Object methods

:setup {[args]} · Inherited from wibox.widget
Set a declarative widget hierarchy description. See The declarative layout system

Parameters:

  • args An array containing the widgets disposition
:add_button (button) · Inherited from wibox.widget
Add a new awful.button to this widget.

Parameters:

  • button awful.button The button to add.
:emit_signal_recursive (signal_name, ...) · Inherited from wibox.widget
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.

Parameters:

  • signal_name string
  • ... Other arguments
:emit_signal (name, ...) · Inherited from gears.object
Emit a signal.

Parameters:

  • 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().
:connect_signal (name, func) · Inherited from gears.object
Connect to a signal.

Parameters:

  • name string The name of the signal.
  • func function The callback to call when the signal is emitted.
:weak_connect_signal (name, func) · Inherited from gears.object
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.

Parameters:

  • name string The name of the signal.
  • func function The callback to call when the signal is emitted.

Signals

widget::layout_changed · Inherited from wibox.widget
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 This signal is emitted when the previous results of :layout() and :fit() are no longer valid.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.
