Question

我在OSX上使用setMaximized（）方法遇到了麻烦，

当我调用它时：

Scene scene = new Scene(debug);

        stage.setOnCloseRequest(event -> System.exit(0));
        stage.setScene(scene);

        stage.setMaximized(true);
        stage.show();

应用程序窗口消失。为了澄清，我试图在OSX 10.9.5上运行Eclipse中的应用程序。相同的逻辑似乎在Windows上运行良好。是否有任何可能导致此问题的已知问题？我真的不想写我的窗口的平台特定实现。

编辑：这是整个班级：

public class Main extends Application {
    /** Pane that is used for outputting debug information about touch interactions and user interface elements. */
    private DebugParent debug;

    private Control customPane;

    private Stage stage;

    @Override
    public void start(Stage stage) throws Exception {
        Font.loadFont(this.getClass().getResourceAsStream("/ui/fonts/titillium.otf"), 20);

        customPane = FXMLLoader.load(this.getClass().getResource("/ui/Main.fxml"), null, new CustomBuilderFactory());

        customPane.dragProcessingModeProperty().set(EventProcessingMode.HANDLER);

        // Init Debug
        debug = new DebugParent(customPane);
        debug.registerCustomPane(customPane);
        debug.setOverlayVisible(false);

        // Init menu
        ContextMenu menu = new MainMenu(catalog, customPane);
        customPane.setContextMenu(menu);

        // Init scene
        Scene scene = new Scene(debug);

        this.stage = stage;
        this.stage.setOnCloseRequest(event -> System.exit(0));
        this.stage.setScene(scene);

        this.stage.setMaximized(true);
        this.stage.show();

        this.stage.addEventHandler(KeyEvent.KEY_PRESSED, this::handleKey);

        // Invalidate
        customPane.invalidate();
        customPane.requestFocus();
    }

    private void handleKey(KeyEvent keyEvent) {
        switch (keyEvent.getCode()) {
            case F10: stage.setMaximized(!stage.isMaximized()); break;
            case F11: stage.setFullScreen(!stage.isFullScreen()); break;
        }
    }

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

值得注意的是，我发现从这里尝试进入实际的全屏模式会完全崩溃Java。

从外观上看，JavaFX在OSX动画方面表现不佳。

我不知道为什么setMaximized（）不能在OS X上工作但是这是围绕这项工作的一些工作：您可以尝试获取VisualBounds的宽度和高度并使用它。

Scene scene = stage.getScene();
Screen primaryScreen = Screen.getPrimary();
Rectangle2D visualBounds = primaryScreen.getVisualBounds();
double width = visualBounds.getWidth();
double height = visualBounds.getHeight();
scene = new Scene(root, width, height);

Javafx setMaximized on OSX
