推荐答案

您可以使用静态方法 getRowIndex() 和 getColumnIndex() 位于 GridPane 类中.

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));
