Signals
- widget::layout_changed
- 
    When the layout (size) change.
 This signal is emitted when the previous results of :layout()and:fit()are no longer valid. Unless this signal is emitted,:layout()and:fit()must return the same result when called with the same arguments.See also:

- 
    When the widget content changed.
 This signal is emitted when the content of the widget changes. The widget will
 be redrawn, it is not re-layouted. Put differently, it is assumed that

    Emit a signal and ensure all parent widgets in the hierarchies also
 forward the signal.  This is useful to track signals when there is a dynamic
 set of containers and layouts wrapping the widget.
    - signal_name string
- ... Other arguments
 
- wibox.container.margin:disconnect_signal (name, func)
- 
    Disconnect to a signal.

- wibox.container.margin:emit_signal (name, ...)
- 
    Emit a signal.
    - name string The name of the signal

- wibox.container.margin:connect_signal (name, func)
- 
    Connect to a signal.
    - name string The name of the signal
- func function The callback to call when the signal is emitted
 
- wibox.container.margin:weak_connect_signal (name, func)
- 
    Connect to a signal weakly.  This allows the callback function to be garbage
 collected and automatically disconnects the signal when that happens.
Warning: Only use this function if you really, really, really know what you are doing. - name string The name of the signal
- func function The callback to call when the signal is emitted
