"""DetailsViewer class. This class implements a pure input window which allows you to meticulouslyedit the current color.  You have both mouse control of the color (via thebuttons along the bottom row), and there are keyboard bindings for each of theincrement/decrement buttons. The top three check buttons allow you to specify which of the three colorvariations are tied together when incrementing and decrementing.  Red, green,and blue are self evident.  By tying together red and green, you can modifythe yellow level of the color.  By tying together red and blue, you can modifythe magenta level of the color.  By tying together green and blue, you canmodify the cyan level, and by tying all three together, you can modify thegrey level. The behavior at the boundaries (0 and 255) are defined by the `At boundary'option menu:     Stop        When the increment or decrement would send any of the tied variations        out of bounds, the entire delta is discarded.     Wrap Around        When the increment or decrement would send any of the tied variations        out of bounds, the out of bounds variation is wrapped around to the        other side.  Thus if red were at 238 and 25 were added to it, red        would have the value 7.     Preseve Distance        When the increment or decrement would send any of the tied variations        out of bounds, all tied variations are wrapped as one, so as to        preserve the distance between them.  Thus if green and blue were tied,        and green was at 238 while blue was at 223, and an increment of 25        were applied, green would be at 15 and blue would be at 0.     Squash        When the increment or decrement would send any of the tied variations        out of bounds, the out of bounds variation is set to the ceiling of        255 or floor of 0, as appropriate.  In this way, all tied variations        are squashed to one edge or the other. The following key bindings can be used as accelerators.  Note that Pynche canfall behind if you hold the key down as a key repeat: Left arrow == -1Right arrow == +1 Control + Left == -10Control + Right == 10 Shift + Left == -25Shift + Right == +25""" from Tkinter import * STOP = 'Stop'WRAP = 'Wrap Around'RATIO = 'Preserve Distance'GRAV = 'Squash' ADDTOVIEW = 'Details Window...' class DetailsViewer:    def __init__(self, switchboard, master=None):        self.__sb = switchboard        optiondb = switchboard.optiondb()        self.__red, self.__green, self.__blue = switchboard.current_rgb()        #
