QT Development

Since a Qt UI framework is based on C++, it brings high productivity. It has a comprehensive ecosystem of libraries and development tools that allow you to develop GUI applications with advanced data visualization and 3D object rendering on the fly. For example, Qt can be used for:

• UI-enabled smart home device ecosystems
• UI-enabled embedded systems
• Streaming systems, walkie-talkies, IPTV
• Computer utilities (e.g., calculators, text editors, players)
• Messengers
• Mobile and desktop clients (e.g., Google Drive, Facebook, Twitter)
• Graphic tool plugins
• Linux-driven UI-enabled apps

When used for an embedded device UI, ​Qt software requires just a screen resolution to start the development. It provides a ready-made lightweight environment that runs on a variety of supported hardware. The framework comes with a customizable software stack and special toolchain. Direct device deployment, on-device debugging, and profiling speed up the development process which reduces the time to market.

With Qt, your snappy UIs work on any screen and each platform as native. This is possible due to its APIs and modular structure. Additionally, the Qt Quick tool allows you to build dynamic UIs featuring fluid animation, transitions, and special effects.

A Qt UI is perfect for controlling IoT-connected devices. Their data stored in the Cloud can be accessed and managed from any gadget—a mobile phone, tablet, laptop, or PC. The UI you get is scalable and portable for each solution you add to the connected ecosystem.

Some projects don’t need a framework as multi-layered as Qt for building UIs. In this case, we suggest two other options:

• Web-view GUI—a tool that works on a device’s browser and uses Javascript. Instead of C++ engineers, you can therefore employ web developers to get a front-end UI. It also allows you to duplicate a UI for network devices so that you can reach it from any connected gadget. The drawback of this tool is a relatively large image footprint.
• Light and Versatile Graphics Library (LVGL)—a C-based library that helps create embedded GUIs. It’s perfect when a UI is all you need. LVGL demands a low memory footprint and a simpler license method. This makes it more convenient for designing plain UIs.

Softeq will help you choose a proper UI-building approach, be it a Qt framework or another development tool.
