_Conversion_HooksThis package provides an implementation for hooks used in Gtk.Type_Conversion. These hooks should be used when you import a new C GObject, so that GtkAda can recreate the Ada structure from the underlying C structure. Note that when you create a GObject directly in Ada, you do not need to provide any hook.
Implementation note: This is a separate package from Gtk.Type_Conversion so that adding a hook does not necessarily mean the user has to 'with' Gtk.Type_Conversion, and thus all the packages from GtkAda.
Note that this package is not thread safe. You should call the function Add_Hook from the elaboration part of your packages.
