Building mxDateTime for Python 2.0
by Vincent Marchetti Sept. 24, 2001

Sept. 24, 2001

I am trying to re-compile the mxDateTime shared library to let me use DateTime in Python 2.0 -- the shared library provided throws exception on import about using the wrong version. I have never compiled any type of shared library before, so girding my loins and firing up CW 5 I set up a shared library project and: 1. included the mxDateTime.c code 2. included stub libraries PythonCore and MSL ShLibRuntime.Lib Result: -- Link failure, could not find function 'floor' I knew this is a standard C function, so I threw the stub MathLib into the pot and cooked. Got a bunch of warnings about duplicate definitions of math functions (in PythonCore and MathLib). Decided to ignore warnings. Successfully made the shared library, successfully imported DateTime into Python 2.0 (actually 2.0b1). However, the test script for mxDateTime failed an assertion. Basically, a function DateTimeFromTicks, which uses the floor function, fails to give predicted results. My question: Am I including the correct library in my project to get the "right" version of floor? Thanks, Vince Marchetti

cross platform GUI?
by John Schmitt June 7, 2001

June 7, 2001

So, in your collective experience, is tk actually useable to create decent Mac applications that are also decent Windows applications? I'd like to be able to use wxpython or tk and also pygame (http://pygame.seul.org/) but I'd like to target both Mac (OS9 and OSX) and Windows at the same time. How do you accomplish that? I know this topic comes up often in comp.lang.python, but I want a real Mac person's perspective rather that people who 'heard good things about GTK/glade/wxwhatever' and think the Mac is just a GUI with a slightly different color. Thanks for your input. John

Re: [Pythonmac-SIG] cross platform GUI?
by Sean Hummel May 31, 2001

I've written quite a few things in Python which use TK because I needed the apps to run on Windows, Macintosh and UNIX. However I found that the application while useable on all three platforms, it was very hard to make a simple dialog, without writing a new TK dialog/window class that read XML dialog templates. However because of the way TK works it can be quite annoying to write an application for. I find the most annoying thing, that there aren't default filters for edit boxes, and that list boxes act strangely when scrolled to different positions, and doing insertions. So if you don't care exactly how your application's GUI acts or looks, I'd suggest TK for Xplatform stuff. But if you do care, then something else might be called for. -----Original Message----- From: John Schmitt <jschmitt(a)vmlabs.com> Date: Thu, 31 May 2001 15:18:17 -0700 To: "'pythonmac-sig(a)python.org'" <pythonmac-sig(a)python.org> Subject: [Pythonmac-SIG] cross platform GUI? > > So, in your collective experience, is tk actually useable to create decent > Mac applications that are also decent Windows applications?

Question about Tkinter listbox
by Josh English May 31, 2001

May 31, 2001

I am new to python and I am using MacPython 2.1 and Tk 8.9 on Mac OS 9.0. I am having difficulty figuring out how to get the selected item in a listbox into an entry data field. I have tried the following code after lots of failed experiments: from Tkinter import * names = ['Josh','Steph'] class window(Frame): def sendname(self): index = namelist.curselection() # Fails here print index # for testing label = namelist.get(index) # Fails here print label # for testing root=Tk() namelist = Listbox(root) pos = 0 for name in names: namelist.insert(pos,name) pos=pos+1 namelist.pack(side=LEFT,fill=Y) namelist.bind('<Double-1>',sendname) nameentry = Entry(root) nameentry.pack(side=TOP,fil=X) window().mainloop() In Programming Python by Mark Lutz there is a ScrolledList class on page 372 and I've adapted the code for this. I'm ignoring the scroll bar and focusing on just this one issue. I want to get the nameentry field to reflect what is selected in namelist. Any suggestions? Josh English english(a)spiritone.com

Tkinter not multitasking
by David Glasser May 30, 2001

May 30, 2001

I have a fresh new installation of Python 2.1 with Tkinter (whatever version comes with the online installer) on MacOS 9.0. Whenever I run a Tkinter program (even one as simple as 00-HELLO-WORLD.py in Demo/tkinter/matt), it doesn't seem to yield any time to background applications. No redraws when windows are moved, no processing, no nothing. (Processing does happen when I print to the Tkinter console.) Is this a known problem where the only solution is to live with it until somebody gets around to fixing it? Or is this a problem with my setup? Thanks, David Glasser me(a)davidglasser.net

For non-TEXT files all Mac cvs clients will optionally allow the file to be put into the repository as binhex or macsingle format. This has a slight problem because it means that everything appears changed twice a year (when the Mac magically changes file times when switching from/to daylight saving time), but aside from that it works fine. The only problem is that you have to specify which file types have to be checked in as straight binary even though they may have a resource fork (images and soundfiles, mainly) and it's easy to forget to ad new types. Then you'll be checking the first .aiff into the repository and it'll work fine for you, but after a while the windows or unix users of the repository start complaining. One thing that I haven't yet found out how to do, maybe someone can help out here: is there a way I can tell unix-CVS that certain files need pre/postprocessing? In my cvstree on OSX (for which I use unix CVS) all my resource-fork files are unusable. Knowing CVS there's probably a way to do what I want, but I don't know of it yet... -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

Re: good CVS/ssh client for Mac?
by Gary Bringhurst May 27, 2001

We've been using SSH with the latest MacCVS client from the cvsgui project on sourceforge for a while now. It's still in beta, and crashes sometimes, but I've never had any serious problems. Mostly you need to avoid cancelling any activity over the ssh connection via command-'.' We also use the Windows client successfully (and happily). It's very nice. A disclaimer: I'm a friend and co-worker with Alex Parenteau who is the current maintainer.

Could you > give me a link please? Thanks. Well, good... Hmm. There's a Mac CVS client that talks ssh, so if you need checkin privileges on SourceForge it's about your only option (aside from lots of mumbojumbo with tunneling from MacCVS to NitfyTelnet and other magic). This is the "MacCVS Pro" client, from www.maccvs.org. Aside from ssh support (and a more good-looking GUI) it is much worse than MacCVS (from www.cvsgui.org): no support for .cvsignore, no Internet Config support to set the right creator/type for files, a strange and error-prone method for checking file modifications (based on files being check out readonly with the mac-standard "ckid" resource, and if you've edited the file there's really no way to find out whether you've actually changed it short of checking it in), every file is checked in separately (so mass changes result in massive mailings to the cvs-checkins mailinglist) and lots of other little gripes. All in all I'd switch back to MacCVS today rather than tomorrow (even the new version where they've ruined the GUI beyond all recognition:-) if it wasn't for SSH support. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

May 26, 2001

Jack, When you were about to move MacPython's CVS over to the Python's SourceForge project, you mentioned (on python-dev, I believe) that there is now a good CVS client for the Mac, that supports ssh and SourceForge access. Could you give me a link please? Thanks. -- David Goodger dgoodger(a)bigfoot.com Open-source projects: - The Go Tools Project: http://gotools.sourceforge.net - reStructuredText: http://structuredtext.sourceforge.net (soon!)
