Take the following example code. There is some bug in Swing which doesn't render disabled components as disabled if the component contains HTML. Aside from reporting the issue, which I hope a colleague has already taken care of, is there some good way to work around the problem?
Whatever solution I take, I want it to be a global fix as opposed to something that needs to be hacked into every check box in the application.
I tried making a custom UI for the check box which calls setForeground before and after the painting, but it turns out that by calling setForeground, it fires an event which ultimately results in it calling repaint(), which calls the renderer, ...

import java.util.Arrays;

import javax.swing.SwingUtilities;
public class TestCheckBoxes extends JFrame
{
public TestCheckBoxes()
{
JCheckBox checkBox1 = new JCheckBox("Enabled, plain text");
JCheckBox checkBox2 = new JCheckBox("<html><p>Enabled, HTML");
JCheckBox checkBox3 = new JCheckBox("Disabled, plain text");
checkBox3.setEnabled(false);
JCheckBox checkBox4 = new JCheckBox("<html><p>Disabled, HTML");
checkBox4.setEnabled(false);
setLayout(new GridLayout(4, 1));
for (JCheckBox checkBox : Arrays.asList(checkBox1, checkBox2, checkBox3, checkBox4))
{
checkBox.setBorder(BorderFactory.createEmptyBorder(8, 8, 8, 8));
add(checkBox);
}
((JComponent) getContentPane()).setBorder(BorderFactory.createEmptyBorder(8, 8, 8, 8));
pack();
}
public static void main(String[] args)
{
SwingUtilities.invokeLater(new Runnable()
{
@Override
public void run()
{
TestCheckBoxes frame = new TestCheckBoxes();
frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
frame.setVisible(true);
}
});
}
