使用AwesomeFont中的自定义字体和Java Swing中的unicode字符向JButton添加图标？

I have a JButton and I want to add an icon to it. I would like to use the font based icons from FontAwesome which provides a TrueType font file. The icon I am trying to add is the play button icon. The play button icon in the css file for FontAwesome is \f04b which I beleive translates to \uf04b in Java.

我有一个JButton，我想添加一个图标。我想使用FontAwesome中提供TrueType字体文件的基于字体的图标。我想添加的图标是播放按钮图标。 FontAwesome的css文件中的播放按钮图标是\ f04b，我在Java中将其转换为\ uf04b。

This is how I am loading the font in the constructor of by IconButton base class.

这就是我在IconButton基类的构造函数中加载字体的方法。

public class IconButton extends JButton {
  public IconButton() {
    try {
      InputStream in = this.getClass().getResourceAsStream("/fontawesome-webfont.ttf");
      Font ttfBase = Font.createFont(Font.TRUETYPE_FONT, in);
      Font ttfReal = ttfBase.deriveFont(Font.BOLD, 24);
      setFont(ttfReal);
    } catch (FontFormatException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
  }
}

In the implementing class StartButton this is how I am setting the text.

在实现类StartButton中，这是我设置文本的方式。

public class StartButton extends IconButton {
  public StartButton() {
    setText(String.valueOf('\u0f4b'));
    setForeground(Color.BLACK);
  }
}

This is what I get. Nothing.

这就是我得到的。没有。

Any help is much appreciated.

任何帮助深表感谢。

#1

I think I solved this actually. The correct character is \uf04b not \u0f4b. Whoops! :)

我想我实际上解决了这个问题。正确的字符是\ uf04b而不是\ u0f4b。哎呦！ :)

This is working for me now.

这对我现在很有用。

Try jIconFont (Swing or JavaFX) at http://jiconfont.github.io/

在http://jiconfont.github.io/上试试jIconFont（Swing或JavaFX）

Example:

例：

Icon icon = IconFontSwing.buildIcon(FontAwesome.FLOPPY_O, 15);

JButton button = new JButton(icon);
