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.

row

fun FormGrid.row(block: FormRow.() -> Unit? = null)

Add a FormRow to a FormGrid. e.g.

fun FormGrid.row(label: String, block: FormRow.() -> Unit? = null)

A very common convenience method when left is a label. This is equivalent to :

fun FormGrid.row(label: String, text: String, block: FormRow.() -> Unit? = null)

A convenience method for when you want a row with just a label on the left, and text on the right.
