| typedef void(*)(gpointer data | DestroyNotify) | 
Self-contained handler of series of events.
This is an abstract base class, low-level implementation for event controllers. Those react to a series of Gdk::Events, and possibly trigger actions as a consequence of those.

 | noexcept | 
| 
 | overridenoexcept | 
| 
 | protected | 
There is no create() method that corresponds to this constructor, because only derived classes shall be created.
| Glib::RefPtr< const Gdk::Event > Gtk::EventController::get_current_event | ( | ) | const | 
Returns the event that is currently being handled by the controller.
At other times, nullptr is returned.
| Glib::RefPtr< Gdk::Device > Gtk::EventController::get_current_event_device | ( | ) |
