GI.Gdk.Structs.EventScroll

Generated from button presses for the buttons 4 to 7. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.

Some GDK backends can also generate “smooth” scroll events, which can be recognized by the %GDK_SCROLL_SMOOTH scroll direction. For these, the scroll deltas can be obtained with gdk_event_get_scroll_deltas().
