I have a composite widget, which contain many widgets (inside HorizontalPanel). How to disable all widgets inside HorizontalPanel or inside this composite? I can't find setEnabled() method in Composite or panels

getWidget() method of Composite class is protected, hence you cant access widgets inside composite from outside packages. Hence you can not get children widgets of Composite without subclassing Composite.

I'm sure you've already figured it out, but if anyone else is curious, this will enable or disable all nested FocusWidgets:

private void enableAllChildren(boolean enable, Widget widget)
{
    if (widget instanceof HasWidgets)
    {
        Iterator<Widget> iter = ((HasWidgets)widget).iterator();
        while (iter.hasNext())
        {
            Widget nextWidget = iter.next();
            enableAllChildren(enable, nextWidget);
            if (nextWidget instanceof FocusWidget)
            {
                ((FocusWidget)nextWidget).setEnabled(enable);
            }
        }
    }
}

The only way to do it is to recursively get all children of the panel and call setEnabled(false) on each widget, which extends FocusWidget
