Hello ravidavi, Thank you for your your answer.
What you suggest can be accomplish by the use a visitor or a callback?: Lets say that I want to change show/hide the text when the user press a key, moreover, if some of the text for nodes (cessna) should be shown/hidden with some key and others (glider) with another. And at the same time, each text varies in time (like if they were their positions)...How can I accomplish this?
