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 This signal is emitted when the previous results of :layout()and:fit()are no longer valid.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:
- widget::redraw_needed
- 
    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
 :layout()and:fit()would still return the same results as before.See also:

Methods
- wibox.container.mirror:get_children ()
- 
    Get the number of children element
    Returns:- 
           table
        The children
    
 
- wibox.container.mirror:set_children (children)
- 
    Replace the layout children
 This layout only accept one children, all others will be ignored
    - children table A table composed of valid widgets
 
- wibox.container.mirror:reset ()
- Reset this layout. The widget will be removed and the axes reset.
- wibox.container.mirror:get_all_children ()
- 
    Get all direct and indirect children widgets.
 This will scan all containers recursively to find widgets
 Warning: This method it prone to stack overflow id the widget, or any of its
 children, contain (directly or indirectly) itself.
    Returns:- 
           table
        The children
    
 
- wibox.container.mirror:setup (args)
- 
    Set a declarative widget hierarchy description.
 See The declarative layout system
    - args An array containing the widgets disposition
 
- wibox.container.mirror:buttons (_buttons)
- 
    Set/get a widget's buttons.
    - _buttons The table of buttons that should bind to the widget.
 
- wibox.container.mirror:emit_signal_recursive (signal_name, ...)
- 
    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.mirror:emit_signal (name, ...)
- 
    Emit a signal.
    - name string The name of the signal.
- ... Extra arguments for the callback functions. Each connected function receives the object as first argument and then any extra arguments that are given to emit_signal().
 
- wibox.container.mirror: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.mirror: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.
