ErrorDialogs.py: by Christopher J. Fama (trading under the name

This code is released under the auspices of the modified version of
|
|
the GNU Library Public License (LGPL) that constitutes the license
|
|
under which the GUI package wxPython is released [see the file
|
|
LICENSE.TXT accompanying that distribution). I must also thank Graham
|
|
Boyd, of Boyd Mining, and CEO of the Minserve group of companies
|
|
(www.minserve.com.au), for kindly allowing the release of this
|
|
module under a "free" license, despite a certain part of it's
|
|
development having taken place while working for him...
|
|
|
|
Please note that this code, written for Python 2.1, is derives from
|
|
code written when Python 1.5.2 was current. Although since Python 2.0
|
|
the sys.excepthook variable has been available, for ease and potential
|
|
backwards compatibility (or to be more realistic
|
|
backwards-PARTIAL-compatibility!), the code catches errors by
|
|
assigning a custom object to sys.stderr and monitoring calls to it's
|
|
writ) method. Such calls which take place with a new value of
|
|
sys.last_traceback stand as evidence that at interpreter error has
|
|
just occurred; please note that this means that NO OTHER OUTPUT TO
|
|
sys.stderr WILL BE DISPLAYED. THIS INCLUDES "warnings" generated by
|
|
the interpreter. As far as I am aware, unless your code itself writes
|
|
to sys.stderr itself, these will be the only things you miss out
|
|
on--and many, if not most or all, of these will occur before your code
|
|
even gets the opportunity to set one of these file-like objects in
|
|
place. If this is a problem for you and you can't work around it,
|
|
please contact means or the wxPython-users mailing list.
|
|
|
|
|
|
DOCUMENTATION:
|
|
|
|
This is a module to display errors--either explicitly requested by a
|
|
script or arbitrary interpreter errors--these needs arose in the
|
|
course of a commercial (contract) project, but were not developed in
|
|
the course of work on such [well, very little, albeit concurrently]...
|
|
[NBNB.Does not currently support display of other than interpreter errors.]
|
|
|
|
Usage, after 'from wxPython.lib.ErrorDialogs import *' (all
|
|
identifiers defined in this module begin with "wxPy", and many of them
|
|
with "wxPyError_", so there should be no namespace conflicts...):
|
|
|
|
wxPyNewErrorDialog (<win> (['frame='] <frame (can be None)>,
|
|
<OPTIONS>))
|
|
...
|
|
wxPyDestroyErrorDialogIfPresent () # e.g. when top frame destroyed)
|
|
|
|
for unhandled errors, or
|
|
|
|
returnval = wxpyNonFatalError (<frame (can be None)>,
|
|
<HTML message>
|
|
[,<OPTIONS>])
|
|
or
|
|
returnval = wxPyFatalError (<HTML message>,
|
|
[,<OPTIONS, an extra one of which may be
|
|
'frame=' <frame (defaults to None)>>])
|
|
or
|
|
|
|
wxPybNonWindowingError (message)
|
|
|
|
for explicit errors.
|
|
|
|
<win> is one of
|
|
wxPyNonFatalErrorDialog
|
|
wxPyFatalErrorDialog
|
|
wxPyFatalErrorDialogWithTraceback
|
|
wxPyNonFatalErrorDialogWithTraceback
|
|
wxPyNonWindowingErrorHandler
|
|
|
|
and the OPTIONS (with defaults) are: (please note that the options for
|
|
wxPyNonWindowingErrorHandler / wxPyNonWindowingError are 'almost' a (small))
|
|
subset of these):
|
|
|
|
'modal' [default 1]: block until dismissed.
|
|
|
|
'programname' [default "Python program"]: appears inThe
|
|
caption of the dialog, amidst it's text and (by default) in mailings.
|
|
|
|
'whendismissed' option, if given, this should be a string, to be
|
|
executed in a restricted environment (see rexec module) after
|
|
dialog dismissal. Typically, this should be Python code to "clean
|
|
up" after what was presumably the partial execution of some
|
|
operation started by the user, after the unexpected interruption
|
|
by some error [which--at least the way I work, means an unexpected
|
|
error in the code, since exceptions that may be raised by some
|
|
foreseen (in a programmatic sense) should normally be handled by
|
|
try...except clauses].
|
|
NOTE THAT CURRENTLY THE rexec CODE IS NOT WORKING, SO THIS IS JUST DONE
|
|
BY exec...
|
|
|
|
'mailto': if None, give no "e-mail support" option, otherwise this
|
|
is meant to be an address for 'bug reports'; a command button will
|
|
be created for this, which pops up another dialog [Linux], or a window of
|
|
another program [Windows].
|
|
|
|
On Windows, this will launch your mailer (assuming your mailer
|
|
would start when a file with the '.eml'extension is double-clicked
|
|
in Windows Explorer--this will be the case for Microsoft Outlook
|
|
Express [tm and all those legal necessities] if installed, and the
|
|
association has not been taken over by some other program. On
|
|
Linux, it will open a file dialog to save the message, by default
|
|
as a '.html' file...{Please note that, on Windows and with current
|
|
(when I got the machine I'm writing this on--early 2000) versions
|
|
of Outlook Express, you may need to enter your e-mail address in
|
|
the box beside the "mail support" button.)
|
|
|
|
The template for the mail message is in the 'MessageTemplate'
|
|
attribute of the dialog-derived class in question (e.g.,
|
|
wxPyNonFatalErrorDialog). Search for this in the code below to
|
|
see the default (note that this template is in HTML format). This
|
|
attributes uses the '%{name}s' string conversion feature of Python
|
|
[see sec.2 of the Python Library Reference]; allowed Lance are:
|
|
programname version exceptionname exceptionvalue
|
|
extraexceptioninformation traceback
|
|
|
|
'version': str(this) will appear after 'Version' below "Error in
|
|
<programname>" at the top of the dialog.
|
|
|
|
EXAMPLES:
|
|
|
|
sys.stderr = wxPyNonFatalErrorWindowWithTraceback (
|
|
parentframe,
|
|
programname='sumthing',
|
|
mailto='me@sumwear',
|
|
whendismissed="from wxPython.wx import * ; wxBell()")
|
|
|
|
FOR INTERNATIONAL [NON-ENGLISH-SPEAKING] USE:
|
|
wxPyNonFatalErrorDialog and relatives have the method
|
|
SetText(Number NUMBER, STRING)
|
|
|
|
where STRING is to displayed in the wxStaticText control with ID
|
|
wxPyError_ID_TEXT<NUMBER>--see the automatically-generated code
|
|
for information about the meaning of these...

# as a personal endorsement: it is truly a brilliant time-saver!

# to the automatically-generated source: "parent.sizerAroundText = "
