Description

+ +The Fl_Color_Chooser widget provides a standard RGB color +chooser. You can place any number of these into a panel of your own +design. This widget contains the hue box, value slider, and rgb input +fields from the above diagram (it does not have the color chips or the +Cancel or OK buttons). The callback is done every time the user +changes the rgb value. It is not done if they move the hue control in +a way that produces the same rgb value, such as when saturation +or value is zero. + +

Methods

+ + + +

Fl_Color_Chooser::Fl_Color_Chooser(int x, int y, int w, int h, const char *label = 0)

+ +Creates a new Fl_Color_Chooser widget using the given +position, size, and label string. The recommended dimensions are +200x95. The color is initialized to black. + +

virtual Fl_Color_Chooser::~Fl_Color_Chooser()

+ +The destructor removes the color chooser and all of its controls. + +

double Fl_Color_Chooser::hue() const

+ +Return the current hue. 0 <= hue < 6. Zero is red, one is +yellow, two is green, etc. This value is convienent for the internal +calculations - some other systems consider hue to run from zero to +one, or from 0 to 360. + +

double Fl_Color_Chooser::saturation() const

+ +Returns the saturation. 0 <= saturation <= 1. + +

double Fl_Color_Chooser::value() const

+ +Returns the value/brightness. 0 <= value <= 1. + +

double Fl_Color_Chooser::r() const

+ +Returns the current red value. 0 <= r <= 1. + +

double Fl_Color_Chooser::g() const

+ +Returns the current green value. 0 <= g <= 1. + +

double Fl_Color_Chooser::b() const

+ +Returns the current blue value. 0 <= b <= 1. + +

int Fl_Color_Chooser::rgb(double, double, +double)

+ +Sets the current rgb color values. Does not do the callback. Does +not clamp (but out of range values will produce psychedelic effects in +the hue selector). + +

int Fl_Color_Chooser::hsv(double,double,double)

+ +Set the hsv values. The passed values are clamped (or for hue, +modulus 6 is used) to get legal values. Does not do the callback. + +

static void Fl_Color_Chooser::hsv2rgb(double, double, +double, double&, double&, double&)

+ +This static method converts HSV colors to RGB colorspace. + +

static void Fl_Color_Chooser::rgb2hsv(double, double, double, double&, +double&, double&)

+ +This static method converts RGB colors to HSV colorspace. + + + -- cgit v1.2.3
