Enum gtk4::Overflow

#[non_exhaustive]
pub enum Overflow {
    Visible,
    Hidden,
    // some variants omitted
}

Defines how content overflowing a given area should be handled.

This is used in WidgetExt::set_overflow(). The property::Widget::overflow property is modeled after the CSS overflow property, but implements it only partially.

Variants (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.

Visible

No change is applied. Content is drawn at the specified position.

Hidden

Content is clipped to the bounds of the area. Content outside the area is not drawn and cannot be interacted with.

Trait Implementations

impl Clone for Overflow

fn clone(&self) -> Overflow

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Overflow

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

Formats the value using the given formatter.

impl Display for Overflow

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

Formats the value using the given formatter.

impl<'a> FromValue<'a> for Overflow

type Checker = GenericValueTypeChecker<Overflow>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl Hash for Overflow

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,

Feeds a slice of this type into the given Hasher.

impl Ord for Overflow

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Overflow> for Overflow

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Overflow> for Overflow

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for Overflow

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for Overflow

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifer of self.

impl ValueType for Overflow

type Type = Overflow

Type to get the Type from.

impl Copy for Overflow

impl Eq for Overflow

impl StructuralEq for Overflow

impl StructuralPartialEq for Overflow
