SubMenu

class SubMenu(text: String, graphic: Node? = null) : LabelledMenuItem, WithItems

A type of MenuItem, which displays a PopupMenu when it is hovered over. The PopupMenu is populated from items.

nodePrefWidth

open override fun nodePrefWidth(): Float

Each subclass of node can determine its preferred width. As most nodes are composed of smaller nodes, this is typically calculated using evalPrefWidth of the child nodes, with extra added for spacing, padding and borders.
