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.
Properties 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" Methods hsv2rgb HUE, SATURATION, LUMINOSITY 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. Events 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 Change 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. Variables $colorWheel Contains cached result of create_wheel call. $colorWheelShape Contains cached result of create_wheel_shape call.
Events 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. Properties 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.
