NAME

       Curses::UI::Color - Color support module

WARNING

       This is a development version. As I do not expect to change the interface during this time it may happen
       that the color behaviour (e.g. to what extend color is drawn in a window) may change or even the colors
       themselves. If you want something stable, use -color_support => 0 , but you won't get those fency colors
       then :-)

DESCRIPTION

       This module provides all functions related to color support in Curses::UI. The color support was
       implemented without disturbing old applications, they will look as they used to do. Only if you enable
       color support explicitly and it is available on your terminal the color functions will have an effect.

SYNOPSIS

       my $cui = new Curses::UI(-color_support => 1,
                                -clear_on_exit => 0);

       my $mainw = $cui->add('screen', 'Window');

       $mainw->add('l','Label', -bg => "white",
                                -fg => "blue",
                                -text => "Colored Label");

METHODS

       •   new (-default-colors => BOOLEAN)

           Creates a new Curses::UI::Color object, the option default colors define if the use_default_colors
           function of Curses is used. See Curses for that.

       •   get_colors ( )

           Returns all in this object defined colors as an array

       •   colors ( )

           Is true if color support is enabled.

       •   define_color ( NAME, R, G, B )

           This function defines a new color in the Color object. The RGB values can be between 0 and 1000.
           Existing colors can be redefined.

USAGE

       Curses::UI has 7 predefined colors:
                black
                red
                green
                yellow
                blue
                magenta
                cyan
                white

       Curses::UI with color support also defines some new options:

            -fg  -bg for general foreground and background color.
           -tfg -tbg for widget title fg and bg color
           -bfg -bbg for widget border fg and bg color
           -sfg -sbg for scrollbar fg and bg color

       Every widget has has a runtime setter:
           set_color_fg ( COLOR )
           set_colof_bg ( COLOR )
           set_color_tfg ( COLOR )
           set_colof_tbg ( COLOR )
           set_color_bfg ( COLOR )
           set_colof_bbg ( COLOR )
           set_color_sfg ( COLOR )
           set_colof_sbg ( COLOR )

       Mostly every widget has a -fg and -bg option to set the foreground and background color using the above
       color names. Own colors can be defined using the define_color method. Every widget that supports color by
       now has also two functions set_color_fg and set_color_bg to set or change the color at runtime.  Widgets
       with borders and scrollbars can use -bfg and -bbg to set the foreground and background color of the
       border or the -sfg and -sbg option to set the colors of the scrollbar.  Widgets with titles can set the
       -tfg and -tbg option to define the title foreground and background color.

       Check also the examples/color_editor for seeing what is possible at the moment.
