Label에 대한 Font를 나눔고딕(NanumGothic)으로 설정.

UIManager.put("Label.font", new Font("NanumGothic", Font.PLAIN, 12));

다른 Component의 Font를 설정하고 싶을때에는 해당 Key 값을 변경하면 되겠다.

Swing Component의 Font Key 값은 아래와 같다.

Swing Platform FontUIResources.

Key : OptionPane.buttonFont

Key : List.font

Key : TableHeader.font

Key : Panel.font

Key : TextArea.font

Key : ToggleButton.font

Key : ComboBox.font

Key : ScrollPane.font

Key : Spinner.font

Key : RadioButtonMenuItem.font

Key : Slider.font

Key : EditorPane.font

Key : OptionPane.font

Key : ToolBar.font

Key : Tree.font

Key : CheckBoxMenuItem.font

Key : FileChooser.listFont

Key : Table.font

Key : MenuBar.font

Key : PopupMenu.font

Key : Label.font

Key : MenuItem.font

Key : MenuItem.acceleratorFont

Key : TextField.font

Key : TextPane.font

Key : CheckBox.font

Key : ProgressBar.font

Key : FormattedTextField.font

Key : CheckBoxMenuItem.acceleratorFont

Key : Menu.acceleratorFont

Key : ColorChooser.font

Key : Menu.font

Key : PasswordField.font

Key : InternalFrame.titleFont

Key : OptionPane.messageFont

Key : RadioButtonMenuItem.acceleratorFont

Key : Viewport.font

Key : TabbedPane.font

Key : RadioButton.font

Key : ToolTip.font

Key : Button.font

해당 Swing Component 전체 Font를 나눔고딕(NanumGothic)으로 설정.

setUIFont(new javax.swing.plaf.FontUIResource("NanumGothic", java.awt.Font.PLAIN, 12));
	
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);
        }
    }
}

Swing Application을 실행하기 전에 적용하고 실행하면 되겠다.

Swing Look And Feel JRE(Java Runtime Environment) 1.6 이상 지원이 된다.

기본적으로 JRE 1.6 이상 지원이 되는 Look And Feel에는

코드를 실행해보면 결과와 같이 setSize 같은경우 해당 Frame을 다시 그리고, setPrefereedSize 같은 경우에는 그리지 않는다.
