当我在 SceneBuilder 上编辑时，程序看起来像这样 
当我运行该程序时，它看起来像这样:
这是我第一次尝试使用 FXML，我不知道出了什么问题。我试图关注this问题但没有看到解决方案..
这是我的 FXML 代码:

这是我的 Java 代码:
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.setScene(new Scene(root, 600, 400));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
对于大量的代码，我们深表歉意。只是不确定问题出在哪里。
最佳答案
您似乎只是将一些布局放在一起，使 UI 在 SceneBuilder 中看起来正确。
这种方法很糟糕。这样，您几乎可以确定调整大小时布局会变得困惑。如果调整Stage的大小，则会根据Stage的大小强制将Scene的内容调整为适当的大小。
您也可以在 SceneBuilder 中观察行为，如果将根节点包装在 AnchorPane 中，将原始根的所有 anchor 设置为 0 并调整 的大小> anchor Pane 。
您应该了解布局的作用，然后在 SceneBuilder 中设计 UI。一般来说，最好保持场景简单，而不是嵌套不必要的布局。
在您的情况下，3 Pane 似乎就足够了:
- 作为 root 的
GridPane - 包含
Button的VBox ScrollPane内的GridPane
通过使用 GridPane 的布局参数，您可以设计一个具有更好的调整大小行为的 UI:

关于java - SceneBuilder 看起来与 JavaFX 程序不同？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39847437/
