------------
-- Quarks --
------------
type GQuark is new Guint32;
-- Represents a string internally in GtkAda. Once you know the
-- equivalent for a string, you can always use it instead of the string,
-- which provides a faster access for all the functions that use htables
-- in GtkAda.
-- There is a global htable that contains all the quarks defined in
-- your application and GtkAda itself.
Unknown_Quark : constant GQuark := 0;
function Quark_From_String (Id : String) return GQuark;

-- Note that if the quark does not already exist, an entry is created for

----------------
-- Properties --
----------------
-- This is only the definition of the property types. See Glib.Properties
-- on how to get and set the value of properties for specific objects, or
-- the package Glib.Properties.Creation for information on how to create
-- new properties in your own widgets.
-- Introspection is available, ie from an existing object you can find out
-- the list of properties it supports. See the functions
-- Glib.Object.Interface_List_Properties and
-- Glib.Object.Class_List_Properties
type Property (<>) is private;
function Build (Name : String) return Property;
-- You should use this function only if you are creating new widgets, and
-- their properties. Normal usage of properties doesn't require the use
-- of this function.
-- An ASCII.NUL character is automatically appended if necessary
function Property_Name (Prop : Property) return String;
-- Return the name of the property.
-- This name includes the trailing ASCII.Nul, and thus can be passed as is
-- to C.
type Param_Spec is new Glib.C_Proxy;
type Param_Spec_Array is array (Natural range <>) of Param_Spec;
-- See Glib.Properties.Creation for more information on this type
type Param_Flags is mod 2 ** 6;

-- These are the various flags that help define if, and when, a property
-- can be read and modified.
-----------
-- GType --
-----------
type GType is new Gsize;
-- This type describes an internal type in Glib.
-- You shouldn't have to use it in your own applications, however it might
-- be useful sometimes.
-- Every object type is associated with a specific value, created
-- dynamically at run time the first time you instantiate an object of that
-- type (thus if you have never used e.g a Gtk_File_Selection, it won't
-- have any GType associated with it).
-- You can get the exact type value for each type by using the functions
-- Get_Type provided in all the packages in GtkAda.
-- You can get the specific value for an existing widget by using the
-- function Glib.Object.Get_Type.
type GType_Class is private;
-- An opaque structure used as the base for all classes in glib and gtk+.
-- See also Glib.Object.GObject_Class for a more useful child of this
-- type.
type GType_Array is array (Guint range <>) of Glib.GType;
function Parent (Typ : GType) return GType;
-- Return the parent type of Typ (eg if Typ is associated with a Gtk
-- widget, it returns the typ of its parent).
function Fundamental (Typ : GType) return GType;
-- Return the fundamental type for Type. In gtk+, the types are organized
-- into several hierarchies, similar to what is done for widgets.
-- All of these hierarchies are based on one of the fundamental types
-- defined below.
-- This function returns that fundamental type.
--
-- For instance, each enumeration type in gtk+ has its own GType.
-- However, Fundamental will return GType_Enum in all of these cases.
function Type_Name (Type_Num : GType) return String;
-- Return the name of the type (enumeration,...) associated with Typ.
-- If Fundamental (Typ) return GType_Enum, this returns the name of
-- the enumeration type that Typ represents.
-- This might be useful in debug messages.
function Type_From_Name (Name : String) return GType;
-- Convert a string to the matching type.
-- Name should be the C GObject name rather than the Ada name: thus,
-- use names such as GtkScrollbar or GtkButton for widgets.
function Get_Qdata (Typ : GType; Quark : GQuark) return Glib.C_Proxy;
-- Return the user data set for Typ
procedure Set_Qdata
(Typ : GType;
Quark : GQuark;
Data : Glib.C_Proxy);
-- Associate some named data with Typ.
-- The list of fundamental types defined in Glib. As opposed to most other
-- types (for instance the ones used for widgets), the types have static
-- values, always the same.

-----------------
-- Boxed types --
-----------------
-- Boxed types are a convenient way to encapsulate Ada types through a C
-- layer. An initialization and a finalization function can be provided.
-- The most frequent usage of such types is in argument to signals and
-- handlers (See the functions in Glib.Values), or to store such types
-- in a Gtk_Tree_Model. This allows you for instance to store reference
-- counted types where you want to be able to control what should happen
-- when the cell is removed from the tree.
--
-- See an example with the subprogram Glib.Values.Set_Boxed
GType_Boxed : constant GType := 18 * (2 ** GType_Fundamental_Shift);
-- The base type for all boxed types. In tree models, you should use the
-- actual type returned by Boxed_Type_Register_Static.
type Boxed_Copy is access
function (Boxed : System.Address) return System.Address;

type Boxed_Free is access procedure (Boxed : System.Address);

type C_Dummy is record

-- anyway. Pretend it contains an address so that the compiler a
