RigidArea

Empty space of a fixed size, width by height - the rigid area of Box.createRigidArea.

Its minimum, preferred and maximum size are all that size, so a PanelLayout.Box panel or a ToolBar holds it at exactly that size - which is what makes it the gap between two items:

Panel(PanelLayout.Box(axis = BoxLayout.X_AXIS)) {
    Button(text = "Cancel", onClick = { ... })
    RigidArea(width = 8, height = 0)
    Button(text = "OK", onClick = { ... })
}
