gtk:constraint-new (target target-attribute relation source source-attribute multiplier constant strength)

target -- a gtk:constraint-target object
target-attribute -- a gtk:constraint-attribute value for the attribute of target to be set
relation -- a gtk:constraint-relation value for the relation equivalence between target-attribute and source-attribute
source -- a gtk:constraint-target object
source-attribute -- a gtk:constraint-attribute value for the attribute of source to be set
multiplier -- a number coerced to a double float for a multiplication factor to be applied to source-attribute
constant -- a number coerced to a double float for a constant factor to be added to source-attribute
strength -- a gtk:constraint-strength value for the strength of the constraint

The newly created gtk:constraint object.

Creates a new gtk:constraint object representing a relation between a layout attribute on a source and a layout attribute on a target.
