Qt (pronounced "cute" [7] [8] or as an initialism) is a cross-platform application development framework for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native ...
This is a list of notable library packages implementing a graphical user interface (GUI) platform-independent GUI library (PIGUI). These can be used to develop software that can be ported to multiple computing platforms with no change to its source code.
CLX (Component Library for Cross-platform) was used with Borland's (now Embarcadero's) Delphi, C++ Builder, and Kylix, for producing cross-platform applications between Windows and Linux. It was based on Qt , wrapped in such a way that its programming interface was similar to that of the VCL toolkit.
Qt is popular with application developers using C++ but is supported by bindings for other programming languages too, such as Python. Qt also includes packages such as data structures and a networking library. The popular free and cross-platform KDE Plasma desktop environment and software compilation uses the Qt library.
Website. www .webtoolkit .eu /wt. Wt (pronounced "witty") is an open-source widget -centric web framework for the C++ programming language. It has an API resembling that of Qt framework (although it was developed with Boost, and is incompatible when mixed with Qt), also using a widget-tree and an event-driven signal/slot system. [ 2]
Signals and slots is a language construct introduced in Qt [1] for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code. The concept is that GUI widgets, and other objects, can send signals containing event information which can be received by other objects using special member ...
The Meta object system consists of 3 things: QObject class, Q_OBJECT macro and a tool called moc (Meta-Object Compiler).QObject is the base class for all Qt classes, Q_OBJECT macro is used to enable meta-object features in classes and finally moc is a preprocessor that changes Q_OBJECT macro instances to C++ source code to enable meta object system mechanism in the class in which it is used.
Overview. The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
