g-simple-action-group-remove (group name)

group -- a g-simple-action-group object
name -- a string with the name of the action

Removes the named action from the action group. If no action of this name is in the action group then nothing happens. The g-simple-action-group-remove function has been deprecated since version 2.38 and should not be used in newly written code. Use the g-action-map-remove-action function.
