And the lack of familiarity of individual users with QT also limits the use of QT in the enterprise space. In the enterprise world, people prefer to use stable and reliable products. At this time Microsoft's VisualStudio+Windows combo was dominant in the enterprise GUI (GUI, not web or other) market. A large number of embedded systems on the computer, to engage in the complexity of the application software are using this combination. What advantage does QT have here? Cross-platform? The problem is that this field basically does not consider cross-platform. For example, color ultrasound, these medical equipment is packaged for sale, the customer is not possible to replace the system and there is no way to replace the system. For example, the power plant monitoring system and other industry software, are also the same. There is basically no cross-platform needs. More need for stable suppliers, powerful features, low cost (development costs and maintenance costs, the cost of development tools can be ignored), stability and better user-friendliness. QT is not suitable for any of these. The main thing is that QT has not developed a large number of engineers who are inclined towards QT, so QT is naturally not a priority.
