It is working fine...
Try adding the include folders for wxWidgets to the intellisense:
For me under Linux it contains:
Settings -> Tags Settings -> ctags -> include files
/usr/include/wx-2.9-unofficial
Once you have added the include paths, perform a full retag (it should be done automatically for you once you have updated the incldue paths)
Workspace -> Retag Workspace (full)
In addition and if your machine is strong enough (4 and more CPUs, Linux is recommended :P ) with relatively high memory you could enable clang as well
Settings -> Tags Settings -> clang -> Enable clang code completion
