我可以在不绑定每个小部件的情况下使用 window JavaFx 的大小调整场景大小吗？

Question

在我的应用程序中，我正在切换 fxml 文件以更改视图，因为我没有正确了解 Scene 和 Parent 根的概念。我所有的 fxml 文件都有一个 AnchorPane(600,400)。这就是我的启动方法的样子。

@Override
public void start(Stage primaryStage) throws Exception{
    Parent root = FXMLLoader.load(getClass().getResource("loginpage.fxml"));
    primaryStage.setTitle("Eye Ratina Scanner");
    primaryStage.setScene(new Scene(root, 600, 400));
    primaryStage.show();
}

这就是我改变看法的方式。

AnchorPane pane = FXMLLoader.load(getClass().getResource("../loginpage.fxml"));
        dashpane.getChildren().setAll(pane) //dashpane is AnchorPane

我将整个应用程序的大小设为 600:400。现在我希望当我单击 window 最大化按钮时，所有组件的大小都会调整得更大并保持比例不变。下面附上两张图片以显示正在发生的事情。when i click on maximize

normal 600:400 view

现在我不想绑定每个按钮、图像视图、锚定窗格、文本字段、标签等。这将花费太长时间，因为我有大约 42 个 fxml 文件。我们可以通过一个片段来实现我们的结果吗？我没有发现任何其他 post 有完全相同的问题。

感谢您提前回答。非常感谢您的帮助。

这是一个示例布局。它使用 VBox 作为根。它使用 AnchorPane。 AnchorPane里面是一个GridPane。您仍然需要努力使 ImageView 和 Label 文本随着 Stage 变大而变大。

我可以在不绑定每个小部件的情况下使用 window JavaFx 的大小调整场景大小吗？

Can i resize scene with the size of window JavaFx without binding each widget?

resize

javafx

stage
