verticalLayout {
            button("Delay").onClick {
                log("click begin")
                launch(JavaFx) { //or launch(yourUIFrameworkDispatcher)
                    log("delay begin")
                    delay(30000L)  
//                    Thread.sleep(30000L)
                    log("delay end")
                }
                log("click end") //note this will go off before "delay end" does
            }
        }
