Do Qt replica slot functions work with references?

majorRonk

I wondering if its possible to use references in .rep files,
so that the reference value is changed in the host function
and the replica site gets the new value.
I guess the value is dropped while transfer, right ?

SLOT(QVariant readValue(QString key, QString section, bool& found))

It does not seem to work. "found" is always false, after its set to true on the host site.

Hi,

Don't do that. Signals and slots are not made for that use case. During asynchronous connections, parameters are copied.

Yes, it's possible, but references in .rep files typically don't persist during transfer. Use return values, state management, or callbacks to ensure the replica site gets the updated value.
