Javafx: Adjusting TreeView with right order - javafx

Question

Here is a TreeView in which User can add tree items like Roots and its Coordinates.
Problem is all newly added Roots have same rectangles generated by Coordinates. Every root should have its own result not same from other Roots. For this do i have to assign index for every root so that it has its own result?
public class Main extends Application
{ public static void main(String[] args)
{launch(args);}
static final Map<TreeItem<String>, BorderPane> map = new HashMap();
#Override
public void start(Stage primaryStage)
{
BorderPane root = new BorderPane();
TreeItem<String> tree = new TreeItem<String>("Main System");
TreeItem<String> item1 = new TreeItem<String>("Roots");
TreeView<String> treeView = new TreeView<String>(tree);
treeView.setOnMouseClicked((event)->{
TreeItem<String> TreeItem = (TreeItem<String>)treeView.getSelectionModel().getSelectedItem();
if(TreeItem.getValue().equals("Roots"))
{
root.setCenter(getRootsPanel());
}
else
{
root.setCenter(map.get(TreeItem));
}
});
treeView.setCellFactory(new Callback<TreeView<String>,TreeCell<String>>(){
#Override
public TreeCell<String> call(TreeView<String> p) {
return new AddMenuTreeCell();
}
});
tree.setExpanded(true);
root.setLeft(treeView);
tree.getChildren().add(item1);
Scene scene = new Scene(root, 700, 500);
primaryStage.setTitle("Tree View");
primaryStage.setScene(scene);
primaryStage.show();
}
TreeItem<String> addNewTreeItem(String name){
TreeItem TreeItem = new TreeItem(name);
return TreeItem;
}
private static class AddMenuTreeCell extends TextFieldTreeCell<String> {
private ContextMenu menu = new ContextMenu();
private TextField textField;
public AddMenuTreeCell() {
MenuItem newitem1 = new MenuItem("Insert Roots");
MenuItem newitem2 = new MenuItem("Insert Coordinates");
menu.getItems().addAll(newitem1,newitem2);
newitem1.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent arg0) {
TreeItem<String> item3 = new TreeItem<String>("Roots");
// item3.getChildren().clear();
getTreeItem().getChildren().add(item3);
}
});
newitem2.setOnAction(new EventHandler<ActionEvent>() {
#SuppressWarnings("unchecked")
#Override
public void handle(ActionEvent arg0) {
TreeItem<String> newLeaf = new TreeItem<String>("Coordinates");
TreeItem<String> uxItem1 = new TreeItem("X");
map.put(uxItem1, getrightPane1());
TreeItem<String> uyItem1 = new TreeItem("y");
map.put(uyItem1, getrightPane1());
newLeaf.getChildren().addAll(uxItem1,uyItem1);
getTreeItem().getChildren().add(newLeaf);
}
});
}
#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(item);
}
setText(null);
setGraphic(textField);
} else {
setText(item);
setGraphic(getTreeItem().getGraphic());
if (!(getTreeItem().isLeaf() && getTreeItem().getParent() == null)){
setContextMenu(menu);
}
}
}
}
}
private static BorderPane getrightPane1() {
TextField textf1 = new TextField();
TextField textf2 = new TextField();
BorderPane root1 = new BorderPane();
VBox vbox = new VBox(20);
vbox.setPadding(new Insets(10));
HBox h1 = new HBox(7);
HBox h2 = new HBox(7);
textf1.setPrefWidth(100);
textf1.setPromptText("Enter Height");
textf1.setOnKeyReleased(new EventHandler<KeyEvent>(){
#Override
public void handle(KeyEvent event)
{
if(textf1.getText().length() > 0 && textf2.getText().length() > 0)
{
Rectangle rect1 = new Rectangle();
rect1.setHeight(Double.parseDouble(textf1.getText()));
rect1.setWidth(Double.parseDouble(textf2.getText()));
rect1.setFill(null);
rect1.setStroke(Color.RED);
root1.setCenter(rect1);
}
}
});
textf2.setPrefWidth(100);
textf2.setPromptText("Enter Width");
textf2.setOnKeyReleased(new EventHandler<KeyEvent>(){
#Override
public void handle(KeyEvent event)
{
if(textf1.getText().length() > 0 && textf2.getText().length() > 0)
{
Rectangle rect2 = new Rectangle();
rect2.setHeight(Double.parseDouble(textf1.getText()));
rect2.setWidth(Double.parseDouble(textf2.getText()));
rect2.setFill(null);
rect2.setStroke(Color.RED);
root1.setCenter(rect2);
}
}
});
if(textf1.getText().length() > 0 && textf2.getText().length() > 0 && root1.getCenter() == null)
{
Rectangle rect = new Rectangle();
rect.setHeight(Double.parseDouble(textf1.getText()));
rect.setWidth(Double.parseDouble(textf2.getText()));
rect.setFill(null);
rect.setStroke(Color.RED);
root1.setCenter(rect);
}
h1.getChildren().addAll(new Label("Y1:"), textf1);
h2.getChildren().addAll(new Label("X1:"), textf2);
vbox.getChildren().addAll(h1, h2);
root1.setLeft(vbox);
return root1;
}
private static BorderPane getRootsPanel() {
BorderPane root2 = new BorderPane();
HBox hbox = new HBox(10);
hbox.setPadding(new Insets(40));
hbox.setAlignment(Pos.TOP_CENTER);
List<BorderPane> listBordePane = new ArrayList(map.values());
for(BorderPane element : listBordePane)
{
Node node = element.getCenter();
if(node instanceof Rectangle)
{
Rectangle rect1 = ((Rectangle)node);
Rectangle rect2 = new Rectangle();
rect2.setWidth(rect1.getWidth());
rect2.setHeight(rect1.getHeight());
rect2.setFill(rect1.getFill());
rect2.setStroke(rect1.getStroke());
Platform.runLater(()->{hbox.getChildren().add(rect2);});
}
}
Platform.runLater(()->{root2.setLeft(hbox);});
return root2;
}
}
Note: if use clear() to clean every root, it would cause issue for this problem,
" let suppose user has main root in which there are 2 sub roots with 1 coordinate each. so each sub root show 2 rectangles in horizontal order and Main root will have 4 rectangles in horizontal order".
Any idea will be helpful please. Thank you
