       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 displays.

           Default value: 0

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

           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 title

           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 value.

           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.
