import { VerticalBox , Button, LineEdit} from "std-widgets.slint";
export component Field inherits VerticalBox {
padding: 0;
in property <string> description;
in-out property <string> value;
}
export component TextField inherits Field {
Text { text: root.description; height: 20px; }
LineEdit { text <=> root.value; height: 30px; }
}
export component MainWindow inherits Window {

preferred-height: 300px;
in-out property <string> value;
VerticalBox {
Text { text: "Hi, Felix!"; height: 20px;}
TextField { description: "Do you like tea?"; value <=> value; }
TextField { description: "Your output is:"; value <=> value; }
Button { text: "Quit"; height: 30px; }
}
}
