设置Swing程序的默认字体

Question

我想知道如何为我的整个Java swing程序设置默认字体.根据我的研究,它似乎可以完成,与UIManager某些事情有关LookAndFeel,但我找不到具体的方法,UIManager看起来很复杂.

Answer 1

尝试:

public static void setUIFont (javax.swing.plaf.FontUIResource f){
    java.util.Enumeration keys = UIManager.getDefaults().keys();
    while (keys.hasMoreElements()) {
      Object key = keys.nextElement();
      Object value = UIManager.get (key);
      if (value instanceof javax.swing.plaf.FontUIResource)
        UIManager.put (key, f);
      }
    } 

打电话给......

setUIFont (new javax.swing.plaf.FontUIResource("Serif",Font.ITALIC,12));

Answer 3

java -Dswing.aatext=true -Dswing.plaf.metal.controlFont=Tahoma -Dswing.plaf.metal.userFont=Tahoma …

这不仅可以在您的完整UI上设置Tahoma,还可以启用抗锯齿功能,使任何字体立即变得更加美观.

Answer 4

我认为这更好,称之为当前的laf,而不是整个UIManager把它

UIManager.getLookAndFeelDefaults()
        .put("defaultFont", new Font("Arial", Font.BOLD, 14));

在实例化JFrame对象之前的主要位置.它对我来说很完美.请记住,对于没有指定字体的组件,这是默认字体.

受 Romain Hippeau 的启发，如果您只想设置字体大小，请使用此代码。

for (Map.Entry<Object, Object> entry : javax.swing.UIManager.getDefaults().entrySet()) {
    Object key = entry.getKey();
    Object value = javax.swing.UIManager.get(key);
    if (value != null && value instanceof javax.swing.plaf.FontUIResource) {
        javax.swing.plaf.FontUIResource fr=(javax.swing.plaf.FontUIResource)value;
        javax.swing.plaf.FontUIResource f = new javax.swing.plaf.FontUIResource(fr.getFamily(), fr.getStyle(), FONT_SIZE);
        javax.swing.UIManager.put(key, f);
    }
}

Answer 6

请注意，设置默认字体的方式取决于您使用的外观。Romain Hippeau 描述的解决方案适用于很多 LAF，但不适用于 Nimbus。sherif 发布的那篇文章在 Nimbus 上工作得很好，但对其他人（例如 Metal）则不行。

将两者结合可以适用于大多数 LAF，但这些解决方案都不适用于 GTK+ LAF。

我认为（但我不确定），没有跨平台的解决方案。
