How do I get itemDoubleClick event in spark DataGrid ???

Question

Hello Everyone,
Recently I am working with Spark DataGrid.
Before I was using AdvancedDataGrid. In that I was capturing itemDoubleClick event.
But I am not able to find such a event in SparkdataGrid.
So I want to capture double click event on single row of DataGrid.
Some people told that, I have to use my custom ItemRenderer to do that.
But is there any way to capture itemDoubleClick event in Spark DataGrid without creating custom ItemRenderer ???

You are correct.  I looked a the code and the comment says it dispatches a double click if the 2nd click is within the  DOUBLE_CLICK_TIME even if the first click was on another cell.
This code figures out if the double-click is a true double-click.
