Ok, I was just checking regarding to the old code where it was:

  property int nbSelectorColumns: horizontal ?
                                                      Activity.selectorLayout[nbItems][0] :
                                                      Activity.selectorLayout[nbItems][0] / 2

so I expected it to be twice the same.
Note that it is about the nbSelectorColumns and the condition is on the layout, it is not related to any row.
