The Xfce Foundation Classes, a C++ binding, wraps a GdkEvent pointer in a C++ wrapper class called Gdk::Event. Each event type then has its own class that derives from Gdk::Event, via an intermediate class called Gdk::EventAny. Gdk::Event provides public accessor functions that cast the Gdk::Event base class to the correct derived event class type, or null, depending on the GdkEventType field.[snip]
So, how do language bindings handle GdkEvent currently ?
Each derived event class has an accessor function that returns the base class' stored GdkEvent pointer cast to a pointer the corresponding GDK event struct type, such as a GdkEventButton or GdkEventMotion pointer. Each event class type provides accessor functions for the corresponding GDK struct fields. In the XFC Gtk::Widget event signal handlers each GdkEvent pointer is wrapped in the appropriate XFC event class type before passing it to the user defined event signal handling function.
