PyObjC had very limited support for GNUstep, but that never worked properly and because nobody was interested in finishing the port I ripped that support out.

If someone really wants gnustep support and is willing to support that I'm willing to merge a patch to that effect. However, that person will have to do all the work, I'm will not merge partial patches or even run tests on Linux (which means a linux maintainer will have to fix the linux port from time to time because development on OSX broke linux support).

PyObjC does not support linux, and probably never will.  The core part of PyObjC is a bridge that translates Python method calls into Objective-C calls (and the other way around). This bridge uses the Objective-C runtime and the API for that is not standardized in any way, the GNU runtime (used by GNUstep on Linux) has a different API  than the one on OSX. 

Adding support for GNUstep on Linux is possible, but I'm not interested in doing the work.

I believe at one point PyObjC supported GNUStep
(http://www.gnustep.org), but it does not anymore. In other words,
PyObjC will unfortunately not be very useful to a Linux user. The
value proposition for PyObjC, for better or worse, is entirely to the
benefit of MacOS X developers who wish to interact with Cocoa using
Python.

I think for making a 2d game using Python, you'll have a lot of great
(read: better) options:

This is a huge departure from making a simple 2d game. :) Can't help

[Pyobjc-dev] About linux Support.

Today I found about pyobjc, and I'm pretty interested on it just
because i like learning about different programming languages.
Now, I want to learn objective c and to do it I'll write a very simple
2d game with it. The problem is I'm a linux user. I _know_ pyobjc is
mac focused, but maybe you have some kind of support to linux?

Or maybe you can tell me where is the subset of the code (maybe the

[Pyobjc-dev] Build hell resolved: 10.4/10.5/10.6

[Aahz <aa...@py...>]

[cross-posted to both pythonmac-sig and pyobjc-dev for max audience,
Reply-To set to pyobjc-dev for discussion]

I finally figured out how to build my app:

Turns out that in order to use PyObjC 2.2 you need py2app 0.4.3 -- but
PyObjC 1.4 needs py2app 0.3.6.  (PyObjC 1.4 is for the main app running
on 10.4/10.5/10.6; PyObjC 2.2 is used for FSEvents on 10.5/10.6,
previously PyObjC 2.2b2 for 10.5 only, but 2.2b2 doesn't work on 10.6)

I built PyObjC 2.2 on 10.5 from source.  It's a right royal pain (partly
because PyPI has no mechanism for downloading *source* dependencies), and
I really hope that the next release of PyObjC makes it much easier to
build from source.  (Or that binaries for 10.5 get included.)

My clue that py2app was the issue was when I figured out that 

from Foundation import NSAutoreleasePool, NSMutableArray, NSString

causing

ValueError: Don't know CF type for typestr '^{__CFAllocator=}', cannot create special wrapper

only and always occurred in a build, not from plain Python, even on 10.6,
meaning that PyObjC wasn't the problem.  

Incidentally, using py2app 0.4.3 with PyObjC 1.4 resulted in some error
about corrupted NIB file that I didn't record exactly.

Before someone asks how I can use both PyObjC 1.4 and PyObjC 2.2, I'm
playing games with ~/Library/Python/2.6 being a symlink that gets swapped
during the build process.  (Obviously, I end up with two different apps
built.)

I found the absolute best resource to be Cocoa Programming for Mac OS X, by Aaron Hillegass. I simply ignored all of the memory management stuff and used PyObjC rather than ObjC. The only gotcha I remember is adding @endSheetMethod onto things such as openPanelDidEnd_returnCode_contextInfo_().

Just wanted to give this thread a bump. I am still blocked by this
issue, and any responses, workarounds, insights or otherwise would be
greatly appreciated!

To restate the problem, I am implementing an informal protocol
"ISyncSessionDriverDataSource". One of the methods to be implemented
simply returns an enum value (in other words, an int) -- and the Sync
Services framework complains no matter which of the acceptable enum
values I return. Either I'm missing something (it's happened before)
or there is a possible bug with with the bridge's SyncServices
framework support.

Apologies for bumping this with not much new to add, but I am very
keen to get this issue resolved. :)

Cheers,
Mani

[Pyobjc-dev] Spotty luck with demos

[Jim C. <ji...@ma...>]

I'm trying to figure out if I should be using PyObjC instead of
wxPython for Mac apps...  but I'm having trouble getting started.  In
the demo files, I'm able to run Grady, and ClassBrowser but not
OpenGLDemo, which fails with the error, "(ArgumentError: argument 3
<type 'exceptions.TypeError'>: wrong type)  and when I try DotView,
the app immediately quits without ever showing.

I'm on SnowLeopard on a 64 bit macbook (but running 32 bit everything)
using a Framework install of Python 2.6. I installed PyObjC=2.2 using
easy_install, and py2app 0.3.6.  I do have pyOpenGL installed, and can
run wxPython OpenGL apps.

I'm completely impressed with Miro, which uses PyObjC to embed VLC,
and has a decent startup time, and generally works like a charm... but
can't seem to find the path to writing similar apps myself.  What are
the best resources for getting started?

'from Foundation import *' should help, but does indeed not do so :-(

This is fixed in the repository, but that's not usable at the moment due to a port-in-progress to python 3.x

[Pyobjc-dev] Constant not found

[Tobias W. <mk...@to...>]

Hi,
using the Python and PyObjC that came with Snow Leopard, this works fine:

from Foundation import *

NSURL.URLByResolvingBookmarkData_options_relativeToURL_bookmarkDataIsStale_error_(
    mydata, (1 << 8), None, None, None)

But I'd rather use the named constant NSURLBookmarkResolutionWithoutUI, only I'm getting NameError.

I found a suggestion to import * from AppKit, but that doesn't help:

[Pyobjc-dev] Bluetooth in non-blocking application with Qt user interface

[Lukas H. <Lu...@gm...>]

Hello,

I need your help porting my application Series60-Remote [1] to Mac OS X.
It is an open source software suite for S60 mobile phones, which is written in 
Python. Its GUI is based on PyQt4 [2] and it uses Bluetooth to connect to a 
mobile phone.

I tried to port this application to Mac OS X using lightblue as bluetooth 
wrapper for IOBluetooth. I tried to handle the bluetooth connection in a 
seperate thread (like in Linux and Windows) [3], but this seems to be not 
possible with IOBluetooth.

My next try was to use an asynchronous connection instead and use IOBluetooth 
directly. It works great with the attached Objective-C application [4]. 
But how can I use this wrapper in my Python application?
When I import this extension using objc I already have the Qt event loop 
running. But I also have to start the Cocoa event loop (CFRunLoopRun()) if I 
want to receive rfcommChannelData and rfcommChannelOpenComplete events?
Is it possible to integrate this event loop in Qt, like it is possible to 
integrate the Qt event loop in GTK+?

Did anybody try something like this? Are there any examples?

[I know this issue isn't directly related to PyObjc, but maybe anybody has 
done a similar thing?]

Thank you for every help,
Lukas Hetzenecker

[Pyobjc-dev] Problems implementing a protocol

[Mani G. <ma...@tu...>]

Hello,

This may or may not be a bridge bug, but either way I'll post it here
and hopefully someone will be able to help.

I am implementing a Python class (note: not a subclass of NSObject)
that fulfills the ISyncSessionDriverDataSource protocol
(http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Reference/ISyncSessionDriverDataSource_Protocol/Reference/Reference.html).

With this implementation passed in to the session driver, I've
confirmed that functions in my class returning various Cocoa objects
(NSDictionary, NSArray, NSURL) are being invoked and handled
correctly.

However, I am stuck on the preferredSyncModeForEntityName_()
implementation. It is supposed to return type ISyncSessionDriverMode
(http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Reference/ISyncSessionDriverDataSource_Protocol/Reference/Reference.html#//apple_ref/doc/c_ref/ISyncSessionDriverMode),
an enum.

My code simply returns an enum value:

Initial Comment:
I've often gotten errors like:


/usr/bin/strip: the __LINKEDIT segment does not cover the end of the file (can't be processed) in: /Users/cbarker/HAZMAT/MappingSVN/Maproom/trunk/dist/Maproom.app/Contents/Frameworks/GDAL.framework/Versions/1.6/Programs/gdaltindex (for architecture ppc)



They go away if I blow away the previously built app bundle and run it clean.

This isn't too big a deal, but I often forget, and then I stare at it while before I remember what to do about it.

Just to make sure, is the same code running under plain Obj-C? You might be dealing with some Core Animation change.

Other than that, I know that CAAnimations have a property on what to do when the animation finishes (remove, freeze) and so on. You'd need to see the docs for more specifics though.

Re: [Pyobjc-dev] import Quartz in 10.5 Xcode Project headache

[Chris B. <qu...@me...>]

I'm having some trouble getting your workaround to function as well;  
the application launches properly if I take the Quartz import out of  
the global scope and put it in my method or in  
applicationDidFinishLaunching_, but the animation is still not  
working... Allow me to demonstrate:

import objc
from Foundation import *

class ShakeDemo(NSObject):
   window = objc.IBOutlet()
   def applicationDidFinishLaunching_(self, sender):
     import Quartz
     NSLog("Application did finish launching.")
		
   @objc.IBAction
   def shake_(self, sender):
     import Quartz
     shake = {'count': 4, 'duration': 0.5, 'vigor': 0.05}
     shakeAnim = Quartz.CAKeyframeAnimation.animation()
     shakePath = Quartz.CGPathCreateMutable()
     frame = self.window.frame()
     Quartz.CGPathMoveToPoint(shakePath, None, NSMinX(frame),  
NSMinY(frame))
     shakeLeft = NSMinX(frame) - frame.size.width * shake['vigor']
     shakeRight = NSMinX(frame) + frame.size.width * shake['vigor']
     for i in range(shake['count']):
       Quartz.CGPathAddLineToPoint(shakePath, None, shakeLeft,  
NSMinY(frame))
       Quartz.CGPathAddLineToPoint(shakePath, None, shakeRight,  
NSMinY(frame))
       Quartz.CGPathCloseSubpath(shakePath)
     # Use KVO to set the path and duration since we "can't change a  
method"
     shakeAnim._['path'] = shakePath
     shakeAnim._['duration'] = shake['duration']
      
self 
.window 
.setAnimations_(NSDictionary.dictionaryWithObject_forKey_(shakeAnim,  
"frameOrigin"))
     self.window.animator().setFrameOrigin_(frame.origin)

if __name__ == "__main__":
   from PyObjCTools import AppHelper
   AppHelper.runEventLoop()

This works perfectly on Snow Leopard, but when I run it on Leopard the  
window disappears after the shake_ action (its frame turns into  
NSZeroRect rather than animating as far as I can tell). Obviously,  
ShakeDemo.window outlet is wired to the window in the xib, as is the  
shake_ action, so I've attached a project file below so you can try  
for yourself.

Thanks!  If you can at least specify the revision you used to create 2.2,
I can pull trunk to that rev.

This is a known issue, though I've no idea whose bug it is. 

The workaround is to put any Quartz-related imports in a place where they are reached *after* the application launches,
such as applicationDidFinishLaunching_. If you're doing a lot of work you might move them to an external file to make life easier.

[Pyobjc-dev] import Quartz in 10.5 Xcode Project headache

[Chris B. <qu...@me...>]

I'm trying to use Quartz in my Xcode template-based PyObjC application  
to do a window shake animation; everything works great in Snow  
Leopard. When I go about testing it on Leopard systems, some bad stuff  
happens at application launch, the dock icon bounces continuously, and  
the console barfs up this nonsense before quieting down and doing  
nothing at all:

_RegisterApplication(), FAILED TO establish the default connection to  
the WindowServer, _CGSDefaultConnection() is NULL.
*** -[NSRecursiveLock unlock]: lock (<NSRecursiveLock: 0x1d66300>  
'(null)') unlocked when not locked
*** Break on _NSLockError() to debug.
NSInternalInconsistencyException - Error (1002) creating CGSWindow

This issue doesn't occur if the import occurs after  
AppHelper.runEventLoop() gets called, but the resulting calls to  
Quartz don't appear to be functioning properly, as the window does not  
shake and in fact disappears, changing its frame to NSZeroRect for  
every frame of the key-animation.

I've tested this import issue on a clean Xcode project from the  
template and it occurs, but the internets at large have little to say  
about the matter outside of the py2app realm. Any thoughts/ 
workarounds? The fact that this works just fine on Snow Leopard leads  
me to believe that this is a bug with PyObjC in Leopard, but I really  
hope not.

Re: [Pyobjc-dev] QTKit with Python 2.6.4 and Snow Leopard?

[Jep H. <je...@gm...>]

Hi Ronald,

You actually already solved this when you pointed out that the 'in_attrs' string wasn't being properly defined as an NS dictionary. Once you do that, it all works....


def convert_for_iphone(infile, outfile):
    in_attrs = NSDictionary.dictionaryWithDictionary_({
        'QTMovieFileNameAttribute': infile,
        'QTMovieOpenAsyncOKAttribute': False,
        'QTMovieApertureModeAttribute': QTMovieApertureModeClean,
        'QTMovieIsActiveAttribute': True,
        })

    movie, error = QTMovie.movieWithAttributes_error_(in_attrs, None)


Cheers,
Jep

Ouch. That sucks, I'll see if I can create an archive with all sources for the next release.
