Getting Started with Qt
This guide shows how to get started developing with Qt.
The installation process is straightforward. The Qt Online Installer gives you the choice of installing only the modules and tools you need.
To begin, create a Qt Account. This account gives you access to a web portal to manage your licenses and access to the forums and wikis. Also, make sure you read the Qt Licensing page regarding your chosen license.
Download the installer from the Downloads page. With the Qt Online Installer, you can install both commercial or open source versions of Qt, development tools, and other components. The online installer requires your Qt Account. The installer retrieves the license attached to the account from a server and provides a list of available components corresponding to the license.
To complete the installation, select the components that you want to install and follow the instructions of the installation program.
The following YouTube video gives a complete walk-through of the installation process:
Once Qt is installed, you can use the Maintenance Tool under <install_dir> to add components, update, or remove installed components.
Learn the basics of Qt and Qt Quick development by following the two tutorials below that illustrate how to create simple applications and build and run them on target platforms:
Qt Widgets provides a library of UI elements which allow you to create classic desktop-style user interfaces. Qt Quick is a library providing types and functionalities for building modern, fluid, animated UIs.
For a more thorough walkthrough of the different aspects of developing applications with Qt, see the QML Book. It focuses on Qt Quick, but also provides the information needed to use QML together with C++.
We invite you to explore the rest of Qt. We prepared overviews which help you decide which APIs to use and our examples demonstrate how to use them.

Qt's vibrant and active community site http://qt.io, houses a wiki, a forum, and additional learning guides and presentations.
Evaluation and open source users can get help on the Qt forum. See also the Help on using the Forum wiki page. Non-commercial users can get limited help with the installation process through Qt support. The primary support channel for commercial customers is their Qt Account.
