Enclosing interface:

LayoutEvents
```
public static interface LayoutEvents.LayoutClickNotifier
extends Serializable
```
The interface for adding and removing LayoutClickEvent listeners. By implementing this interface a class explicitly announces that it will generate a LayoutClickEvent when a component inside it is clicked and a LayoutClickListener is registered.
Note: The general Java convention is not to explicitly declare that a class generates events, but to directly define the addListener and removeListener methods. That way the caller of these methods has no real way of finding out if the class really will send the events, or if it just defines the methods to be able to implement an interface.

6.5.2

- Method Detail
  - addLayoutClickListener
```
Registration addLayoutClickListener(LayoutEvents.LayoutClickListener listener)
```
    Add a click listener to the layout. The listener is called whenever the user clicks inside the layout. An event is also triggered when the click targets a component inside a nested layout or Panel, provided the targeted component does not prevent the click event from propagating. A caption is not considered part of a component. The child component that was clicked is included in the LayoutEvents.LayoutClickEvent.
    
    Parameters:
    
    listener - The listener to add
    
    Returns:
    
    a registration object for removing the listener
