代码示例来源：origin: speedment/speedment

private void populateTree(ProjectProperty project) {
  requireNonNull(project);
  final TreeItem<DocumentProperty> root = branch(project);
  hierarchy.setRoot(root);
  hierarchy.getSelectionModel().select(root);
}

代码示例来源：origin: pmd/pmd

private void displayScopes(Node node, boolean focusScopeView) {
  // current selection
  TreeItem<Object> previousSelection = scopeHierarchyTreeView.getSelectionModel().getSelectedItem();
  ScopeHierarchyTreeItem rootScope = ScopeHierarchyTreeItem.buildAscendantHierarchy(node);
  scopeHierarchyTreeView.setRoot(rootScope);
  if (focusScopeView && previousSelection != null) {
    // Try to find the node that was previously selected and focus it in the new ascendant hierarchy.
    // Otherwise, when you select a node in the scope tree, since focus of the app is shifted to that
    // node, the scope hierarchy is reset and you lose the selection - even though obviously the node
    // you selected is in its own scope hierarchy so it looks buggy.
    int maxDepth = DesignerIteratorUtil.count(DesignerIteratorUtil.parentIterator(previousSelection, true));
    rootScope.tryFindNode(previousSelection.getValue(), maxDepth)
         .ifPresent(scopeHierarchyTreeView.getSelectionModel()::select);
  }
}
