Expand description
Specifies the direction for EventScroll
.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Up
the window is scrolled up.
Down
the window is scrolled down.
Left
the window is scrolled to the left.
Right
the window is scrolled to the right.
Smooth
the scrolling is determined by the delta values
in EventScroll
. See gdk_event_get_scroll_deltas()
. Since: 3.4
