Detailed Description

An invisible constraint target.

A ConstraintGuide is an invisible layout element that can be used by widgets inside a Gtk::ConstraintLayout as a source or a target of a Gtk::Constraint. Guides can be used like guidelines or as flexible space.

Unlike a Gtk::Widget, a Gtk::ConstraintGuide will not be drawn.

Since gtkmm 3.96:
