使用JavaFx开发windows界面程序入门

1、下载JavaFx

JavaFX下载 | JavaFX中文官方网站

2、解压到windows目录

3、添加环境变量

PATH_TO_FX  D:\program\javafx-sdk-17.0.14\lib

4、Idea配置库，勾选fx的lib目录

5、添加VM option

--module-path "D:\program\javafx-sdk-17.0.14\lib" --add-modules javafx.controls,javafx.fxml -Djavafx.platform=headless 

创建这个项目选择FX app

6 、Main代码

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setResizable(true);
        primaryStage.setScene(new Scene(root, 300, 275));
        primaryStage.show();
    }


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

7、pom.xml代码
