Ticket for tracking crashes in PyTools during dev

[GoogleCodeExporter]

This ticket is to help with tracking crashes in the PyTools plugin during 
development.

1) While closing Editra (wxPy2.9.1.1) - seems EVT_SHOW is getting sent after 
some of the window objects have been destroyed. Add separate handler and only 
handle during the show event and not during the hide event.

Got this one under the following scenario

1) Debug a script
2) Abort debug when stopped on breakpoint
3) Close debug window
4) Close Variables window
5) Close Stack window
6) Crash occured at this point, guess is from some async callback calling on 
one of the deleted shelf windows.

Issue noted in Comment 2 above corrected in latest svn

Original comment by CodyPrec...@gmail.com on 20 Apr 2011 at 1:28

[GoogleCodeExporter]

All above issues appear to be fixed with latest svn

Noting one more inconsistancy to investigate:

1) Open Debug window
2) Click start button
3) While its attaching close the debug window
4) Notice that the attach continues and that the first breakpoint will be hit
5) Reopening the debug window allows user to regain control over the debug 
session

Seems that the attach should either be aborted or canceled when the debug 
window is destroyed.

* possibly should add callbacks to shelf to check if a window can be closed. As 
a better solution may be to disallow closing the tab until after the attach 
completes. Needs further evaluation.

Additional not on above post:

Clicking Stop Debugging on the newly opened Debug window raises the following 
error:

Open PyExpressions shelf. Debug program.

You get error:
  File "build\bdist.win32\egg\PyTools\Debugger\ExpressionsList.py", line 120, in clearexpressionvalues
AttributeError: 'ExpressionsList' object has no attribute '_data'
