Perl Qt4

Description:

Creating this library we aimed to use the Perl functionality
as much as possible, but to make the syntax similar to C++ Qt4.
This allows to use the original Qt4 documentation.
All the list classes (QVector,QList) are replaced by the Perl arrays.
All the associated arrays (QMap,QHash,QPair) are replaced by Perl hashes.
The classes of modules are completely coincide with the corresponding ones of C++ Qt4.
One can use all the protected functions from the object classes (QObject children)
except of those that use *Private classes as input parameter.

It's advisable to study the examples attached before writing programs.
I have checked the efficiency of Perl Qt4 on Qt4.3.3 (ASP12-i386 (base on Fedora7) ).

Arhive contain several examples of code.

For install need Qt4 headers.




Changelog:

4.004
- add access to protected enums
- rewrite Makefile.PL
- fix bugs in QListWidget and with WId
- add examples/desktop/snapshot
- add modules into CPAN
4.000
- add access to protected function for object classes
- add call virtual function from C classes into perl
- fix bug with INOUT for static function

It get a compilation error :

QString.xs: In function ‘void XS_Qt__QStringRef_unicode(PerlInterpreter*, CV*)’:
QString.xs:1629: error: invalid conversion from ‘const QChar*’ to ‘QChar*’

After adding a const_cast in QString.xs, it compiles, but the tests fails:

t/01_QtCore.....................NOK 1
# Failed test 'use QtCore;'
# in t/01_QtCore.t at line 9.
# Tried to use 'QtCore'.

# at (eval 3) line 2

The perl module is linked to QtCore:
$ ldd blib/arch/auto/QtCore/QtCore.so | grep Qt
libQtCore.so.4 => /usr/lib/libQtCore.so.4 (0x00002ac0ab29b000)

This is on an up-to-date debian unstable x86_64, with gcc 4.2, Qt 4.3.2 and perl 5.8.8.

Also, I think there is a typo at line 12 of Makefile.PL:
$QtCore_path = $arcs{-qc};
(but $QtCore_path is not used in the file)

For const QChar need add
const QChar *<tab>O_OBJECT
in typemap
But this must was see (and make) create_xs script

I install fedora8 today and check it on Qt4.3

PS my email have in arhive.

I tested program with Qt4.3.2 (fedora8 i386) and Qt4.2.1 (CentOS5 x86_64). Problem found only with x86_64.

For fix const QChar I updated arhive QtCore-4.000.tar.bz2

I'm trying to compile your librarie with Mandriva Linux 2008.0 (Qt 4.3.3 and Perl 5.8.8) and Mandriva Linux Cooker (development version, Qt 4.3.3 and Perl 5.10).

It fails the same way in both distributions.

 QGraphicsWidget missing

I was trying to get it to work with Qt 4.4.0, which apparently doesn't work. I compiled with Qt 4.3.5, which compiles, but it doesn't seem like all the features are there. $widget->{children} always seems to return an empty array, and $listView->selectionModel() causes a segfault.

Wow. Perhaps if I want to manipulate a selectionModel, a 'use QItemSelectionModel' is in order.
