Graphene.Size

Description

A size.

Equal

function Equal
   (Self : not null access Graphene_Size_T;
    B    : not null access Graphene_Size_T) return Boolean

Checks whether the two give Graphene.Size.Graphene_Size_T are equal. Since: gtk+ 1.0

Parameters

Self

B

a Graphene.Size.Graphene_Size_T

Return Value

true if the sizes are equal

Free

procedure Free (Self : not null access Graphene_Size_T)

Frees the resources allocated by graphene_size_alloc. Since: gtk+ 1.0

Parameters

Self

From_Object_Free

function From_Object_Free
  (B : not null access Graphene_Size_T) return Graphene_Size_T

Return the underlying object and free the pointer. This is meant to be used internally by GtkAda, and should not in general be called by user code.

Parameters

B

Return Value

Get_Type

function Get_Type return Glib.GType

Return Value

Graphene_Size_T

type Graphene_Size_T is record
   Width : Interfaces.C.C_float;
   Height : Interfaces.C.C_float;
end record;

A size.

Init

function Init
   (Self   : not null access Graphene_Size_T;
    Width  : Interfaces.C.C_float;
    Height : Interfaces.C.C_float) return access Graphene_Size_T

Initializes a Graphene.Size.Graphene_Size_T using the given Width and Height. Since: gtk+ 1.0

Parameters

Self

Width

the width

Height

the height

Return Value

the initialized Graphene.Size.Graphene_Size_T

Init_From_Size

function Init_From_Size
   (Self : not null access Graphene_Size_T;
    Src  : not null access Graphene_Size_T) return access Graphene_Size_T

Initializes a Graphene.Size.Graphene_Size_T using the width and height of the given Src. Since: gtk+ 1.0

Parameters

Self

Src

a Graphene.Size.Graphene_Size_T

Return Value

the initialized Graphene.Size.Graphene_Size_T

Interpolate

procedure Interpolate
   (Self   : not null access Graphene_Size_T;
    B      : not null access Graphene_Size_T;
    Factor : Gdouble;
    Res    : not null access Graphene_Size_T)

Linearly interpolates the two given Graphene.Size.Graphene_Size_T using the given interpolation Factor. Since: gtk+ 1.0

Parameters

Self

B

a Graphene.Size.Graphene_Size_T

Factor

the linear interpolation factor

Res

return location for the interpolated size

Scale

procedure Scale
   (Self   : not null access Graphene_Size_T;
    Factor : Interfaces.C.C_float;
    Res    : not null access Graphene_Size_T)

Scales the components of a Graphene.Size.Graphene_Size_T using the given Factor. Since: gtk+ 1.0

Parameters

Self

Factor

the scaling factor

Res

return location for the scaled size

Zero

function Zero return access constant Graphene_Size_T

A constant pointer to a zero Graphene.Size.Graphene_Size_T, useful for equality checks and interpolations. Since: gtk+ 1.0

Return Value

a constant size
