Description: Reference for Gtk.ConstraintGuide

### Class

# GtkConstraintGuide

#### Description [src]

    final class Gtk.ConstraintGuide : GObject.Object {
      /* No available fields */
    }

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.
