Compiling PyObjC 2.0 trunk on 10.4

Luc Heinrich — 2008-11-12T20:17:48

Greetings, The PyObjC application I'm working on has to run on 10.4 and 10.5, which currently forces me to use PyObjC 1.4 on 10.4 to build the app, which recently started to cause some very weird performance issues so I would *really* like to use PyObjC 2 now. I'm trying to build the latest sources from trunk on 10.4 and I get errors with pyobjc-framework-Cocoa because: - NSUInteger does not exist on 10.4. - _CoreFoundation_CFBinaryHeap.m defines an NSObject category with no name, which gcc does not seem to like. Locally fixing these problems allows me to build pyobjc-framework- Cocoa, all the other pyobjc-framework that I want to use building just fine. But then I'm having the incomplete bridgesupport files problem. For example, this wouldn't work: from ExceptionHandling import NSLogAndHandleEveryExceptionMask So I try to regenerate the ExceptionHandling framework bridgesupport file using gen_bridge_metadata but I'm not sure what to do with the result. What should I do to be able t

proxy for a number behaving strangely

Paul Thomas — 2008-10-25T20:57:29

I'm sending a dictionary from Python to an ObjC method and one of the values is a number. Trouble is, I keep getting this error: ValueError: NSInvalidArgumentException - Class OC_PythonObject: no such selector: isNSString__ The following are trimmed down from the real code and I can't get simple examples to fail the way my code does. This implies that it's a problem in my code of course, but I'm hoping against hope that someone has seen just this error before or can at least tell me what the problem might be. The really strange thing (strange to me with my level of understanding) is that I found one case where it does work - and that is passing the index value returned by enumerate(). assume 'v' comes from enumerate(): myobj.sendDictionary_(dict(version=v)) # works x=v myobj.sendDictionary_(dict(version=x)) # works #all these fail... myobj.sendDictionary_(dict(version=v)) myobj.sendDictionary_(dict(version=v+1)) x=v+1 myobj.sendDictionary_(dict(version=x)) myobj.sendDictionary_(

NSProgressIndicator ignores incrementBy when calledusing performSelectorOnMainThread_withObject_waitUntilDone_

Johannes Scholz — 2008-10-25T16:46:26

I am trying to advance an NSProgressIndicator from a thread, therefor i am using performSelectorOnMainThread_withObject_waitUntilDone_ to have the incrementBy call done from the main thread. However while just calling progress_indicator.incrementBy_(some_value) works just as expected, progress_indicator. performSelectorOnMainThread_withObject_waitUntilDone_("incrementBy:", some_value, True) just does not seem to do anything. See the code below for an simple example. from Foundation import * import objc class controller(NSObject): progress_indicator = objc.IBOutlet() < at >objc.IBAction def go_(self, sender): # WORKS self.performSelectorOnMainThread_withObject_waitUntilDone_("test:", 25, True) # DOES NOT SEEM TO WORK self .progress_indicator .performSelectorOnMainThread_withObject_waitUntilDone_("incrementBy:", 25.0, True) def test_(self, x): print 'yaye', x What am I doing wrong?

PyObjC on Leopard

Dav Clark — 2008-10-18T23:44:45

Hi there, I spent quite a bit of time scouring the internet for answers, and there don't seem to be any... so now I put these to you: 1) The pyobjc website says Leopard users should install from svn trunk. Why? What (bad) happens if I use pyobjc 1.4 + python 2.5.2 (Framework, non-System) + Leopard (OSX 10.5.x)? 2) Is there anything that's simply an amazing improvement in 2.0 (for existing code that already works with 1.4)? 3) How the heck to I build 2.x PyObjC from the trunk. I've found threads where other's asked about this, but they never ended in an answer... FWIW - I'm interested in getting pyobjc into the Enthought Python Distribution - which requires compatibility with 10.4. So another angle on the above would be 4) Could I build pyobjc (mpkg or egg or what have you) that would work on both 10.4 and 10.5? Thanks!

Method Swizzling - class_getInstanceMethod

Saptarshi Guha — 2008-10-14T05:54:14

Hello, How exactly do I use this function? For example, This is a plugin in Python(Leopard 10.5.5), the principal class is Voo(see end of email). I load the bundle and instantiate it like this NSBundle *bun=[NSBundle bundleWithPath:< at >"/Users/yanger/toperuse/PyRu/ example2/dist/gigo.plugin"]; Class currPrincipalClass = [bun principalClass]; id ins=[[currPrincipalClass alloc] init]; (i'm basing this of PyRu) Voo is trying to swizzle goody method I added to PythonStuff. However, a) load is not run b) : 'module' object has no attribute 'class_getInstanceMethod' Any ideas what I should do? Thanks Saptarshi ==Python Bundle(gigo.py)== from Foundation import * from AppKit import * from Foundation import * import objc class PythonStuff(objc.Category(PythonStuff)): def mygoody(self): NSLog("Alpha betea") class Voo(NSObject): < at >classmethod def load(cls): NSLog("A") def init(self): super(Voo, self).init() NSLog("B:")

Mike Stathopoulos — 2008-10-14T03:17:54

Hi, Documentation on PyObjC is pretty sparse. I want to instantiate PyObjC classes in Objective-C objects. Any docs or example code would be much appreciated. If there's no documentation floating around out there, which header files in the framework should I get more aquatinted with?

class vs. instance attributes for IBOutlets

Joe Strout — 2008-10-12T14:12:20

I'm re-learning Python, and learning Cocoa and PyObjC all at the same time. So maybe this is silly question: The examples I've seen have the IBOutlets (and often data too) defined at the class level, like so: class ToDoListAppDelegate(NSObject): toDoTableView = objc.IBOutlet() newItemField = objc.IBOutlet() toDoList = [] But it occurred to me last night that this would be a problem in an NSObject class that might have more than one instance -- wouldn't apply to the app delegate, of course, but it could apply to a window controller. So I moved the toDoList (which is a mutable type) to the init function. Then, on a lark, I found I could move the IBOutlets there too, so it looks like this: class ToDoListAppDelegate(NSObject): def init(self): NSLog(u"init") self.toDoTableView = objc.IBOutlet() self.newItemField = objc.IBOutlet() self = super(ToDoListAppDelegate, self).init() if self is not None: self.toDoList = [] ret

Build app under 10.5 XCode to run on earlier systems?

David Eppstein — 2008-10-05T18:12:51

If I have a PyObjC application built using XCode with the default Python installation and default XCode templates under OS X version 10.5 (example: http://www.ics.uci.edu/~eppstein/LaTeX_Unicodifier.dmg.gz, although I actually care about a more complex app I'm working on that is not yet ready for public release), the built app does not include any of the standard Python framework or libraries and will therefore not run under earlier versions of the OS that did not come with PyObjC preinstalled. Is there an easy way to convince XCode to make a more universal application? A related question: if I want my app to use psyco, it seems easy enough to add a few lines in main.py attempting to import and run that module, and doing nothing if the import fails. But that will only give a speedup on systems in which psyco has already been installed. Is there an easy way to convince XCode to include psyco within the build? ------------------------------------------------------------------------- This SF.Net email is spon

NSWindow launched from statusItem menuItem does notappear

David Mytton — 2008-10-05T15:08:21

Hi, I have a statusItem based application written in PyObjC. The statusItem has a menuItem which is supposed to launch a new window when it is clicked. In my AppDelegate.py ... menuitem = NSMenuItem.alloc().initWithTitle_action_keyEquivalent_('Preferences', 'launchPreferences:', '') menu.addItem_(menuitem) ... The launchPreferences method: def launchPreferences_(self, notification): NSLog('AppDelegate: launchPreferences') self.preferences = Preferences.alloc().init() self.preferences.showWindow_(self) which is creating a new object from Preferences.py class Preferences(NSWindowController): where I have: def init(self): NSLog('Preferences: init') self = super(Preferences, self).init() self.initWithWindowNibName_('Preferences') return self When I run the application in XCode (Build & Go), this works fine. However, when I run the built .app file externally from XCode, the statusItem and menuItem appear as expected but when I click on the Preferences menu

Build a NSview without the nib file.

Daniele Basile — 2008-10-02T13:27:56

Hi, I'am develop an application that must receive tablet event. To do this I write a simple pyobjc application that instance the NSView subclass and redefine the method that I would manage. The my problem is: Can I use directly python function to instance NSView, without the nib file? In Other words, I want to launch my application without making a bundle and nib file. I want use directly pyobjc to build my view and use it. thanks.

newbie questions about PyObjC

Joe Strout — 2008-10-02T21:42:29

I last used Python years ago, but now I'm considering it again. Mac application development is very important to my work, so this led me to PyObjC. But I'm confused on a few points... 1. The 2008-05-27 status update says that it doesn't support 10.4.... yet the "status" area says that PyObjC supports 10.3.9 and later, and I see that PyObjC 2.0 not only supports 10.5, but it's actually included with the OS. So which is it? Is 10.4 supported or not? 2. The "Examples" area of the web site talks about some great-sounding examples... but where do I get them? (They don't seem to match up to the folders in /Developer/Examples/Python/PyObjC/.) 3. How do I run the examples in /Developer/Examples/Python/PyObjC/? None of the folders seem to contain a prebuilt executable, and the "read me" files usually don't make much sense. For example, the one in PyObjC/Cocoa/AppKit/DatePicker directs me to run the "supplied XCode project," but there isn't any. I tried cd'ing to that directory and d

PyObjC, OpenGL & XCode

Black — 2008-09-27T15:35:57

Hopefully someone can help me out here. I am, as the subject suggests, trying to get OpenGL and PyObjC to play nice. I have been successful in the past using the general format of the OpenGL example included in the PyObjC distribution, but I have found that I was having some trouble with modifying it due to the new Interface Builder. As a result, I decided to give the new XCode based approach a go. I created a new document based python application and then generally followed the path of the golden triangle demo in the OpenGL programming guide from the Apple dev center. That worked fine and I got a nice triangle displaying. The problem comes when I start to get a little more involved. My view is a subclass of NSOpenGLView and I want to be able to override the useful methods like prepareOpenGL and reshape. However, as soon as I add one of those functions (even if they don't do anything), the application breaks and this shows up in the console: 9/27/08 11:26:08 AM Analyzer[19022] **

Accessing ivars in objc parent class requiresobjc.getInstanceVariable() ?

s s — 2008-09-22T17:44:32

I'm creating a class in Python, inheriting from an objc base class using NSClassFromString(). I can't seem to access IBOutlets or ivars defined in the base class directly. I can use objc.get/setInstanceVariable to get at the ivars but IB can't see the parent class IBOutlets at all even though, if I try to redefine them I get an error that they're already defined. Is there any reason I should have to use a function to get at the ivars defined in the objc parent class? I've not been using PyObjc lately but I don't remember this being an issue before. Clues?

Disk imaging

Jeremy Reichman — 2008-09-18T14:28:16

I'm wondering if anyone has used pyobjc for creating or manipulating disk images. I assume that because the system's DiskImages.framework is in /System/Library/PrivateFrameworks that it's not a good idea to use it for an app/script. But, has anyone done something else for disk images with pyobjc? I think I'd rather go that route for an idea I have, if it's tenable, than calling the command line utility "hdiutil." Thanks!
