splitPane change listener

[Bene Volent]

How to implement a change listener for a splitPane?

Having doubts based on some practices, which do not seem to work this far.

def dvListener (splitp:SplitPane) {
  // "Cannot resolve overloaded method addListener"    
  splitp.dividers.addListener {
    (o: javafx.beans.value.ObservableValue[_ <: Number], oldVal: Number, newVal: Number) => {
      // conditions to capture the variation or whatever
      val divposit = newVal
      if ... {
        println("Position changed:" + divposit)

        ...

        ...
      }
    }
  } // end addListener
}  // END dvListener

Issue seems to be with implementation of addListener. What am I missing?

thanks.

You can treat dividers as an ObservableBuffer and use onChange to listen to changes:

splitp.dividers.onChange{ (buffer, changes) =>
  ...
}

There is a complete example here:

Thanks, it is good to see a complete implementation in that example.
