Emitting a QObject signal FROM QML

RogueWarrior

Is it possible for QML to have a QObject emit a signal without needing a glue slot in the QObject that with then call emit MySignal?

For example, you click a QML button and you want that action to emit a signal that could be seen by QObjects. It seems like the only way to do this is have a slot somewhere which would then emit a QObject signal.

Signals from Item, QtObject, etc are QObject signals. There's no need to to have an intermediary.

just call the signal from QML, they are normal functions and are invokable from QML.

onClicked: yourCppObject.signal()

@GrecKo Thanks, but I think I'm running into a much deeper implementation question. I'm actually trying to emit a signal across a QRemoteObjects from the replica back to the source. I tried adding a test signal to my .rep file and calling it from the QML app which has the replica but nothing happens on the source side. I don't get any error messages or warnings on either end.

The only thing that does work is having a slot in the remote object that emits a signal. I can call that slot from QML and that gets handled on the source side. It's an ugly hack but it works.
