Hi
I am using Enterprise Version of Qt.I have this tumbler in controls which works as expected in normal cases i.e., if we pass any static model to it it works. But When Component is loaded i want to change current index value of Tumbler to some Value. Here my code is as :

Qt Code: 
  1. Tumbler {
  2.             id: _yearTumbler
  3.             height: 200 
  4.             TumblerColumn {
  5.                 id: _yearColumn
  6.                 model:_yearModel   //model contain values from 2000 to 2100
  7.             }
  8.         } 
  9.        Component.onCompleted:{
  10.             _yearTumbler.setCurrentIndexAt(0,16);  // i need to set 2016 as curent Value.
  11.        }
To copy to clipboard, switch view to plain text mode 

I feel value is set in model but not physically.(Tumbler does not move on settibng values)
Pls suggest some inputs
