Re: [Matplotlib-users] capturing arrow key events

[Tim L. <ti...@cs...>]

Just to follow up on this, I made the required changes to the other
backends and they worked fine. GTK and GTKAgg had the same broken
behaviour while TkAgg, WX and WXAgg worked fine (don't have qt installed).

I'll bring all my libraries up to date (thanks for 0.80 tonight) and dive
into the pygtk stuff a bit deeper to see if I can find out what's
breaking.

Having looked through a bit more mpl code I'd just like to say that I'm
very impressed with how simple it is to read. After working out what to
change in GTK, it followed an identical pattern in the other backends
which was very nice to see.

Cheers,

Tim Leslie
