JavaFX没有找到所有的系统字体 [英] JavaFX not finding all system fonts

问题描述

我注意到，我使用的JavaFX组件不像Swing的对应组件，不能正确地渲染一些系统字体。这里是完整的例子，展示了这个问题。

  public class JavaFXApplication1 extends Application {
 
 @Override 
 public void start（Stage primaryStage）{
 // Swing button 
 SwingNode node = new SwingNode（）; 
 SwingUtilities.invokeLater（（） - > {
 JButton swingButton = new JButton（Comic Sans MS）; 
 swingButton.setFont（new java.awt.Font（Comic Sans MS ，java.awt.Font.PLAIN，20））; 
 node.setContent（swingButton）; 
}）; 
 
 // JavaFX按钮
 Button fxButton = new Button（Comic Sans MS）; 
 fxButton.setFont（Font.font（Comic Sans MS，20））; 
 
 HBox hbox = new HBox（）; 
 hbox.getChildren（）。addAll（node，fxButton）; 
 
场景场景=新场景（hbox，300，250）; 
 primaryStage.setTitle（Font test）; 
 primaryStage.setScene（scene）; 
 primaryStage.show（）; 
 
 
 public static void main（String [] args）{
 launch（args）; 
 
 
 
 
 $ b $如果你的系统中有Comic Sans MS字体，你应该看到下面的结果。只有Swing组件看起来不错：
 
 
 
  
 
 
 
显然FX图形系统在启动时不加载所有系统字体。最明显的解决方案是手动加载丢失的文件，如下所示： 
 
 
  Font.loadFont（new FileInputStream（System.getenv WINDIR）+\\fonts\\+comic.ttf），20）; 
  
现在一切正常，但这个解决方案不是跨平台的，我真的期望它就像在Swing中那样开箱即用。我错过了什么吗？如果没有，那么为什么只有一部分系统字体被加载到JavaFX环境中？
 
 
我在Windows 10上运行它。
 
我找到了另外一件事：我创建了下面的代码： 
 
 
  > String fonts [] = GraphicsEnvironment.getLocalGraphicsEnvironment（）。getAvailab leFontFamilyNames（）; for（String font：fonts）{System.out.printf（This is font％s％n，font）; 
  
返回例如：这是字体Something Strange（它是我下载和安装的一种字体）其可用。但是，当我把它放到这个代码：
 
 
 < GridPane fx：controller =sample.Controller
 xmlns ：fx =http://javafx.com/fxmlalign =centerhgap =10vgap =10
 style = -  fx-font-family：奇怪的东西> 
  
文字完全不会改变。也许这有助于你/我们的问题。  
I've noticed that the JavaFX components I use, unlike their Swing counterparts, are not rendering some system fonts properly. Here's the complete example that presents the issue.
public class JavaFXApplication1 extends Application {

    @Override
    public void start(Stage primaryStage) {
        // Swing button
        SwingNode node = new SwingNode();
        SwingUtilities.invokeLater(() -> {
            JButton swingButton = new JButton("Comic Sans MS");
            swingButton.setFont(new java.awt.Font("Comic Sans MS", java.awt.Font.PLAIN, 20));
            node.setContent(swingButton);
        });

        // JavaFX button
        Button fxButton = new Button("Comic Sans MS");
        fxButton.setFont(Font.font("Comic Sans MS", 20));

        HBox hbox = new HBox();
        hbox.getChildren().addAll(node, fxButton);

        Scene scene = new Scene(hbox, 300, 250);
        primaryStage.setTitle("Font test");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
If you have the Comic Sans MS font in your system, you should see the following result. Only the Swing component looks fine:



Apparently the FX graphics system does not load all system fonts on startup. The most obvious solution is to load the missing ones manually, like that:
Font.loadFont(new FileInputStream(System.getenv("WINDIR")+"\\fonts\\"+"comic.ttf"), 20);
Now everything renders properly, but this solution isn't cross platform and I'd really expect it to work out-of-the-box just like it was in Swing. Am I missing something? If not, then why only a subset of system fonts is loaded into the JavaFX environment?

I'm running it on Windows 10.
解决方案
I figured out another thing: I created following code
String fonts[] = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailab‌​leFontFamilyNames(); for(String font: fonts) { System.out.printf("This is font %s %n", font);
This returns for example: This is font Something Strange (its a font which i downloaded and installed) so its available. But when I put it into this code:
<GridPane fx:controller="sample.Controller"
      xmlns:fx="http://javafx.com/fxml" alignment="center" hgap="10" vgap="10"
      style="-fx-font-family: Something Strange">
The text does not change at all. Maybe this contribute to your / our problem.
