clabel( CS, manual=True ) / ginput_manual_clabel.py - broken?

Community matplotlib-users
#1

Hello list,

I run into trouble with the formelly working
example ''ginput_manual_clabel.py'' or the following minimal example (in
ipython -pylab)

CS = plt.contour(reshape(arange(20)%3, (4, 5)), [0, 1, 2])
CL = plt.clabel( CS, manual=True )

First of all I get a DeprecationWarning during the startup (for GTKAGG and
TKAGG)

/scratch/michler/SOFT/lib/python2.5/site-packages/matplotlib/backend_bases.py:1793:
DeprecationWarning: Using default event loop until function specific to this
GUI is implemented
  warnings.warn(str,DeprecationWarning)

and the worse point is that I am not able to select some clabel-positions
(GTKAGG, TKAGG and WXAGG) and
if I try to leave the selection mode I get

GTKAGG:
<type 'exceptions.TypeError'>: stop_event_loop() takes exactly 1 argument (2
given)
/scratch/michler/SOFT/lib/python2.5/site-packages/matplotlib/blocking_input.py(196)mouse_event_stop()
    195 # returned before using data.
--> 196 self.fig.canvas.stop_event_loop(event)
    197

TKAGG:
  File "/usr/lib/python2.5/lib-tk/Tkinter.py", line 920, in update
    self.tk.call('update')
_tkinter.TclError: can't invoke "update" command: application has been
destroyed

WXAGG:
nothing

Could anybody help me?

Kind regards,
Matthias

I can reproduce this bug with the current svn.
Matthias, can you file a bug on this in the issue tracker?

I think the bug is related with the changes made back in august.

http://old.nabble.com/ginput-default-mouse-configuration-td24924861.html

Attached is a quick fix, so please test it.
I didn't thoroughly follow the changes made related with the above
conversation, so I hope those involved (Jack Sankey, John and Gaël)
take a look and make a relevant changes if necessary.

Regards,

Hi JJ,

I'm sorry for the late response - I was on chrismas holidays and in fact even
now I have not much time.
I tested you patch and there arise labels - thanks a lot so far.

Where should I post the bug report? on sourgeforge.net in the "Bug Tracking
System" of matplotlib?

Kind regards,
Matthias
