Re: Turning a LyX environment into a LaTeX command

Hi all,
After Richard Heck talked about LatexType=Command in the LyX Title environment 
thread, I started experimenting and got it to work. I have a LyX and LaTeX 
breakout environment (breakout is the name of the environment) which prints 
in a shaded box, with a label. However, the label isn't hard coded, but 
instead is contained in a variable called breakoutstring.

I had previously been setting breakoutstring with ERT before the section of 
breakout environment, but I don't like ERT. So, taking Richard Heck's advice, 
I made a BreakoutTitle LyX environment whose LatexType is command, and whose 
LatexName is setBreakoutstring. setBreakoutstring is simply a LaTeX (actually 
TeX) command to set the variable breakoutstring:

\def\setBreakoutstring#1{\def\breakoutstring{#1}}

I tried first to do it with \newcommand, but couldn't get it to compile. If 
anyone can show me how, please do.

Anyway, the following is the code for BreakoutTitle:

# Breakout title style definition
Style BreakoutTitle
  Margin                Static
  LatexType             Command
  InTitle               1
  LatexName             setBreakoutstring
  ParSkip               0.4
  ItemSep               0
  TopSep                1
  BottomSep             0.0
  ParSep                1
  Align                 Center
  AlignPossible         Center
  LabelType             No_Label

  # standard font definition
  Font 
    Size		Large
  EndFont

Preamble
        \def\setBreakoutstring#1{\def\breakoutstring{#1}}
EndPreamble

End



And in case anyone wants to see it, here's the code for Breakout:


# ### Labeled shadowed box for Breakouts ###
Style Breakout
  LatexType             Environment
  LatexName             breakout_l
  
  AlignPossible         Left
  LeftMargin            "MMMMM"
  RightMargin           "MMMMM"
  ParSkip               0.7
  ParSep                0.7
  TopSep                0.7
  BottomSep             0.7

  Font
  EndFont
  Preamble
    \newenvironment{breakout_l}{\begin{shadowbox}{\breakoutstring}}
{\end{shadowbox}}%
  EndPreamble
End


In the preceding, shadowbox is just a home grown LaTeX environment to put the 
text in shading, and bring its borders in.

Obviously, now that I've done this, doing subtitles with an environment 
instead of ERT is pretty easy. Hope some of you can use this.

Richard -- thanks for the tip. I've been trying to do this since 2001.

Thanks

Steve,

Thanks for sharing this.  I'll beat Christian to the punch :-) and 
suggest putting on the wiki as a tip.
