hello,
have an error occuring that causes my app to crash. I found a few other email
listings similar to my problem, but there were no responses that I could learn
from.
I am quickly plotting an array as it grows. I have a wxframe, canvas, figure
and an axes. I clear the axes, plot the array, draw the canvas. this is
happening at about 5 hz. I get the error message listed below and it only
occurs when the mouse is hovering over the canvas or a button is pressed. I
disabled these events from my canvas yet I still get this error, so I am not
sure it is something from my code.
If I am not doing all this fast redrawing. there is no problem, ie. if the
image is static I don't have this error. I suspect it has something to do with
the axes objects clearing and redrawing while a mouse or key event is
simultaneously being drawn.
Please advise as to how I may fix this problem. thanks for your help.
Jeff
