Implementations§

Source§

impl AlignConstraint

Source

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

Source

pub fn get_align_axis(&self) -> AlignAxis

Retrieves the value set using AlignConstraint::set_align_axis

§Returns

the alignment axis

Source

pub fn get_factor(&self) -> f32

Retrieves the factor set using AlignConstraint::set_factor

§Returns

the alignment factor

Source

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

Retrieves the source of the alignment

§Returns

the Actor used as the source of the alignment

Source

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

Source

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

Source

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

Source

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

Source

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

Source

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