How to make the window non-resizable while automatic layout is enabled?

[peterjc123]

Alternatively, can I get the current width and height of the widgets under automatic layout?

You can use the width and height properties of the window to make it fix, and the preferred-width / preferred-height properties of a layout to know the size it would have.

So I think you want something like this:

export component Demo {
    height: layout.preferred-height;
    width: layout.preferred-width;
    layout := VerticalBox {
        Text { text: "Hello World!"; }
        TextEdit { }
        Button { text: "Ok"; }
    }
}
