[Tex/LaTex] Create flow chart with different sized boxes

flow charts

I have a problem creating a flowchart with tikzpicture. I want it to look like this:

this is how far I got it – using some example that I found:

\documentclass[border=10pt]{standalone} 
\usepackage[T1]{fontenc}

\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage{verbatim}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[sibling distance=25em,
  every node/.style = {shape=rectangle, rounded corners,
 draw, align=center,
  top color=white, bottom color=white}]]
  \node {Absicht}
  child {node {absichtliche Handlung} 
    child {node {Wie viele Handlungen? \\ Wissen ohne Beobachtung}} 
    child {node {Warum-Frage}
        child {node {Zurückweisung}
            child {node {»Ich wusste nicht...«}}
            child {node {»Ich tat es\\ unwillkürlich«}}}
        child {node{Beantwortung}
            child {node {»Einfach so!«}}
            child {node {Motive \\(sind keine mentalen Ursachen.)}
                child {node {Motive im Allgemeinen}}
                child {node {rückwärtsschauende Motive}}
                child {node {vorwärtsschauende Motive}}}}}}

  child {node{Ausdruck der Absicht}};
\end{tikzpicture}
\end{document}

The Problem is the overlapping boxes and that it looks too symmetrical and therefore becomes to broad. Also it would be very good, if the size of the boxes would adjust automatically to the amount of text that is in it. I hope that the code is not to bad…

After short playing with sibling distance and changed width of two nodes, I obtain the following tree:

This image can be further improved. The code for above graph is:

\documentclass[border=10pt,
               tikz]{standalone}
\usetikzlibrary{trees}% <-- new

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}


    \begin{document}
\begin{tikzpicture}[
every node/.style = {shape=rectangle, rounded corners,
                     draw, align=center, fill=white},              
   level 1/.style = {sibling distance = 12em},% <-- new
   level 2/.style = {sibling distance = 12em},% <-- new
   level 3/.style = {sibling distance = 20em},% <-- new
   level 4/.style = {sibling distance = 11em},% <-- new
                    ]
\node {Absicht}
    [edge from parent fork down]
    child {node {absichtliche Handlung}
        child {node {Wie viele Handlungen? \\ Wissen ohne Beobachtung}}
        child {node {Warum-Frage}
            child {node {Zurückweisung}
                child {node {»Ich wusste nicht...«}}
                child {node {»Ich tat es\\ unwillkürlich«}}}
            child {node{Beantwortung}
                child {node {»Einfach so!«}}
                child {node {Motive \\(sind keine mentalen Ursachen.)}
                    child {node {Motive im Allgemeinen}}
                    child {node {rückwärtsschauende\\ Motive}}% <-- changed
                    child {node {vorwärtsschauende\\ Motive}} % <-- changed
            }}}}
    child {node{Ausdruck der Absicht}};
\end{tikzpicture}
    \end{document}

[Tex/LaTex] flow chart with defined width for the boxes

This shows two potential options for making a node where text width is set relative to the length of the text in the node.

\documentclass[border=5mm,tikz]{standalone}
\newcommand\foo[1]{node [text width={0.7*width("#1")}] {#1}}
\begin{document}
\begin{tikzpicture}[
   foo/.style={
       draw,
       % measure the width of the argument, and set text width to 60% of this
       text width={0.6*width("#1")},
       % use node contents to define the text of the node
       node contents={#1}
       }
]

\node[foo={this is some long text, with comma},at={(0,1)}];

\path \foo{This is another long text, also with a comma};
\end{tikzpicture}
\end{document}

And the macro version implemented for your tree. Note that I set the text width to whichever is larger of 30% the text length or 3cm, otherwise it wouldn't work well for shorter nodes. Note also that this method did not work for the node that had \textit in it, so for that one the text width is set manually.
