Re: [PyQt] [SIP] Segfault with nested template types
Follow up: after replacing code of pia_test() with
Test.pia.clear();
with everything else unchanged, this issue can still be reproduced.

How can I resolve this kind of issues?
Is this some kind of bug?
Thanks very much :)

[PyQt] Issue with PyQt4/5 and Qt 5.1
Hello, today I compiled the Qt 5.1 and built the latest stable releases of PyQt4 and PyQt5 against it. Now I am not able to start any QProcess. I executed the QProcess test program as contained in 'qtbase/tests/auto/corelib/io/qprocess'. This shows a complete success. However, if I execute the demo 'PyQt-gpl-5.0/examples/qtdemo', it doesn't work (starting assistant or any of the examples fail). What did I do wrong? The behavior is identical with PyQt4 and PyQt5.

[PyQt] [SIP] is there a Qt5 example for SIP?
Hi Phil, I am trying to see if SIP will help me with a task I'm trying to solve. I started out by trying the More Complex C++ Example in the docs. However, I'm using Qt5, and the example is for Qt4. I see the pyqtconfig is part of Qt4, but not Qt5. No problem, except pyqtconfig is pretty integrated into the example, and as a beginner, I'm not sure how to take pyqtconfig out. Is there a Qt5 example for SIP? Thanks! Brett ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

A minimal build system would just be a shell script that invoked sip then the C++ compiler then the linker. The only thing you need to consider is to use the right -t flags to sip and these can be found by introspecting current versions of PyQt.

Re: [PyQt] Problems with wrapping complex types using typedefs
For now, aside from directly writing code to wrap std::map std::pairint, int, std::vectorunsigned long this is the only way that works; either #define sipType_cell sipFindType(cell) #define sipType_idxx sipFindType(idxx) typedef std::pairint, int cell; typedef std::vectorunsigned long idxx; std::mapcell, idxx Test; or #define sipType_cell sipFindType(cell) typedef std::pairint, int cell; std::mapstd::pairint, int, idxx Test; causes segfaults. However, I still hope for a way to eradicate these disgusting segfaults without reintroducing those magic numbers in headers. Phil, could you help me? Thanks...

This code: std::mapstd::pairint, int, std::vectorunsigned long Test; fails because sip complains: sip: Test has an unsupported type - provide %GetCode and %SetCode while this code: typedef std::pairint, int cell; typedef std::vectorunsigned long idxx; std::mapcell, idxx Test; fails because the compiler complains like: error: 'sipType_cell' was not declared in this scope error: 'sipType_idxx' was not declared in this scope I searched Google for `python sip typedef' and found this message: http://www.riverbankcomputing.com/pipermail/pyqt/2011-January/029111.html It seems that adding something like: #define sipType_cell sipType_std_pair_1800_1800 #define sipType_idxx sipType_std_vector_2100 to the `%ModuleHeaderCode' section make everything runs well. However, this trick seems quite unreliable because these magic numbers (1800, 2100, etc.) might vary from version to version. So is there any elegant way to wrap these types? In addition, I personally think it is favourable to generate `sipType's for typedefs, because this can greatly simplify efforts on wrapping complex template types, such as those in my examples. -- My current OpenPGP key: 4096R/0xE18262B5D9BF213A (expires: 2017.1.1) D69C 1828 2BF2 755D C383 D7B2 E182 62B5 D9BF 213A ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
