| Additionally, macros can be used to specify colors where levels of opacity (or, thought of the other way, transparency) are desired. An additional pair of bytes is appended to the RGB color value, which corresponds to the COLOR NL field in the Widget file. Values of zero (hex 00) through 255 (hex FF) are valid for opacity, but 00 and 01 retain their original purpose and values - 00 makes a widget completely transparent, while 01 or FF makes it completely opaque. For example, specifying a color as #FF0000FF or #FF000001 would be solid red, while #FF000000 would be fully transparent and therefore invisible; #FF000088 would provide 50% transparency to the widget.
To use these in Widget Properties, set the appropriate macro below to the hex value desired in the Tooltip field (e.g., @SFC=#005872A4) |
