Java Swing: Enabling/Disabling all components in JPanel

Question

I have a JPanel which contains a JToolbar (including few buttons without text) and a JTable and I need to enable/disable (make internal widgets not clickable). I tried this:

Answer 1

I used the following function:

void setPanelEnabled(JPanel panel, Boolean isEnabled) {
    panel.setEnabled(isEnabled);

    Component[] components = panel.getComponents();

    for(int i = 0; i < components.length; i++) {
        if(components[i].getClass().getName() == "javax.swing.JPanel") {
            setPanelEnabled((JPanel) components[i], isEnabled);
        }

        components[i].setEnabled(isEnabled);
    }
}
