* Source Code Examples [#sourcecode]
#code(link){{
UIManager.put("CheckBox.disabledText", Color.RED);
JCheckBox cbx1 = new JCheckBox("default", true);
JCheckBox cbx2 = new JCheckBox("<html>html <span style='color:red'>tag");
}}

* Explanation [#explanation]
- `JCheckBox`
-- `UIManager.put("CheckBox.disabledText", Color.RED)`
--- `MetalLookAndFeel`でのみ有効
- `JCheckBox` + `html`
-- `JDK 1.7.0`で以下の動作は修正されて、無効化で`HTML`文字列もグレーになる
--- [https://bugs.openjdk.org/browse/JDK-4783068 Bug ID: 4783068 Components with HTML text should gray out the text when disabled]
-- %%`<html>`タグを使った場合、文字色は常に不変で`isEnabled()`の状態に依存しない([https://bugs.openjdk.org/browse/JDK-4740519 Bug ID: 4740519 HTML JLabel not greyed out on setEnabled(false)])を利用%%

--- [[Htmlを使ったJLabelとJEditorPaneの無効化>Swing/DisabledHtmlLabel]]
- `JComboBox`
-- `UIManager.put("ComboBox.disabledForeground", Color.GREEN);`
- `JComboBox` + `html`
-- レンダラーで文字色を変更
- `JComboBox`(`Editable`)
-- `EditorComponent`を取得して、`editor.setDisabledTextColor(Color.PINK);`を設定
- `JLabel`
-- `UIManager.put("Label.disabledForeground", Color.ORANGE);`
- `JButton`
-- `UIManager.put("Button.disabledText", Color.YELLOW)`
--- `MetalLookAndFeel`でのみ反映
