◆ 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]
◆ 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().
◆ wrap() [1/2]
- Parameters
-
- Returns
- A C++ instance that wraps this C instance.
◆ wrap() [2/2]
- Parameters
-
- Returns
- A C++ instance that wraps this C instance.
◆ gobject_
| PangoColor Pango::Color::gobject_ |
