What is qt under Linux

Qt is a cross-platform C graphical user interface application development framework.

It can develop both GUI programs and non-GUI programs, such as console tools and servers. Qt is an object-oriented framework. Using special code generation extensions (called Meta Object Compiler (moc)) and some macros, Qt is easy to extend and allows true component programming.

Excellent cross-platform features:

Qt supports the following operating systems: Microsoft Windows 95/98, Microsoft Windows NT, Linux, Solaris, SunOS, HP-UX, Digital UNIX (OSF/1, Tru64), Irix, FreeBSD, BSD/OS, SCO, AIX, OS390, QNX, etc.

Object-oriented

Qt's good encapsulation mechanism makes Qt highly modular and reusable, which is very convenient for user development. Qt provides a safe type called signals/slots to replace callback, which makes the collaboration between various components very simple.

Rich API

Qt includes more than 250 C classes, and also provides template-based collections, serialization, file, I/O device, directory management , date/time class. It even includes regular expression processing capabilities.

Supports 2D/3D graphics rendering, supports OpenGL

A large number of development documents
