With it, you're able to use eric again. OTOH, I'm too busy at the moment to investigate for a real fix to the issue. Interestingly, you're on win32. Could you document your environment a bit more, e.g. OS version, where do your packages Python, Qt, sip, and PyQt stem from, or how do you built them yourself (including logs, if possible). That would be really helpful to narrow down the circumstances, where this issue appears.. I am somewhat new to python and have been using IDLE. Figured I should up my game and start using an IDE and settled on using Eric4. I was able to get everything installed from the downloadable installation files but am hitting the same problem you appear to be seeing. Whenever I try to open a file or create a new file, I get the error 'sip.methoddescriptor' object is not callable. Oddly enough, the other problem I see is that I can't resize the Eric4 window horizontally (up and down works fine). Wouldn't expect this to be related, but in the interest of full disclosure. No it's not, and this sounds strange. You may want to play with the PyQt examples a bit to check for other deficits. If it helps, below is the gory details of what I'm seeing, which traces down to the same line you point to in your note. I am using Python 2.5 and thought perhaps I would upgrade to 2.6 in an attempt to fix this. However, since you are using 2.6 I thought I would check in with you first. Perhaps I should fall back to Eric4 v4.4.10 instead. No, this won't fix your issue, since it is something related to sip, or rather the way, that sip is built.

Begging-for-ideas-ly-yours, Pete As your test case is so simple, and that the only bug reports I've had for either SIP or PyQt are a couple related to pyuic, it suggests that the problem is the way you are building them. The build system is fully documented (OBS, you remember), and didn't changed since month. I don't play any really dirty games there. Two patches are applied (inherited from openSUSE builds, where they're used since ages): * disable RPATH * disable timestamping sip generated files The former is not needed and the latter is used by the build system to detect real changes to built packages: if they don't differ, they're quashed (in order to avoid too much churn, aka build storms). You might remember, that I asked you for a global persistent flag in sip to disable it generally: that would spare us the second patch. Since the OBS creates a defined build environment that only contains the defined build dependencies every time a package is build, this reduces the risk of misdirected side effects during build significantly. Using a package manager for the resulting packages eliminates the usual caveats of having stray builds lying around, dependency issues, and the like. All in all, it's a pretty robust production grade setup, that is also used to produce full distributions. Back to the issue. Still no bisection, but a few more data points: * it doesn't appear for basic Qt types like QDate * it's not related to QScintilla from PyQt4 import QtCore, QtGui class A(object): def __init__(self): # catch access a non existing attribute try: print self.a, type(self.a) except AttributeError: pass a = A() # derive from a sip wrapped class class B(QtCore.QDate): def __init__(self): super(B, self).__init__() try: print self.b, type(self.b) except AttributeError: pass b = B() #app = QtGui.QApplication([]) # derive from a sip wrapped class class C(QtCore.QObject): def __init__(self): super(C, self).__init__() # access a non existing attribute results in: # TypeError: 'sip.methoddescriptor' object is not callable try: print self.c, type(self.c) except AttributeError: pass c = C() results in Traceback (most recent call last): File sipinstance-v2.py, line 38, in module c = C() File sipinstance-v2.py, line 34, in __init__ print self.c, type(self.c) TypeError: 'sip.methoddescriptor' object is not callable Instancing QApplication or not doesn't seem to matter here, though.

It searches the Qt meta system for matching methods, and raises the AttributeError if that fails.

Dear Erik, On Sunday 06 February 2011, 21:08:26 e...@eebrown.com wrote: All, Thanks for the help. I had given up on Eric4 this morning and was working through some PyQt examples to get a better feel for this package. I've been using SPE (Stani's Python Editor) which is okay but was trying to use Eric both for it's name :) and in hopes of better autocompletion and help support. I applied the fix from your other post, adding a pass to the TypeError exception, and it seems to correct the problem. I've been able to open and run python files in eric4 just now without seeing the problem. So in that sense all seems to be well. I'm not sure what might be different about my environment. I am running Python 2.5 and backed into the Eric installation. I started with PySide and had this installed, but PySide is a beta and I later realized Eric depended on PyQt. So I uninstalled PySide and looked more closely at eric4. Here is a rough sequence of events that might have something to do with all this: 1. I downloaded the PyQt source (by accident) rather than the installer. 2. I hit a problem trying to run this in that Sip was missing. 3. So I went out and downloaded Sip (I think it was sip, it might have been qscintilla - not sure anymore) 4. This installed fine, so now I had Sip available. 5. Then Qt was missing and it didn't appear to be in any of the folders I had available. 6. So I went and downloaded the full Qt installer (which was rather large). 7. I installed Qt with no problems, and it appeared to run just fine (at least the demos did). 8. Returning to PyQt, I received an error that g++ was not accessible. It was at this point I realized that I had started with the source code for PyQt rather than the installer. I really didn't want to go down this road, so... 9. I downloaded the Windows installer for PyQt. 10. Now I was concerned that my versions wouldn't line up correctly with what the PyQt installer expected 11. So I uninstalled Qt 12. I got rid of my PyQt source and other code. 13. The I installed PyQt from the installer with no problems. 13. At this point I downloaded and installed eric4. 14. Then I hit the problem we've been discussing. I've no idea, how this procedure could be straightened out in order to lower the barriers for entering this wonderful environment. Early this morning I uninstalled eric4 (v11) and tried putting 4.4.10 on my machine thinking the prior version might work (makes no sense in retrospect, but seemed sensible at the time). I had the same problem, so at that point I gave up. With the fix (more of a hack, I agree), I am running eric4 v4.4.10 with Python 2.5. I started with 2.5 because the book I had used it as well. Hopefully, the authors name starts with Mark and ends with Summerfield. I suspect if I cleared everything out and started over with Python 2.6 or 2.7, it might clear out whatever file issues I may be seeing. I'm reluctant do this as I have a small project I want to work on and it's taken me two days to get to the point where I can work through the PyQt examples. So I'll probably stick with this for a while until I find a good reason to change. Going up to Python 2.6 or 2.7 shouldn't present any problems at all. Let me get the history straight: the issue, we're facing here is an absolute exception. Being involved in PyQt businesses since 10 years, this hadn't happen before, and hopefully will not happen again. What makes me love that project more than almost any other is its strive for deterministic behavior in such a complex environment (Python, Qt, multi platform), that cannot be fully deterministic by definition (since development time IS limited, and time is behaving nearly linearly on OUR usual space-time continuum). I try to help Phil to resolve this ASAP. By the way, Detlev, it doesn't look like the 4.4.12 files were published. I see the folder but no files. Might be a permission issue, since I am an outsider for the project. Sourceforge is still backing up from counter measurements because of infrastructure attacks: http://sourceforge.net/blog You might need to take the SVN road to a current eric.
