设置自定义字体

我试图设置一个自定义字体(bilboregular.ttf)2 jLabels在我的程序字体不是被成功加载。

这里是主要的方法调用:

//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 } } 

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; } } 

首先获得一个FontURL 。 然后做这样的事情。

下载免费字体 “Airacobra Condensed” 字体 。

注册的字体

 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)); } } 

好吧,那很有趣,但是这个字体实际上是什么样的?

显示字体

 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); } } 
  • 不要单独为JLabel重复加载新的Font

手段

 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; } } 
  • 创build一个Font作为Local variable并只改变jLabel3.setFont(myFont) ,或注册一个新的字体( 参见@StanislavLs评论的链接 )

例如

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