## Detailed Description

Helper interface for Gtk::Constraint.

The ConstraintTarget interface is implemented by objects that can be used as source or target in Gtk::Constraints. Besides Gtk::Widget, it is also implemented by Gtk::ConstraintGuide.

Since gtkmm 3.96

## ◆ wrap()

Glib::RefPtr< Gtk::ConstraintTarget > wrap | ( | GtkConstraintTarget * | object,
|  | bool | take_copy = false )
| related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
