Change Font type and size for the whole JFrame?
提问by Ankit
I am working on Java GUI project. I have several components on the swing-based GUI. I want to change the font settings for all the components, rather than changing font for each component one by one.
我正在研究 Java GUI 项目。我在基于 Swing 的 GUI 上有几个组件。我想更改所有组件的字体设置，而不是一个一个更改每个组件的字体。
Is there a way to change the font type and size of all the components on a JPanel on a JFrame.
有没有办法更改 JFrame 上 JPanel 上所有组件的字体类型和大小。

This is how my code looks:
这是我的代码的样子：
public class Test extends JFrame{
public Test(){
//all components are initialized here. (some buttons and text fields) and added to this
this.setVisible(true);
}
public static void main(String []args){
new Test();
}
}

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);
}
}
// ...
try
{
setUIFont(new javax.swing.plaf.FontUIResource("Tahoma",Font.PLAIN,12));
}
catch(Exception e){}
PS: I just copied this from old project of mine, and I am not sure from where I got it.

You can set this Fontinto UIManager, but for every type of JComponentsbecase each of them have got own syntax in UIManager Defaultsand here
您可以将其设置Font为UIManager，但对于每种类型，JComponents因为它们中的每一种在UIManager Defaults和此处都有自己的语法
