Tooltips (and code completition) for wxWidgets

[marfi]

Hi, I've already read a topic dealing with tooltips for Win32API, but I can't find out how to make C:B to show tooltips (or to allow a code completition) for wxWidgets. I've enabled "Follow GLOBAL includes" in propertis dialog window of Code completition plugin, but it doesn't work (it looks like C:B doesn't parse any wxWidgets header file even if a path to these files is set in project properties ("Directories" pane in project's compiler settings - common settings for all build targets) (I use a custom variable WX_DIR for specification of a directory where a wxWidgets are installed).

What should I do to enable tooltips and code completition for wxWidgets' functions and classes?
