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.

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.

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.

const PangoColor* Pango::Color::gobj | ( |  | ) | const`[inline]`

| Provides access to the underlying C instance.

PangoColor* Pango::Color::gobj | ( |  | ) | `[inline]`

| Provides access to the underlying C instance.

Pango::Color::operator bool | ( |  | ) |

| Tests whether the Color is valid.

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.

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.

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.

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.
