java 设置自定义字体

Setting custom font

提问by mangusbrother

I'm trying to set a custom font (bilboregular.ttf) to 2 jLabels in my program The fonts aren't being loaded successfully though.

我正在尝试在我的程序中将自定义字体 (bilboregular.ttf) 设置为 2 个 jLabel 但是字体没有成功加载。

Here is the main method calls:

下面是主要的方法调用：

//this should work if the build is in a jar file, otherwise it'll try to load it directly from the file path (i'm running in netbeans)
if (!setFonts("resources/bilboregular.ttf")) {
        System.out.println("=================FAILED FIRST OPTION"); // <<<<<<<< This is being displayed
if(!setFonts(System.getProperty("user.dir")+"/src/resources/bilboregular.ttf")){
            System.out.println("=================FAILED SECOND OPTION"); // <<< This is not being displayed
        }
    }

Here is the other method:

这是另一种方法：

public boolean setFonts(String s) {
    try {
jLabel3.setFont(java.awt.Font.createFont(java.awt.Font.TRUETYPE_FONT, new java.io.File(s)));
jLabel4.setFont(java.awt.Font.createFont(java.awt.Font.TRUETYPE_FONT, new java.io.File(s)));
        return true;
    } catch (Exception ex) {
        return false;
    }
}

Firstly gain an URLto the Font. Then do something like this.

首先抢占URL的Font。然后做这样的事情。

'Airacobra Condensed' font available from Download Free Fonts.

'Airacobra Condensed' 字体可从下载免费字体 获得。

import java.awt.*;
import javax.swing.*;
import java.net.URL;

class LoadFont {
    public static void main(String[] args) throws Exception {
        // This font is < 35Kb.
        URL fontUrl = new URL("http://www.webpagepublicity.com/" +
            "free-fonts/a/Airacobra%20Condensed.ttf");
        Font font = Font.createFont(Font.TRUETYPE_FONT, fontUrl.openStream());
        GraphicsEnvironment ge = 
            GraphicsEnvironment.getLocalGraphicsEnvironment();
        ge.registerFont(font);
        JList fonts = new JList( ge.getAvailableFontFamilyNames() );
        JOptionPane.showMessageDialog(null, new JScrollPane(fonts));
    }
}

OK, that was fun, but what does this font actually look like?

好吧，这很有趣，但是这种字体实际上是什么样子的？

import java.awt.*;
import javax.swing.*;
import java.net.URL;

class DisplayFont {
    public static void main(String[] args) throws Exception {
        URL fontUrl = new URL("http://www.webpagepublicity.com/" +
            "free-fonts/a/Airacobra%20Condensed.ttf");
        Font font = Font.createFont(Font.TRUETYPE_FONT, fontUrl.openStream());
        font = font.deriveFont(Font.PLAIN,20);
        GraphicsEnvironment ge =
            GraphicsEnvironment.getLocalGraphicsEnvironment();
        ge.registerFont(font);

        JLabel l = new JLabel(
            "The quick brown fox jumped over the lazy dog. 0123456789");
        l.setFont(font);
        JOptionPane.showMessageDialog(null, l);
    }
}

• don't load a new Fontrepeatly, for each of JLabelseparatelly

• 不要Font为每个JLabel单独加载一个新的

means

方法

public boolean setFonts(String s) {
    try {
jLabel3.setFont(java.awt.Font.createFont(java.awt.Font.TRUETYPE_FONT, new java.io.File(s)));
jLabel4.setFont(java.awt.Font.createFont(java.awt.Font.TRUETYPE_FONT, new java.io.File(s)));
        return true;
    } catch (Exception ex) {
        return false;
    }
}

• create a Font(s) as Local variable(s) and to change only jLabel3.setFont(myFont), or register a new Font (see link from @StanislavLs comment)

• 创建Font(s) as Local variable(s) and to change only jLabel3.setFont(myFont)，或注册新字体（请参阅@StanislavLs 评论中的链接）

for example

例如

InputStream myFont = OptionsValues.class.getResourceAsStream(
     "resources/bilboregular.ttf");
