>From the development branch:
typedef enum
{
GDK_SCROLL_UP,
GDK_SCROLL_DOWN,
GDK_SCROLL_LEFT,
GDK_SCROLL_RIGHT
} GdkScrollDirection;
struct _GdkEventScroll
{
GdkEventType type;
GdkWindow *window;
gint8 send_event;
guint32 time;
gdouble x;
gdouble y;
guint state;
GdkScrollDirection direction;
GdkDevice *device;
gdouble x_root, y_root;
};
Making the exact mechanism for generating scroll events customizable
should be easy, though it isn't currently.
