Struct AlignConstraint

pub struct AlignConstraint(/* private fields */);

Implementations

impl AlignConstraint

pub fn new<P: IsA<Actor>>( source: Option<&P>, axis: AlignAxis, factor: f32, ) -> AlignConstraint

Creates a new constraint, aligning a Actor’s position with regards of the size of the actor to source, with the given alignment factor

source

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

axis

the axis to be used to compute the alignment

factor

the alignment factor, between 0.0 and 1.0

Returns

the newly created AlignConstraint

pub fn get_align_axis(&self) -> AlignAxis

Retrieves the value set using AlignConstraint::set_align_axis

Returns

the alignment axis

pub fn get_factor(&self) -> f32

Retrieves the factor set using AlignConstraint::set_factor

Returns

the alignment factor

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

Retrieves the source of the alignment

Returns

the Actor used as the source of the alignment

pub fn set_align_axis(&self, axis: AlignAxis)

Sets the axis to which the alignment refers to

axis

the axis to which the alignment refers to

pub fn set_factor(&self, factor: f32)

Sets the alignment factor of the constraint

The factor depends on the AlignConstraint:align-axis property and it is a value between 0.0 (meaning left, when AlignConstraint:align-axis is set to AlignAxis::XAxis; or meaning top, when AlignConstraint:align-axis is set to AlignAxis::YAxis) and 1.0 (meaning right, when AlignConstraint:align-axis is set to AlignAxis::XAxis; or meaning bottom, when AlignConstraint:align-axis is set to AlignAxis::YAxis). A value of 0.5 aligns in the middle in either cases

factor

the alignment factor, between 0.0 and 1.0

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

Sets the source of the alignment constraint

source

a Actor, or None to unset the source

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

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

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

Trait Implementations

impl Clone for AlignConstraint

fn clone(&self) -> AlignConstraint

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Debug for AlignConstraint

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

Formats the value using the given formatter.

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for AlignConstraint

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

impl<T: ObjectType> PartialEq<T> for AlignConstraint

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

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.
