使用JLabel的自定义字体 [英] Using a custom font for a JLabel

问题描述

我试图在我的JFrame中使用特殊的字体，但是我遇到了问题。我有一个像这样定义的JLabel：

I'm trying to use a special font in my JFrame, but I'm running into problems. I have a JLabel defined like this:

private JLabel lab = new JLabel("Text");

我有一个名为CUSTOMFONT-MEDIUM.TTF（TrueType字体）的文件，

and I have a file called CUSTOMFONT-MEDIUM.TTF (TrueType font) but after writing the following:

    try {
    lab.setFont(Font.createFont(Font.TRUETYPE_FONT, getClass().getResource("/CUSTOMFONT-MEDIUM.TTF").openStream()));
    } catch(IOException ex){
    //exception handled here I suppose  
    } catch(FontFormatException ex2) {
    //same here
    }

代码编译和一切工作正确，除了实验室没有显示，所以没有文字。我想这是因为我从来没有指定字体大小应该是什么，但是我所做的任何尝试都失败了。有人可以帮助我吗？

the code compiles and the everything works right except that "lab" is not displayed so there is no text. I suppose it is because I never specified what the font size should be, but any attempt I have made to do that fails. Can someone help me out here?

推荐答案

您创建的字体必须首先在 GraphicsEnvironment 可被所有人访问，并获得字体的大小：

The Font you created has to be registered first in the GraphicsEnvironment to be accessible to all and derive the size of the font:

Font font = Font.createFont(Font.TRUETYPE_FONT, getClass().getResource("/CUSTOMFONT-MEDIUM.TTF").openStream());   

GraphicsEnvironment genv = GraphicsEnvironment.getLocalGraphicsEnvironment();
genv.registerFont(font);
// makesure to derive the size
font = font.deriveFont(12f);
