Implementations

impl BindConstraint

pub fn new<P: IsA<Actor>>( source: Option<&P>, coordinate: BindCoordinate, offset: f32, ) -> BindConstraint

Creates a new constraint, binding a Actor’s position to the given coordinate of the position of source

source

the Actor to use as the source of the binding, or None

coordinate

the coordinate to bind

offset

the offset to apply to the binding, in pixels

Returns

the newly created BindConstraint

pub fn get_coordinate(&self) -> BindCoordinate

Retrieves the bound coordinate of the constraint

Returns

the bound coordinate

pub fn get_offset(&self) -> f32

Retrieves the offset set using BindConstraint::set_offset

Returns

the offset, in pixels

pub fn get_source(&self) -> Option<Actor>

Retrieves the Actor set using BindConstraint::set_source

Returns

a pointer to the source actor

pub fn set_coordinate(&self, coordinate: BindCoordinate)

Sets the coordinate to bind in the constraint

coordinate

the coordinate to bind

pub fn set_offset(&self, offset: f32)

Sets the offset to be applied to the constraint

offset

the offset to apply, in pixels

pub fn set_source<P: IsA<Actor>>(&self, source: Option<&P>)

Sets the source Actor for the constraint

source

a Actor, or None to unset the source

Trait Implementations

impl Clone for BindConstraint

fn clone(&self) -> BindConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindConstraint

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

Formats the value using the given formatter.

impl Display for BindConstraint

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

Formats the value using the given formatter.

impl Hash for BindConstraint

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 BindConstraint

fn cmp(&self, other: &BindConstraint) -> 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<T: ObjectType> PartialEq<T> for BindConstraint

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

impl<T: ObjectType> PartialOrd<T> for BindConstraint

fn partial_cmp(&self, other: &T) -> 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.

impl StaticType for BindConstraint

fn static_type() -> Type

Returns the type identifier of Self.
