    Nice! But, I think you should make the boxes have the same size.

    There’s a solution on TeX.stackexchange.com by Andrew Stacey (with a small, but, I think, important addition of mine), which works without dummy childs (this “[missing]” ones – where is the definition of them?), but is more difficult to understand, where to change the lengths (tip: look for “1cm”):

    Hi Speravir,

    thanks for the information! I will read Andrew's example.

    Btw. [missing] is explained in the pgf/TikZ manual, 18. Making trees grow, 18.5.3 Missing Children.

    Hi all!

    The Stacey's example is much better (Maybe can be published there ?). But if i searched for it, i hasn't been found yet. This example is not as complex as Stacey's, but it is constructed with simple code.

    Thanks.

    Frantisek.

    Hi Frantisek,

    I like your example because it's easy to understand, and it shows how to use missing children. Andrew's defines a nice growth function, a clever approach, and I think I will add it too, just will have a look at it soon.

    For anyone needing it, here's how you turn on arrows from parent-->child:

    edge from parent path={[->] (\tikzparentnode.south) |- (\tikzchildnode.west)}]

    I have a question concerning the aesthetics of this example. (It's a great example, by the way.)

    Backgorund to my question: The line from "texmf" to "doc" is thicker than the line from "texmf" to "texdoc". I suppose that this happens because near the root of the tree many lines overlap.

    My question: Is there any way to prevent this and thus to have the same line thicknes everywhere?

    Thank you.
