WoW:Using the ColorPickerFrame

What is it?

The ColorPickerFrame (See: XML_User_Interface#ColorSelect) is the default WoW frame to easily select color and opacity using a GUI. The ColorPickerFrame comes with customizable functions, which are next.

ColorPickerFrame functions

ColorPickerFrame.func();
--Called on changing the color wheel

ColorPickerFrame.opacityFunc();
--Called on changing the opacity slider

ColorPickerFrame.cancelFunc();
 --Called on hitting CANCEL button OR pressing ESCAPE

These functions can be specified by you to do something. The best example is setting some variables to the selected color as it changes. Check the following code:

ColorPickerFrame.func = MY_COLOR_FUNCTION

function MY_COLOR_FUNCTION()
  local R,G,B = ColorPickerFrame:GetColorRGB();
end

All the functions can be set in that manner.
