How to get the TableRow from TableView with given row Index.

Question

Hi ,
I want to retrieve the TableRow object or Cells of that row of the TableView, for the given row index. How i can get that.
Here is the below code what i am actually looking for
TableView table = new TableView();
table.getSelectionModel().selectedIndexProperty().addListener(new ChangeListener<Number>() {
     @Override
     public void changed(ObservableValue<? extends Number> paramObservableValue,Number prevRowIndex, Number currentRowIndex) {
          System.out.println(":::::::::>  Previous Row : "+prevRowIndex+" Current Row : "+currentRowIndex);
          if(prevRowIndex.intValue()>-1){
               // TODO: Get the TableRow object of prevRowIndex or the cells in that row.
});Thanks in advance !!

Answer 1

Jonathan, Thanks for the info !
Actually my requirement is ,
1) I have an editable table with four columns. Where the first three colums are editable and the last column is a delete button to delete the record.
2) My requirement is such that, whenever the user edits a cell, it is not comitted on focus out but the whole row(all cells) is comitted at a time when the user hits "enter". If the validation is not successfull, the textfields are styled with error class and focuses on it.
So based on the key event on the textfield in the editable cell, i am fetching all the cells in the same row, with the below code.. and doing the save/update operation.
textBox.setOnKeyReleased(new EventHandler<KeyEvent>() {
     @Override
     public void handle(KeyEvent t) {
          if (t.getCode() == KeyCode.ENTER) {
                      TableRowSkin<ContactPersonResponse> rowSkin = (TableRowSkin<ContactPersonResponse>) cell.getParent();
                ObservableList<Node> cells = rowSkin.getChildren();
                view.setCellAction(cells);
                      // The setCellAction(cells) will iterate through all the cells, validates the text field,
                      // if validation is success commits all the cells else styles the cells and focuses on the cell.
});Till now everything is fine and working properly.
Now I have new requirement that when the user edits a row (not yet comitted) and if he selects another row, the previous selected row should be automatically committed with validation.
So my final action is to call the setCellAction(cells) by passing the cells of the previous selected row.
table.getSelectionModel().selectedIndexProperty().addListener(new ChangeListener<Number>() {
     @Override
     public void changed(ObservableValue<? extends Number> paramObservableValue,Number prevRowIndex, Number currentRowIndex) {
          System.out.println(":::::::::>  Previous Row : "+prevRowIndex+" Current Row : "+currentRowIndex);
          if(prevRowIndex.intValue()>-1){
               // TODO: Need to call the setCellAction method by passing the cells of previous selected row. (prevRowIndex)
                        // Here i am not getting how to get the cells of the previous row.          
});In the selectedIndex listener , i am not getting how to get the cells/row from the index.
Any solution or workaround for achieving this functionality is highly apprieciated .
Thanks & Regards,
