Qt Software Development

Q: What is the difference between the open-source and commercial licenses offered by the Qt framework?

The open-source Qt license ( GPLv2 , GPLv3 , LGPLv3 ) provides almost all APIs but some add-ons are available only under the commercial license . Besides, the commercial Qt license offers security tools and additional design tools for embedded development such as, for example, Qt for Device Creation. Under the commercial license, you get full support from the Qt company and take ownership of the development and distribution of your Qt-based product. However, the Qt distribution license is not perpetual and you will have to renew it.

Q: Why is Qt often preferred over other cross-platform frameworks?

Qt definitely has an edge over other frameworks due to a number of reasons. It offers different licensing options: you can use it under a commercial license and as an open-source technology. This framework and all its components are well-documented. Qt has its own IDE and is rich in ready-made libraries, development modules, and add-ons which makes it independent of external development tools. The QML language, premade widgets, and Qt design tools contribute a lot to the rapid and easy UI development. Qt is written in C++ which ensures the flexibility and speed of the development and enables developers to use a lot of C++ APIs and libraries. The Qt community is really large so you can always get the necessary expert assistance.

Q: Which alternative technologies do you use for cross-platform development?

Apart from Qt development services, we apply a variety of cross-platform frameworks, libraries, languages, and other development tools such as: GTK+ STL C/C++ Python Java C#/.NET

Q: I have a Qt-based desktop application and want to build a mobile version. Will the transition be easy?

The app porting shouldn't really be time consuming. It may require just some slight changes if there are no issues with the source code. GUI will not need any changes if the screen compatibility was initially taken into account. If not, our engineers will adapt your app according to the device requirements.

Q: Do you provide technical support for the application after the project is completed?

Yes, we do. We can provide customer support, not only during the warranty period but as long as you need it. Our consultants will be ready to give you online tech support on any issue.

We employ a broad range of tools to expand our opportunities in the cross-platform development of embedded, desktop, and mobile applications. The Qt framework serves this purpose perfectly well.

Integra Sources programmers use the Qt C++ framework to develop cross-platform applications using Qt Creator, Qt Quick, QML, and other Qt development tools.

What we do

We put our C++ expertise and skills in Qt development to create applications supported by all major embedded, desktop, and mobile operating systems. The Qt framework allows developing applications that can show equal performance on different hardware architectures. As a Qt development company, we are well-versed in Qt Creator, Qt Quick, QML, and other Qt development tools. We use all the advantages of Qt to design graphical user interfaces (GUIs) that facilitate user interaction with the device.

What's included?

We apply Qt software development services to projects that require platform compatibility and user interaction. We build mobile and desktop apps compatible with Android, iOS, Windows, Linux, macOS, and other open-source and commercial operating systems. We widely use Qt software development in embedded design. This tool is even more efficient for developing complex automation systems with human-machine interfaces (HMI). The Qt framework has a full line of its own development modules and add-ons, which makes Qt applications accessible on all platforms.

Embedded application development

We offer Qt app development to build software for embedded devices applied in a number of industries. Qt supports numerous hardware platforms and can run on either a small ARM (like Raspberry Pi) or a complex Intel processor.

GUI and HMI development

Using our proficiency in C++ and QML, we enhance the user experience by creating intuitive user interfaces for embedded system applications, desktop, console, and mobile apps. Qt is rich in technologies that make it possible to create an attractive UI design with diverse graphics, widgets, and visual effects.

Cross-platform development

Qt is a C++ framework highly compatible with operating systems based on different kernels and architectures. We use this advantage to write adaptable, reusable, and long-running code for cross-platform applications.

Mobile application development

Integra’s developers use Qt to create various mobile applications for smartphones and tablets based on both iOS and Android. Using Qt, we build custom apps from scratch and are able to port your existing application to the target mobile OS with slight changes or no changes at all.
