value = %U_WINCOLOR(subfunction[, arg, ...])
or
xcall U_WINCOLOR(subfunction[, arg, ...])
Return value
value
On Windows, a value specific the to subfunction. On Unix, always returns false. On OpenVMS, always returns true. (^VAL)
Arguments
subfunction
The operation to perform: (n)
Display the Color dialog box with an initial color selection.
Return RGB values associated with Synergy colors.
Return the RGB value for Toolkit hyperlink prompts.
Return the foreground and background colors (as RGB values) for a Synergy palette entry.
Use an RGB value to set a Synergy color.
arg
(optional) One or more arguments if required for subfunction.
Discussion
%U_WINCOLOR performs Windows-specific color operations. See the individual subfunctions for details.
If a value other than one of those listed above is passed for subfunction, a fatal Toolkit error will occur.
value = %U_WINCOLOR(D_CHOOSECOLOR, color, [help_filename][, help_context_id])
Return value
value
On Windows, the user selected color, or the color passed as color if the user cancels. (^VAL)
Arguments
color
The color (RGB value) you want initially selected when the Color dialog box opens. (n)
help_filename
(optional) The name of the help file. (a)
help_context_id
(optional) The context identifier for help. Required if help_filename is passed. (n)
Discussion
The D_CHOOSECOLOR subfunction of %U_WINCOLOR displays the Color dialog box with an initially selected color (color). This function returns either the color selected by the user or, if the user cancels, the color specified by color. See the GetCellColor Discussion for information on RGB values.
If help_filename is passed, the dialog will have a Help button. Help_filename can be the name of either a WinHelp file (.hlp) or an HTML Help file (.chm):
- If the file extension is .hlp, help_context_id is passed as a context number to the HELP_CONTEXT command for the WinHelp API. See the Microsoft documentation for WinHelp for more information on this command.
- If the file extension is .chm, the HtmlHelp API is used, and help_context_id is passed on to the HTML Help API command HH_HELP_CONTEXT. See the Microsoft documentation for the HTML Help API for more information on this command.
Examples
The following example displays a dialog box with the initial value specified by color (i4) and returns the color chosen by the user (if any) in new_color (i4).
new_color = %u_wincolor(D_CHOOSECOLOR, color)
The next example includes a help button on the dialog box.
new_color = %u_wincolor(D_CHOOSECOLOR, color, "helpfile.hlp", select_color_id)
value = %U_WINCOLOR(D_GETCOLORS, color_array, [start][, end])
or
xcall U_WINCOLOR(D_GETCOLORS, color_array, [start][, end])
Return value
value
On Windows, true. (^VAL)
Arguments
color_array
The first element in an array of returned RGB values for Synergy colors. If this array is not large enough to store all the returned colors, a fatal error may result (though results are unpredictable). (n)
start
(optional) The index of the first color to return (0 through 511). A value less than 0 or greater than 511 will cause a fatal runtime error. (n)
end
(optional) The index of the last color to return (0 through 511). A value less than 0 or greater than 511 will cause a fatao runtime error. If the value is less than start, no colors (or error) will be returned. (n)
Discussion
The D_GETCOLORS subfunction of %U_WINCOLOR returns an array filled with the RGB values for a range of Synergy colors. D_GETCOLORS gets this information from the current color definitions. These can be the memory-resident defaults, colors defined in synergy.ini or synuser.ini, or colors set with D_SETCOLOR.
Start and end values correspond to numbers for Synergy colors. For example, of you pass 1 as start, the first element in the array will be the value for Synergy color 1. If you don’t pass start, the array index will be one higher than the accessed color. Element 1 will contain Synergy color 0, element 2 will contain Synergy color 1, and so forth. This is because Synergy DBL arrays start with element 1, but Synergy colors start with color 0.
Here’s how start and end work:
- If you don’t pass start or end, D_GETCOLOR returns a 256 element array whose first element is Synergy color 0 and whose final element is Synergy color 255.
- If you don’t pass start, but do pass end, D_GETCOLOR returns an array whose first element is Synergy color 0 and whose last element is specified by end. (The number of elements in the array will be end plus 1.)
- If you don’t pass end, but do pass start, D_GETCOLOR returns an array whose first element is determined by start and whose final element is Synergy color 255.

Examples
The following example returns in color_array (256i4) the RGB values for Synergy colors 0 through 255:
success = %u_wincolor(D_GETCOLORS, color_array)
The next example returns in win_sys_colors (256i4) the RGB values for Synergy colors 256 through 511:
success = %u_wincolor(D_GETCOLORS, win_sys_colors, 256, 511)
value = %U_WINCOLOR(D_HYPER_FG)
Return value
value
On Windows, the color of Toolkit hyperlink prompts as an RGB value. (^VAL)
Discussion
The D_HYPER_FG subfunction of %U_WINCOLOR returns the color of Toolkit hyperlink prompts as an RGB value. See the GetCellColor Discussion for information on RGB values. (n)
Examples
The following example returns in hyper_color (i4) the RGB value associated with a Toolkit hyperlink prompt.
hyper_color = %u_wincolor(D_HYPER_FG)
value = %U_WINCOLOR(D_PALETTE_RGB, palette, fg_color, bg_color[, attr])
or
xcall U_WINCOLOR(D_PALETTE_RGB, palette, fg_color, bg_color[, attr])
Return value
value
On Windows, true if successful, or false if not. (^VAL)
Arguments
palette
A Synergy palette entry number (1-16). (n)
fg_color
The returned foreground color (RGB value). (n)
bg_color
The returned background color (RGB value). (n)
attr
Optional attribute to apply. You can supply only one attr argument, but its value can be composed by adding together the defined literals in tools.def or by using the supplied combination definitions (for example, A_HR for highlight and reverse). (n)
Discussion
The D_PALETTE_RGB subfunction of %U_WINCOLOR returns the foreground and background colors associated with a Synergy palette entry as RGB values. (See the GetCellColor Discussion for information on RGB values.) If attr is passed, the specified attribute (A_* in tools.def) are applied before evaluating the colors. (See the Attribute Flag Definitions table.)

Examples
This example returns the foreground and background colors associated with Synergy palette entry 6.
success = %u_wincolor(D_PALETTE_RGB, 6, fg_color, bg_color)
value = %U_WINCOLOR(D_SETCOLOR, color, rgb)
or
xcall U_WINCOLOR(D_SETCOLOR, color, rgb)
Return value
value
On Windows, true if successful, or false if not (for example, if color is invalid). (^VAL)
Arguments
color
A Synergy color (0-255). A value less than 0 or greater than 255 will cause a fatal runtime error. (n)
rgb
An RGB value. (n)
Discussion
The D_SETCOLOR subfunction of %U_WINCOLOR sets a Synergy color (specified by color) to the RGB value represented by the value passed rgb.
D_SETCOLOR settings override color settings in synergy.ini and synuser.ini, as well as memory-resident defaults. But D_SETCOLOR settings last only until the program is exited. (Use the %U_SAVELOG function if you wish to save this new color to the [colors] section of synergy.ini or synuser.ini.)

The following example sets Synergy color 77 to the RGB value specified in color (i4).
success = %u_wincolor(D_SETCOLOR, 77, color)
