问题
I alreay can implement chat daemons using gevent and zeromq, but I'd like to make a console UI for them.
My first attempt with ncurses failed, so I tried Urwid and found out that the project nigiri was going exactly what I wanted:
I studied the source code, but being unfamiliar with console UI programming, I failed finding out the part that were producing this result (especially since it used multiple tabs), while I guess I have to play with the connect signal.
Does anybody have a snippet that can does this ?
I don't need the whole program, I can handle the communication, the daemons, the options and all the rest myself.
Just the basics to setup the UI, enter some text at the bottom, and asynchronously notify the top panel to add some text while it doesn't block the bottom ouput.
Thanks

In computing, if you are not smart, you gotta be patient. I just applied the good old try/except keyword to my programming method:
- remove something from the source that doesn't relate to my feature
- if ok, go to 1 until the is only the essential code remains
- if it crashes, understand this part and why it's essential and replace it with a code that suit my needs then go back to 2
I just stripped down the nigiri source code untill it fits in one file.
It works. Now I gotta figure out how to make the urwid and zeromq main loops play nice together.
