I declared a QML element using @QmlElement, but it is not recognized by Qt Design Studio, even though the program runs fine and the functionality seems to be working correctly, but it cannot be recognized by QDS.

What else can I do? Or can the official provide a complete small example of how pyhton and QDS work together? 

Or tell me if I am developing desktop applications using pyside+qml, can I use QDS? Or QDS is not suitable for co-development with pyside, very confused, looking forward to a reply
