Re: [matplotlib-devel] Another try at interactive gui thread

[Steve C. <ste...@ya...>]

Regarding Baptiste's patch
- I'm not too keen on the idea of wrapping gtk.gdk.threads_enter() /
gtk.gdk.threads_leave() around every GDK function call.
- I share Fernando's concern with possible problems when adding new
widgets or embedding a matplotlib window into something else.

My understanding is that wrapping gtk.gdk.threads_enter() /
gtk.gdk.threads_leave() around GDK functions is not necessary if all the
GDK calls occur in the same thread. So I think a simpler solution is to
arrange for all gui calls to go to a single thread and do away with
enter()/leave().

I created a module that allows interactive matplotlib access from a
python shell, its a modified version of
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/65109

This method seems to work for me (on Linux) and is not very intrusive to
matplotlib code - it just requires that 'gui_cmd()' is used to execute
all gui commands when in interactive mode.

Any comments?

Steve
