Member Function Documentation

Broadcast()

void PrefsListener::Broadcast ( int  id = 0 )

static

Call this static function to notify all PrefsListener objects.

Parameters

id

when positive, passed to UpdateSelectedPrefs() of all listeners, meant to indicate that only a certain subset of preferences have changed; else their UpdatePrefs() methods are called. (That is supposed to happen when the user OK's changes in the Preferences dialog.) Callbacks are delayed, in the main thread, using BasicUI::CallAfter

Definition at line 97 of file Prefs.cpp.

{
   BasicUI::CallAfter([id]{
      hub().Publish(id);
   });
}
