class Gtk::BuilderCScope

Overview

A Gtk::BuilderScope implementation for the C language.

Gtk::BuilderCScope instances use symbols explicitly added to @builder with prior calls to 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 nil) 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 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.

Constructor Detail

def self.new : self #

Creates a new Gtk::BuilderCScope object to use with future Gtk::Builder instances.

Calling this function is only necessary if you want to add custom callbacks via Gtk::BuilderCScope#add_callback_symbol.


Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def add_callback_symbol(callback_name : String, callback_symbol : GObject::Callback) : Nil #

Adds the @callback_symbol to the scope of @builder under the given @callback_name.

Using this function overrides the behavior of Gtk::Builder#create_closure for any callback symbols that are added. Using this method allows for better encapsulation as it does not require that callback symbols be declared in the global namespace.
