[CEDET-devel] Completion problem with Qt

[Hannu K. <az...@ik...>]

Greetings,

#include <QKeyEvent>


int main()
{
    Qt::Ke<M-x semantic-analyze-debug-assist RET>
}

=>

---------------------------------------------------------------
Cannot find prefix "Ke" in datatype:
  namespace Qt {}
Semantic may not have found all possible namespaces with
the name Qt.  You can debug the entire typecache, including
merged namespaces with the command:

  M-x semanticdb-typecache-dump RET   [ Do It ]

Possible completions are:
  enum Key {}
  enum KeyboardModifier {}


Known members of Qt:
  "enum GlobalColor {}"
  ...
  "enum Key {}"
  ...  
---------------------------------------------------------------

What does "Cannot find prefix "Ke" in datatype: namespace Qt {}"
mean?  Below it seems to list completions beginning with "Ke"
anyway.

The actual problem:

#include <QKeyEvent>


int main()
{
    Qt::Key<M-x semantic-analyze-debug-assist RET>
}

=>

---------------------------------------------------------------
Unable to find datatype for: "enum Key {}".
Declared type is: "enum"

Semantic could not find this data type in any of its global tables.
---------------------------------------------------------------

So if I try to complete Qt::Ke, it can find enum Key {}, but if I
try to complete Qt::Key, it cannot find it?  It also no longer can
find Qt::KeyboardModifier.

Difficult to interpret, this is.

I'm using CEDET from CVS and Qt 4.6 with configuration for CEDET as
follows:

(defvar qt4-include-base-dir
  (if (file-exists-p "~/sroot/usr/include/qt4")
      "~/sroot/usr/include/qt4"
    "/usr/include/qt4"))

(defun se::setup-ede-projects ()
  (interactive)
  ;; Qt4
  (loop for dir in (directory-files qt4-include-base-dir t "^Q")
        do (semantic-add-system-include dir 'c++-mode))
  (semantic-add-system-include qt4-include-base-dir 'c++-mode)
  (add-to-list 'auto-mode-alist (cons (expand-file-name qt4-include-base-dir) 'c++-mode))
  (add-to-list 'semantic-lex-c-preprocessor-symbol-file (concat qt4-include-base-dir "/Qt/qconfig.h"))
  (add-to-list 'semantic-lex-c-preprocessor-symbol-file (concat qt4-include-base-dir "/Qt/qconfig-dist.h"))
  (add-to-list 'semantic-lex-c-preprocessor-symbol-file (concat qt4-include-base-dir "/Qt/qglobal.h")))

Any ideas?
