My question is this: Default change the color to give a JTextField setEnabled (false) for example is black and proven with UIManager results but have not had any suggestions.
Greetings.
To change disabled background color try this:
UIManager.put("TextField.disabledBackground", Color.GRAY);
You can change disabled text color using setDisabledTextColor, i.e.:
textField.setDisabledTextColor(Color.GRAY);
EDIT: include SSCCE
import java.awt.Color;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.UIManager;
public class TestDisabledTextField {
public static void main(String[] args) {
UIManager.put("TextField.disabledBackground", Color.YELLOW);
JTextField textField = new JTextField("Disabled text field", 15);
textField.setEnabled(false);
textField.setDisabledTextColor(Color.RED);
JPanel panel = new JPanel();
panel.add(textField);
JOptionPane.showMessageDialog(null, panel);
}
}
