wxmpl isn't another GUI - it's what you use to embed matplotlib windows 
within wxPython (and therefore also can be used to embed them within 
PythonCard); telling you about wxmpl is in response to the part of your 
original post saying "or open a window to plot in"

wxmpl ?  Yet another GUI.  :-)Well, that's good.  I'll check it 
out.  I did get PythonCard and it looks pretty good, too.  Nice to have 
a choice.  Now EVERYONE STOP.   NO MORE.   :-)

I got around the loss of Traceback.  wxPython has a mechanism to set the 
redirection.  Just putting it to False causes the usual Terminal 
output.  So that now works.  (Yes, it was in the book.)

Take a look at wxmpl. It helps you embed a matplotlib window in a 
wxPython app. It's pretty handy, once you get the hang of wxPython. 
Also, depending on what kind of data you are looking at, 
wx.lib.floatcanvas might be useful (shameless plug, I wrote it)

This is a BBEdit thing, really, I find it easiest just to run from the 
terminal command line, and see your tracebacks there.

For really simple stuff, you can just:

app = wx.App()
image=wx.Image('/Users/louispecora/Code/python/test_folder/wxPython_learn/rappin_cover150.jpg',wx.BITMAP_TYPE_JPEG)
frame = Frame(image)
frame.Show()
app.MainLoop()

I'm pretty sure the default wx.App directs errors to the console.

If you're still stuck - I'd suggest asking on the pythoncard mailing list.

Got it, ran sudo python setup.py install, seemed to go OK.  Ran 
minimaltest and it could not find PythonCard module.  I have a path to 
the PythonCard directory (folder) in my .pth file in the proper place 
down in Library/Frameworks/python... etc.

Not sure why it can't see it.  Other added packages are found fine by 
python.

I am running on MacOS X 10.4.1 with Python 2.4.1 through the editor BBEdit.

I've checked paths and spellings.  No errors so far.  Any hints?

It's under development - 0.8.2 will be out any day now, and contains a 
fair number of enhancements, including some big ones:

 - codeEditor handles multiple windows (using tabbed notebook style).
 - layoutEditor allows selection of, and operation on, multiple components
   (e.g. to align them, move them together, etc.)
 - layoutEditor gives direct access to all properties
 - additional samples, better Unicode handling, enhanced walk-through 
(tutorial style) documentation

I'm struggling through the mechanics of releasing 0.8.2 - but you can 
get it already via anonymous cvs (see the instructions on the "cvs 
access" link from www.pythoncard.org )

The mailing list is pretty quiet - but generally responsive when 
questions are asked.

Yep, the redirect works.   I haven't tried the other suggestion of 
opening a messagebox dialog to hold the stdout window open.  That would 
be nicer since it involves direct feedback instead of going to a file.  
But still nice to finally see what the problem was.

It occurs to me that if you added an OnExit() handler to your app --  
any app that's giving quit-too-soon trouble. The handler could simply  
put up a wx.MessageBox, which gets an OK from the user. This would  
pause the app on the way out, and therefore permit the normal app  
output window (without changing redirection) to stay onscreen as long  
as one liked. A little baroque, but pretty easy.

Yes, I've messed with them a little.  Really very nice ... and 
tempting.  I'm on the fence.  I got this wxPython book and it looks 
cool, but I really don't need full-blown GUI apps, but then I may look 
into boa... too many choices.   :-)   But that's a good thing.   Sometimes.

I'm running from BBEdit.  Someone else pointed me to the link that 
showed how to do a redirect output.  When I did that I got the 
traceback.  I wish there were a way to keep the popup window with the 
traceback info open, but it quickly closes and the app quits.  
Redirecting found the error, but it is an extra step.

Thanks for the link and the hint on boa.  I've heard of the latter, but 
never looked into it.  I really do numerical calcs, but occasionally 
need a simple GUI dialog or open a window to plot in (very simple), but 
who knows, boa might be the ticket.  Thanks, again.

Have you checked if there's anything in /Applications/Utilities/ 
Console.app? If you run scripts by double-clicking them in the  
Finder, that's where the output should be going.

Kevin

Charles is right:http://www.wxpython.org/docs/api/wx.App-class.htmlHave you looked at boa-constructor on sourceforge?
boa-constructor.sourceforge.netI used to use it when I was a bigger-than-I-am-now linux geek and found it quite useful for building one-off gui toys.  I found the learning curve more bearable using it.

If I recall correctly, this syndrome is covered in the book. It  
happens because the diagnostic's going to a window that closes when  
the app does. Look up wx.App(redirect=True) in the index -- you can  
write the diagnostic to a file and examine it at leisure. Sorry, I'm  
doing this from memory so the details are hazy.

Personally I am with Bill, I like Jython but it unfortunately has  
fallen way behind in Python versions.
But it has teh advantage that Java is supported on all main 'cross'  
platforms.

[Pythonmac-SIG] wxPython -- some disappointment using it.

[Louis Pecora]

I bought the wxPython in Action book and started trying the simple 
examples in Chap. 1.  One thing I have run into is rather 
disappointing.  Many errors (e.g. I typed return true, instead of return 
True) do not give the beloved Python tracback.  That's one of the nice 
things that made me choose Python.  Somehow once the app is launched if 
there is a bug it just quits without any information.  I am now 
struggling to find out why example 3 (hello.py) won't work.  I've been 
over it dozens of times checking indentation, spelling, etc.  But the 
app never gets into OnInit (determined by the old fashion way of putting 
print's into the program at strategic stages).   A window flashes open 
and then disappears.  Process exited in the terminal.

How are others using wxPython?  Do you find you need to run in a 
debugger?  Does that help?  What do you recommend? 

Thanks for any suggestions.
