       Prima::ColorDialog - standard color selection facilities


               use Prima qw(StdDlg Application);

               my $p = Prima::ColorDialog-> create(
                       quality => 1,
               printf "color: %06x", $p-> value if $p-> execute == mb::OK;


       The module contains two packages, "Prima::ColorDialog" and
       "Prima::ColorComboBox", used as standard tools for interactive color
       selection. "Prima::ColorComboBox" is a modified combo widget, which
       provides selecting from predefined palette but also can invoke
       "Prima::ColorDialog" window.


       quality BOOLEAN
           Used to increase visual quality of the dialog if run on paletted

           Default value: 0

       value COLOR
           Selects the color, represented by the color wheel and other dialog

           Default value: "cl::White"

           Converts color from HSV to RGB format and returns three integer
           values, red, green, and blue components.

       rgb2hsv RED, GREEN, BLUE
           Converts color from RGB to HSV format and returns three numerical
           values, hue, saturation, and luminosity components.

       rgb2value RED, GREEN, BLUE
           Combines separate channels into single 24-bit RGB value and returns
           the result.

       value2rgb COLOR
           Splits 24-bit RGB value into three channels, red, green, and blue
           and returns three integer values.

       xy2hs X, Y, RADIUS
           Maps X and Y coordinate values onto a color wheel with RADIUS in
           pixels.  The code uses RADIUS = 119 for mouse position coordinate
           mapping.  Returns three values, - hue, saturation and error flag.
           If error flag is set, the conversion has failed.

       hs2xy HUE, SATURATION
           Maps hue and saturation onto 256-pixel wide color wheel, and
           returns X and Y coordinates of the corresponding point.

       create_wheel SHADES, BACK_COLOR
           Creates a color wheel with number of SHADES given, drawn on a
           BACK_COLOR background, and returns a "Prima::DeviceBitmap" object.

       create_wheel_shape SHADES
           Creates a circular 1-bit mask, with radius derived from SHAPES.
           SHAPES must be same as passed to create_wheel.  Returns
           "Prima::Image" object.

       BeginDragColor $PROPERTY
           Called when the user starts dragginh a color from the color wheel
           by with left mouse button and combination of Alt, Ctrl, and Shift
           keys. $PROPERTY is one of "Prima::Widget" color properties, and
           depends on combination of keys:

                   Alt              backColor
                   Ctrl             color
                   Alt+Shift        hiliteBackColor
                   Ctrl+Shift       hiliteColor
                   Ctrl+Alt         disabledColor
                   Ctrl+Alt+Shift   disabledBackColor

           Default action reflects the property to be changes in the dialog

           The notification is called when the value property is changed,
           either interactively or as a result of direct call.

       EndDragColor $PROPERTY, $WIDGET
           Called when the user releases the mouse drag over a Prima widget.
           Default action sets "$WIDGET->$PROPERTY" to the current color

           Contains cached result of create_wheel call.

           Contains cached result of create_wheel_shape call.


       Colorify INDEX, COLOR_PTR
           "nt::Action" callback, designed to map combo palette index into a
           RGB color.  INDEX is an integer from 0 to colors - 1, COLOR_PTR is
           a reference to a result scalar, where the notification is expected
           to write the resulting color.

       colors INTEGER
           Defines amount of colors in the fixed palette of the combo box.

       value COLOR
           Contains the color selection as 24-bit integer value.
