Pango::Color::Color (  )
Pango::Color::Color ( const PangoColor *  gobject ) [explicit]

Member Function Documentation

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]

Provides access to the underlying C instance.

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

Provides access to the underlying C instance.

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:
specA 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:
valueThe 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:
valueThe 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:
valueThe 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

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 that must be freed with Glib::free().
