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
-
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are no longer valid.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 · Inherited from wibox.widget
-
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:
