Description
Why?
Cause
- Example use case: if tire-pressure change in all four wheels at the moment now each one need to be split to separated emits. After the change you would get this all once.
Customer
- ?
- Technically: more common use case than singleton also harder to work-around than singleton
Cruft
- No customer had wanted this since Qt 6.7, why would need it now?
What?
Definition
- Receive root object QML emits with multiple arguments by introducing a new signal management mechanism
