Object methods

🔗 :reset ()

Reset this layout.

The widget will be removed and the rotation reset.

🔗 :add_button (button) · Inherited from wibox.widget.base

Add a new awful.button to this widget.

Parameters:

Name		Type(s)	Description
button		awful.button	The button to add.

🔗 :emit_signal_recursive (signal_name, ...) · Inherited from wibox.widget.base

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.

Note that this function has some flaws:

The signal is only forwarded once the widget tree has been built. This happens after all currently scheduled functions have been executed. Therefore, it will not start to work right away.
In case the widget is present multiple times in a single widget tree, this function will also forward the signal multiple times (once per upward tree path).
If the widget is removed from the widget tree, the signal is still forwarded for some time, similar to the first case.

Parameters:

Name		Type(s)	Description
signal_name		string
...			Other arguments

🔗 :index (widget, recursive, ...) -> (number, widget, table) · Inherited from wibox.widget.base

Get the index of a widget.

Parameters:

Name		Type(s)	Description
widget		widget	The widget to look for.
recursive	Optional	boolean	Recursively check accross the sub-widgets hierarchy.
...	Optional	widget	Additional widgets to add at the end of the sub-widgets hierarchy "path".

Returns:

number The widget index.
widget The parent widget.
table The hierarchy path between "self" and "widget".

🔗 :connect_signal (name, func) · Inherited from gears.object

Connect to a signal.

Usage example output:

In slot [obj]   nil nil nil
In slot [obj]   foo bar 42

Parameters:

Name		Type(s)	Description
name		string	The name of the signal.
func		function	The callback to call when the signal is emitted.

Usage:

local o = gears.object{}
-- Function can be attached to signals
local function slot(obj, a, b, c)
    print("In slot", obj, a, b, c)
end
o:connect_signal("my_signal", slot)
-- Emitting can be done without arguments. In that case, the object will be
-- implicitly added as an argument.
o:emit_signal "my_signal"
-- It is also possible to add as many random arguments are required.
o:emit_signal("my_signal", "foo", "bar", 42)
-- Finally, to allow the object to be garbage collected (the memory freed), it
-- is necessary to disconnect the signal or use weak_connect_signal
o:disconnect_signal("my_signal", slot)
-- This time, the slot wont be called as it is no longer connected.
o:emit_signal "my_signal"

🔗 :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		Type(s)	Description
name		string	The name of the signal.
func		function	The callback to call when the signal is emitted.

🔗 :disconnect_signal (name, func) · Inherited from gears.object

Disconnect from a signal.

Parameters:

Name		Type(s)	Description
name		string	The name of the signal.
func		function	The callback that should be disconnected.

🔗 :emit_signal (name, ...) · Inherited from gears.object

Emit a signal.

Parameters:

Name		Type(s)	Description
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()

Signals

🔗 widget::layout_changed · Inherited from wibox.widget.base
