I was speaking about these methods without keeping a reference to the Textboxs, like in full declarative syntax.
Stage {
    def tbIds = for(n in [0..<10]) "TextBox{n}";
    var vbox: VBox;
    scene: Scene {
        width: 100 height: 250
        content: [
            vbox = VBox {
                layoutX: 10
                layoutY: 10
                content: [
                    HBox {
                        content: [
                            Button {
                                text: "Set"
                                action: function() {
                                    for (id in tbIds) {
                                        //def tb = vbox.lookup(id) as TextBox;
                                        //Also work
                                        def tb = vbox.scene.lookup(id) as TextBox;
                                        tb.text = id
                            Button {
                                text: "Clear"
                                action: function() {
                                    for (id in tbIds) {
                                        def tb = vbox.lookup(id) as TextBox;
                                        tb.text = ""
                    for (id in tbIds) TextBox {id: id}
}
