Actionable.setDetailedActionName

Sets the action-name and associated string target value of an actionable widget.

detailed_action_name is a string in the format accepted by [gio.action.Action.parseDetailedName].

(Note that prior to version 3.22.25, this function is only usable for actions with a simple "s" target, and detailed_action_name must be of the form "action::target" where action is the action name and target is the string to use as the target.)
