This retrieves the GtkType object for a given
GtkObject or directly by name.
This can be used to dynamically discover information
about a Gtk class such as its signals, properties,
inheritance hierarchy, etc.
gtkGetType(name)
gtkObjectGetType(w, check=TRUE)w object inherits from GtkObject.
Typically one passes TRUE for this. It is useful
when one gets an incomplete object constructed directly in C code
and we want to construct its class information
(gtkObjectGetClasses) manually. names
vector for the numeric vector.
gtkGetType with a string
giving the name of the Gtk class, the associated
Gtk class must have been initialized first.
Specifically an object of that class
must have been created earlier or
the associated gtk__get_type
called.
This can be done using the .C
function as in .C("gtk_button_get_type", PACKAGE= "RGtk").
