GI.Gtk.Interfaces.BuilderScope

BuilderScope is an interface to provide support to Builder, primarily for looking up programming-language-specific values for strings that are given in a Builder UI file.

The primary intended audience is bindings that want to provide deeper integration of Builder into the language.

A BuilderScope instance may be used with multiple Builder objects, even at once.

By default, GTK will use its own implementation of BuilderScope for the C language which can be created via builderCScopeNew.

BuilderCScope instances use symbols explicitly added to builder with prior calls to builderCScopeAddCallbackSymbol. 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 Module’s introspective features (by opening the module Nothing) 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 builderCScopeAddCallbackSymbol is called for all signal callbacks which are referenced by the loaded XML, this functionality will require that Module be supported on the platform.

class (GObject o, IsDescendantOf BuilderScope o) => IsBuilderScope o

Type class for types which can be safely cast to BuilderScope, for instance with toBuilderScope.

Instances

(GObject o, IsDescendantOf BuilderScope o) => IsBuilderScope o

Defined in GI.Gtk.Interfaces.BuilderScope

toBuilderScope :: (MonadIO m, IsBuilderScope o) => o -> m BuilderScope

Cast to BuilderScope, for types for which this is known to be safe. For general casts, use castTo.
