void(* _LV2_External_UI_Host::ui_closed

Callback that plugin UI will call when UI (GUI window) is closed by user.

This callback will be called during execution of LV2_External_UI_Widget::run() (i.e. not from background thread).

After this callback is called, UI is defunct. Host must call LV2UI_Descriptor::cleanup(). If host wants to make the UI visible again, the UI must be reinstantiated.

Optional (may be NULL) "user friendly" identifier which the UI may display to allow a user to easily associate this particular UI instance with the correct plugin instance as it is represented by the host (e.g.

"track 1" or "channel 4").

If supplied by host, the string will be referenced only during LV2UI_Descriptor::instantiate()
