integrating qwt into qt creator

[pham_tv <tie...@gm...>]

I am trying to add qwt plugins into my Qt creator so that I can drag and drop
the qwt widgets onto my app.  I have installed qt creator and recompiled qwt in
released mode.  I then moved shared library files to the qt directories. Do I
have to re-compile Qt after I place the shared library in the Qt folder in order
to see the plugins via help->about plugins???  Please help!!!

- Thanks
