Member Function Documentation

get_blue()

guint16 Pango::Color::get_blue

(

)

const

Gets the blue component of the color.

Returns

The blue component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity.

get_green()

guint16 Pango::Color::get_green

(

)

const

Gets the green component of the color.

Returns

The green component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity.

get_red()

guint16 Pango::Color::get_red

(

)

const

Gets the red component of the color.

Returns

The red component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity.

get_type()

static GType Pango::Color::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

gobj() [1/2]

PangoColor * Pango::Color::gobj ( )

inline

Provides access to the underlying C instance.

gobj() [2/2]

const PangoColor * Pango::Color::gobj ( ) const

inline

Provides access to the underlying C instance.

operator bool() [1/2]

Pango::Color::operator bool ( )

explicit

Deprecated

Use the const version.

operator bool() [2/2]

Pango::Color::operator bool ( ) const

explicit

Tests whether the Color is valid.

operator=() [1/2]

Color & Pango::Color::operator= ( Color && other )

noexcept

operator=() [2/2]

Color & Pango::Color::operator= ( const Color & other )

noexcept

parse()

bool Pango::Color::parse

(

const Glib::ustring &

spec

)

Fill in the fields of a color from a string specification.

The string can either one of a large set of standard names. (Taken from the X11 <filename>rgb.txt</filename> file), or it can be a hex value in the form '#rgb' '#rrggbb' '#rrrgggbbb' or '#rrrrggggbbbb' where 'r', 'g' and 'b' are hex digits of the red, green, and blue components of the color, respectively. (White in the four forms is '#fff' '#ffffff' '#fffffffff' and '#ffffffffffff')

Parameters

spec	A string specifying the new color.

Returns

true if parsing of the specifier succeeded, otherwise false.

set_blue()

void Pango::Color::set_blue

(

const guint16 &

value

)

Sets the blue component of the color.

Parameters

value

The blue component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity.

set_green()

void Pango::Color::set_green

(

const guint16 &

value

)

Sets the green component of the color.

Parameters

value

The green component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity.

set_red()

void Pango::Color::set_red

(

const guint16 &

value

)

Sets the red component of the color.

Parameters

value

The red component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity.

to_string()

Glib::ustring Pango::Color::to_string

(

)

const

Returns a textual specification of color in the hexadecimal form #rrrrggggbbbb, where r, g and b are hex digits representing the red, green, and blue components respectively.

Since pangomm 1.16

Returns

A newly-allocated text string.
