Type: GtkConstraintTarget

The source of the constraint.

The argument can be NULL.

The data is owned by the caller of the function.

source_attribute

Type: GtkConstraintAttribute

The attribute of source to be read.

multiplier

Type: double

A multiplication factor to be applied to source_attribute.

constant

Type: double

A constant factor to be added to source_attribute.

strength

Type: int

The strength of the constraint.

Return value

Type: GtkConstraint
