Could you CC this to the list ? It rejects my posts, and the admins of
the list server do not seem interested in fixing the problem.

There currently  isn't a way to do this. You need to use %MemberCode, use
a try/catch  block, and then use PyErr_SetString() or something to set up
a python  exception.

This would be a *very* useful feature. At present, anything that can throw
needs %MemberCode, because if an exception "escapes" a C++ call, the
interpreter aborts. At the very least, it might be worth having an option
for each function that puts the body code in a try {  } block to suppress
exceptions.

In fact I had fixed the bug. I just had not rebuilt PyQt properly.

So to recap:

QSqlCursor calls QSqlQuery::afterSeek() instead of  QSqlCursor::afterSeek() 
giving a cursor full of zeros. This is fixed by uncommenting void 
afterSeek(); in qsqlcursor.sip and doing a complete rebuild.

Another small problem I found is that 'make rebuild-src' is broken in 
PyQt-3.0.

I had a go at debugging this and think I've found the problem.

cur = QSqlCursor( "places_table" )
cur.select( "name='burridge'" )
while cur.next():
print cur.value("id").toString()

The call to cur.next() calls afterSeek() but it calls the base class 
QSqlQuery::afterSeek() which is empty instead of QSqlCursor::afterSeek() 
which calls sync() to get the data for the cursor. No call to sync() = all 
zeros in the cursor.

I checked this by running the same code in C++ and sync() is called correctly.

I looked at the sip file for QSqlCursor and afterSeek() is commented out ? I 
tried uncommenting but the problem remains.

I'm stuck now because I don't know what to do to the sip files to get things 
working. 

Can Phil tell me what to do next please.

Jon.

[PyKDE] Error generated when wrapping a class derived from QCanvasView

[Jon]

Hello

If I create a small test c++ class for SIP wrapping, derived from 
QCanvasView. I get the following error when importing the extension module 
into Python. 

undefined symbol: sipCast_QCanvasView__FPCvP7_object

If I change the class so that its derived from QScrollView the error goes 
away.

I have done nm libqtcanvascmodule-3.0.so and both the QCanvasView and 
QScrollView symbols are listed.

Does anybody have an idea what could be wrong ?

[PyKDE] Problem returning a QString

[Jon]

Hello

I am having a problem with the code shown below. I wrap the JJTest C++ class 
with no SIP build errors. In Python I call str1() still no errors. But when I 
try and print with str() I get the error shown.  The Python documentation 
says this error occurs because there are unicode chars in the sting returned 
by str1() - but there isnt and if I change str() to unicode() I get the same 
error.

I compared my str1() function with PyQt's QButton.caption() function and the 
C++ and SIP file layout is exactly the same. If I replace str1() with 
QButton.caption() the error goes away - I dont see what Im doing wrong.

[PyKDE] sip-3.0 complains about not finding qt.sip

[Jon]

Hello

I have installed PyQt-3.0 and sip-3.0, both compiled with no errors.

But I get errors using a sip file that built ok on previous versions. SIP 
complains about not finding qt.sip (where my sip file has %Import qt.sip).

There is no qt.sip in the PyQt sip directory. Has something changed in 
version 3 ? and if so, what do I put in place of %Import qt.sip.

Hello Gerard

I upgraded to PyQt 2.5 and SIP 2.5. Heres what I got.

As you can see python setup.py build_ext gave an error.

[john@localhost PyMMM-0.0.1]$ python setup.py build_ext
running build_ext

g++ -E -I/usr/include/python2.1 -o MMM/moc_sipMMMProxyMMM.h
g++: No input files
error: command 'g++' failed with exit status 1

Same with --force on the end.

If I run python setup.py build_ext again I get this:

[john@localhost PyMMM-0.0.1]$ python setup.py build_ext
running build_ext
skipping MMM/MMM.py (inputs unchanged)
building 'libMMMcmodule' extension
error: file 'MMM/moc_CCC.cpp' does not exist

till I manually delete stuff to force a full rebuild.

and trying to run the example gives:

[john@localhost PyMMM-0.0.1]$ python examples/xmmm.py
Traceback (most recent call last):
  File "examples/xmmm.py", line 17, in ?
from MMM import *
ImportError: No module named MMM

I checked all the variables in setup.py and they did not need changing.

Am I doing something stupid ?

You said the readme explains the patch. It mentions a patch but does not say what to 
do to apply it. I have not been doing Linux for long so I need dummy instructions for 
this ?

Does running python setup.py build_ext apply the patch ?

Hello Gerard

Must admit I did not bother to go back and prove what I said about -fno-rtti, anyway 
its working.

Yes Il be happy to return the favor, but Im not on sip-2.5 so it will take a little 
time.

I tried PyQt 2.5 and Sip2.5 about a week ago and had problems, but Ill try it again 
(Ive learned alot in that week).

Ill download ftp://old-labs.polycnrs-gre.fr/pub/SAS/Vermeulen/PyMMM-0.0.1.tar.gz now 
and get back to you ASAP.

I have spent tonight trying to integrate the sip stuff into a KDE Studio Gold project 
as this where I do all my c++ programming. Once thats complete I should have a nice 
environment to work in.

Hello Gerard

Thanks again for all your help.

I carefully went through your email and tried everything you said but no luck.

1. Yes, I generate a new Makefile.am etc. below is the script I use to pick up changes 
in MMM.sip. I used PyQy and qtgl project files as a starting point for 
autoconf/automake/configure stuff.

2. Yes I get "gcc -shared CCC.lo MMMcmodule.lo..."   (you said CCCcmodule.lo ?) output 
shown below.

3. strings CCC.lo did not find __ti3CCC  (NM lists it as U).

4. Dont know about rtti so I tried both ways, -frtti gives the __ti3CCC error.  
-fno-rtti gives (all listings below are with -fno-rtti):

5. I Changed back to libtool 1.4

6. I deleted *.la in site-packages and  /usr/lib/libsip*.la

This is driving me mad. I thought if I started with a very simple example, it would be

[PyKDE] Help needed with SIP

[Jon]

Hello 

Thanks for the help Gerard. 

I added:

MMM_SOURCE = \
    CCC.cpp \
    $S \
    MMM.py

as suggested but get the same error:

Traceback (most recent call last):
  File "MMM.py", line 6, in ?
    import libMMMc
ImportError: /usr/lib/python2.1/site-packages/libMMMcmodule.so: undefined symbol: 
__ti3CCC

I changed to libtool 1.4 because someone said it might help. With libtool version 
1.3.5 I get the following error:

Traceback (most recent call last):
  File "", line 1, in ?
  File "/usr/lib/python2.1/site-packages/MMM.py", line 6, in ?
import libMMMc
ImportError: /usr/lib/python2.1/site-packages/libMMMcmodule.so: undefined symbol: 
sipName_qt_destroyed

So Im still stuck.

Hello

I have the same problem that Joerg JKaercher reported 8 Jun 2001, unfortunatly his 
email conversation with Phil did not seem to come to any conclusion. So Im stuck.

I compile my extension (source below) with no error, then get the following error when 
importing:

Traceback (most recent call last):
  File "MMM.py", line 6, in ?
import libMMMc
ImportError: /usr/lib/python2.1/site-packages/libMMMcmodule.so: undefined symbol:

  File "MMM.py", line 6, in ?

ImportError: /usr/lib/python2.1/site-packages/libMMMcmodule.so: undefined symbol:

My system is:
Dell Inspiron 8000
Mandrake 8.0

QT 2.3.0
KDEDIR = /usr
QTDIR = /usr/lib/qt2
