Gtk.ConstraintGuide – gtk4 – Vala Binding Reference

Description:

[ CCode ( type_id = "gtk_constraint_guide_get_type ()" ) ]
public class ConstraintGuide : Object, ConstraintTarget

A `GtkConstraintGuide` is an invisible layout element in a `GtkConstraintLayout`.

The `GtkConstraintLayout` treats guides like widgets. They can be used as the source or target of a `GtkConstraint`.

Guides have a minimum, maximum and natural size. Depending on the constraints that are applied, they can act like a guideline that widgets can be aligned to, or like *flexible space*.

Unlike a `GtkWidget`, a `GtkConstraintGuide` will not be drawn.
