return bind 式 という書き方ができるのか
import javafx.ui.*; public class Tesuto2 { attribute x:String; attribute y:String; operation goukei():String ; } operation Tesuto2.goukei():String { return bind "{x}と{y}."; } var tes = Tesuto2 {x:"山" y: "川"}; var win = Frame { title: bind " JavaFX" width: 200 height:150 content: GridPanel { rows:2 columns:1 cells: [ TextField { value: bind tes.goukei() // *B }, TextField { value: bind tes.x } ] } visible: true };
