* The #GdkEvent struct contains a union of all of the event structs,

* The event type is always the first field in all of the event structs, and
* can always be accessed with the following code, no matter what type of

* <informalexample>
* <programlisting>
* GdkEvent *event;
* GdkEventType type;
*
* type = event->type;
* </programlisting>

*
* To access other fields of the event structs, the pointer to the event
* can be cast to the appropriate event struct pointer, or the union member
* name can be used. For example if the event type is %GDK_BUTTON_PRESS
* then the x coordinate of the button press can be accessed with:
* <informalexample>
* <programlisting>
* GdkEvent *event;
* gdouble x;
