Package Glib

This package provides definitions for the basic types used in Glib, Gdk and Gtk.

Types

type Boolean_Array is array (Natural range <>) of Boolean;




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.


type Gboolean is new Gint;




type Gboolean_Array is array (Natural range <>) of Gboolean;




type Gchar is new C.char;




type Gdouble is new C.double;




type Gdouble_Array is array (Natural range <>) of Gdouble;




type Gfloat is new C.C_float;




type Gfloat_Array is array (Natural range <>) of Gfloat;




type Gint is new C.int;




subtype Gint16 is Gint range -(2 ** 15) .. (2 ** 15 - 1);




subtype Gint32 is Gint range -(2 ** 31) .. (2 ** 31 - 1);




subtype Gint8 is Gint range -(2 ** 7) .. (2 ** 7 - 1);




type Gint_Array is array (Natural range <>) of Gint;




type Glong is new C.long;




type Glong_Array is array (Natural range <>) of Glong;




type Gshort is new C.short;




type Gshort_Array is array (Natural range <>) of Gshort;




type Guchar is new C.unsigned_char;




type Guchar_Array is array (Natural range <>) of Guchar;




type Guchar_Array_Access is access Guchar_Array;




type Guint is new C.unsigned;




subtype Guint16 is Guint range Guint'First .. (2 ** 16 - 1);




subtype Guint32 is Guint range Guint'First .. (2 ** 32 - 1);




type Guint32_Array is array (Natural range <>) of Guint32;




subtype Guint8 is Guint range Guint'First .. (2 ** 8 - 1);




type Guint_Array is array (Natural range <>) of Guint;




type Gulong is new C.unsigned_long;




type Gulong_Array is array (Natural range <>) of Gulong;




type Gushort is new C.unsigned_short;




type Gushort_Array is array (Natural range <>) of Gushort;




type Long_Array is array (Natural range <>) of C.long;




type Short_Array is array (Natural range <>) of C.short;




type String_Ptr is access all String;




Subprograms

Conversion services


function To_Boolean_Array      
  (A                  : in     Gboolean_Array)
   return Boolean_Array;

Convert a C-style boolean array into an Ada-style array.


function To_Boolean            
  (Value              : in     Gboolean)
   return Boolean;

Convert a C boolean into an Ada boolean.


function To_Boolean            
  (Value              : in     Gint)
   return Boolean;

Convert a C int into an Ada boolean.


function To_Boolean            
  (Value              : in     Guint)
   return Boolean;

Convert a C uint into an Ada boolean.


function To_Gboolean           
  (Bool               : in     Boolean)
   return Gboolean;

Convert an Ada boolean into a C boolean.


function To_Gint               
  (Bool               : in     Boolean)
   return Gint;

Convert an Ada boolean into a C int.


Quarks


function Quark_From_String     
  (Id                 : in     String)
   return GQuark;

Return, or create the quark associated with the string.
Note that if the quark does not already exist, an entry is created for it in the global htable for quarks.


function Quark_Try_String      
  (Id                 : in     String)
   return GQuark;

Return the quark associated with the string, if it exists.
If it does not exist, return Unknown_Quark.
