Plotting Widget problems
by W.T. Bridgman Oct. 31, 1998

Oct. 31, 1998

A few months ago, Konrad Hinsen posted a python plotting widget written using the Tk interface at http://starship.skyport.net/crew/hinsen/TkPlotCanvas.py I've tried using this in MacPython but it doesn't seem to run. It seems to just compile and do nothing. Has anyone had a similar experience and/or figured out what is missing? Thanks, Tom

pythonmac & GUI
by Bob Savage Oct. 30, 1998

Oct. 30, 1998

Hi, I have been slowly learning Python, but have yet to do anything with a GUI. I tried Tkinter a few times, but it doesn't seem to work reliably for me. I tried running the 'Hello GUI world' code from the Lutz tome, and I ended up not being able to quit from the Python IDE (the menubar changes to reflect the mini app, but 'quit' does not work, so all I can do is force quit??) The same thing happened on two different computers, BTW. I looked at the "FrameWork.py" file and the documentation in the Mac addendum to the reference, but I don't think I can do anything with that without at least one example (if someone has an example, even a small one, I would love to see it). That leaves learning the Macintosh Toolbox and the bindings offered in the various Python modules. I would prefer not doing that because I really want to hop on MacOS X as soon as possible (I'll be getting MacOS X Server as soon as it becomes available -- I really need the stability, for one thing) so I am leary of learning APIs that are about to go away. (Are there plans for carrying Python forward onto MacOS X / X server (Rhapsody)?) At this point it seems like my best bet is just wait and not get tied to a GUI framework until something or another firms up (Does someone have a better suggestion?) Thanks for the help, Bob Bob Savage _________________________________________________________________________ e^mail -> savage(a)2xtreme.net _________________________________________________________________________

Re: [Pythonmac-SIG] mac.chdir ?

Recently, "Steven D. Majewski" <sdm7g(a)virginia.edu> said: > SetFolder() seems to work for me, however what it does isn't what my > code fragment does. Yes, but as was mentioned before it only works if you have the right settings in the "general controls" control panel:-( I'm working on a different hook for setting the folder for the StandardFile calls, probably an extra optional argument that signifies the folder where you want to go. It's not simple, though, because it'll have to use the event hook, and that's already used for other things. > All I wanted was a quickie to set the current directory interactively: > > os.chdir( macfs.GetDirectory()[0].as_pathname() ) A good place to put this would be the interactive startup file, or, if you use the IDE, the scripts folder. > But this topic always tends to get confusing because the problem is > that there's TWO "current-directories" -- the POSIX/STDIO getcwd() > current-working-directory, and the Mac standard file dialog Current > Folder and they don't track each other of have any connection. This is because the MacOS doesn't really have a working directory concept. I keep noticing that various extensions also muck with Python's idea of the working directory: Click there it is! is one of them, and the valuefax receiver is another. There's unfortunately little to do about this, short of completely ignoring MacOS's working directory and keeping the working directory ourselves:-( > If there's a function missing from the set, it's a way to get the > current Standard File Current Folder. I don't see that anywhere -- > am I missing something ? It's the return value of macfs.SetFolder(). > BTW: For the original question, how about making os.getcwd() into > a wrapper around the existing getcwd(), with a no-arg-optional > behaviour that calls GetDirectory ?

ANN: NumPy 1.6 distributions for Mac
by Just van Rossum Oct. 27, 1998

Oct. 27, 1998

I've put a binary distribution of NumPy 1.6 for MacPython 1.5.1 at: <ftp://starship.skyport.net/pub/crew/just/Numerical_1.6_Mac.sit.hqx> and CodeWarrior stuff for people who want to build it themselves here: <ftp://starship.skyport.net/pub/crew/just/Numerical_CodeWarrior.sit.hqx> Note that the latter is just a folder containing a CW project and some .exp files, it merely supplements the official LLNL sources. Oh, it is PPC-only, sorry. Just

mac.chdir ?
by Steven D. Majewski Oct. 27, 1998

Oct. 27, 1998

I would love it if we could find a place in the standard library for a function that does the following one liner: os.chdir( macfs.GetDirectory()[0].as_pathname() ) Only problem: I don't know where it should go. macfs seems the logical place, however, it's a builtin, not a .py file module. Alternatively: maybe a better way of linking the "current directory" returned by os.getcwd() and used by other Python file functions with the "magic" placeholder use by the Mac standard file dialogs. ( If there's any interest in the latter solution, I'll look up what we changed in XlispStat to make it track better. However, that only works if the Mac Control Panel is set to "Take me to folder set by the application" ) ---| Steven D.

Re: NumPy Again!

Just and Heintz, I too am very interested in getting NumPy1.6 & Python1.51 for Mac! Could some kind soal send me a copy? Perhaps I can help too: I have CW3 on my mac. I'm not a real Mac hacker yet; more of a NeXTStep person. But if you send me appropriate project I might be able to compile. Earl Spillar spillar(a)uwyo.edu

Hi you all, I'm looking for maclib documentation (.html format) but I can't find where to download it from. I've got the pdf version but I prefer the html (better to browse) Is it somewhere?? thanks, JoanCarles...Typerware®

NumPy again
by Heinz-Guenter Hermanns Oct. 27, 1998

Oct. 27, 1998

Hello, a short time ago there was a discussion about further supporting NumPy for the Mac. I am not an experienced programmer but i have CW2 and would like to help supporting it. Could anyone give a summery of the state of the art? Does anyone allready have new versions of NumPy? Please do not throw your CW projects away. Please send them to me.

GUI suggestion?
by Bill Dozier Oct. 25, 1998

Oct. 25, 1998

Hi all, I'm still working on my MIDI-sysex librarian/editor (if anyone has a contact at Roland-Japan and can get a sysex map for the VG-8, I'd be ever so grateful!) and will soon be ready to start on a user interface. What I would love to do is to allow the user to drag & drop patches between windows to build collections of patches and within a window to reorder them. I guess that I would be displaying columnar lists of patch names & numbers. For reference, I have not done any GUI stuff outside of Tk on UNIX and OpenStep. Does the Framework module have enough in it for this kind of thing, or do I have to build the GUI in PowerPlant and make my own interface for it to Python? I am not happy with the appearance or stability of the Mac Tk port, so I'd rather go native. I don't think Tk supports drag & drop, anyway. Any suggestions, pointers to examples, etc. would be appreciated. Thanks, Bill Bill Dozier Mortgage Physicist

Re: [Pythonmac-SIG] MPW

If this is the only showstopper it can possibly be solved: GUSI still includes the projects to build an MPW library. I'm not 100% sure though what this means, it could either mean (a) a CW-formatted library for use in CW-projects to build MPW tools, or (b) an MPW-formatted library for use in MPW. Does anyone know for sure whether the library format is the same for MPW and CW? And, of course, it should also still be possible to build Python without GUSI. I haven't done it for a long time, but I can't imagine that there are big problems (probably just a few oversights, things that should have been inside #ifdef USE_GUSI). -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)cwi.nl | ++++ if you agree copy these lines to your sig ++++ http://www.cwi.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm
