I use emacs 24.4 with auto-complete1.5.0 and bundled version of CEDET2.0 (I've also tried with latest CEDET by downloading and loading cedet-devel-load.el).
I have qt4 sources installed and semantic in my ac-sources. I want it to parse and auto-complete my sources.
Following Alex's Ott tuto I put this in my init.el :
(require 'semantic/sb)
(require 'semantic/ia)
(require 'semantic/bovine/gcc)
(require 'semantic/bovine/c)
(add-to-list 'semantic-default-submodes 'global-semanticdb-minor-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-highlight-func-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-local-symbol-highlight-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-scheduler-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-decoration-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-completions-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-summary-mode)
(add-to-list 'auto-mode-alist '("/usr/include/qt4" . c++-mode))
(semantic-add-system-include "/usr/include/qt4" 'c++-mode)
(semantic-add-system-include "/usr/include/qt4/QtGui" 'c++-mode)
(semantic-add-system-include "/usr/include/qt4/Qt" 'c++-mode)
;(add-to-list 'semantic-lex-c-preprocessor-symbol-file "/usr/include/qt4/Qt/qconfig.h")
;(add-to-list 'semantic-lex-c-preprocessor-symbol-file "/usr/include/qt4/Qt/qconfig-dist.h")
(semantic-mode 1)
But there's nothing to do, I don't get any completions !
-- Edit --
After some search I think the problem is that semantic doesn't parse qt sources as it should;
for example, I have :
#include <QSystemTrayIcon>
But when I try to complete "QSyst"... I have only one possible completion : QSystemTrayIconPrivate So I opened /usr/include/qt4/QtGui/qsystemtrayicon.h to see what's in this file and there is the definition of QSystemTrayIcon class:
class Q_GUI_EXPORT QSystemTrayIcon : public QObject
and the definition of QSystemTrayIconPrivate :
class QSystemTrayIconPrivate;
I don't know what this Q_GUI_EXPORT means, I have never seen such construction of class; with root powers, I modified the header to :
class QSystemTrayIcon : public QObject
then forced semantic to reparse and the completion works for this class now !
I deduce Semantic doesn't understand how qt creates classes, it's the same for other such as QApplication, and so on...
I don't want to manually edit all qt sources. So, is there a way to hack Semantic source code so it can understand this kind of class construction ?
