Struct gtk4::ConstraintBuilder[][src]

pub struct ConstraintBuilder { /* fields omitted */ }
Expand description

A builder-pattern type to construct Constraint objects.

Implementations

Create a new ConstraintBuilder.

Build the Constraint.

The constant value to be added to the property::Constraint::source-attribute.

The multiplication factor to be applied to the property::Constraint::source-attribute.

The order relation between the terms of the constraint.

The source of the constraint.

The constraint will set the property::Constraint::target-attribute of the target using the property::Constraint::source-attribute of the source.

The attribute of the property::Constraint::source read by the constraint.

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.

The target of the constraint.

The constraint will set the property::Constraint::target-attribute of the target using the property::Constraint::source-attribute of the source widget.

The attribute of the property::Constraint::target set by the constraint.
