• JCheckBoxのチェックアイコンはJCheckBox#setIcon(Icon)メソッドで変更可能
• JCheckBoxMenuItemはチェックアイコンとは別のアイコンが設定されているため、setIcon(Icon)メソッドではなくUIManager.put("CheckBoxMenuItem.checkIcon", icon)を使用する必要がある
• NimbusLookAndFeelなどではUIManager.put("CheckBoxMenuItem.checkIcon", icon)は無効なのでUIDefaultsを使用する必要がある

• Nimbusなどの場合 -- terai 2009-11-20 (金) 13:54:08
