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) ).
For install need Qt4 headers.Last 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
I tried compiling it but it fails. Also, I tried converting the RPMs to the .pkg.tar.gz format that Arch Linux uses, but when I tried the example it failed because Perl Qt4 is 2-bit (my machine is 64-bit).
Hi,
I'm using strawberry perl on windows and through CPAN I tried to install QTCore, but it says : Error: can not found Qt4 headers
CPAN Logs are attached:
CPAN: Parse::CPAN::Meta loaded ok (v1.40)

I am using Ubuntu 7.10. I used the Synaptic Package Manager to install Qt4, and I am trying to use cpan (and "install QtCore", "install QtGui") to install the QtCore and QtGui modules. The Qt4 includes are installed on my system (/usr/include/qt4), but both cpan installation attempts fail ("Can not found Qt4 headers"). I have even tried creating links named /usr/include/Qt and /usr/include/qt to point to /usr/include/qt4, but no luck.
Please help!
Dear Vadim,
I installed Qt4.4.3 open source (OSX) and downloaded QtCore and QtGui. Qt is installed in the "/usr/local/Trolltech/Qt-4.4.3". There are several dir's in this directory:
bin doc include mkspecs plugins translations
demos examples lib phrasebooks q3porting.xml
Which directory do I need to declare for the -i option?
I don't understand the -qc option. After Qt4.4.3 instalation of the src files there are no *.core files. Are they created through the Makefile.pl? The QtCore and QtGui are located in my ./Sites folder. The QtCore.pm is in the "./Sites/QtCore-4.004/lib/QtCore.pm" folder. Which folder do I need to declare for the -qc option?

Please be aware that the Makefile.PL (for QtCore) has a bug which prevents it from using the qc setting:
In line 31 we have:
$QtCore_path = $arcs{-qc};
but it should be
$QtCore_path = $args{-qc};
$arcs instead of $args.
use strict and use warning would avoid this.
Hope it helps
Hi Sven,
the parameter -qc should point to the source directory of your Qt corelib:
-i ../whatever/Qtxx/include -qc ../whatever/Qtxx/src/corelib
but I cannot really check your problem as I am not using Mac.
If it's not working what qt-version do you use?

On debian etch with qt-4.2.1
After installing both QtCore and QtGui, when running the t1 tutorial from the examples, perl segfaults. The backtrace is:

Any idea on how to overcome this?

Hello! Is project still alive?
Are you ?
I tried compiling it but it fails. Also, I tried converting the RPMs to the .pkg.tar.gz format that Arch Linux uses, but when I tried the example it failed because Perl Qt4 is 2-bit (my machine is 64-bit).

see README file for install PS I updated files on CPAN

Thanks, it does help. But it did not answer my question. What do I need to pass as options to install QtCore? Regards Sven

What is your system: i386 or x86_64?
i386 $ uname -a Linux debian 2.6.18-4-486 #1 Wed May 9 22:23:40 UTC 2007 i686 GNU/Linux
Do the examples from QtCore work (QSize.pl, App1.pl)?
Yes, the examples in QtCore work flawlessly
I think, I find bug in QApplicationPrivate. If all ok, I update source for download.
The newer version no longer segfaults for me with QtGui examples. Nice!
