Action.changeState

Request for the state of action to be changed to value.

The action must be stateful and value must be of the correct type. See [gio.action.Action.getStateType].

This call merely requests a change. The action may refuse to change its state or may change its state to something other than value. See [gio.action.Action.getStateHint].

If the value GVariant is floating, it is consumed.
