I\'m having some proble

Answer 1

I couldn't find method getPickResult in mouse event, so maybe next is preferable then answer from Alex:

1) add listener to tree view

treeView.getSelectionModel().selectedItemProperty().addListener((observable, oldValue, newValue) -> handle(newValue));

2) handle clicks, it's not need distinguish clicks on empty space and nodes

private void updateSelectedItem(Object newValue) {      
    System.out.println(newValue);
}
