Designer Widget Box in Eclipse

Hello all-

I am trying to install QWT integrated with my Eclipse installation on 
Windows XP.  I have had Eclipse 3.3.1.1 installed for some time.  I 
installed the MinGW binary version of QT 4.3.4 (open source version), 
and had it refresh my MinGW installation since there was an issue with 
my w32api.h file.  I then installed QWT 5.0.2 using the instructions for 
a MinGW installation (i.e. qmake/make).  Then copied the resultant 
lib/qwt5.dll into the QT bin folder, lib/libqwt5.a into the QT lib 
folder, and the designer/plugins/designer/qwt_designer_plugin.dll and 
libqwt_designer_plugin.a files into the QT plugins/designer folder.  If 
I open Designer I see the QWT widgets in the Widget Box just fine.  I 
then installed the QT Eclipse Integration v1.0.1 and, when opening 
Eclipse with MinGW, I can open the Widget Box but it doesn't show the 
plugin widgets (no Arthur and no QWT widgets).  I suspect that there may 
be a more general problem with the integration between QT and Eclipse, 
but since one of the affected products is the QWT widgets I was hoping 
someone here had seen this before and knew how to deal with it.

Thanks
-Claus
