Graphing capablility in Mac Python
by Anthony M. Ingraldi Aug. 23, 1998

Aug. 23, 1998

Hello, Is there a module available that will provide routines for creating simple line graphs and scatter plots? I was thinking of using AppleEvents to send data to KaleidaGraph or some other package but that seems sluggish. Another alternative would be to use a Canvas widget from Tk. I would prefer to use a module designed specifically for plotting rather than writing one via Tkinter. -- Tony Ingraldi | e-mail: A.M.INGRALDI(a)LaRC.NASA.GOV NASA Langley Research Center | Mail Stop 267 | Phone : (757) 864-3039 Hampton, VA 23681-0001 | Fax : (757) 864-7892 _______________ PYTHONMAC-SIG - SIG on Python for the Apple Macintosh send messages to: pythonmac-sig(a)python.org administrivia to: pythonmac-sig-request(a)python.org _______________

Administratrivia: ptyhonmac-sig is moved to mailman
by Jack Jansen March 20, 1998

March 20, 1998

Folks, real soon now the list will move from being managed by majordomo to listman, which is a much nicer package (and written in Python). When the list has moved you'll all get a message with instructions on how to use listman, plus your password for changing options, etc. Hopefully this move will not cause any problems, but just to be sure I'll post a message to the new list early next week. So, if you do see this message and you don't see the one next week: contact me and I'll see what went wrong. -- 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 _______________ PYTHONMAC-SIG - SIG on Python for the Apple Macintosh send messages to: pythonmac-sig(a)python.org administrivia to: pythonmac-sig-request(a)python.org _______________

Medusa under MacPython?
by FoulCraven March 19, 1998

March 19, 1998

Has anyone successfully gotten Sam Rushing's Medusa to work under MacPython? More specifically, 1.5b3? I get an error in the macpath, which says that the path it is trying to work on begins with '::' and I have not been able to find the source of the problem.

Tkinter vs. native calls
by Fernando Garcia March 19, 1998

March 19, 1998

Hello I'm mostly a newbie onf Python on the Mac, although I've long experience with Macintosh programming. The basic guestion is what to use: Tkinter or the native OS calls that Jack gave us to handle menus, windows, etc, etc, etc. The first one will gave me compatibility across platform (suposing I don't use any Mac specific feature, like QuickTime), the later one will create a more Mac native app. I've never worked with Tk (less with Tk on the Mac) and I don't know how Tk Mac applications looks or how they integrate with the standard user interface. Any insights on this?

tk corrupting Finder
by John Slater March 17, 1998

March 17, 1998

I am trying to use tcl&tk. This has resulted in my having to reinstall OS 8.0 (on a G3) several times because the finder got corrupted and I could not even restart my machine (error type 41). I don't know how to "bless" a copy of the system folder, so this whole reinstall business gets laborious in a hurry. Anyways, at this point it seems like menusare doing the dirty deeds. This code is very suspect: frame .mbar -borderwidth 1 -relief raised pack .mbar -fill x menubutton .mbar.file -text "File" -menu .mbar.file.m pack .mbar.file -side left menu .mbar.file.m .mbar.file.m add command -label "Exit" -command exit menubutton .mbar.edit -text "Edit" -menu .mbar.edit.m pack .mbar.edit -side left menu .mbar.edit.m .mbar.edit.m add command -label "Clear" -command { .sketchpad delete all } I noticed in the 1.5b3 README that " Other outstanding problems are tkinter problems with menus (all platforms) " is mentioned. The tcl/tk 8.0 Mac release README does not mention any problems with menus, but it seems likely that there is a fundamental problem with tk - not a problem with tkinter. I will try to get the attention of someone at Sun - if there is anyone in the tcl group that is still there. I live a half mile from Sun, so there can't be any excuses about non-reproducability, they will be welcome to look at my computer. If any of you are interested in this outcome, let me know. Also, if anyone is reading "Effective Tcl/Tk Programming" and wants to port some of the programs to Python, send me mail since I will do some of this if I can get tk to work on a Mac. -John _______________ PYTHONMAC-SIG - SIG on Python for the Apple Macintosh send messages to: pythonmac-sig(a)python.org administrivia to: pythonmac-sig-request(a)python.org _______________

cfm68k Python 1.5b3, who uses it?
by Jack Jansen March 11, 1998

March 11, 1998

Well, since the release of MacPython 1.5b3 I have made only very limited progress on the cfm68k bugs (packages not working and NumPy crashing), and I don't really see any way forward either: I don't have a reasonable 68k machine anymore, and single-stepping Python on a 16 Mhz 68020 with 4Mb of memory and no disk to speak of is _no_ _fun_. So, I'm planning to release a final 1.5 for the mac with these two bugs still unresolved. But, before I do that I would like to hear from people how much trouble these bugs are causing them, if any. -- 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 _______________ PYTHONMAC-SIG - SIG on Python for the Apple Macintosh send messages to: pythonmac-sig(a)python.org administrivia to: pythonmac-sig-request(a)python.org _______________

MacSpeech
by Mark Alford March 6, 1998

March 6, 1998

I'm sorry about my earlier "missent" attempt. Please ignore it. Here is a clearer description of my problem. I've been having a problem using Tkinter and MacSpeech together, on a PowerPC laptop. I'm running Mac System 8, with Python 1.5b3. I've created a script that displays the problem (see below). On the laptop, this script invariably dies the *second* time I run it. How it dies depends on how much memory is allocated to Python. Usually it freezes up the whole machine, or gives "error type 112". I'd be very grateful if anyone else could verify that this happens (and perhaps suggest a cure...) The laptop is a Powerbook 3400c, with 80M of RAM. #----------- Example script, dies on *second* running ----------- from Tkinter import * import macspeech class MacSpeaker: # taken and simplified from grail.py in Mac speech demo def __init__(self): self.voices = [] self.nvoices = macspeech.CountVoices() self.curvoice = 1 def _newvoice(self): vd = macspeech.GetIndVoice(self.curvoice) sc = vd.NewChannel() self.curvoice = self.curvoice + 1 if self.curvoice > self.nvoices: self.curvoice = 1 return sc def newvoices(self, n): self.voices = [] for i in range(n): self.voices.append(self._newvoice()) # The class for the main window: class Box(Frame): def __init__(self, parent=None): Frame.__init__(self, parent) self.speaker = MacSpeaker() # open up the speaker nv = self.speaker.nvoices print nv # Here is where it freezes upon the second running if nv is 22, # the full number of voices available # *******>>>>>> self.speaker.newvoices(nv) bb = Box() bb.mainloop() #--------------- End of example script -------------------- ---------------------------------------------------------------------- Mark Alford School of Natural Sciences Institute for Advanced Study Princeton, NJ 08540 U.S.A. ---------------------------------------------------------------------- _______________ PYTHONMAC-SIG - SIG on Python for the Apple Macintosh send messages to: pythonmac-sig(a)python.org administrivia to: pythonmac-sig-request(a)python.org _______________

Missent

This one was missent to the pythonmac-sig-request address. Please reply to the original author (or the list), not to me... ------- Forwarded Message Date: 4 Mar 1998 16:26:48 -0000 From: "Mark Alford" <alford(a)ias.edu> Subject: Tkinter chokes Laptop I've been using Tkinter to write a GUI application. I'm running Mac System 8 on a PowerPC laptop and a Performa. On the laptop, my application invariably freezes up the *second* time I run it, during the Frame.__init__ . I then have to reboot the machine. I am using Python 1.5b3, but this used to happen with Python 1.33 as well. On the Performa, this doesn't happen, although it does occasionally die with "error 10" for no apparent reason. The laptop is a Powerbook 3400c, with 80M of RAM. Any suggestions for things to try? - --------------------------------------------------------------------------- Mark Alford School of Natural Sciences Institute for Advanced Study Princeton, NJ 08540 U.S.A. - ---------------------------------------------------------------------- ------- End of Forwarded Message _______________ PYTHONMAC-SIG - SIG on Python for the Apple Macintosh send messages to: pythonmac-sig(a)python.org administrivia to: pythonmac-sig-request(a)python.org _______________

Floating window

I'm new to Python so sorry if this doesn't make sense. Can anyone tell me how to create a application window that will always stay on top of other applications. In TK or preferably in native calls.
