How do I make a rich menu for an appindicator?

I'm adding menu items to an appindicator in pygtk. I don't want them to behave like ordinary menu items: I want them to have normal appearance, but not to respond to mouse hovers and mouse clicks. The way I imagine the new sound menu will behave.

In other words, I want to prevent the MenuItem selection that's going on below:

How do I go about doing that? What events should I swallow, or is there a better way?

Solution 1:

What I've done for StackApplet is to simply disable a menu item and use that as a 'header'. That way it doesn't respond to mouse clicks and looks like a static text label.

Solution 2:

Unfortunately, appindicator doesn't allow adding custom widget, as it requires GObject introspection. This will be available when ido package will have GObject instrospection.
