Did we need manually program QT Quick on C++ side for complex & very dynamics UI

[Misko Lee]

Hi:

I want to talk did we need manually program QT Quick on the C++ side for performance reasons.

I am working a cross-platform DAW software like: Cubase / Cubasis

Cubase - Desktop

Cubasis - Mobile

I think the Cubase build with QT Widgets and the cubasis from qt quick. Did anyone kowns the cubasis how to using QT Quick, 100% QML or combine with C++?

If our application need:

1. a lots small items. such as that piano roll component.
2. very dynamics insert / remove items.
3. ** a lots item need handler events(mouse / touch / keyboard) **.

can we 100% QML for that?
