JavaFX tab through editable cells - javafx

Question

I have defined my own editable cell for a TableView. Everything works great but I want to be able to tab through the cells. Say I'm in cell [2,2] on a tab press I want the selected cell to go to [3,2]. Is this possible? How should I go about achieving this? Should I add a listener to the TableCell or the TableColumn?
Here is my custom TableCell
class EditingCell extends TableCell<Student, String> {
private TextField textField;
public EditingCell(Assignment assign) {
this.setTooltip(new Tooltip(assign.getMaxPoints() + " pts max"));
}
#Override
public void startEdit() {
if (!isEmpty()) {
super.startEdit();
createTextField();
setText(null);
setGraphic(textField);
textField.selectAll();
}
}
#Override
public void cancelEdit() {
super.cancelEdit();
setText((String) getItem());
setGraphic(null);
}
#Override
public void updateItem(String item, boolean empty) {
super.updateItem(item, empty);
if (empty) {
setText(null);
setGraphic(null);
} else {
if (isEditing()) {
if (textField != null) {
textField.setText(getString());
}
setText(null);
setGraphic(textField);
} else {
setText(getString());
setGraphic(null);
}
}
}
private void createTextField() {
textField = new TextField(getString());
textField.setMinWidth(this.getWidth() - this.getGraphicTextGap()* 2);
textField.focusedProperty().addListener(new ChangeListener<Boolean>(){
#Override
public void changed(ObservableValue<? extends Boolean> arg0,
Boolean arg1, Boolean arg2) {
if (!arg2) {
commitEdit(textField.getText());
}
}
});
}
private String getString() {
return getItem() == null ? "" : getItem().toString();
}
}

You can achieve this by adding a KeyListener to your textField. Try adding the following code to your createTextField()
textField.setOnKeyPressed(new EventHandler<KeyEvent>() {
#Override
public void handle(KeyEvent t) {
if (t.getCode() == KeyCode.ENTER) {
commitEdit(Integer.parseInt(textField.getText()));
} else if (t.getCode() == KeyCode.ESCAPE) {
cancelEdit();
} else if (t.getCode() == KeyCode.TAB) {
commitEdit(Integer.parseInt(textField.getText()));
TableColumn nextColumn = getNextColumn(!t.isShiftDown());
if (nextColumn != null) {
getTableView().edit(getTableRow().getIndex(), nextColumn);
}
}
}
});
There are a few more things that you will have to take care of. For a complete example, please follow
