Charlie,

Yes. I'm using numarray for numerix. I've specified this in a local matplotlibrc
file that configures my application, as well as the default matplotlibrc file in
the C:\Python24\Lib\site-packages\matplotlib\mpl-data directory.

My .exe is called VizTool.exe. The output from VizTool.exe.log is :

Traceback (most recent call last):
  File "VizTool.py", line 2, in ?
  File "VizTool\Controllers.pyo", line 4, in ?
  File "VizTool\GraphPanels.pyo", line 1, in ?
  File "wxmpl.pyo", line 32, in ?
  File "matplotlib\numerix\__init__.pyo", line 145, in ?
ImportError: No module named random_array

Any suggestions?

As always, thanks for the help.

Further little testing I forgot...

Printing disconnect_id gives me an id, so there is an answer from 
self.control.mpl_connect() ...

I also tested with 'key_press_event' to see if the mouse events were the 
problem, but no luck...

Hi,

I'm building a simple wxpython + matplotlib application using wxmpl (no 
pylab).

I'm currently trying to get X and Y coordinates of a point I click 
inside a graph plotted in a PlotPanel.
So I'm trying to connect the PlotPanel to a button_press_event. The 
problem is it fails silently. No error, but it seems that the connected 
function is never called and even that the connecting itself never happens.

My hypothesis: I see that the PlotPanel has default zooming when 
selecting a box with the mouse, so I think it is already connected with 
button_press_event? should I disconnect? how (what's the id)? Should I 
use something different from PlotPanel?

-------------------
Here are relevant code snippets:


class MainWindow(wx.Frame):
         def __init__(self,parent,id,title):
 
wx.Frame.__init__(self,parent,ID_FRAME,title,size=(800,600),style=wx.DEFAULT_FRAME_STYLE|wx.NO_FULL_REPAINT_ON_RESIZE)

             self.control=wxmpl.PlotPanel(self,1)

[Then, if I send the right wxpython event (I want my plot giving me 
coordinates only when I say the gui to do it), I call ClickPlot, that 
should turn on the connection between the mpl event 'button_press_event' 
and another function, for my PlotPanel.]

def ClickPlot(self,event):
      #test code
      print 'you're calling ClickPlot()'
             def click_me(mpl_event):
		#test code
                 print 'you click me!'
                 if mpl_event.inaxes:
                     print 'in axes too!'
             	
    disconnect_id=self.control.mpl_connect('button_press_event',click_me)

--------------------------

I checked and ClickPlot() is called, but as said before, click_me() is 
not. Any idea? What could I do to figure out what's (not) happening?

Thanks,
Massimo

This appears related to the bug described in this patch

http://sourceforge.net/tracker/index.php?func=detail&aid=1444703&group_id=80706&atid=560722

When I reviewed this patch, I was concerned because I thought the fix
unneccessarily broke the API in order to fix the problem.  I haven't
heard yet from  Toon Verstraelen, who wrote the patch, about this
issue.  You may want to take a look at it and see if it fixes your
problem too.

I don't know how to solve it for pythonwin, maybe you could investigate it 
with a google search (thats how I learned about the problem and the solution 
for idle).

I suppose win32pipe is part of pywin32. If that is the case, I dont think I 
can support using it; we are trying to eliminate dependencies, not add to 
them. Subprocess is acceptable because it is part of the python-2.4 standard 
library and we were able to add it to the mpl tree for older versions of 
python.

Darren,

I prefer using PythonWin to IDLE. Any ideas how to solve the
subprocess.Popen() problem using PythonWin? What about using
"win32pipe"?

I forgot to mention, you may be able to avoid these errors by starting
idle=20
with the -n flag.
