Question
How do you set all edges in an automaton to have the additional parameter double?
This should be easy, but I can't find the solution here or in the tikz/pgf manual or anywhere else.
double
should not be overwritten by independent parameters: edge[bend left]
with default double
should thus be equivalent to edge[bend left, double]
.
Details
Currently, I'm using the parameter everywhere:
\path[->]
(s0)+(-.5cm,.5cm) edge[bend right,double] (s0)
(s0) edge[bend left,double] node[pos=0.3] {$a$} (s1)
(s1) edge[bend left,double] node {$\epsilon,a$} (s0)
(s0) edge[loop above,double] node {$\epsilon,a$} (s0)
(s1) edge[loop below,double] node {$\epsilon,a$} (s1);
I tried \path[->,double]
and various combinations of \pgfset
and \tikzstyle
, but I just don't know how to get to set double
the edge's default parameter.
Best Answer
You can add different style keys by appending or prefixing. In this context we need to append the
double
key to eachedge
. Since this appending is local to the path it doesn't affect succesive edges.Note that
loop
only needs()
you don't need to fill the brackets.
