--- Manage a notification action list.

|
|
-- A notification action is a "button" that will trigger an action on the sender
|
|
-- process. `notify-send` doesn't support actions, but `libnotify` based
|
|
-- applications do.

--@DOC_wibox_nwidget_actionlist_simple_EXAMPLE@

|
|
-- This example has a custom vertical widget template:
|
|
--
|
|
--@DOC_wibox_nwidget_actionlist_fancy_EXAMPLE@
|
|
--
|
|
-- This example has a horizontal widget template and icons:
|
|
--
|
|
--@DOC_wibox_nwidget_actionlist_fancy_icons_EXAMPLE@
|
|
--
|
|
-- This example uses the theme/style variables instead of the template. This is
|
|
-- less flexible, but easier to put in the theme file. Note that each style
|
|
-- variable has a `beautiful` equivalent.
