Enum ScrollBarVisibility

pub enum ScrollBarVisibility {
    AlwaysHidden,
    VisibleWhenNeeded,
    AlwaysVisible,
}

Indicate whether the horizontal and vertical scroll bars must be always visible, hidden or visible when needed.

Variants

AlwaysHidden

Hide scroll bar even if they are needed.

You can still scroll, with the scroll-wheel and by dragging the contents, but there is no visual indication of how far you have scrolled.

VisibleWhenNeeded

Show scroll bars only when the content size exceeds the container, i.e. when there is any need to scroll.

This is the default.

AlwaysVisible

Always show the scroll bar, even if the contents fit in the container and there is no need to scroll.

Trait Implementations

impl Clone for ScrollBarVisibility

fn clone(&self) -> ScrollBarVisibility

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScrollBarVisibility

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ScrollBarVisibility

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ScrollBarVisibility

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ScrollBarVisibility

fn eq(&self, other: &ScrollBarVisibility) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
