Default width/height for Horizontal/VerticalLayout?

[aurexav]

How to do this?

HorizontalLayout {
        Rectangle {
            width: foo.bar ? 0 : $DEFAULT;
        }

        Rectangle { }

        foo := Rectangle {
            out property <bool> bar;
        }
}

You can try something like this:

        Rectangle {
            max-width: foo.bar ? 0 : 10000;
        }

It would be better to have such built-in keyword to avoid using the magic number.
