C++Builder and C++ Qt/QML are both powerful integrated development environments (IDEs) for creating desktop and mobile applications using the C++ programming language. While they share many similarities, they also differ in some key ways.
- Both support the C++ programming language: Both C++Builder and C++ Qt/QML allow you to write your applications using the C++ programming language.
- Both are powerful IDEs: Both environments provide a wide range of tools and features to make development easier, including code editors, debuggers, and compilers.
- Both support cross-platform application development: You can use C++Builder and C++ Qt/QML to create applications that run on a variety of operating systems, including Windows, macOS, Linux, Android, and iOS.
- Development environment: C++Builder has a sophisticated editor for creating programs on all known systems, but this environment is only available on Windows, while Qt has a sophisticated editor and graphical tools for development on Windows, Mac, and Linux.
- Programming approach: Qt uses two types of technologies to create programs: the old Qt Widgets method, which is based entirely on pre-built components for direct use and is designed for object-oriented programming in C++ (this is only for desktop applications), and a new method that started in 2012 using a language similar to JavaScript to configure graphical components. This method is more advanced and uses JavaScript in all its parts, and it supports mobile applications, 2D and 3D programs, and any type of software. This language, called QML, is linked to the main C++ program and interacts directly with it through an engine that connects them.
- C++Builder, on the other hand, relies on object-oriented components designed for interface development with a large set of ready-to-use tools and uses an old library called VCL that only works on Windows. In 2012, it released a new multi-platform library called FireMonkey (FMX for short). This library allows you to design programs on Windows, Linux, Mac OS, Android, and iOS.
- Qt also supports translation to Webassembly, while C++Builder does not support this yet.
- Performance: C++Builder is known for offering faster performance than C++ Qt/QML, especially when creating desktop applications.
- Community: C++ Qt/QML has a larger and more active community than C++Builder, which means there are more resources available and more support.
- C++Builder is a good choice if you are looking for an easy-to-use IDE with a wide range of ready-to-use components. It also offers faster performance than C++ Qt/QML.
- C++ Qt/QML is a good choice if you are looking for a more flexible IDE that allows you to create dynamic and flexible user interfaces. It also has a larger and more active community.
Ultimately, the best IDE for you will depend on your specific needs and requirements.

7 个月A well reasoned summary of two very mature and competitive frameworks, both of which I have experience. The main cross platform Qt IDEs are known as Qt Creator and Qt Design Studio for the record, amongst many other minor UI and command line tools for design, productivity and workflow efficiency on all platforms. QML is indeed its own language and recent advances in the Qt Framework tooling (qmlsc) mean that QML and the well formed JavaScript that it may choose to use, runs with a performance comparable to C++ since for a large part, it can compile your wonderful declarative interfaces to C++ directly. Should you wish to develop with QML in your other favourite IDE you may consider using the QML Language Server Protocol also. The equivalent of VCLs are also available from third parties or it is easy to develop your own - all HW accelerated of course.
