TreeView moves its origin position if the root item has a parent

    XMLWordPrintable

    Details

      Description

      When a TreeItem that has a parent is set as the root node for a TreeView the x position of the root node is the same as if it was placed inside its parent.

      This code shows the behaviour:


      import java.util.*;

      import javafx.application.Application;
      import javafx.event.*;
      import javafx.scene.Scene;
      import javafx.scene.control.*;
      import javafx.scene.layout.VBox;
      import javafx.stage.Stage;

      public class TreeViewApp extends Application {

          static int pos = 0;

          public TreeViewApp() {
              // TODO Auto-generated constructor stub
          }

          public static void main(final String[] args) {
              Application.launch(args);
          }

          @Override public void start(final Stage stage) throws Exception {
              final VBox box = new VBox();
              final TreeView<String> view = new TreeView<String>();
              final List<TreeItem<String>> items = new ArrayList<TreeItem<String>>();
              for (int i = 0; i < 10; i++) {
                  final TreeItem<String> item = new TreeItem<String>("Item" + i);
                  item.setExpanded(true);
                  items.add(item);
              }
              for (int i = 0; i < 9; i++) {
                  items.get(i).getChildren().add(items.get(i + 1));
              }
              view.setRoot(items.get(0));

              final Button button = new Button("Shift");
              button.setOnAction(new EventHandler<ActionEvent>() {

                  @Override public void handle(final ActionEvent arg0) {
                      if (pos < 9) {
                          view.setRoot(items.get(++pos));
                      } else {
                          pos = 0;
                          view.setRoot(items.get(0));
                      }
                  }
              });
              box.getChildren().add(button);
              box.getChildren().add(view);
              stage.setScene(new Scene(box));
              stage.show();
          }
      }
