class: BuilderCScope

[22:7] extends: object

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.

Methods

• BuilderCScope ()

  Creates a new GtkBuilderCScope object to use with future GtkBuilder instances. Calling this function is only necessary if you want to add custom callbacks via [method@Gtk.BuilderCScope.add_callback_symbol].

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asObject ()

  Wraps this handle as Object.

  • @r A Object object.

• asBuilderScope ()

  Wraps this handle as BuilderScope.

  • @r A BuilderScope object.
