#---------------------------------------------------------------------------- # Name: ErrorDialogs.py # Version: 1.0 # Created: September--October 2001 # Author: Chris Fama of Wholly Snakes Software, # Chris.Fama@whollysnakes.com #---------------------------------------------------------------------------- """ ErrorDialogs.py: by Christopher J. Fama (trading under the name Wholly Snakes Software {Australian Business Number: 28379514278}). 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 ( (['frame='] , )) ... wxPyDestroyErrorDialogIfPresent () # e.g. when top frame destroyed) for unhandled errors, or returnval = wxpyNonFatalError (, [,]) or returnval = wxPyFatalError (, [," 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--see the automatically-generated code for information about the meaning of these...
