Thanks Anja. I am using visual studio 2005 as my IDE. I ran a simple
example. I clubbed the hello world example from qt and an image display
example from vtk together and then ran it using qmake. I wanted to make a
visual studio project so i ran the command:
'qmake -project -t vcapp -o helloworld.pro' <http://helloworld.pro>
this gave me a helloworld.pro file. I edited this file to include the path
etc and then ran qmake again. this gave me a .vcproj file which i opened in
visual studio and then build it there. Here I got all those errors.
The code I am using to test the working of vtk and qt together is as
follows:
-----
#include <QApplication>
#include <QPushButton>
#include "vtkRenderWindow.h"
#include "vtkRenderer.h"
#include "conio.h"
#include "vtkDICOMImageReader.h"
#include "vtkImageViewer2.h"
#include "vtkRenderWindowInteractor.h"
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QPushButton hello("Hello world!");
hello.resize(100, 30);
hello.show();
// return app.exec();
// }
//int main( int argc, char *argv[] )
//{
vtkDICOMImageReader *img1=vtkDICOMImageReader::New();
img1->SetFileName("D:\\testimages\\IM_00001.dcm");
vtkImageViewer2 * myviewer=vtkImageViewer2::New();
myviewer->SetInput(img1->GetOutput());
//myviewer->SetSize(720,540);
myviewer->SetColorWindow(2000);
myviewer->SetColorLevel(1500);
myviewer->Render();
vtkRenderWindowInteractor *iren=vtkRenderWindowInteractor::New();
iren->SetRenderWindow(myviewer->GetRenderWindow());
iren->Initialize();
iren->Start();
img1->Delete();
myviewer->Delete();
iren->Delete();
return app.exec();
}
------
And my modified helloworld.pro file looks like this:
----

# Automatically generated by qmake (2.00a) Fri Oct 13 12:20:39 2006

Am I missing something? Plz. help.
