Connect signal to slot programmatically in QML ?

Without evaluating the validity of the approach, Connections might do what OP is asking for.
Connections { target: root.dataRef function onValueChanged(key, value) { ... } }Edit: This seems to have already been discussed in https://forum.qt.io/post/740870

Signal objects have a connect() method to a connect a signal either to a method or another signal. When a signal is connected to a method, the method is automatically invoked whenever the signal is emitted. This mechanism enables a signal to be received by a method instead of a signal handler.
Eg:
Item { id: item onComponentCompleted: item.xChanged.connect(function(x) { console.log("x = " + x); }) }Asking a question about code? http://eel.is/iso-c++/testcase/

You should take a look at connect() function.
See this, https://stackoverflow.com/questions/53482999/qml-connect-signal-to-function

you can but not not sure it will work with
QQmlPropertyMap, since it is a bit of a magic type. -
