If you make a change to the scene graph, the screen will automatically be refreshed.

To trigger the change, you use Behaviors, which are objects in the graph that get called when certain events happen: like a certain amount of time passing, or a change in the graph.

What exactly do you mean by "invalidate"?

"invalidate" means "refresh"
maybe i want to change a scene according to the item you selected from a combobox or your click on a botton
and so on.

There is nothing common about common sense

To do this quickly you could just detach the branch group associated with the cube and attach the branchgroup that contains the cone.  As most on this site will suggest, you will want to use a behavior to detect that someone clicked on the object but ofcourse you don't have to.
