Expand description
A builder-pattern type to construct Constraint
objects.
Implementations§
source§impl ConstraintBuilder
impl ConstraintBuilder
sourcepub fn constant(self, constant: f64) -> Self
pub fn constant(self, constant: f64) -> Self
The constant value to be added to the source-attribute
.
sourcepub fn multiplier(self, multiplier: f64) -> Self
pub fn multiplier(self, multiplier: f64) -> Self
The multiplication factor to be applied to
the source-attribute
.
sourcepub fn relation(self, relation: ConstraintRelation) -> Self
pub fn relation(self, relation: ConstraintRelation) -> Self
The order relation between the terms of the constraint.
sourcepub fn source(self, source: &impl IsA<ConstraintTarget>) -> Self
pub fn source(self, source: &impl IsA<ConstraintTarget>) -> Self
The source of the constraint.
The constraint will set the target-attribute
property of the target using the source-attribute
property of the source.
sourcepub fn source_attribute(self, source_attribute: ConstraintAttribute) -> Self
pub fn source_attribute(self, source_attribute: ConstraintAttribute) -> Self
The attribute of the source
read by the
constraint.
sourcepub fn strength(self, strength: i32) -> Self
pub fn strength(self, strength: i32) -> Self
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.
sourcepub fn target(self, target: &impl IsA<ConstraintTarget>) -> Self
pub fn target(self, target: &impl IsA<ConstraintTarget>) -> Self
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.
sourcepub fn target_attribute(self, target_attribute: ConstraintAttribute) -> Self
pub fn target_attribute(self, target_attribute: ConstraintAttribute) -> Self
The attribute of the target
set by the constraint.
sourcepub fn build(self) -> Constraint
pub fn build(self) -> Constraint
Build the Constraint
.
