Need way to have a different background color for focused text components

[Chrriis]

Hi all!

GitHub and Firefox, among others, have text components with a gray background that becomes white when focused.
Example:

I am trying to achieve a similar effect with FlatLaf but I don't see any properties to tweak the behavior on focus. Am I missing something? I tried these:

• TextField.focusedBackground
• PasswordField.focusedBackground
• TextArea.focusedBackground
• ComboBox.editableFocusedBackground

Here is the test code:

public static void main(String[] args) throws Exception {
	UIManager.setLookAndFeel(new FlatLightLaf());
	UIManager.getDefaults().put("Panel.background", Color.WHITE);
	UIManager.getDefaults().put("TextField.background", new Color(0xf0f0f0));
	UIManager.getDefaults().put("TextField.focusedBackground", Color.WHITE);
	UIManager.getDefaults().put("PasswordField.background", new Color(0xf0f0f0));
	UIManager.getDefaults().put("PasswordField.focusedBackground", Color.WHITE);
	UIManager.getDefaults().put("TextArea.background", new Color(0xf0f0f0));
	UIManager.getDefaults().put("TextArea.focusedBackground", Color.WHITE);
	UIManager.getDefaults().put("ComboBox.editableBackground", new Color(0xf0f0f0));
	UIManager.getDefaults().put("ComboBox.editableFocusedBackground", Color.WHITE);
	JFrame frame = new JFrame();
	frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	JPanel centerPane = new JPanel(new GridBagLayout());
	centerPane.setBorder(BorderFactory.createEmptyBorder(20, 40, 20, 40));
	int y = 0;
	centerPane.add(new JTextField("Sample text field", 14), new GridBagConstraints(0, y++, 1, 1, 0, 0, GridBagConstraints.WEST, GridBagConstraints.HORIZONTAL, new Insets(0, 0, 0, 0), 0, 0));
	centerPane.add(new JPasswordField("Password field", 14), new GridBagConstraints(0, y++, 1, 1, 0, 0, GridBagConstraints.WEST, GridBagConstraints.HORIZONTAL, new Insets(5, 0, 0, 0), 0, 0));
	centerPane.add(new JScrollPane(new JTextArea("Sample text area", 5, 14)), new GridBagConstraints(0, y++, 1, 1, 0, 0, GridBagConstraints.WEST, GridBagConstraints.HORIZONTAL, new Insets(5, 0, 0, 0), 0, 0));
	JComboBox<String> combo = new JComboBox<>(new String[] {"Item 1", "Item 2", "Item 3"});
	combo.setEditable(true);
	centerPane.add(combo, new GridBagConstraints(0, y++, 1, 1, 0, 0, GridBagConstraints.WEST, GridBagConstraints.HORIZONTAL, new Insets(5, 0, 0, 0), 0, 0));
	frame.getContentPane().add(centerPane);
	frame.pack();
	frame.setLocationByPlatform(true);
	frame.setVisible(true);
}

... and here is the output:

Thanks in advance!

Another component that is not a text component that would be interesting too: a combo box editable=false. When the user clicks, it would get the white background and the popup that is shown too.
All components could benefit from having these "focusXX" variants.
