Answer 1

A stage是javafx-2中的一個窗口。它提供hide和show方法：

import javafx.application.Application; 
import javafx.event.ActionEvent; 
import javafx.event.EventHandler; 
import javafx.scene.Scene; 
import javafx.scene.control.Button; 
import javafx.scene.control.Label; 
import javafx.scene.layout.HBox; 
import javafx.stage.Stage; 

public class HideShowApp extends Application { 
    public static void main(String[] args) { 
     launch(args); 
    } 
    @Override 
    public void start(Stage stage) throws Exception { 
     final Stage window = new Stage(); 
     window.setX(10); 
     Scene innerScene = new Scene(new Label("inner window")); 
     window.setScene(innerScene); 

     HBox root = new HBox(10d); 
     Button showButton = new Button("show"); 
     showButton.setOnAction(new EventHandler<ActionEvent>() { 
      @Override 
      public void handle(ActionEvent event) { 
       window.show(); 
      } 
     }); 
     Button hideButton = new Button("hide"); 
     hideButton.setOnAction(new EventHandler<ActionEvent>() { 
      @Override 
      public void handle(ActionEvent event) { 
       window.hide(); 
      } 
     }); 
     root.getChildren().add(showButton); 
     root.getChildren().add(hideButton); 
     stage.setScene(new Scene(root)); 
     stage.show(); 
    } 
}
