Hi all,
I have set up an event handler and function to perform actions when a
user presses certain keys in the plot window. The function needs access
to variables that are in the main function. How do I pass these
variables to the function.
In OnKeyPress, ImageNumber and Li are objects in the main program. Any
ideas on how to pass them? Thanks
plt.connect('key_press_event',OnKeyPress)
def OnKeyPress(self,event):
print 'button= ',event.key, event.xdata, event.ydata
if event.key == 'm':
ImageNumber = ImageNumber + 1
if event.key == 'n':
ImageNumber = ImageNumber - 1
rawimage = Li.GetImage(ImageNumber)
plt.imshow(rawimage)
plt.title("Image number %3d" % (ImageNumber))
plt.draw()
