Thanks!
I found the solution...
[update 2013-01-23]
def popup(msg="", timeOut=0, posX=20, posY=70) # 2013-01-23 onidarbe () gmail
# Popup a message (including html-tags & \r) with a timout and auto-resize the window
# A click on the popup-window will disable timeOut and has to be closed manually
# To see how it's working, add border;1px solid black; in the <div style='...'>
htmlCode = %{
<html onclick='clicked();' >
<div id='div' style='float;left; white-space;nowrap;' >
#{msg.gsub(/\r/,"<br>\n")}
</div>
<script type='text/javascript'>
width=document.getElementById('div').offsetWidth;
height=document.getElementById('div').offsetHeight;
document.write("<input type='hidden' id='width' value='" + width + "'/>");
document.write("<input type='hidden' id='height' value='" + height + "'/>");
function clicked() { location = 'skp;clicked' };

win = UI;;WebDialog.new( "" )

# "View source" with Windows Notepad needs to have \r\n
win.set_html( htmlCode.gsub(/\r\n|\n\r|\n|\r/,"\r\n") )
# Although WebDialog without pref_key doesn't keep size or location, set_size does!
# Thereby start with a smaller window instead of a larger previous version
