我正在尝试学习JavaFX并在此视频中使用了代码:https://www.youtube.com/watch?v=FLkOX4Eez6o .
我有谷歌但无法找到解决方案 .
然后Eclipse IDE显示以下错误:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Testes extends Application{
Button botao;
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("Controle de processos");
botao = new Button();
botao.setText("+");
StackPane layout = new StackPane();
layout.getChildren().add(botao);
Scene cena = new Scene(layout, 300, 250);
primaryStage.setScene(cena);
primaryStage.show();
}
}
