EventScrollProtocol

public protocol EventScrollProtocol

The EventScrollProtocol protocol exposes the methods and properties of an underlying GdkEventScroll instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see EventScroll. Alternatively, use EventScrollRef as a lighweight, unowned reference if you already have an instance you just want to use.

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().
