Expand description
Constraint
describes a constraint between attributes of two widgets,
expressed as a linear equation.
The typical equation for a constraint is:
target.target_attr = source.source_attr × multiplier + constant
Each Constraint
is part of a system that will be solved by a
ConstraintLayout
in order to allocate and position each
child widget or guide.
The source and target, as well as their attributes, of a Constraint
instance are immutable after creation.
Properties
constant
The constant value to be added to the source-attribute
.
Readable | Writeable | Construct Only
multiplier
The multiplication factor to be applied to
the source-attribute
.
Readable | Writeable | Construct Only
relation
The order relation between the terms of the constraint.
Readable | Writeable | Construct Only
source
The source of the constraint.
The constraint will set the target-attribute
property of the target using the source-attribute
property of the source.
Readable | Writeable | Construct Only
source-attribute
The attribute of the source
read by the
constraint.
Readable | Writeable | Construct Only
strength
The strength of the constraint.
The strength can be expressed either using one of the symbolic values
of the ConstraintStrength
enumeration, or any positive integer
value.
Readable | Writeable | Construct Only
target
The target of the constraint.
The constraint will set the target-attribute
property of the target using the source-attribute
property of the source widget.
Readable | Writeable | Construct Only
target-attribute
The attribute of the target
set by the constraint.

pub fn new( target: Option<&impl IsA<ConstraintTarget>>, target_attribute: ConstraintAttribute, relation: ConstraintRelation, source: Option<&impl IsA<ConstraintTarget>>, source_attribute: ConstraintAttribute, multiplier: f64, constant: f64, strength: i32 ) -> Constraint
Creates a new constraint representing a relation between a layout attribute on a source and a layout attribute on a target.
target
the target of the constraint
target_attribute
the attribute of target
to be set
relation
the relation equivalence between target_attribute
and source_attribute
source
the source of the constraint
source_attribute
the attribute of source
to be read
multiplier
a multiplication factor to be applied to source_attribute
constant
a constant factor to be added to source_attribute
strength
the strength of the constraint
Returns
the newly created constraint
sourcepub fn new_constant(
target: Option<&impl IsA<ConstraintTarget>>,
target_attribute: ConstraintAttribute,
relation: ConstraintRelation,
constant: f64,
strength: i32
) -> Constraint
pub fn new_constant( target: Option<&impl IsA<ConstraintTarget>>, target_attribute: ConstraintAttribute, relation: ConstraintRelation, constant: f64, strength: i32 ) -> Constraint
Creates a new constraint representing a relation between a layout attribute on a target and a constant value.
target
a the target of the constraint
target_attribute
the attribute of target
to be set
relation
the relation equivalence between target_attribute
and constant
constant
a constant factor to be set on target_attribute
strength
the strength of the constraint
Returns
the newly created constraint
sourcepub fn builder() -> ConstraintBuilder
pub fn builder() -> ConstraintBuilder
Creates a new builder-pattern struct instance to construct Constraint
objects.
This method returns an instance of ConstraintBuilder
which can be used to create Constraint
objects.
sourcepub fn multiplier(&self) -> f64
pub fn multiplier(&self) -> f64
Retrieves the multiplication factor applied to the source attribute’s value.
Returns
a multiplication factor
sourcepub fn relation(&self) -> ConstraintRelation
pub fn relation(&self) -> ConstraintRelation
sourcepub fn source(&self) -> Option<ConstraintTarget>
pub fn source(&self) -> Option<ConstraintTarget>
Retrieves the ConstraintTarget
used as the source for the
constraint.
If the source is set to NULL
at creation, the constraint will use
the widget using the ConstraintLayout
as the source.
Returns
the source of the constraint
sourcepub fn source_attribute(&self) -> ConstraintAttribute
pub fn source_attribute(&self) -> ConstraintAttribute
sourcepub fn target(&self) -> Option<ConstraintTarget>
pub fn target(&self) -> Option<ConstraintTarget>
Retrieves the ConstraintTarget
used as the target for
the constraint.
If the targe is set to NULL
at creation, the constraint will use
the widget using the ConstraintLayout
as the target.
Returns
sourcepub fn target_attribute(&self) -> ConstraintAttribute
pub fn target_attribute(&self) -> ConstraintAttribute
sourcepub fn is_attached(&self) -> bool
pub fn is_attached(&self) -> bool
Checks whether the constraint is attached to a ConstraintLayout
,
and it is contributing to the layout.
Returns
TRUE
if the constraint is attached
sourcepub fn is_constant(&self) -> bool
pub fn is_constant(&self) -> bool
sourcepub fn is_required(&self) -> bool
