General ⇒ Customized "headings" Page Style

[franzrogar]

Hello,

I'm writting my custom class but I've found a problem I've not been able to solve. When I add the hrule, it's missplaced: instead of using baseline (to keep distance from headings) it uses descenders line. (Yes, I'm spaniard... sorry). I'll try to explain it:

- If text has "g" or "p" or other letter with descenders, headings are at ~ 6pt.
- If text has no descenders, headings are at ~ 4pt.

So you can see that hrule is moving if you compare differentes pages.

This' the code:

Code: Select all

\if@twoside
  \def\ps@headings{%
      \let\@oddfoot\@empty\let\@evenfoot\@empty
      \def\@evenhead{\vbox{{\small\lsc\thepage}\normalfont\hfil\leftmark \vskip 5\p@ \hrule}}%
      \def\@oddhead{\vbox{\normalfont\partmark\hfil{\small\thepage} \vskip 5\p@ \hrule}}%

Anyone has any idea how could I solve this?

Thanks in advance

Since \hrule is affected by the depth of the preceding text, an alternative strategy could be to write first the rule at a fixed length below the baseline. Let \HeadRule defined as follows:

Code: Select all

\newcommand{\HeadRule}{\makebox[0pt][l]{\rule[-5pt]{\textwidth}{0.4pt}}}

Just to compare it with \hrule, try this in the body of the document:

Code: Select all

\parindent 0pt
\HeadRule Height and depth\par
\HeadRule Text and boxes\par
Height and depth \vskip 5pt\hrule\par
Text and boxes \vskip 5pt \hrule\par

With the help of \HeadRule, the definition of \@evenhead, for example, could be:

Code: Select all

\def\@evenhead{\HeadRule{\small\lsc\thepage}\normalfont\hfil\leftmark}

By the way, since you are a Spanish-speaking user of TeX, I would suggest you to join the es-tex list, which, like this community, is quite active and helpful.

Thank you very much Juanjo, that gave me the solution and reach what I wanted:

Code: Select all

\if@twoside
  \def\ps@headings{%
      \let\@oddfoot\@empty\let\@evenfoot\@empty
      \def\@evenhead{\vbox{\hbox to \textwidth{\rule[-.5ex]{0em}{.5ex}
          \rm {\small\thepage}\hfil \sl \leftmark}
          \vskip3pt \hrule height.3pt}}
      \def\@oddhead{\vbox{\hbox to \textwidth{\rule[-.5ex]{0em}{.5em}
          \sl \partmark \hfil \rm{\small\thepage}} 
          \vskip3pt \hrule height.3pt}}
