Qt is used for developing graphical user interfaces (GUIs) and multi-platform applications that run on all major desktop platforms and mobile or embedded platforms. Most GUI programs created with Qt have a native-looking interface, in which case Qt is classified as a widget toolkit.

Qt (pronounced as "cute", not "cu-tee") is a cross-platform framework that is usually used as a graphical toolkit, although it is also very helpful in creating CLI applications. It runs on the three major desktop OSes, as well as on mobile OSes, such as Symbian, Nokia Belle, Meego Harmattan, MeeGo or BB10, and on embedded devices.

What is Qt? Qt is a cross-platform application development framework for desktop, embedded and mobile. Supported Platforms include Linux, OS X, Windows, VxWorks, QNX, Android, iOS, BlackBerry, Sailfish OS and others. Qt is not a programming language on its own. It is a framework written in C++.

Qt Framework contains cross-platform software libraries and APIs for embedded systems & software development, including Python/C++, Windows, Linux.

2023年11月15日 · Let’s start with the basics, what exactly is Qt? In its simplest terms, Qt is an open-source framework for creating cross-platform applications with a graphical user interface. Qt framework was initially developed by Trolltech, a Norwegian software company, in the mid-1990s. In 2008, Nokia acquired Trolltech and continued to support and develop Qt.

2023年12月23日 · Qt is a cross-platform C++ framework that facilitates the development of applications with graphical user interfaces (GUIs) and provides a wide range of tools and libraries for software development. Originally developed by Trolltech (now part of The Qt Company), Qt has become one of the most popular frameworks in the software development industry.

Qt offers two solutions for UI design: Qt Widgets and Qt Quick. Qt Widgets tightly integrates with desktop look-and-feel. Qt Quick UIs are dynamic with fluid animations and are optimal for touch interfaces.

2023年5月2日 · Qt is a C++ framework that supports the WOCA (Write Once, Compile Anywhere) principle, which means Qt is a cross-platform framework. It’s mainly used to develop applications and graphical user interfaces (GUIs) that can run across different operating systems.

This tutorial will explain in detail how to take your first steps in programming with Qt using the Qt Creator integrated development environment (IDE). If you want to learn how to make powerful GUIs with all the latest fancy technologies, this is not the tutorial for you.
