JavaFx未选择的TreeItem（TreeView）

Question

I made this treeView:

    TreeItem<String> root = new TreeItem<>("roothidden");
    treeView.setRoot(root);
    treeView.setShowRoot(false);


    mainModel.getNumberOfCnx();


    if(mainModel.getNumberOfCnx()!=0){

        // parcourir pr avoir tt les noms des cnx
        for(int i = 1 ; i<=mainModel.getNumberOfCnx() ; i++){

             String cnx = mainModel.getCnxName(i);
             TreeItem<String> node = new TreeItem<>(cnx,new ImageView(env_icon));

             // ajouter les param
             TreeItem<String> host_node = new TreeItem<>(mainModel.getCnxHost(cnx),new ImageView(host_icon));
             TreeItem<String> port_node = new TreeItem<>(mainModel.getCnxPort(cnx),new ImageView(port_icon));
             TreeItem<String> user_node = new TreeItem<>(mainModel.getCnxUser(cnx),new ImageView(user_icon));
             TreeItem<String> db_node = new TreeItem<>(mainModel.getCnxDbName(cnx),new ImageView(db_icon));

             node.getChildren().addAll(host_node,port_node,user_node,db_node);

             root.getChildren().add(node);
        }

and I want all of host_node, port_node, user_node and db_node can't be selected(and not disabled). How can I make it please?

Depending on what you try to achieve, I see three options:

1) Via the TreeTableViewSelectionModel as describe here: How to prevent TreeItem selection?

2) By using mouse transparent: treeView.setMouseTransparent(true)

3) By changing the selection colour to transparent via CSS
