[PyQt] Incompatible Sip module version crashes Python

Over the last few months I've been upgrading a number of applications from bindings created with SIP 4.7.3 to 4.12.2. I notice that if I run such an app using the new bindings and it finds the old SIP api module (sip.pyd on Windows), Python crashes. I've added a bit of code to the Python wrapper

[PyQt] SIP method args default ownership rules

Sorry, I used to know this but it's been a little while since I've done any SIPping & the docs on ownership are actually not explicit on this point. What are the default assumptions about the ownership of objects passed into or returned from SIP-generated methods? __

[PyQt] SIP bug? (typemaps, %Import)

Hi all, This is a bit odd as it's an application that appeared after a change in my .sip code, but it looks like a SIP bug. I get the same behavior with 4.7.3 and 4.7.9. Briefly: I have two modules, szg and szgexpt. szg is much the larger. szgexpt.sip begins with a %Import szg.sip ...and defin

Downgrading gcc and g++ from 4.2 to 4.1 decreased build time from about 15 minutes to 13.6 seconds. Thanks all, -Jim C. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

[PyQt] More recent g++ slows build time immensely

Hi all, I've been using SIP to generate bindings for Syzygy . Since we've been using GNU Make for everything, I've been running SIP with "-j 1" to generate a single .cpp file, which up til now has worked fine (with MinGW g++ 3.4.2 on Windows and whatever g++ co

[PyQt] SIP: passing exceptions Python -> C++

I've got a C++ class with a whole bunch of virtual methods that are overridden in Python subclasses. These methods are callbacks, i.e. they're called repeatedly from a C++ event loop. I want to catch any Python exceptions raised in any of these callbacks, print the error messages, and then raise

[PyQt] Almost done with the switch to SIP

I'm about 80% through converting the Python bindings for Syzygy (cross-platform, PC-cluster VR, www.isl.uiuc.edu/syzygy.htm) from SWIG to SIP. The source is about 40% smaller, much more readable, and framerates are noticeably higher. SIP rules. -Jim C. ___

[PyQt] SIP newbie question (%MethodCode oddity)

Hi all, I'm fiddling with SIP 4.7.3 on XP for a non-Qt-related project. As a learning exercise I tried porting the Fraction example at to SIP 4. Got it working to a first approximation, but there's a bit that puzzles me: sipCpp doesn't always get defi
