Details

class Gdk.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.ScrollDirection.SMOOTH scroll direction. For these, the scroll deltas can be obtained with Gdk.Event.get_scroll_deltas().
