    @Override
    public void handle(MouseEvent e) {

Answer 1

You can get the row index and column index by utilising the static methods getRowIndex() and getColumnIndex() which are located in the GridPane class.

System.out.println("Row: " + GridPane.getRowIndex(text1));
System.out.println("Column: " + GridPane.getColumnIndex(text1));

See for the reference.

can i get index without getting add any node on grid pane – Cynthea

The method GridPane.getColumnIndex(text1) or GridPane.getRowIndex(text1) will not add any node on the GridPane. It just returns the index of the passed item. – Murther

Answer 2

When i was looking for the same answer as OP I searched a lot and eventually found this.

GridPane.getColumnIndex((Node) e.getTarget());

GridPane.getRowIndex((Node) e.getTarget());

It works to get the index in an Integer format by clicking on the Node you want the coordinates from if you are using a GridPane to make your "Grid"
