requestFocus

fun requestFocus(node: Node, useFocusTraversable: Boolean = false)

Give the input focus to node. Key events KeyEvent and KeyTypedEvent will be directed at node. See Node.onKeyPressed and Node.onKeyTyped.

node's Node.focusedProperty is set to true, and scene's focusOwner is set to node.

If useFocusTraversable == true (which is NOT the default), and node is not Node.focusTraversable, then the focus moves to the next focusTraversable Node. i.e. it is the same as a standard requestFocus followed by hitting Tab (or calling focusNext).

This is very handy if you have a container, such as VBox, and want the focus to go to the first descendant which is focusTraversable.
