[Matplotlib-users] matplotlib picking mouseevent.key=None
Say, on Windows, the mouseevent.key correctly comes in as control, shift, or a letter...on Linux, it does notI am always getting None. is this a known problem with known solution? thanks, gsal -- View this message in context: http://old.nabble.com/matplotlib-picking-mouseevent.key%3DNone-tp33494747p33494747.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- Keep Your Developer Skills Current with LearnDevNow!

Also, which mouse event are you using where you expect a key value? I would expect to use a key press event to process .key values. Ben Root -- Keep Your Developer Skills Current with LearnDevNow!

If you post a minimal script that exposes the problem, and run it with --verbose-helpful and post the output, we can see if we can replicate the problem.

For now, there isn't much of a problem with the application, it is just that I inspect the mouseevent from within the picker function and I get this None 1 where None is the key 1 is the mouse button pressed and the rest is the artist -- View this message in context: http://old.nabble.com/matplotlib-picking-mouseevent.key%3DNone-tp33494747p33494825.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- Keep Your Developer Skills Current with LearnDevNow!

Re: [Matplotlib-users] matplotlib picking mouseevent.key=None
o.k., here is some minimal code...what am I doing wrong? Within the picker (def pkr)...I would like to be able to see the mouseevent.key value, but this is always None...is this the expected behaviour? Is mouseevent.key not set at this point? Anye hints would be greatly appreciated.
