SYNOPSIS

10
11               my $p = Prima::Dialog::ColorDialog-> create(
12                       quality => 1,
13               );
14               printf "color: %06x", $p-> value if $p-> execute == mb::OK;

DESCRIPTION

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

Prima::Dialog::ColorDialog

24   Properties
25       quality BOOLEAN
26           Used to increase visual quality of the dialog if run on paletted
27           displays.
28
29           Default value: 0
30
31       value COLOR
32           Selects the color, represented by the color wheel and other dialog
33           controls.
34
35           Default value: "cl::White"
36
37   Methods
38       hsv2rgb HUE, SATURATION, LUMINOSITY
39           Converts color from HSV to RGB format and returns three integer
40           values, red, green, and blue components.
41
42       rgb2hsv RED, GREEN, BLUE
43           Converts color from RGB to HSV format and returns three numerical
44           values, hue, saturation, and luminosity components.
45
46       xy2hs X, Y, RADIUS
47           Maps X and Y coordinate values onto a color wheel with RADIUS in
48           pixels.  The code uses RADIUS = 119 for mouse position coordinate
49           mapping.  Returns three values, - hue, saturation and error flag.
50           If error flag is set, the conversion has failed.
51
52       hs2xy HUE, SATURATION
53           Maps hue and saturation onto 256-pixel wide color wheel, and
54           returns X and Y coordinates of the corresponding point.
55
56       create_wheel SHADES, BACK_COLOR
57           Creates a color wheel with number of SHADES given, drawn on a
58           BACK_COLOR background, and returns a "Prima::DeviceBitmap" object.
59
60       create_wheel_shape SHADES
61           Creates a circular 1-bit mask, with radius derived from SHAPES.
62           SHAPES must be same as passed to create_wheel.  Returns
63           "Prima::Image" object.
64

76                   Ctrl+Alt         disabledColor
77                   Ctrl+Alt+Shift   disabledBackColor

85
86       EndDragColor $PROPERTY, $WIDGET
87           Called when the user releases the mouse drag over a Prima widget.
88           Default action sets "$WIDGET->$PROPERTY" to the current color
89           value.
