+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...
