Enum gtk4::SizeRequestMode

#[non_exhaustive]
pub enum SizeRequestMode {
    HeightForWidth,
    WidthForHeight,
    ConstantSize,
}

Specifies a preference for height-for-width or width-for-height geometry management.

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.

HeightForWidth

Prefer height-for-width geometry management

WidthForHeight

Prefer width-for-height geometry management

ConstantSize

Don’t trade height-for-width or width-for-height

impl Ord for SizeRequestMode

fn cmp(&self, other: &SizeRequestMode) -> 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.

impl PartialEq<SizeRequestMode> for SizeRequestMode

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

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.
