## 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()

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.

The string is 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 that must be freed with Glib::free().

## Friends And Related Symbol Documentation

## ◆ wrap() [1/2]

const Pango::Color & wrap | ( | const PangoColor * | object | ) |
| related

Parameters

  object | The C instance

Returns
  A C++ instance that wraps this C instance.

## ◆ wrap() [2/2]

Pango::Color & wrap | ( | PangoColor * | object | ) |
| related

Parameters

  object | The C instance

Returns
  A C++ instance that wraps this C instance.
