Implement Underline property in RunFormat

[y0ung3r]

RunFormat does not support Underline at this time. Let's add the ability to set this property.

Documentation

u specifies that the content should be displayed with an underline: <w:u w:val="double"/>.

• color - specifies the color for the underlining. Values are given as hex values (in RRGGBB format). No #, unlike hex values in HTML/CSS. E.g., color="FFFF00". A value of auto is also permitted and will allow the consuming word processor to determine the color based on the context.

• val - Specifies the pattern to be used to create the underline. Possible values are:

  • dash - a dashed line
  • dashDotDotHeavy - a series of thick dash, dot, dot characters
  • dashDotHeavy - a series of thick dash, dot characters
  • dashedHeavy - a series of thick dashes
  • dashLong - a series of long dashed characters
  • dashLongHeavy - a series of thick, long, dashed characters
  • dotDash - a series of dash, dot characters
  • dotDotDash - a series of dash, dot, dot characters
  • dotted - a series of dot characters
  • dottedHeavy - a series of thick dot characters
  • double - two lines
  • none - no underline
  • single - a single line
  • thick - a single think line
  • wave - a single wavy line
  • wavyDouble - a pair of wavy lines
  • wavyHeavy - a single thick wavy line
  • words - a single line beneath all non-space characters
