BuilderCScope

Object Hierarchy:

Description:

[ CCode ( type_id = "gtk_builder_cscope_get_type ()" ) ]
public class BuilderCScope : Object, BuilderScope

A `GtkBuilderScope` implementation for the C language.

`GtkBuilderCScope` instances use symbols explicitly added to builder with prior calls to [ method@Gtk.BuilderCScope.add_callback_symbol]. If developers want to do that, they are encouraged to create their own scopes for that purpose.

In the case that symbols are not explicitly added; GTK will uses `GModule`’s introspective features (by opening the module null) to look at the application’s symbol table. From here it tries to match the signal function names given in the interface description with symbols in the application.

Note that unless [method@Gtk.BuilderCScope.add_callback_symbol] is called for all signal callbacks which are referenced by the loaded XML, this functionality will require that `GModule` be supported on the platform.
