A Gdk.RGBA.Gdk_RGBA is used to represent a (possibly translucent) color, in a way that is compatible with cairo's notion of color.
type array_of_Gdk_RGBA is array (Natural range <>) of Gdk_RGBA;
Black_RGBA : constant Gdk_RGBA := (0.0, 0.0, 0.0, 1.0);
function Copy (Self : Gdk_RGBA) return Gdk_RGBA
Makes a copy of a Gdk.RGBA.Gdk_RGBA. The result must be freed through Gdk.RGBA.Free. Since: gtk+ 3.0
A newly allocated Gdk.RGBA.Gdk_RGBA, with the same contents as Rgba
function Equal (Self : Gdk_RGBA; P2 : Gdk_RGBA) return Boolean
Compares two RGBA colors. Since: gtk+ 3.0
another Gdk.RGBA.Gdk_RGBA pointer
True if the two colors compare equal
procedure Free (Self : Gdk_RGBA)
Frees a Gdk.RGBA.Gdk_RGBA created with Gdk.RGBA.Copy Since: gtk+ 3.0
function From_Object_Free (B : access Gdk_RGBA) return Gdk_RGBA
A Gdk.RGBA.Gdk_RGBA is used to represent a (possibly translucent) color, in a way that is compatible with cairo's notion of color.
type Gdk_RGBA is record
Red : Gdouble;
Green : Gdouble;
Blue : Gdouble;
Alpha : Gdouble;
end record;
function Gdk_RGBA_Or_Null (Val : System.Address) return System.Address
Used for the GtkAda binding itself. Return either a Null_Address or a pointer to Val, depending on whether Val is the null value for the type. In all cases, Val is supposed to be an access to the type mentioned in the name of the subprogram. In Ada2012, these could be replaced with expression functions instead.
function Get_Property
(Object : access Glib.Object.GObject_Record'Class;
Name : Property_RGBA) return Gdk_RGBA
function Get_Type return Glib.GType
function Get_Value (Value : Glib.Values.GValue) return Gdk_RGBA
Conversion functions for storing a Gdk_RGBA as a GValue.
function Hash (Self : Gdk_RGBA) return Guint
A hash function suitable for using for a hash table that stores Gdk_RGBAs. Since: gtk+ 3.0
The hash value for P
Null_RGBA : constant Gdk_RGBA := (0.0, 0.0, 0.0, 0.0);
procedure Parse
(Self : out Gdk_RGBA;
Spec : UTF8_String;
Success : out Boolean)
Parses a textual representation of a color, filling in the Red, Green, Blue and Alpha fields of the Rgba Gdk.RGBA.Gdk_RGBA. The string can be either one of: - A standard name (Taken from the X11 rgb.txt file). - A hexadecimal value in the form "\rgb", "\rrggbb", "\rrrgggbbb" or "\rrrrggggbbbb" - A RGB color in the form "rgb(r,g,b)" (In this case the color will have full opacity) - A RGBA color in the form "rgba(r,g,b,a)" Where "r", "g", "b" and "a" are respectively the red, green, blue and alpha color values. In the last two cases, "r", "g", and "b" are either integers in the range 0 to 255 or percentage values in the range 0% to 100%, and a is a floating point value in the range 0 to 1. Since: gtk+ 3.0
the string specifying the color @return True if the parsing succeeded
type Property_RGBA is new Glib.Property;
procedure Set_Property
(Object : access Glib.Object.GObject_Record'Class;
Name : Property_RGBA;
Value : Gdk_RGBA)
procedure Set_Value (Value : in out Glib.Values.GValue; Val : Gdk_RGBA)
Conversion functions for storing a Gdk_RGBA as a GValue.
function To_String (Self : Gdk_RGBA) return UTF8_String
Returns a textual specification of Rgba in the form rgb(r,g,b) or rgba(r g,b,a), where "r", "g", "b" and "a" represent the red, green, blue and alpha values respectively. "r", "g", and "b" are represented as integers in the range 0 to 255, and "a" is represented as a floating point value in the range 0 to 1. These string forms are string forms that are supported by the CSS3 colors module, and can be parsed by Gdk.RGBA.Parse. Note that this string representation may lose some precision, since "r", "g" and "b" are represented as 8-bit integers. If this is a concern, you should use a different representation. Since: gtk+ 3.0
A newly allocated text string
