Build Your World with Qt

Qt 5.5 brings you more solutions for even faster development workflows, a more powerful UI creation offering for keeping pace with market demands in multimedia and 3D user experiences, preliminary support for upcoming Windows 10 development, and more for connectivity. Plus, of course, improvements across the whole Qt framework.

All of this enhances the Qt cross-platform offering and the value it brings to executing successful desktop, multi-screen and connected device strategies with fast time-to-market without sacrifice to your user experience.

Qt Cinematic Experience 3D shows Qt 5.5. with the new Qt 3D technology preview, integrating Qt Multimedia features into a 3D user interface.

Meet the Qt Creator IDE

Ahead of the Rest

With Qt 5.5 our cross-platform libraries and professional tooling enables more code and UI design productivity than ever, in particular thanks to our updated integrated developer environment solution, Qt Creator 3.4.

Qt Creator is a modern IDE providing comprehensive tooling for cross-platform application development and device creation. Take a look at the workflow and features from this video.

Multimedia Integration

Qt 5.5 adds more convenience and power to the efficient handling of real-time camera or video processing. The Qt Multimedia module has received improvements that make it easier for integrating this technology into your Qt user interface.

On this short road trip, watch how Qt Multimedia with real-time video/camera integrates with the computer vision library (OpenCV) to create a real-time pattern recognition application that identifies speed signs along the road.

Qt3D Demo Game

Qt Technology Partner, V-Play Game Engine, already created a tech demo of what’s possible with Qt3D. This is what they had to say about their experience:

“Mixing 3D content with 2D elements has never been easier & faster in any programming language!”

Connect Your World

For your Internet of Things and connected device strategy, Qt 5.5 offers:


Full support for Bluetooth Low Energy (Bluetooth Smart) allowing you to easily write cross-platform code for communicating to your smart sensors, wearables or other BLE peripherals.


All you need for seamlessly integrating maps, reverse geocoding and navigation into your Qt applications with Qt Location. Be sure to check out the example apps, too.

Your Product on All Screens

At the heart of the Qt promise is the ability to have just one code base that can be reused across different operating systems & device types making Qt a future-proof strategic choice for your product development. With that being said, Qt 5.5 is ready for the upcoming Windows 10 release. We have been using Windows 10 pre-releases in development and will add support for Windows 10 with a Qt 5.5.x patch release once Windows 10 is available.
