Enum ScrollbarVisibilityMode 

#[repr(C)]
pub enum ScrollbarVisibilityMode {
    Always = 0,
    WhenScrolling = 1,
    Auto = 2,
}

Controls when the scrollbar is displayed.

This is a per-element CSS property (-azul-scrollbar-visibility) that determines the scrollbar presentation style. It interacts with the OS-level ScrollbarPreferences.visibility (from System Preferences) when set to Auto.

• Always: Classic, always-visible scrollbar (Chrome/Windows/Linux default). Scrollbar reserves layout space.
• WhenScrolling: Overlay scrollbar that fades in on scroll activity and fades out after a delay. Does not reserve layout space.
• Auto: Use the OS preference. On macOS this typically means WhenScrolling, on Windows/Linux this typically means Always.

Variants

Always = 0

Scrollbar is always visible (Chrome/Windows/Linux default). Reserves layout space.

WhenScrolling = 1

Scrollbar appears on scroll and fades out after inactivity. Does not reserve layout space (overlay).

Auto = 2

Use the OS-level scrollbar preference.

Trait Implementations

fn clone(&self) -> ScrollbarVisibilityMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollbarVisibilityMode

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

Formats the value using the given formatter.

impl Default for ScrollbarVisibilityMode

fn default() -> ScrollbarVisibilityMode

Returns the “default value” for a type.

impl FormatAsRustCode for ScrollbarVisibilityMode

fn format_as_rust_code(&self, _tabs: usize) -> String

impl From<ScrollbarVisibilityMode> for CssProperty

fn from(e: ScrollbarVisibilityMode) -> Self

Converts to this type from the input type.

impl Hash for ScrollbarVisibilityMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for ScrollbarVisibilityMode

fn cmp(&self, other: &ScrollbarVisibilityMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ScrollbarVisibilityMode

fn eq(&self, other: &ScrollbarVisibilityMode) -> 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.

fn partial_cmp(&self, other: &ScrollbarVisibilityMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
