, a package is required (usually with 'dev' in its name). See Software Packages below, or Qt installation.

Polarpup comes with Qt4 as standard and some Qt apps such as Clementine and its devx has the development files. This makes using Qt applications very easy.

QtPuppy is version of Puppy that uses Qt4 as the default framework, currently under development by scsijon. The first step is to get Mageia 2 based Puppy up and running, then later a version using Mageia 3. These will then be branched into QtPuppy. To help test please see, this forum page.

Qt5 will be a 'different' beastie to Qt3/Qt4. It will be using cloud applications as the base rather than Qt4's workstation/server focus.
