This question does not make much sense to me.

I have a GUI designed in QML. User is supposed to fill in some values there.
I am supposed to calculate something from those values and then pass them to C++ so that they can be used
in an algorithm.

You think this kind of problem cannot exist in a properly designed program?

Anyways,

I have found a temporary solution as follows:

One way to add the values dynamically to a 1 dimensional QML variant is to fill a normal Javascript array and then assign it to the QML variant.
Qt Code: 
  1. import QtQuick 2.0
  2.  
  3. Rectangle
  4. {
  5.     property variant oneDArray: []
  6.     MouseArea
  7.     {
  8.         anchors.fill: parent
  9.         onClicked:
  10.         {
  11.             var t = new Array (0)
  12.             t.push(11)
  13.             t.push(12)
  14.  
  15.             oneDArray = t
  16.  
  17.             console.log (oneDArray)
  18.         }
  19.     }
  20. }

  2. QML debugging is enabled. Only use this in a safe environment.
