Hi all, been playing with urwid for a few days and from what I see it
will really suit my needs for a terminal interface to a prototype
project I'm working on. We are writing an application using mpi4py to
distribute some significant calculations to a cluster. The only node
displaying the interface is the head-node and this is already setup and
working. The problem is that when executing under mpi it seems to use a
non-default descriptor as it reroutes piped communications to a separate
buffer on the head-node (from all children too) and this screws up
urwid. I've been over and over the reference and examples I could find
but none seem to show anyone dealing with this type of issue.
I looked at the source for the raw_display class and it assumes the fd
is '0' for default sys.stdin I'm guessing? Is there a way that I can
specify the terminal/buffer using core urwid functionality? It seemed
like, since when using MainLoop you can set a specific "Screen" object
but I cannot figure out how to create a custom one.
Any help would be much appreciated. The actual (and vague) error I'm
seeing is:
