can you help me please and have a quick look at the following code?

this is the error if i press 'h' which triggers the code:
"ValueError: need more than 1 value to unpack"

i looked at the examples but didn't find any hint why my code doesn't work but
the example's one does.

Hello,

Your problem is here:
                # help overlay message
                # FIXME: overlay funktioniert ned.
                help = urwid.Text('Help\n----\n"h"\t ... this help screen\n"ESC"\t ... 
exit this help screen\n"ALT+q"\t ... exit the programm', align='center')
                help = urwid.AttrWrap(help, 'help')
                help = urwid.Overlay(help, topframe, 'center', None, 'middle', 
None)
                #help = urwid.Overlay(help, topframe, 'center', 1, 'middle', 
None)

You are putting a flow widget (Text) inside an Overlay. The overlay is expecting a fixed widget because your width and height are set to None.

What you are trying to do will probably work in a future release of Urwid, I just haven't gotten around to implementing the ability for Text to behave like a fixed widget yet. I guess I should get to work on that! :-)

You need to:
1. set a value for width and height in your Overlay, so that it expects a box widget
2. wrap your Text widget in a Filler widget, which is a box widget.

This means that it won't intelligently resize based on your text for now, but that's the best option I can see at the moment.

Ian
