全屏阶段在JavaFX 2.1中无法正常工作？ [英] Fullscreen stage is not working properly in JavaFX 2.1?

问题描述

我加载它的第一个阶段总是以全屏方式正常打开。

The first stage that I load it always open properly as fullscreen.

stage.setFullScreen(true);
stage.setScene(login_scene); 

但当我换到另一个FXML时，应用程序保持全屏（没有顶部工具栏..），但是实际视图内容在FXML的根AnchorPane的prefWidth / prefHeight上调整大小（我可以在右下角看到桌面：|），我希望它对我的屏幕分辨率是动态的。

But when I change to another FXML the applications stays fullscreen (no top toolbar.. ), but the actual view content gets resized on the prefWidth/prefHeight of the root AnchorPane from FXML (I can see the desktop in my bottom right corner :|), and I want it to be dynamic to my screen resolution.

谢谢。

@Later编辑：

所以在start方法中我的主要类I加载一个Scene（从FXML doc创建）并将其设置为Stage（start方法参数）。我保存这个阶段供以后使用。

So on the start method of my main Class I load a Scene (created from an FXML doc) and set it to the Stage (the start method param). I save this stage for later use.

当我按下具有相同阶段的按钮时，我先保存，然后将场景更改为另一个FXML文档

When I press a button with the same stage I save previously I change the scene to another FXML document

    stage.setFullScreen(true);

    currentStage = stage;
  }

 @FXML
  private void handleButtonAction(ActionEvent event) throws IOException {
    Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));
    JavaFXApplication12.currentStage.setScene(new Scene(root));
  }

推荐答案

我不知道真正的原因，但这里有2个快速解决方法。

在 handleButtonAction 方法：

1）不要创建新场景只需替换其内容

I have no idea about the real cause but here are 2 quick workarounds.
In the handleButtonAction method:
1) Don't create new scene just replace its content

  @FXML
  private void handleButtonAction(ActionEvent event) throws IOException {
    Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));
    JavaFXApplication12.currentStage.getScene().setRoot(root);
  }

2）如果你真的想创造新的场景然后切换全屏

2) If you really nead to create new scene then toggle fullscreen

  @FXML
  private void handleButtonAction(ActionEvent event) throws IOException {
    Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));
    JavaFXApplication12.currentStage.setScene(new Scene(root));
    Platform.runLater(new Runnable() {
        @Override
        public void run() {
           JavaFXApplication12.currentStage.setFullScreen(false);
           JavaFXApplication12.currentStage.setFullScreen(true);
       }
    });
  }
