Hello everybody,
Now my question is: Could a prompt be a useful part of matplotlib?
I worked on this some time ago, I never got to the point where I
thought it was ready for production but it is close. There is a
problem if usetex is enabled, because partial tex strings will cause
errors. But you can use it with regular text or plain text.
Give it a whirl -- I don't mind including tit in matplotlib.widgets
if people think it would be usefult. I do think there is a niche for
these kinds of things where people want brain dead simple widgets w/o
having to deal with GUI toolkits.
I'm pasting the example below, and also attaching it in case the lines
get wrapped

Re: [Matplotlib-users] ANN: matplotlib-0.90.1
Dear Werner, This seems to be an unintended side-effect of reorganizing the mpl data file location that I did prior to this release. (I.e. it's not your code that broke, I think it's mpl.) Unfortunately, since I didn't (and still don't) use py2exe, it will be hard for me to fix this. Can you send a patch that gets py2exe working again? Thanks, Andrew Werner F. Bruhin wrote: Werner F.

I notice the alignment problem. But it looks like you are close. On my machine (win32), the 'enter' key didn't work either. It works like a backspace. That sounds like what Matthias reported.
