[vtkusers] QVTKWidget linking problem

[Jim]

I solved this problem by myself by adding QVTK.lib to Linker | Input | Additional Dependencies. However, there are two new problems:
 
1) From Release Build, QVTKWidget won't refresh, i.e., it captures some random screen image and stays unchaged. Three Qt-VTK examples (release build) run without any issues.
2) Debug Build won't run (nothing pops up on the screen). This same problem happened to three Qt-VTK examples.
 
I am sure I have right PATH and VC++ Directories (Include files and library files) for both VKT and Qt. What am I missing here?
 
Thank you.

Dear vtkusers, 
  
Thank you all for your help. I built VTK 5.2.1 in VS2008 Pro and all examples, including three Qt examples, run successfully. I added QVTKWidget plugin to Qt Toolbox in VS2008. One thing I learned is that you can't add QVTKWidget plugin to Qt Toolbox if you build VTK with Qt 4.5.0. VS Integration 1.4.3 does not recognize any widget plugin built with Qt 4.5.0 which is newer than VS Integ 1.4.3. 
  
Now I am building a "Hello World" example in VS 2008 with Qt integration. Here is my system configuration: 
  
1) New Project --> Qt Projects --> Qt Application 
2) Project Name: AddressBook, then click Finish button 
3) Build F7. Everything went OK and I saw a blank main window on the screen. 
4) Drag and drop a QVTKWidget on QMainWindow 
5) F5 or F7 
6) I got the following 35 error message. 
  
I tried including all kinds of QVTKWidget stuffs to my project but all failed. What is wrong? 
  
Thank you. 
Jim
