== Programming Language Support & Language Bindings ==
#REDIRECT [[Language Bindings]]
 
The Qt API is implemented in C++, and provides additional features for easier cross-platform development. QML – introduced with Qt Quick is a CSS and JavaScript-like declarative, language designed to describe the user interface of a program: both what it looks like, and how it behaves. Bindings to Qt exist for several other languages, including Ada, Pascal, Perl, PHP, Ruby, Python and Java™.
 
== C++ Development with Qt ==
 
Qt provides an intuitive C++ class library with a rich set of application build blocks for C++ development. Qt goes beyond C++ in the areas of inter-object communication and flexibility for advanced GUI development. Qt adds the following features to C+'':
 
* Powerful mechanism for inter-object communication called "signals and slots":https://doc.qt.io/qt-5/signalsandslots.html
* Queryable and designable "object properties ":https://doc.qt.io/qt-5/properties.html#qt-s-property-system
* Powerful "events and events filters ":https://doc.qt.io/qt-5/eventsandfilters.html
* Contextual "string translation for internationalization ":https://doc.qt.io/qt-5/i18n.html
* Sophisticated interval driven "timers":https://doc.qt.io/qt-5/timers.html that make it possible to elegantly integrate many tasks in an event-driven GUI
* Hierarchical and queryable "object trees":https://doc.qt.io/qt-5/objecttrees.html that organize object ownership in a natural way
* "Guarded pointers":https://doc.qt.io/qt-5/qpointer.html that are automatically set to 0 when the referenced object is destroyed, unlike normal C++ pointers which become dangling pointers when their objects are destroyed
* A "dynamic cast ":https://doc.qt.io/qt-5/metaobjects.html works across library boundaries.
 
== QML Development with Qt Quick ==
 
QML is a declarative, JavaScript-based language designed to describe the user interface of a program: both what it looks like, and how it behaves. In QML, a user interface is specified as a tree of objects with properties.
 
* JavaScript, HTML and CSS skills can be used to code complete apps
* Optimized for touch-based, animated mobile UIs
* Includes a set of graphical and behavioral building blocks: "QML Elements ":http://doc.qt.nokia.com/4.7/qdeclarativeelements.html
* No C++ knowledge required for UI creation, but can be extended with C++

==== "official PerlQt and PerlKDE":https://projects.kde.org/projects/kde/kdebindings/perl ====
 
This is what the Linux distros ship. Expect updates for Qt5 in 2013. Subscribe to the "kde-bindings list":http://lists.kde.org/?l=kde-bindings for news.
 
This repository used to be at "Google code":http://code.google.com/p/perlqt4/, then moved to KDE in 2012. Some outdated code snapshots are on "CPAN":http://search.cpan.org/~cburel/; prefer the KDE repository.

=== "Qt for Haskell":http://qthaskell.berlios.de/ (qtHaskell) ===
 
The qtHaskell project provides a set of Haskell bindings for Qt. Haskell programmers can access the "Signals and Slots" interface logic, design interfaces using Qt Designer and write scripted applications using the Qt ECMA/Javascript engine.
