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. + \ No newline at end of file -- cgit v1.2.3
