Yes Qt is worth learning. Not only it's used a lot in C++ world, but also you can learn a lot of good architecture and OOP design in Qt, which is more valuable than Qt itself.
Simply so, should I learn QML?
In our experience, people are really quick to learn QML, especially those who already know JavaScript and some modern UI frameworks. They all agree, no matter the previous framework they used, that this is more natural and simplified way to write UI apps.
Furthermore, why is Qt not popular? With Xcode/Android Studio alone it's simply easier to start. C++ is considered to be a hard language. many people already know Java/Swift/JS but do not know C++, Qt or QML. Qt Commercial offering is unclear, weird, expensive and complicated.
In this manner, what is QML used for?
QML is a user interface specification and programming language. It allows developers and designers alike to create highly performant, fluidly animated and visually appealing applications.
Is QT easy to learn?
The overall development effort is minimal since Qt API are easy to understand and application functionality can be implemented with a smaller amount of code. C++ experts will find a lot of powerful APIs and tools in Qt which will make complicated things simple and new features easy to get done.
