Getting Started with Qt

Downloading and Installing Qt

Qt framework and tools can be installed using an online installer, standalone binary installers or using source packages and building yourself. The open-source version is found from the Qt Project Downloads page, which contains download links for Qt and Qt Creator for different development platforms.

The commercial versions are available for free trial from Digia.

Installing with the Installation Program

The Qt Installation Program can download the Qt libraries and tools as well as the reference documentation and code samples. The Qt Installation Program page contains information about installation process.

Installing from the Qt Sources

Qt may also be installed from the sources. Simply download the sources (available from the Downloads page) and follow the instructions according to the development platform page here: Building Qt Sources.

Exploring the Tools

Qt Creator, the Qt IDE, integrates development tools such as a code editor, a UI designer, a debugger, and other project management tools such as version control.

For more information, these pages describe the tools and processes involved:

Creating Applications Using Qt

Qt 5's modularized nature means that modules may be omitted during the build process, producing libraries that are smaller in size and with less complexities. Depending on their support and target platforms, modules are either an essential or an add-on.

These pages explain the modules and the support level for different platforms:

To help you on your way, we created two tutorials creating two similar applications, but using different approaches. One implements the user interface using Qt Quick, while the other uses Qt Widgets.

Where to Go from Here

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 our API.

Qt's vibrant and active community site, houses a wiki, a forum, and additional learning guides and presentations.
