Question

package application;

import java.awt.Button;

import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.StackPane;


public class Main extends Application {

    Button button;  //Declare Button

    public static void main(String[] args) {
        launch(args); //calls application 
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        //comes from application pack
        primaryStage.setTitle("Title Of Window"); //Main Stage
        button = new Button (); //Creates Button 
        button.setLabel("Click Me");

        StackPane layout = new StackPane();
        layout.getChildren().add(button); //Button in Scene
        Scene scene = new Scene (layout, 300, 250); //Sets Scene
        primaryStage.setScene(scene); //Stage and Scene
        primaryStage.show(); 



    }

嘿伙计们，所以这是我第一次在JavaFX中创建一些东西，我想知道为什么我的按钮在场景中没有添加Layout.GetChildren()行，它会继续在添加下方显示红线。我正在使用Eclipse IDE。

Answer 1

您已导入import java.awt.Button，您必须在javafx包中导入Button类。

为什么没有按钮添加到场景？
