distance between threads

[GoogleCodeExporter]

define the edge distance for threads too and not only for instances.

This would be great to have! :)

my workaround was this

\begin{sequencediagram}
\newthread{P1}{P1}
\tikzstyle{inststyle}+=[below right=-0.85cm and 2cm of P1]
\newthread{P2}{P2}
\tikzstyle{inststyle}+=[below right=-0.85cm and 2cm of P2]
\newthread{P3}{P3}
\end{sequencediagram}

which works, but isn't that great.

for everyone else wondering about Unknown operator `a' or `an' errors: also add \usetikzlibrary{positioning} to your document

% new an instance thread
% Example:
% \newthread[edge distance]{var}{thread name}
\newcommand{\newthread}[3][0.2]{
  \newinst[#1]{#2}{#3}
  \stepcounter{threadnum}
  \node[below of=inst\theinstnum,node distance=0.8cm] (thread\thethreadnum) {};
  \tikzstyle{threadcolor\thethreadnum}=[fill=gray!30]
  \tikzstyle{instcolor#2}=[fill=gray!30]
}

Derived from this I've also added a color option:

% new command for adding a distance option for threads as well
% \newthread[color][distance]{id}{title}
\RequirePackage{xargs}
\renewcommandx{\newthread}[4][1=gray!30, 2=0.2]{
  \newinst[#2]{#3}{#4}
  \stepcounter{threadnum}
  \node[below of=inst\theinstnum,node distance=0.8cm] (thread\thethreadnum) {};
  \tikzstyle{threadcolor\thethreadnum}=[fill=#1]
  \tikzstyle{instcolor#3}=[fill=#1]
}

I'm also wondering why this isn't possible yet

[yegor256]

would be great to have it!

Surely, it seems quite essential.
