IDEA下开发JavaFx Application

New > project > JavaFx Application

添加SceneBuilder

下载SceneBuilder

file | setting > JavaFx > add path

设置自定义图标

primaryStage.getIcons().add(new Image("file:res/internet.png"));

打包生成exe

File | project structure > Artifacts > JavaFx >(class | title | Navite Bundle)

注意目录文件要能找到

事件绑定

fxml

onAction add

Java

添加函数

fx:id 对象属性修改

添加一个fxml成员变量

调用setText("");

我的代码
