Object methods

:reset ()

Reset this layout. The widget will be removed and the rotation reset.

: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
