Struct gdk::EventScroll
source · [−]pub struct EventScroll(_);
Expand description
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 ScrollDirection::Smooth
scroll direction. For
these, the scroll deltas can be obtained with
gdk_event_get_scroll_deltas()
.
