Fl_Group | +----Fl_Color_Chooser
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.
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.
The destructor removes the color chooser and all of its controls.
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.
Returns the saturation. 0 <= saturation <= 1.
Returns the value/brightness. 0 <= value <= 1.
Returns the current red value. 0 <= r <= 1.
Returns the current green value. 0 <= g <= 1.
Returns the current blue value. 0 <= b <= 1.
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).
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.
This static method converts HSV colors to RGB colorspace.
