Functions

nodePrefHeight

open override fun nodePrefHeight(): Float

Each subclass of node can determine its preferred height. 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.

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.
