Enum gtk::SelectionMode

#[non_exhaustive]
pub enum SelectionMode {
    None,
    Single,
    Browse,
    Multiple,
    // some variants omitted
}

Used to control what selections users are allowed to make.

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.

None

No selection is possible.

Single

Zero or one element may be selected.

Browse

Exactly one element is selected. In some circumstances, such as initially or during a search operation, it’s possible for no element to be selected with Browse. What is really enforced is that the user can’t deselect a currently selected element except by selecting another element.

Multiple

Any number of elements may be selected. The Ctrl key may be used to enlarge the selection, and Shift key to select between the focus and the child pointed to. Some widgets may also allow Click-drag to select a range of elements.

Trait Implementations

impl Clone for SelectionMode

fn clone(&self) -> SelectionMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionMode

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

Formats the value using the given formatter.

impl Display for SelectionMode

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

Formats the value using the given formatter.

impl<'a> FromValue<'a> for SelectionMode

type Checker = GenericValueTypeChecker<SelectionMode>

Value type checker.

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

Get the contained value from a Value.

impl Hash for SelectionMode

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,

Feeds a slice of this type into the given Hasher.

impl Ord for SelectionMode

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<SelectionMode> for SelectionMode

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

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

const 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<SelectionMode> for SelectionMode

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

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

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

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

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

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

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

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

const 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 SelectionMode

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for SelectionMode

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 SelectionMode

type Type = SelectionMode

Type to get the Type from.

impl Copy for SelectionMode
