Creating tree of trees in TikZ












1















I would like to create a tree in TikZ whose nodes are trees themselves.



I have the following piece of code:



documentclass{standalone}

usepackage{tikz}

usepackage{tikz-qtree} 



tikzset{% 

    every picture/.append style={

      grow'=up,

      sibling distance=.5em

    }

}



begin{document}



begin{tikzpicture}[baseline=-.3em]

  node[draw] {

    begin{tikzpicture}

      Tree 

      [. $+$ 

      node[draw]{

      begin{tikzpicture}

       Tree

       [. $+$ [. $+$ $a$ $b$ ]

           [. $+$ $c$ $d$ ] ]

      end{tikzpicture}

      }; 

      node[draw]{

      begin{tikzpicture}

       Tree

       [. $+$ $e$

           $f$ ]

      end{tikzpicture}

      }; 

      ]

    end{tikzpicture}

  };

end{tikzpicture}



end{document}


The problem is that the nodes of the outer tree are not connected right:



enter image description here



I think the reason is that qtree somehow "still sees" the inner nodes. Is there a way to let TikZ "unsee" the inner nodes? Something like the opposite of "remember picture"?



I can always export the inner nodes as a separate pdf and then reinclude it, but I was looking for a more elegant option, if possible.

    You are nesting tikzpictures which should be avoided.

Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

Image
up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title.
