How to change fonts of all components

Question

How can I change the font of all components that are displayed in my java application?

I tried it using the UIManager

UIManager.put("TextField.font",  new java.awt.Font("Arial Unicode MS", java.awt.Font.PLAIN, 11));
UIManager.put("Label.font",  new java.awt.Font("Arial Unicode MS", java.awt.Font.PLAIN, 11));
UIManager.put("ComboBox.font",  new java.awt.Font("Arial Unicode MS", java.awt.Font.PLAIN, 11))

Oddly enough this changed the font of the textfield but did not work for JLabels or JComboBoxes

Then I tried to set the font by looping over all keys the UIManager knows:

public static void setUIFont(FontUIResource f) {
    Enumeration keys = UIManager.getDefaults().keys();
    while (keys.hasMoreElements()) {
        Object key = keys.nextElement();
        Object value = UIManager.get(key);
        if (value instanceof FontUIResource) {
            FontUIResource orig = (FontUIResource) value;
            Font font = new Font(f.getFontName(), orig.getStyle(), f.getSize());
            FontUIResource fontUIResource = new FontUIResource(font);
            UIManager.put(key, fontUIResource);
            UIManager.getDefaults().put(key, fontUIResource);
            UIManager.getLookAndFeel().getDefaults().put(key, fontUIResource);
        }
    }
}

This code did not work at all.

I must say that I use Synthetica as LookAndFeel... so I don't know how that interferes with my manuell settings via UIManager.

[Moreover it enables you to modify existing Themes and to create your own look and feel only by editing a XML-based configuration file - you don't have to write complex Java-GUI-Code.](http://www.javasoft.de/synthetica/) — mKorbel, May 27 '15 at 12:19

I think you can update this answer from Roman as follows:

public static void setUIFont (java.awt.Font f){
    java.util.Enumeration keys = UIManager.getDefaults().keys();
    while (keys.hasMoreElements()) {
      Object key = keys.nextElement();
      Object value = UIManager.get (key);
      if (value != null && value instanceof java.awt.Font)
        UIManager.put (key, f);
      }
}

Then use it with your Font like this:

setUIFont (new java.awt.Font("Arial Unicode MS", java.awt.Font.PLAIN, 11));

*"`new java.awt.Font("Arial Unicode MS"..`"* For greater cross-platform support, use logical fonts (e.g. `Font.SANS_SERIF` as opposed to `"Arial Unicode MS"`). – Andrew Thompson May 27 '15 at 10:34
agree... but I just used `Font` in the original question.... – Jordi Castilla May 27 '15 at 10:35
It didn't work. I debugged the code and the values are written for each component, but the UI is still the same. Is it possible that Synthetica ignores those manuell settings? – mareicha May 27 '15 at 11:25
This is a copy-paste answer from [here](http://stackoverflow.com/a/7434935/1803551), you just changed the name and number a bit. – user1803551 May 28 '15 at 07:37
@user1803551 actually I use it in one of my apps, and YES, I guess I took it from there cause my upvote is still there... where is the problem? – Jordi Castilla May 28 '15 at 07:46

My bad, agree and [corrected](http://meta.stackexchange.com/a/160078/278325). @user1803551 – Jordi Castilla May 28 '15 at 08:08
Alright. Now why not just vote to close as duplicate? – user1803551 May 28 '15 at 08:19
Well, it was closed as a duplicate anyway. – user1803551 May 29 '15 at 06:00
Doesn't work for me. – SebastianR Oct 22 '21 at 16:23

You can create your own components like:

public class MyJButton extends JButton {

    public MyJButton(){
        setFont(FontClass.getBasicFont());
    }

}

public class MyJTextArea extends JTextArea {

    public MyJTextArea (){
        setFont(FontClass.getBasicFont());
    }

}
.
.
.

And then create this class which holds all your fonts properties like:

public class FontClass(){

    private static final String BASIC_FONT_FACE = "Arial";

    private static final String BASIC_FONT_SIZE = 12;

    public static Font getBasicFont(){
        return new Font(BASIC_FONT_FACE, Font.PLAIN, BASIC_FONT_SIZE);
    }

}

I suppose that this is the primitive way, but it can be good if you want to save these values in your DB
