Constructor & Destructor Documentation

Color() [1/5]

sf::xgl::Color::Color

(

)

Default constructor initializing with a black color.

Color() [2/5]

sf::xgl::Color::Color ( const QColor &  color )

explicit

Constructor for Qt QColor.

Color() [3/5]

sf::xgl::Color::Color ( const QColor &  color, float  alpha  )

explicit

Constructor for Qt QColor with a different alpha value.

Color() [4/5]

sf::xgl::Color::Color	(	const Color &	color,
		GLfloat	alpha
	)

Initializing constructor copying a color but setting a different alpha value.

Parameters

color	Copy color.
alpha	Alpha transparency value between 0 and 1 where 0 is fully transparent.

Color() [5/5]

sf::xgl::Color::Color	(	float	r,
		float	g,
		float	b,
		float	a = 1.0f
	)

Initializing constructor for separate rgba values.

Parameters

r	Red value between 0 and 1.
g	Green value between 0 and 1.
b	Blue value between 0 and 1.
a	Alpha transparency value between 0 and 1 where 0 is fully transparent.
