[PyQt] Unable to find file the content

[燕子]

I'm on Windows using Python 3.1,  PyQt-win-gpl-4.6.2,  sip-4.9.2  and Qt 4.5.3.

I have a working graphics primative library that I wrap with SIP. I'd like to add Qt
classes to my library, e.g. QString.

I've gotten the file of *.pyd by my sip file, but when I run my *.pyd ,I got nothing just like this:
 when I run it on python idle.(myqtlibtest is my module)
  
  
>>> import myqtlibtest
 
>>> help(myqtlibtest)
 
Help on module myqtlibtest:
 
 
 
NAME
 
    myqtlibtest
 
 
 
FILE
 
    c:\python31\dlls\myqtlibtest.pyd
 
 
 
 
 
>>> 


Any help? Thanks - susan
