Introduction

Prototype of PerlQT4 I am working on

Changelog

• 20071231 Working on API templates
• 20070606 Draft typemap generated
• 20070423 Class entity files generated from formatted QTEDI productions
• 20070315 ALL QTEDI productions formatted, ready for generating code
• 20070214 parse module Parse::QTEDI uploaded to CPAN
• 20070202 adaption on parser to get KDE3 headers passed
• 20070130 ALL headers in QT ver 4.2.2 passed
• 20070129 QtCore/{qglobal.h,qobject.h, qobjectdef.h} passed
• 20070127 QtCore/qglobal.h passed

Howto

1. done strip #include and #error macros in header file
2. done select macros by gcc preprocessor (#ifdef #else #endif)
3. done parse preprocessed header by Parse::QTEDI
4. done format QTEDI production into binding-make-specific look
5. done generate class entity files
6. generate binding code, automate type marshalling
7. apply language-specific features (tie on container class, operator override)
8. QT signal/slot semantics inside Perl (subclassing QT class in perl)

• All phases are connected by a GNU tranditional Makefile.

Sample Output

• phase 3: 01 and 02

• phase 4: 01 and 02

• phase 5: typemap_list and typemap_template

Give a Try

• # please make sure you have QT4 installed
• svn checkout http://dongxu.googlecode.com/svn/trunk/PerlQT PerlQT
• cd Parse-QTEDI && perl Makefile.PL && make && make test
• svn checkout http://dongxu.googlecode.com/svn/trunk/Parse-QTEDI Parse-QTEDI
• cd PerlQT
• make

Pitfall

• Currently this package only runs on Linux platform
