#[non_exhaustive]
pub enum ScrollDirection {

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
