[vtkusers] VTK and QT Projects (QVTKWidget.h)

[Alex Southern]

Hi, Darshan

Thanks for your reply, although im a little confused by it so I would 
just like to clarify...

"you should probably include the QVTKWidget.h that is present in your 
bin folder rather than the source folder."

This statement suggests that I have already included the source header 
file from the source folder, which I don't think I have. If you have 
read something I have posted that suggests otherwise or maybe you have 
some previous experience to call upon either way could you please clarify.

As far as I am aware there is no connection from my current visual 
studio QT project, which compiles ok,  and my vtk installation. the 
problem is that when I add the vtkwidget to the my QT project gui in 
QTDesigner, visual studio results in the previously mentioned 
compilation errors. I beleive i need to configure my QT project to see 
the vtk build. If this should be done as Darshan suggests by including 
the VTK bin folder. Then my next question is, how do I set this up in 
Visual Studio 2008?  ... Thanks for still reading :)

In addition I should stress that both my qt and vtk installed builds are 
configured correctly and all examples particularly QTimageviewer as 
supplied with vtk examples works ok.

Cheers
Alex
