Hi all...I am connecting an event handler that collects user input via
raw_input. When using GTKAgg as my backend, this works but requires the
user to first hit 'enter' before the raw_input prompt is displayed--this
extra step of hitting enter is quite cumbersome! When I use the TKAgg
backend, I get this error message:
Exception in Tkinter callback
Traceback (most recent call last):
File "/local/lib/python2.5/lib-tk/Tkinter.py", line 1403, in __call__
return self.func(*args)
File
"/local/lib/python2.5/site-packages/matplotlib/backends/backend_tkagg.py",
line 208, in button_press_event
FigureCanvasBase.button_press_event(self, x, y, num, guiEvent=event)
File "/local/lib/python2.5/site-packages/matplotlib/backend_bases.py",
line 911, in button_press_event
func(mouseevent)
File "tktest.py", line 15, in printpoint
color = str(raw_input("Enter color: "))
RuntimeError: can't re-enter readline
I am using Tcl/Tk 8.4.14, python2.5, and matplotlib0.90. The test code I'm
using follows.
Thanks for any help!

import pylab,scipy
def printpoint(event):
color = str(raw_input("Enter color: "))
text = "%d , %d" % (event.xdata,event.ydata)
pylab.text(event.xdata,event.ydata,text,color=color)
data = scipy.arange(100.)
pylab.plot(data)
pylab.connect('button_press_event',printpoint)
