javafx如何实现模态/模式对话框

来源：互联网发布：销售数据分析怎么写编辑：程序博客网时间：2024/06/03 11:05

注：打开的模式对话框内是一个嵌套的html页面。（个人需求，和模式对话框没什么关系）
一、模式对话框代码：

import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.concurrent.Worker;
import javafx.concurrent.Worker.State;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.paint.Color;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Modality;
import javafx.stage.Stage;

public class ModalDialog extends Application {
   /**
   * 网页地址
   */
   private String url;

   public ModalDialog(final Stage stg, String url) {
       this.url = url;
       final Stage stage = new Stage();
       // Initialize the Stage with type of modal
       stage.initModality(Modality.APPLICATION_MODAL);
       // Set the owner of the Stage
       stage.initOwner(stg);
       stage.setTitle("Top Stage With Modality");
       Group root = new Group();
       Scene scene = new Scene(root, 300, 250, Color.LIGHTGREEN);
       stage.setScene(scene);
       stage.setTitle("测试页面");
       try {
           start(stage);
       } catch (Exception e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
       stage.show();
   }

   @Override
   public void start(Stage stage) throws Exception {
       // TODO Auto-generated method stub
       stage.setWidth(600);
       stage.setHeight(700);
       stage.setTitle("测试页面");
       Scene scene = new Scene(new Group());
       final WebView browser = new WebView();
       final WebEngine webEngine = browser.getEngine();
       ScrollPane scrollPane = new ScrollPane();
       scrollPane.setContent(browser);
       webEngine.getLoadWorker().stateProperty().addListener(new ChangeListener<State>() {
           @Override
           public void changed(ObservableValue ov, State oldState, State newState) {
               if (newState == Worker.State.SUCCEEDED) {

               }

           }
       });
       webEngine.load(url);
       scene.setRoot(scrollPane);
       stage.setScene(scene);
       stage.show();
   }

}

二、调用代码：
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.paint.Color;
import javafx.stage.Stage;

public class ModalTest extends Application {
   /** * @param args the command line arguments */
   public static void main(String[] args) {
       Application.launch(ModalTest.class, args);
   }

   @Override
   public void start(final Stage primaryStage) {
       primaryStage.setTitle("Hello World");
       Group root = new Group();
       Scene scene = new Scene(root, 900, 700, Color.LIGHTBLUE);
       Button btn = new Button();
       btn.setLayoutX(250);
       btn.setLayoutY(240);
       btn.setText("Show modal dialog");
       btn.setOnAction(new EventHandler<ActionEvent>() {
           public void handle(ActionEvent event) {
            ModalDialog md = new ModalDialog(primaryStage,"www.baidu.com");
           }
       });
       root.getChildren().add(btn);
       primaryStage.setScene(scene);
       primaryStage.show();
   }
}
