彈窗啟動(dòng)類

package cn.zxl.AlertWindow;import javafx.application.Application; import javafx.geometry.Pos; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.layout.VBox; import javafx.stage.Stage;/*** @Description: //TODO 主類* @Author: zhangxueliang* @Create: 2021-05-27 09:50* @Version: 1.0**/ public class Main extends Application {@Overridepublic void start(Stage primaryStage) throws Exception {Button btn = new Button("彈出窗口");btn.setOnMouseClicked(event -> {System.out.println(AlertWindow.display("新窗口", "是否關(guān)閉窗口"));});VBox vBox = new VBox();vBox.getChildren().add(btn);//設(shè)置居中顯示vBox.setAlignment(Pos.CENTER);Scene scene = new Scene(vBox, 400, 400);primaryStage.setTitle("彈出窗口示例");primaryStage.setScene(scene);primaryStage.show();}public static void main(String[] args) {launch(args);} }

最終效果

單擊彈出窗口按鈕會(huì)彈出新窗口。

消息對(duì)話框

彈窗類

同上。

消息對(duì)話框啟動(dòng)類

package cn.zxl.AlertWindow;import javafx.application.Application; import javafx.geometry.Pos; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.layout.VBox; import javafx.stage.Stage;/*** @Description: //TODO 消息提示框* @Author: zhangxueliang* @Create: 2021-05-27 09:50* @Version: 1.0**/ public class Main2 extends Application {Stage stage;@Overridepublic void start(Stage primaryStage) throws Exception {stage = primaryStage;//單擊系統(tǒng)自帶的關(guān)閉按鈕時(shí)也要彈出詢問(wèn)窗口stage.setOnCloseRequest(event -> {//點(diǎn)擊了否,也會(huì)關(guān)閉窗口，所以要取消默認(rèn)事件,單擊否按鈕不會(huì)關(guān)閉窗口event.consume();closeWindow();});Button btn = new Button("關(guān)閉窗口");btn.setOnMouseClicked(event -> closeWindow());VBox vBox = new VBox();vBox.getChildren().add(btn);//設(shè)置居中顯示vBox.setAlignment(Pos.CENTER);Scene scene = new Scene(vBox, 400, 400);stage.setTitle("彈出窗口示例");stage.setScene(scene);stage.show();}/*** //TODO 如果點(diǎn)擊了是按鈕，就關(guān)閉所有窗口* @Description: * @Create: 2021/5/27 10:59* @Author: zhangxueliang* @Param:* @Return: */private void closeWindow() {boolean b = AlertWindow.display("新窗口", "是否關(guān)閉窗口");if (b) {stage.close();}}public static void main(String[] args) {launch(args);} }

最終效果

單擊是關(guān)閉窗口，單擊否不關(guān)閉。
并且單擊X按鈕效果一樣。
