elementary puzzle
by Charles Hartman Nov. 18, 2005

Nov. 18, 2005

--and off-topic too: I never work in Windows except to build distros, which I haven't done for a while. I have an app that works find in OSX and that works fine from inside the WingIDE, but when I use setup.py py2exe to build it and InnoSetup to make an installer, and then try to run the result, I get this: Traceback (most recent call last): File "c:\python24\lib\site-packages\py2exe\boot_common.py", line 69, in ? import linecache zipimport.ZipImportError: can't find module 'linecache' Traceback (most recent call last): File "pyprose.py", line 6, in ? File "os.pyc", line 62, in ? zipimport.ZipImportError: can't find module 'ntpath' Both linecache and ntpath are available in the Build directory parallel to the Dist one. What really, really simple step am I forgetting about?? Charles Hartman

py2app and PIL question
by Chris Jerdonek Nov. 18, 2005

Nov. 18, 2005

I have a python program that uses some commands from the PIL module (and also wxPython). I have PIL installed on my Mac, and the python program works fine when I run the program from the command line. The application I get from py2app also works fine -- until I get to a point in the program that requires PIL. Does anyone have any idea why I'm getting this error message? I can see the ImageFont.pyc in a subdirectory of the build directory that py2app created. Thanks for any help anybody can provide, Chris Traceback (most recent call last): File "/Users/chris/Desktop/ER/StoveTop/Old/dist/stovetop.app/Contents/ Resources/Python/stovetop.py", line 205, in Click item.Activate(frame, event) File "reports.pyc", line 326, in GenerateReport File "reports.pyc", line 154, in makePie File "graph.pyc", line 202, in __init__ File "PIL/ImageFont.pyc", line 202, in truetype File "PIL/ImageFont.pyc", line 121, in __init__ IOError: cannot open resource

xcode/pyobjc
by David Reed Nov. 17, 2005

Nov. 17, 2005

I'm getting ready to attempt my first real Cocoa app. I notice XCode has an option for creating pyobjc apps (when it asks you what type of app you want to create). I tried this but am not certain I'm using it correctly - build and go is not active. I did go into the directory and type "python setup.py py2app" and .app in the build directory seemed to open ok. Is the preferred way to create the Cocoa pyobjc app directly using XCode (if so, any ideas on why build and go isn't active for me) or is the best way to follow the tutorial example where you just create a normal Cocoa Objective-C app, design the interface, and then run nibclassbuilder and create the setup.py file by hand? Thanks, Dave

simple pyobjc question
by Tom Elliott Nov. 16, 2005

Nov. 16, 2005

I have 2 classes, one which responds to user input, calculates stuff and displays the result in a series of NSTextFields, and a second class that is a subclass of NSView called MyView, which can display the same type of information graphically. What I'd like is for the first class to be able to use MyView to display its results, but I don't know how to get them to talk to each other. If I had an instance of MyView I could pass in data and call setNeedsDisplay(True) via a button in the interface. How should I do this? Tom Elliott

book recommendation
by David Reed Nov. 16, 2005

Nov. 16, 2005

I've an experienced Python programmer on Linux - I've mainly used gtk and glade for interfaces and now I'm slowly trying to get started with Cocoa apps on X-Code. I've got the CurrencyConverter example working in Python and I did the HelloWorld example in "The Mac XCode 2 Book" by Cohen and Cohen in Objective C. I got the Python version working by guessing that I needed to use: self.helloSayer.setStringValue_("Hello world") based on the CurrencyConverter example that did: setFloatValue_ That was pretty obvious, but I think I need a Cocoa book that allows me to see what all the methods are for a given object. I've just started the above mentioned XCode 2 book, but it doesn't appear to have the details of all the Cocoa objects. Does anyone have a recommendation for another book I should get - I assume I want a Cocoa book of some sort. Thanks, Dave

I'm happy to announce that ActivePython 2.4.2 is now available for free download from: http://www.ActiveState.com/Products/ActivePython/ This release updates ActivePython to version 2.4.2, that was finalized a few weeks ago. My apologies for the tardiness. If you'll believe it, I've been busy implementing *Ruby* AutoComplete in Komodo. One thing you may not have noticed is that ActivePython has added support for a number of platforms in the past months. Installers are available for the following operating systems and architectures: - Windows/x86 - Mac OS X/powerpc (new) - Linux/x86 - Solaris/SPARC - Solaris/x86 (new) - AIX/powerpc (new) - HP-UX/PA-RISC (new) We would welcome any and all feedback to: ActivePython-feedback(a)ActiveState.com Please file bugs against ActivePython at: http://bugs.ActiveState.com/ActivePython What is ActivePython? --------------------- ActivePython is ActiveState's quality-assured binary distribution of Python. Builds for AIX, HP-UX, Linux, Mac OS X, Solaris, and Windows are made freely available. ActivePython includes the Python core and core extensions (zlib 1.2.3, bzip2 1.0.2, bsddb 4.2.52, Tk 8.4.9, and Tix 8.1.4) and is fully compatible with other Python distributions of the same version. ActivePython also includes a wealth of Python documentation, including: - the core Python docs; - Andrew Kuchling's "What's New in Python" series; - the Non-Programmer's Tutorial for Python; - Mark Pilgrim's excellent "Dive into Python"; and - a snapshot of the Python FAQs, HOWTOs, and PEPs. An online version of the docs can be found here: http://aspn.activestate.com/ASPN/docs/ActivePython/2.4/welcome.html Extra Bits ---------- ActivePython releases also include the following packages: - Windows "debug" package: Debug-built binaries for ActivePython users building debug versions of their binary Python extensions. - ActivePython24.chm: An MS compiled help collection of the full ActivePython documentation set. Linux users of applications such as xCHM might find this useful. This package is installed by default on Windows. These packages are available from: ftp://ftp.activestate.com/ActivePython/etc/ Thanks, and enjoy! Trent, Python Tech Lead -- Trent Mick TrentM(a)ActiveState.com

"PyObjCPointer created" messages and crash from tooltip handlers
by Michael Glassford Nov. 16, 2005

Nov. 16, 2005

I recently added outlineView_toolTipForCell_rect_tableColumn_item_mouseLocation_() and tableView_toolTipForCell_rect_tableColumn_row_mouseLocation_() handlers to a Py2App-based application and started seeing errors like the following being written to the console log: 2005-11-10 11:08:53.891 Goombah[990] PyObjCPointer created: at 0xbfffb570 of type {_NSRect={_NSPoint=ff}{_NSSize=ff}}@i{_NSPoint=ff} That's the only effect I see on my Tiger machine, but on another machine that's running either Jaguar or Panther (I'd have to check), the application also crashes unless these handlers are removed. Can anyone suggest how to fix or work around these issues? Thanks, Mike

It would be really nice if Apple had all the documentation in the header files, so that documentation in different formats (like Apple's current docs, or like Java html docs, or whatever) could be autogenerated, in particular so that people could generate whatever kind of docs they wanted. If that were the case, it should even be easy to even generate PyObjC-syntax docs for the frameworks. What the heck, I'll post it as a bug on http://bugreport.apple.com just for fun. -- // jack // http://www.nuthole.com

Re: [Pythonmac-SIG] Calling python application from AppScript

You'd need to use aem instead: from aem import * Application(a).event('ascrpsbr', {'snam':'processevent', '----':['system', 'start']}).send() Anyway, the usual approach would be to define a standard AE handler, e.g. 'PCAVProE', with named parameters, '----' (direct) and 'Par2'. That allows you to write: Application(a).event('PCAVProE', {'----':'system', 'Par2':'start'}).send() or: tell application a set r to «event PCAVProE» "system" given «class Par2»:"start" end tell You can then add an aete/sdef resource to provide terminology for that command if you want.
