Setting the Default Font of Swing Program

Asked 15/9, 2011 at 17:13 Answered 2/5, 2018 at 2:20

I was wondering how to set the default font for my entire Java swing program. From my research it appears it can be done with UIManager, something to do with LookAndFeel, but I can't find specifically how to do it, and the UIManager appears pretty complicated.

try:

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);
      }
    }

Call by ...

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

For some reason, this is only changing the font on the text of the tabs on my JTabbedPane. – Flowage 15/9, 2011 at 22:43

I had it working using UIManager.getLookAndFeelDefaults() instead of UIManager.getDefaults() and using the returned reference instead of UIManager.put() (see my answer below). It works only when overriding the default L&F though (Nimbus in my case)... – Gunning 21/8, 2014 at 16:26

UIManager.put("Button.font", /* font of your liking */);
UIManager.put("ToggleButton.font", /* font of your liking */);
UIManager.put("RadioButton.font", /* font of your liking */);
UIManager.put("CheckBox.font", /* font of your liking */);
UIManager.put("ColorChooser.font", /* font of your liking */);

waw... is that working by adding New Font object to the /* font of your liking */ portion? Bcoz, it seems that Once the JFRame created and running... There's no effect I obtained. Is there anything I Forgotten @Amir Raminfar? – Disadvantageous 22/12, 2011 at 10:20

Source's source: BasicLookAndFeel.java – Donetsk 16/8, 2013 at 15:2

Additional information: Some components have multiple keys to set the font for a distinct part of the component. For example JOptionPane: To set the default fonts for JOptionPane you should use: UIManager.put("OptionPane.messageFont", /*font*/); and UIManager.put("OptionPane.buttonFont", /*font*/); – Engvall 14/11, 2014 at 17:52

@Disadvantageous it works when you refresh the content tree SwingUtilities.updateComponentTreeUI(this); – Wrongdoer 23/2, 2017 at 10:22

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

This will not only set Tahoma on your complete UI but also turn on anti-aliasing which makes any font much more beautiful immediately.

Blenny answered 15/9, 2011 at 18:15 Comment(2)

works great. And to set a font which has spaces in its name you can quote. Also specify the font size by adding a "-": -Dswing.plaf.metal.controlFont="Droid Sans-15" (size 15) – Slipper 31/1, 2013 at 20:30

Doesn't work at all for me. Throws unrecognized option errors. – Acriflavine 6/12, 2013 at 19:48

I think this is better, calling it for the current laf instead of the whole UIManager put this

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

Somewhere in the main before instantiating your JFrame object. It worked perfectly for me. Remember this is the default font, for the components that have no specified font.

works fine for a netbeans swing app made with palette, drag and drop. – Boredom 5/9, 2014 at 10:0

Inspired by Romain Hippeau, use this code if you want to set just the font size.

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);
    }
}

A more accurate way will be UIManager.put(key, new javax.swing.plaf.FontUIResource(fr.deriveFont(fr.getSize2D() * 2.0f))); – Radiothermy 12/10, 2016 at 16:7

Be aware that the way to set the default font depends on the Look And Feel you're using. The solution described by Romain Hippeau works fine with a lot of LAF but not with Nimbus. The one posted by sherif works fine with Nimbus, but not with others (Metal, for instance).

Combining both could work on most of LAF, but none of these solutions works with GTK+ LAF.

I think (but I'm not sure), there's no cross-platform solution.

As a completion of @Amir answer, this is the complete list of keys

I use this function

private void setFont(FontUIResource myFont) {
    UIManager.put("CheckBoxMenuItem.acceleratorFont", myFont);
    UIManager.put("Button.font", myFont);
    UIManager.put("ToggleButton.font", myFont);
    UIManager.put("RadioButton.font", myFont);
    UIManager.put("CheckBox.font", myFont);
    UIManager.put("ColorChooser.font", myFont);
    UIManager.put("ComboBox.font", myFont);
    UIManager.put("Label.font", myFont);
    UIManager.put("List.font", myFont);
    UIManager.put("MenuBar.font", myFont);
    UIManager.put("Menu.acceleratorFont", myFont);
    UIManager.put("RadioButtonMenuItem.acceleratorFont", myFont);
    UIManager.put("MenuItem.acceleratorFont", myFont);
    UIManager.put("MenuItem.font", myFont);
    UIManager.put("RadioButtonMenuItem.font", myFont);
    UIManager.put("CheckBoxMenuItem.font", myFont);
    UIManager.put("OptionPane.buttonFont", myFont);
    UIManager.put("OptionPane.messageFont", myFont);
    UIManager.put("Menu.font", myFont);
    UIManager.put("PopupMenu.font", myFont);
    UIManager.put("OptionPane.font", myFont);
    UIManager.put("Panel.font", myFont);
    UIManager.put("ProgressBar.font", myFont);
    UIManager.put("ScrollPane.font", myFont);
    UIManager.put("Viewport.font", myFont);
    UIManager.put("TabbedPane.font", myFont);
    UIManager.put("Slider.font", myFont);
    UIManager.put("Table.font", myFont);
    UIManager.put("TableHeader.font", myFont);
    UIManager.put("TextField.font", myFont);
    UIManager.put("Spinner.font", myFont);
    UIManager.put("PasswordField.font", myFont);
    UIManager.put("TextArea.font", myFont);
    UIManager.put("TextPane.font", myFont);
    UIManager.put("EditorPane.font", myFont);
    UIManager.put("TabbedPane.smallFont", myFont);
    UIManager.put("TitledBorder.font", myFont);
    UIManager.put("ToolBar.font", myFont);
    UIManager.put("ToolTip.font", myFont);
    UIManager.put("Tree.font", myFont);
    UIManager.put("FormattedTextField.font", myFont);
    UIManager.put("IconButton.font", myFont);
    UIManager.put("InternalFrame.optionDialogTitleFont", myFont);
    UIManager.put("InternalFrame.paletteTitleFont", myFont);
    UIManager.put("InternalFrame.titleFont", myFont);
}

and i call it in main before invoking the ui

setFont(new FontUIResource(new Font("Cabin", Font.PLAIN, 14)));

Haggar answered 2/5, 2018 at 2:20 Comment(1)

note calling it BEFORE invoking the ui is necessary else only few places the font effect takes place. – Cerallua 24/9, 2020 at 8:15

The correct answer is the one given by Amir Raminfar but you have to encapsulate the font as a FontUIResource.

For example:

UIManager.put("Button.font", new FontUIResource(new Font ("Helvetica", Font.BOLD, 16)));

Costumier answered 23/4, 2016 at 11:44 Comment(1)

Sorry I think this code is better : UIManager.put("Button.font", new FontUIResource("Helvetica", Font.BOLD, 16)); – Costumier 23/4, 2016 at 16:57

I'm using Nimbus L&F.

Using code from @Romain Hippeau, I had to use UIManager.getLookAndFeelDefaults() instead of UIManager.getDefaults() and use the returned reference to put modified values:

    int szIncr = 5; // Value to increase the size by
    UIDefaults uidef = UIManager.getLookAndFeelDefaults();
    for (Entry<Object,Object> e : uidef.entrySet()) {
        Object val = e.getValue();
        if (val != null && val instanceof FontUIResource) {
            FontUIResource fui = (FontUIResource)val;
            uidef.put(e.getKey(), new FontUIResource(fui.getName(), fui.getStyle(), fui.getSize()+szIncr));
        }
    }

For some reason, it does not seem to work with the default L&F... (based on the limited tests I performed)

To solve this problem, I just implement AWTEventListener and listen for COMPONENT_ADDED of ContainerEvent.

All story description at: http://wiki.idempiere.org/en/Swing_Miss_Support_Some_Language

All code at: https://bitbucket.org/hieplq/unicentapos/src/9b22875ab65e26ff46fd9ae62d556b7f64621afa/src-extend/vn/hsv/uitil/font/FontGlyphsUtil.java?at=tip

Implement AWTEventListener

public void eventDispatched(AWTEvent event) {
    if (!isMissSupportGlyph || !(event instanceof ComponentEvent) || !(event instanceof ContainerEvent))
        return;

    if (event instanceof ContainerEvent){
        ContainerEvent containerEvent = (ContainerEvent)event;
        if (containerEvent.getID() == ContainerEvent.COMPONENT_ADDED){
            updateChildControlFont(containerEvent.getChild());
        }
    }
}

Add registry listener (the best place to run this is when starting the program)

Toolkit.getDefaultToolkit().addAWTEventListener(this, AWTEvent.COMPONENT_EVENT_MASK | AWTEvent.CONTAINER_EVENT_MASK);

Mons answered 13/6, 2015 at 13:32 Comment(0)

I used the Synth look and feel XML file and defined the fonts there. Easy, flexible and continent.
You need to create a class with a createFont like:

public class CustomFontResource {
public static FontUIResource createFont(String path, final int size) throws IOException, FontFormatException {
    Font font = Font.createFont(Font.TRUETYPE_FONT, new FileInputStream(path));
    return new FontUIResource(font.deriveFont(Font.PLAIN, size));
}

And in your synth xml define the font like:

    <object id="Basic_Regular" class="<your CustomFontResource class>"
        method="createFont">
    <string>path_to_your_font</string>
    <int>font_size</int>
</object>

then you may use it as a reference wherever you want in the xml.

None of these solutions work fine for me, I built my own (stupid) one but it works:

private void changeFontRecursive(Container root, Font font) {
    for (Component c : root.getComponents()) {
        c.setFont(font);
        if (c instanceof Container) {
            changeFontRecursive((Container) c, font);
        }
    }
}
