Implementations

impl SnapConstraint

pub fn new<P: IsA<Actor>>( source: Option<&P>, from_edge: SnapEdge, to_edge: SnapEdge, offset: f32, ) -> SnapConstraint

Creates a new SnapConstraint that will snap a Actor to the edge of source, with the given offset.

source

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

from_edge

the edge of the actor to use in the constraint

to_edge

the edge of source to use in the constraint

offset

the offset to apply to the constraint, in pixels

Returns

the newly created SnapConstraint

pub fn get_edges(&self) -> (SnapEdge, SnapEdge)

Retrieves the edges used by the self

from_edge

return location for the actor’s edge, or None

to_edge

return location for the source’s edge, or None

pub fn get_offset(&self) -> f32

Retrieves the offset set using SnapConstraint::set_offset

Returns

the offset, in pixels

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

Retrieves the Actor set using SnapConstraint::set_source

Returns

a pointer to the source actor

pub fn set_edges(&self, from_edge: SnapEdge, to_edge: SnapEdge)

Sets the edges to be used by the self

The from_edge is the edge on the Actor to which self has been added. The to_edge is the edge of the Actor inside the SnapConstraint:source property.

from_edge

the edge on the actor

to_edge

the edge on the source

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

pub fn get_property_from_edge(&self) -> SnapEdge

The edge of the Actor that should be snapped

pub fn set_property_from_edge(&self, from_edge: SnapEdge)

The edge of the Actor that should be snapped

pub fn get_property_to_edge(&self) -> SnapEdge

The edge of the SnapConstraint:source that should be snapped

pub fn set_property_to_edge(&self, to_edge: SnapEdge)

The edge of the SnapConstraint:source that should be snapped

pub fn connect_property_from_edge_notify<F: Fn(&SnapConstraint) + 'static>( &self, f: F, ) -> SignalHandlerId

pub fn connect_property_offset_notify<F: Fn(&SnapConstraint) + 'static>( &self, f: F, ) -> SignalHandlerId

pub fn connect_property_source_notify<F: Fn(&SnapConstraint) + 'static>( &self, f: F, ) -> SignalHandlerId

pub fn connect_property_to_edge_notify<F: Fn(&SnapConstraint) + 'static>( &self, f: F, ) -> SignalHandlerId

Trait Implementations

impl Clone for SnapConstraint

fn clone(&self) -> SnapConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapConstraint

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

Formats the value using the given formatter.

impl Display for SnapConstraint

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

Formats the value using the given formatter.

impl Hash for SnapConstraint

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 SnapConstraint

fn cmp(&self, other: &SnapConstraint) -> 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 SnapConstraint

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 SnapConstraint

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 SnapConstraint

fn static_type() -> Type

Returns the type identifier of Self.
