Should these be passed the more specific event type?
It seems the user will always just reach into the union...

+  virtual void OnButtonNotify(WaylandEvent event) = 0;
+  virtual void OnKeyNotify(WaylandEvent event) = 0;
+  virtual void OnPointerFocus(WaylandEvent event) = 0;
+  virtual void OnKeyboardFocus(WaylandEvent event) = 0;
+
+  virtual void OnGeometryChange(WaylandEvent event) = 0;
+};
+
