Something that would, I think, boost the usage of the designer is to skip the "recompilation" part and just have something that scans your code and interprets the C++ instead of compiling it, with something like https://github.com/RuntimeCompiledCPlusPlus/ RuntimeCompiledCPlusPlus . You would just add some metadata to your Widget with Q_CLASSINFO("DesignerName", "My widget"), the code looks for classes with this specific key, "compiles" it and adds it to the designer.
