Detailed Description

Wrapper for colors.

The class is used for 2 purposes:

• Implicit converter for parameters. A function taking a Color as parameter can be given an sf::Color, RGB values or even a serialized string as argument.
• Storing no color at all. Some colors may be optionally set and can thus remain unspecified.

Constructor & Destructor Documentation

Color() [1/5]

TGUI_CONSTEXPR tgui::Color::Color ( )

inline

Creates the object without a color.

The isSet() function will return false when the object was created using this constructor.

Color() [2/5]

TGUI_CONSTEXPR tgui::Color::Color ( const sf::Color &  color )

inline

Creates the object from an sf::Color.

Parameters

color

Color to set

Color() [3/5]

TGUI_CONSTEXPR tgui::Color::Color ( std::uint8_t  red, std::uint8_t  green, std::uint8_t  blue, std::uint8_t  alpha = 255  )

inline

Creates the object from an the RGB or RGBA values.

Parameters

red	Red component
green	Green component
blue	Blue component
alpha	Alpha component

Color() [4/5]

tgui::Color::Color ( const String &  string )

inline

Creates the object from a string.

Parameters

string

String to be deserialized as color

The Deserializer class is used to convert the string into a color.

Color() [5/5]

tgui::Color::Color ( const char *  string )

inline

Creates the object from a string.

Parameters

string

String to be deserialized as color

The Deserializer class is used to convert the string into a color.

Member Function Documentation

getAlpha()

TGUI_CONSTEXPR std::uint8_t tgui::Color::getAlpha ( ) const

inline

Returns the alpha component of the color.

Returns

Alpha component of the stored color or the one from the default color is no color was set

getBlue()

TGUI_CONSTEXPR std::uint8_t tgui::Color::getBlue ( ) const

inline

Returns the blue component of the color.

Returns

Blue component of the stored color or the one from the default color is no color was set

getGreen()

TGUI_CONSTEXPR std::uint8_t tgui::Color::getGreen ( ) const

inline

Returns the green component of the color.

Returns

Green component of the stored color or the one from the default color is no color was set

getRed()

TGUI_CONSTEXPR std::uint8_t tgui::Color::getRed ( ) const

inline

Returns the red component of the color.

Returns

Red component of the stored color or the one from the default color is no color was set

isSet()

TGUI_CONSTEXPR bool tgui::Color::isSet ( ) const

inline

Checks if a color was set.

Returns

True if a color was passed to the constructor, false when the default constructor was used

operator sf::Color()

tgui::Color::operator sf::Color ( ) const

inline

Converts this object into an sf::Color object.

Returns

The color stored in this object, or the default color if no color was set

operator Vertex::Color()

tgui::Color::operator Vertex::Color ( ) const

inlineexplicit

Converts this object into a Vertex::Color object.

Returns

The color stored in this object, or the default color if no color was set
