搜索并找到 TreeItem 后，我可以滚动到 TreeView 中的选定项目吗？ (JavaFX)

Question

I have a TreeView with numerous TreeItems in it. I have built a search function that works and selects the TreeItem specified but the TreeView scroll function does not scroll to it so one has to do it by hand which is not convenient at all. Is there a way to scroll automatically to the node (TreeItem) in some way after the search has successfully finished?

Code for search function:

@FXML
private void searchButtonEvent(ActionEvent event) {
    TreeItem<String> rootItem = treeView.getRoot();
    String textFieldText;
    boolean flag = false;

    textFieldText = textField.getText();
    searchStatus.setText("");

    if (textFieldText.equals("")) {
        searchStatus.setText("Please enter something to be searched");
    } else {
        for (int i = 0; i < 2; i++) {
            for (TreeItem<String> treeItem : rootItem.getChildren().get(i).getChildren()) {
                if (treeItem.getValue().contains(textFieldText)) {
                    treeView.getSelectionModel().select(treeItem);
                    searchStatus.setText("");
                    flag = true;
                } else {
                    if (!flag) {
                        searchStatus.setText("Not found");
                    }
                }
            }
        }
    }
}

I suppose that might be a method just after

treeView.getSelectionModel().select(treeItem);

that might do the work.

Found the solution finally:

@FXML
private void searchButtonEvent(ActionEvent event) {
    TreeItem<String> rootItem = treeView.getRoot();
    String textFieldText;
    boolean flag = false;
    int count = 0;

    textFieldText = textField.getText();
    searchStatus.setText("");

    if (textFieldText.equals("")) {
        searchStatus.setText("Please enter something to be searched");
    } else {
        for (int i = 0; i < 3; i++) {
            for (TreeItem<String> treeItem : rootItem.getChildren().get(i).getChildren()) {
                count++;
                if (treeItem.getValue().contains(textFieldText)) {
                    treeView.getSelectionModel().select(treeItem);
                    treeView.scrollTo(count);
                    searchStatus.setText("");
                    flag = true;
                } else {
                    if (!flag) {
                        searchStatus.setText("Not found");
                    }
                }
            }
        }
    }
}

Method was in TreeView Class named scrollTo(int) so I just had to add a counter for that
