    Description copied from interface: HasMenuItems
    
    Adds a new item component with the given text content and click listener to the context menu overlay.
    This is a convenience method for the use case where you have a list of highlightable MenuItems inside the overlay. If you want to configure the contents of the overlay without wrapping them inside MenuItems, or if you just want to add some non-highlightable components between the items, use the ContextMenuBase.add(Component...) method.

    addItem in interface HasMenuItems
    
    Parameters:
    
    text - the text content for the new item
