I'm trying to add a TikZ picture in my LyX document. To do this, I organize the TikZ tex code in Texmaker (a friend sent me a tikz code model in a .tex file) and then I copy it to a ERT in LyX (making sure to use the correct packages). The problem is that the code works in Texmaker when I export it to pdf, but doesn't work when I try to preview it with LyX! I get the error:
File ended while scanning use of \pgfkeys@@qset.
<*>newfile3.tex
*** (job aborted, no legal \end found)
The tex code that is working in Texmaker is the following:
\documentclass[12pt,a4paper]{article}
\usepackage{tikz}
\usetikzlibrary{calc}
\begin{document}
\tikzset{
% Two node styles for game trees: solid and hollow
solid node/.style={circle,draw,inner sep=1.5,fill=black},
hollow node/.style={circle,draw,inner sep=1.5}
}
\begin{center}
\begin{tikzpicture}[scale=1.5,font=\footnotesize]
% Specify spacing for each level of the tree
\tikzstyle{level 1}=[level distance=15mm,sibling distance=35mm]
\tikzstyle{level 2}=[level distance=15mm,sibling distance=15mm]
\tikzstyle{level 3}=[level distance=15mm,sibling distance=8mm]
% The Tree
\node(0)[hollow node,label=above:{Jogador 1},label=right:{$x''$}]{}
child{node(1)[solid node]{}
child{node(3)[solid node,label=right:{$x$}]{}
child{node[solid node,label=below:{$(a_1,b_1)$}]{} edge from parent node[left]{$C$}}
child{node[solid node,label=below:{$(a_2,b_2)$}]{} edge from parent node[right]{$D$}}
edge from parent node[left]{$L$}}
child{node(4)[solid node]{}
child{node[solid node,label=below:{$(a_3,b_3)$}]{} edge from parent node[left]{$C$}}
child{node[solid node,label=below:{$(a_4,b_4)$}]{} edge from parent node[right]{$D$}}
edge from parent node[left]{$R$}}edge from parent node[left,xshift=-3]{$A$}
}
child{node(2)[solid node]{}
child{node(5)[solid node,label=right:{$x'$}]{}
child{node[solid node,label=below:{$(a_5,b_5)$}]{} edge from parent node[left]{$C$}}
child{node[solid node,label=below:{$(a_6,b_6)$}]{} edge from parent node[right]{$D$}}
edge from parent node[left]{$L$}}
child{node(6)[solid node]{}
child{node[solid node,label=below:{$(a_7,b_7)$}]{} edge from parent node[left]{$C$}}
child{node[solid node,label=below:{$(a_8,b_8)$}]{} edge from parent node[right]{$D$}}
edge from parent node[right]{$R$}
}edge from parent node[right,xshift=3]{$B$}
};
% information set
\draw[dashed,rounded corners=10]($(1) + (-.2,.25)$)rectangle($(2) +(.2,-.25)$);
% specify mover at 2nd information set
\node at ($(1)!.5!(2)$) {Jogador 2};
\draw[dashed, rounded corners = 10]($(3) + (-.2,.25)$)rectangle($(6) +(.2,-.25)$);
\node at ($(4)!.5!(5)$) {Jogador 1};
\end{tikzpicture}
\end{center}
\end{document}
So I open LyX, copy all the code between \begin{document}
and \end{document}
, and put the following in the document preamble:
\usepackage{tikz}
\usetikzlibrary{calc}
But when I try to preview/export to pdf, I get the error I copied above. Can anyone help me, please? Thanks!
