我试图在我的JFrame中使用特殊字体,但我遇到了问题。我有一个像这样定义的JLabel:
private JLabel lab = new JLabel("Text");
我有一个名为CUSTOMFONT-MEDIUM.TTF(TrueType字体)的文件,但在写完以下内容之后:
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,一切正常,除了" lab"没有显示,所以没有文字。我想这是因为我从未指定字体大小应该是什么,但是我做的任何尝试都失败了。有人可以帮助我吗?

@sasankad大多是正确的(+1)。
创建字体后,其默认大小为1
Font font = Font.createFont(Font.TRUETYPE_FONT, getClass().getResourceAsStream("/CUSTOMFONT-MEDIUM.TTF"));
然后,您需要派生所需的字体大小和样式。
Font biggerFont = font.deriveFont(Font.BOLD, 48f);
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.Font;
import java.awt.FontFormatException;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.GridBagLayout;
import java.io.File;
import java.io.IOException;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class TestCustomFont {
public static void main(String[] args) {
new TestCustomFont();
}
public TestCustomFont() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
ex.printStackTrace();
}
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
public TestPane() {
setLayout(new GridBagLayout());
try {
Font font = Font.createFont(Font.TRUETYPE_FONT, getClass().getResourceAsStream("/Royal Chicken.ttf"));
JLabel happy = new JLabel("Happy little Miss Chicken");
happy.setFont(font.deriveFont(Font.BOLD, 48f));
add(happy);
} catch (FontFormatException | IOException ex) {
ex.printStackTrace();
}
}
}
}

您创建的字体必须首先在GraphicsEnvironment
中注册才能被所有人访问并获得字体大小:
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);
