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.

PangoColor* Pango::Color::gobj | ( | ) | [inline] |
Pango::Color::operator bool | ( | ) | const |
Tests whether the Color is valid.
Pango::Color::operator bool | ( | ) |
- Deprecated:
- Use the const version.
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.
Glib::ustring Pango::Color::to_string | ( | ) | const |
Return value: a newly-allocated text string that must be freed with Glib::free().
- Returns:
- A newly-allocated text string that must be freed with Glib::free().
