Don't understand wxPython event handling
by Robert April 1, 2004

April 1, 2004

Hello list, could somebody point me to a good reference about wxPython event handling? I have seen many examples but which one is the best. Waht are the advantages and disadvantages? Can you also have a short look at the example below and give me some comments, please? Example: I have implemented (or copied from somewhere) one event in two flavours. Both work, but which one is the best? Or does anybody have a better implementation. EVT_NEXT_PAGE_ID = wxNewId() def EVT_NEXT_PAGE( win, func ): """Your documentation here""" win.Connect( -1, -1, EVT_NEXT_PAGE_ID, func ) class showNextPageEvent(wxPyEvent): def __init__(self, windowID): wxPyEvent.__init__(self) self.SetEventType(EVT_NEXT_PAGE_ID) or EVT_NEXT_PAGE_TYPE = wxNewEventType() def EVT_NEXT_PAGE( window, function ): """Your documentation here""" window.Connect( -1, -1, EVT_NEXT_PAGE_TYPE, function ) class showNextPageEvent(wxPyCommandEvent): eventType = EVT_NEXT_PAGE_TYPE def __init__(self, windowID): wxPyCommandEvent.__init__(self, self.eventType, windowID) def Clone( self ): self.__class__( self.GetId() ) Thank you Robert

Python Documentation Blows!

I do know C but I still find working from the wxWindows docs > frustrating with a lot of trial and error required. As was mentioned in a recent thread python is definitively the tool for applications with complex code and no or little UI. For UI-intense apps, win32 C# and delphi are still hard to beat Possibly a smart (and not necessarily big) wxpython book could prove a decisive argument for wxpython and python as well specifically for the "MS visual *" and delphi user communities. Is it time for the python community to commit a bit more to the wxwidgets/wxpython environment? I feel so François

But I access solaris boxes from a PC. And since I have a mapped network drive, I can use PC tools to work on my unix files. I agree, installing stuff on windows is easy. My comment about cygwin is that it's even easier than easy. I just have to check off the Python box. That gives me opportunity to try it for small things. By no means am I comparing cygwin to other unix environments for the PC. I enjoy it out of convenience. Most of my stuff is on the solaris, and cygwin gives me a nice posix shell without leaving the windows environment.

Just magic ...
by a-steinhoff＠web.de April 1, 2004

April 1, 2004

Hi all, I'm just porting a piece of python code for using a different database. When I run the original version .. the type of 'set' is a tuple ... and is magically in the new version a 'class instance'. The code is the same in both versions: ins_list = [(0,1,2,3),] self.IMpos =0 for set in ins_list: setdata = (self.IMpos,) + set[1:] Any ideas why set is treated as a 'tuple' and in the other case as a 'class instance' ?? (Python 2.3.3 ) Regards Armin

The lines if a = 3 print 'Yeah baby' are still *unambiguous*.... yet the interpreter refuses to understand you...... Theres no reason why a single '=' shouldn't be understood in a conditional.... As for needing a ':' to allow statements after a 'def' or a conditional.... python already has the ';' for that... why insist on a ':' Regards, Fuzzy http://www.voidspace.org.uk/atlantibots/pythonutils.html

ANNOUNCE: 'goto' for Python
by Richie Hindle April 1, 2004

April 1, 2004

Entrian Solutions is pleased to announce version 1.0 of the 'goto' module. This adds the 'goto' and 'comefrom' keywords to Python 2.3, adding flexibility to Python's control flow mechanisms and allowing Python programmers to use many common control flow idioms that were previously denied to them. 'goto' example: breaking out from a deeply nested loop: from goto import goto, label for i in range(1, 10): for j in range(1, 20): for k in range(1, 30): print i, j, k if k == 3: goto .end label .end print "Finished\n" 'comefrom' example: letting cleanup code take control after an error. from goto import comefrom, label def bigFunction(): setUp() if not doFirstTask(): label .failed if not doSecondTask(): label .failed if not doThirdTask(): label .failed comefrom .failed cleanUp() Computed 'goto's are also supported - see the documentation for details. Computed 'comefrom's are planned for a future release. Documentation and further examples: http://entrian.com/goto/index.html Downloads: http://entrian.com/goto/download.html The 'goto' module is released under the Python Software Foundation license, and requires Python 2.3 or later. Please note that this version does not work at the interactive Python prompt - code importing 'goto' must be in a .py file. This restriction will hopefully be lifted in a future release. -- Richie Hindle richie(a)entrian.com

ftpmirror.py in reverse?
by Harry George April 1, 2004

April 1, 2004

I maintain a website on a local machine, and want to maintain a clone of it on a www-visible remote machine via ftp. I.e., local to remote. Going remote to local, ftpmirror.py would (I understand) do the job. Is there some tool available (or even a parameter for ftpmirror.py) which can do local-->remote? -- harry.g.george(a)boeing.com 6-6M21 BCA CompArch Design Engineering Phone: (425) 342-0007
