I want to add styles to my nodes that draw additional paths inside of the node.

For example (without proper placement of nodes)

\node[draw,circle,lVert] {};
\node[draw,circle,lHor]  {};
\node[draw,circle,lVert,lHor] {};

shall result in these nodes:

Keywords

strike through node, line in node, strike through style, cross, path as style

Adapting the solution of the following question (thanks to Claudio's comment): Creating a seamless XOR symbol as node

I ended up with this working and extremely simple code:

\begin{tikzpicture}[
    every node/.style={draw,circle},
    hVert/.style={append after command={(\tikzlastnode.north) edge (\tikzlastnode.south)}},
    hHorz/.style={append after command={(\tikzlastnode.west) edge (\tikzlastnode.east)}}
  ]
  \node[hVert] (a) {};
  \node[right=of a,hVert,hHorz] (f) {};
  \node[right=of f,hHorz] (b) {};
\end{tikzpicture}

Another option: declare three new shapes.

It would be better to declare only one new shape with some parameter to draw horizontal, vertical or both lines, but I don't know how to do it.

\documentclass[tikz, border=2mm]{standalone}

\pgfdeclareshape{hVert}

  • I thought about this. But I'm going to require even more decorations and the number of shapes would grow exponentially. Also I need to decorate both circles and squares. But maybe this solution serves someone else. – ziggystar Feb 13 '14 at 19:00
