Attributes/text/smath/01/03091300.xhpSun Microsystems, Inc.attributes; additional informationAttributesAdditional information about attributes in $[officename] Math is found here.The acute, bar, breve, check, circle, dot, ddot, dddot, grave, hat, tilde and vec attributes always have a fixed size and do not become wider (longer) if they are above a long symbol. By default, the attributes are centered.The only attributes which grow with the length of the symbol are overline, underline and overstrike.For some character strings, it is possible that a line inserted with underline is too close to the character. In this case, an empty group can solve the problem: underline Q sub {} instead of underline Q.
